20”wheels L405

[orangepop]

Can anyone confirm please if I should be looking for 47 or 53 offset wheels . I’m wanting to replace the 21” with 20” so as to fit 55 profile tyres on My L405 SDV8

[Graeme]

53 was for the original L320 RRS, D3, D4 etc where the rims were set in further than on the L405/L494.

Thanks Graeme ... I’m bit thick so want to be sure before parting with $$$ , are you saying I need 47 Offset . [emoji848]

[Graeme]

I had in mind that the L405/L494 offset was 45 but perhaps that's just my not recalling exactly. The rims will have a part number that can be checked for applicability.

Edit: The standard 20"x8.5" rim for the MY13 L405 ALY72245U20/72265 Range Rover Wheel Silver #LR037745
has 47mm offset.

Thanks Graeme
The rims I’m looking at are off a 2014 RR Sport & are 47offset so I’ll inspect them and all going well part with some more cash . Cheers

[Graeme]

I just sent you a msg.

Ive now bought a 2nd hand set of 20" wheels off a L494 Sport (TICK) and will probably fit NITTO 275/55R20 tyres (