Can't decide on wheel/tyre size?

[JoeZ13]

Hi All,

After much deliberation I'm about to bite the bullet and purchase some 20" wheels for my RRS. I'm downgrading from 22" as I'm wanting to put all-terrain tyres on for some general beach and off-road use.

I've decided on ROH Blade wheels with Nitto Terra Grappler G2 tyres.

I've been given two configuration options:

a) ROH 20x10 with Nitto 285/50*20
b) ROH 20x8.5 with Nitto 275/55*20

Anyone able to recommend one size over the other?
My only concern is the sidewall difference. Was originally going with the 275/55 but the rep recommend I go with the wider wheel and 285/50.

Any help in finalising my decision is greatly appreciated.

I have a set of 275 55 20 Nitto Ridge Grapplers on my MY19 D5.

Very happy with them.

Was tossing up the 285's but wanted to keep width tolerances & the extra height of side wall.

Believe it or not have improved ride both on & off road.

[Gregz]

I would go for 275/55, which will give extra cm of sidewall over 285/50. Also those who have 275/55 report that the spare will fit in the hole in the boot ok. 285/50 may be a little too wide for the boot floor to sit flat?
I currently have 255/55 and will go to 275/55 when the current tyres wear out.

On any vehicle , increased sidewall height, ie aspect ratio increase , will give you better ride quality in all applications.

[JoeZ13]

I have decided to go with the 275/55 as i really want the extra sidewall but mounted on the 20*10 wheel.
I have been told that running the 275/55 on the 20*8.5 wheel will cause the tyre to balloon when airing down.

Apparently the 20*10 will sit better also on the car (as the 8.5 is too narrow) and no rubbing either.

Here's hoping all goes well. As almost all dealers are telling me to get the 285/50 tyre.
I trust the guys on this forum more though ;-)

Just need to confirm that the 20*10 will allow the floor to close flat when the spare wheel is in place?

[Graeme]

I would not like to fit my 275/55R20 AT+ currently on 8.5" standard rims to 10" rims because the sidewalls would be stretched to make them more vulnerable to damage. Any bulging when aired-down would be less on 8.5" rims than on 10". I really think that you've made the wrong choice of 275/55 on 10".

Thanks for this info. I have been researching all day whether the 275/55 will fit on 10" wide wheels and have found that the side walls will stretch. I haven't confirmed my purchase yet and called the dealer to confirm this info with him and he assures me they are fine. Not sure if it's to do with the ROH wheel design?
I may just revert to 8.5" and leave it at that. Price is exactly the same. He and other dealers have said that the wheels will sit a little inside and won't look as good as the 10".

Chuck- Ridge Grapplers not too noisy??

[chuck]

CSBrisie

I have found them to be good.

Little bit more noise than OEM tyres but you have to be listening for it with radio off.

Much better ride though

[Disco4SE]

On any vehicle , increased sidewall height, ie aspect ratio increase , will give you better ride quality in all applications.
Keep in mind that LT tyres have a stronger / stiffer sidewall, so you can actually get a harsher ride downsizing tyre diameter.

Likewise, some tyres (non LT) have a stronger sidewall than others.

Such a hard choice...........

Cheers, Craig

[JoeZ13]

Had another chat with a few wheel/tyre dealers today and all are giving me different information.

The one I'm looking to buy from has assured me that he does fit 275 tyres on 10" wheels. Apparently, it's popular among Commodore drivers.

Anyway, have decided if I'm going to stick with the 10" (my preference due to 45 offset) I may give the 285/50 a go.

Anyone have experience with 285/50r20?
I've been told that they may rub at full lock in access mode.

Hopefully someone else gets help from this thread in the future.

[Geedublya]

The stock 20" wheel is 8.5" with 47 offset. I run 275 55 20 on these with no issues. I thought about 285 50 20 but decided the added sidewall and diameter was the better uption. I'm pretty sure the 285s will fit fine as they run a 295 on the SVR.

I've deflated my 275s to 16 psi for beach driving and didn't notice excessive bulging, I think the 10" rims will be more susceptible to rim damage but if you stay away from rocks they should be OK.

Personally I would be looking for some genuine 8.5 x 20" wheels as these are cheap and have much better tyre holding when aired down, I also like the way the make my RRS look like a base model.

[Gregz]

Hi Geedublya, what brand/model 275 55 20 do you have and how do you like them?

[Geedublya]

Hi Geedublya, what brand/model 275 55 20 do you have and how do you like them?

I'm running Falken Wildpeak ATW3. I'm very happy with them, excellent grip on wet and dry blacktop, good ride quality and reasonable road noise (slight whine that my wife hasn't noticed). My one foray off-road didn't show any weaknesses.
I rate them much better than the Nitto Terra Grapplers I had previously.

[Gregz]

thanks Geedublya, how many km do you think you have done on them so far? I am tossing up between those and the Pirelli AT+ . but probably don't have to decide until later in the year. Falkens are winning over the Pirellis at the moment in my mind due to being something like $70 - $90 per tyre cheaper. Also, somebody reported that the AT+ tends to loose a bit of wet grip as the km increase (which I have previously experienced on their ATR tyre) , and maybe don't really want to go with them if that is the case.

[Graeme]

There haven't been any indications with my AT+ of the aquaplaning that occurred with the quite new ATRs on my D4 which is not surprising considering the ATRs provided no exit channels for water from the centre of the tread whereas the AT+ have wide paths to the edges. The ATW3 have a higher load rating than the AT+ in 275/55R20 size although my AT+ are harsh enough on gravel but the AT+ have relatively thin spots between the raised ribs right at the top of the sidewall below the edge of the tread, which I knew about before giving them a try but then had a new tyre pierced by a sharp piece of metal in that area that was not repairable, fortunately replaced by Pirelli FOC.

13K since September.

I ran 285/45 R20 and had to put a spacer on the front as they rubbed the suspension strut. Off Set needs attention as the clearance is an issue, I opted for Range Rover Wheels off earlier Model, load rating was good but offset was 2mm different and that was enough to rub.

[JoeZ13]

Update...

I've since taken the advice of many and have purchased a set of original Range Rover Sport 20" wheels.
I had originally been looking for a set (at a decent price) with no luck, but have now managed to find a set of 5.

I'm now tossing up whether to go the Nitto Terra Grappler G2 or Ridge Grappler. Both in 275/55r20.

The wheels will not be on the car all the time as i'm keeping the 22" for general day to day use and swapping them out when i head off-road.
This means i'm more inclined to go with the Ridge Grappler if i'm using them for off-road only as i like the fact they are a hybrid A/T & M/T.

Thanks to all for your input.
I'll keep you all posted on my decision.

You are doing the same as me, I have kept the 22 inch wheels. Am running the Nitto's but they do have a bit of noise compared to the OME 22's.

[chuck]

I've had both.

The Terra Grapplers on a D4

Ridge Grapplers on a D5

Go the Ridge Grapplers

Be careful though once you have them on you wont be bothered taking them off.

They will toughen that RRS up & you wont have to worry about your 22" rims anymore.

[JoeZ13]

Thanks Chuck!
I am swaying towards the Ridge Grapplers.

I know i won't be bothered changing them, but If i want my marriage to survive i'll need to ensure the 22" wheels go back on. She doesn't like the off-road look of the tyres on the RRS.

[discojools]

Just to weigh at the end of these posts. A few years ago I accompanied a friend in his 2014 RRS with 275/55/20 ATRs on a Simpson Desert/Hay River track trip. The tyres survived fine and airing down for the sand was not a problem. The car itself did the trip easier than my D4 and the 79 Cruiser. It was the most powerful, most comfortable and most efficient on the trip. Space in the car was a problem though but we got around that by having a frame made up that bolted into the tie down eyes and carried the fridge, water and fuel.
There are much better tyres now than the Pirellis.

[CSBrisie]

Also going down this path - Ridge Grappler for off road only. 22’s for day to day [emoji4]

Which year where the replacement rims from? were they from a non L494?

They were off a 2016 L494.

[georgien]

Has anybody experienced 265/60 R20 tires ? Any rubbing ?
I am privilege side wall height over tire width.

Thanks for your input !

[Traxover]

Just fitted Falken wildpeak at - 275 55 20” on my 2017 RRS (have my 21” for city and 20” for travel)

they a lot more quiet than I thought very happy with them.

they are very tight fit when lowered one finger in some areas. I would suggest 265 60 20” would not fit as they are bigger dia.

few pics attached lowered and raised

Next mission to add seconded battery in the rear side to run fridge

[discojools]

What’s the ride like?

[Traxover]

What’s the ride like?

ride is softer than the 21” I have. A lot better for touring long distance. 20” are Not racing tires definitely have roll when you hit corners hard.

[SBD4]

..... 20” are Not racing tires definitely have roll when you hit corners hard.

under steer can be a shocker if pushing on at recommended pressures with 20", but not too bad if pressures are up at around 38 PSI.... better tyre wear too. On road pressure of coarse. Doesn't give away too much in ride quality especially if loaded up a bit.

[discojools]

Never noticed that... both my RRSs have had 20" tyres. Always run at factory recommended pressures and never had a moment with those pressures including one big drive across the mountains. Had 2 very scary moments where tyres were overinflated after service, one was in the wet. One or 2 psi over is fine but over the ride suffers and grip is reduced especially in the wet IMHO. A movie stunt driver once told me that they overinflated tyres to make it look more spectacular.

[Pedro_The_Swift]

Seems like a good place to ask--

Speed rating of L494 tyres are?
and rim load rating?

[Tote]

Rim rating is 950KG on the 20" rims as you can see from this listing - have a look at the pictures, its cast on the rim GENUINE LAND ROVER 20" RANGE ROVER Sport Vogue Wheels RIMS - EXCELLENT | eBay (https://www.ebay.com.au/itm/GENUINE-LAND-ROVER-20-RANGE-ROVER-Sport-Vogue-Wheels-RIMS-EXCELLENT/324364175155?_trkparms=aid%3D1110012%26algo%3DSPLI CE.SOIPOST%26ao%3D1%26asc%3D20201210111451%26meid% 3D9a35e30c875e445cb015188005905eac%26pid%3D101196% 26rk%3D1%26rkt%3D12%26mehot%3Dnone%26sd%3D22420160 2736%26itm%3D324364175155%26pmt%3D1%26noa%3D0%26pg %3D2047675%26algv%3DPromotedSellersOtherItemsV2Wit hMLRv3%26brand%3DLand+Rover&_trksid=p2047675.c101196.m2219)

I guess it may depend on the tyre you have and the specs of the vehicle.

Mine is a TDV6 SE with no transfer case (high range only) giving a 60/40 torque split rear/front. If you have torque vectoring that will improve things too.

I am running 255/55R20 Pirelli Scorpion Verde A/Ts which came with the car (now on 2nd set at 158k km with 3mm to wear indicators - 1st went to 94k Kms). I ran the tyres at recommended pressures for the 1st 50k Km and found the middle of the tyre was not wearing as quickly as the outer edges so I upped the pressures. Doing that gave me more even wear and as a bonus, much better handling...with a bit harsher ride.

I found that the lower pressures gave a lot more tyre squeal while cornering at a lower speed threshold in the dry with mild understeer and in the wet, DSC kicking in quick smart. Note that this is when pushing it hard through tight bends. With the pressures up I don't experience the handling issues nearly as much.

I think if I had the pressure any higher I would certainly experience the same sketchy handling you mentioned. I think it must just be the sweet spot for this particular tyre on my car.

Of coarse, if I was just pottering along being a good boy all the time it wouldn't be a problem[bigwhistle]

[georgien]

Has anybody experienced 265/60 R20 with standard 20' rims ? Do they fit ?
Thanks

[Tote]

So I have acquired yet another set of rims..... These are 21s and have a bit of kerb rash but are perfectly usable. I had the 20" set on when I had my little excursion to Wakefield and these were offered to me as a spare set for a track day once I get the ATs put on the 20"rims. Since we are off on a road trip next week I thought I'd give them a run and see how they go
The rims are fitted with 275/45-21 Atturos, now I had never heard of these tyres but they seem to be Taiwanese made for the US market. I'm fairly impressed with them, they are quieter than the Pirellis on the 20" rims and the handling with the 21s is substantially better. I'd always thought of the 21s as a bit of a oddball size but these seem to tram track less than the Pirellis that are on the 22s and the vehicle feels substantially more planted than on the 20s

so,, The 20" rims on the D4 and RRS are the same?

[Pedro_The_Swift]

So Mr Tote,, you dont need your 20"anymore?.... [bighmmm][bigwhistle]

[Tote]

So Mr Tote,, you dont need your 20"anymore?.... [bighmmm][bigwhistle]

Oh yes I do, a set of (most probably) Falken 275/55-20 Wildpeaks is on the horizon. Then I can have some pictures of the RRS both on the track and off the track [biggrin]

[Pedro_The_Swift]

No,, thats incorrect...

"Then WE can have photos on and off track..." [wink11][bigrolf]

[Tote]

so,, The 20" rims on the D4 and RRS are the same?

I believe the offsets are different. there's some info on what fits on post 62 in this thread

L494 Off Road Tyres (https://www.aulro.com/afvb/l494-range-rover-sport/263207-l494-off-road-tyres-2.html)

I haven't done much research on the offsets for other RRS, FFRR and Disco rims but they all have the offset stamped on them so that helps if the seller can be bothered to take proper photos....

Edit - The link to tiresize.com in that post should have the offsests and rim size for the others

Hi Chris,

I ended up sourcing a set of Range Rover Sport OEM 20" wheels in black and fitted NITTO RIDGE GRAPPLERS LT275/55R20.
All up 5 wheels & 5 Tyres $3000.

I'm in Sydney. The wheels I found in Melbourne and the tyres locally.
I have only fitted them to my car in mid December after having them in storage for a while.
I have been to Stockton Beach but haven't tested them on trails yet.
At Stockton beach I ran tyre pressure at 20psi. It was first time with this size so had to guess but it ran perfectly. On road I'm running 38psi.

The NITTO RIDGE GRAPPLERS are definitely noisier and you will notice it coming from 22" Continental Cross Contact tyre setup.
Having said that the noise is not that annoying and you quickly get used to it. They are a bit sketchy on wet roads though and don't feel as planted as the Continental 22" tyre setup I was running.
I would be happy to leave the NITTO RIDGE GRAPPLERS on full time but my wife prefers the 22" look.

When I was up at Stockton Beach in early January the tyres fitted definitely got the attention of other 4wheelers. You can definitely see the aggressiveness on these tyres and it shocks a few people when you tell them you take the Range Rover Sport off-road. It definitely toughens the car up.

I went with the RIDGE GRAPPLERS as I am still keeping my 22" for general road use. If you're not going to swap between the 22" & 20" I would recommend the NITTO TERRA GRAPPLER G2 ALL TERRAIN as they are not as noisy.

If you need any other information then let me know.
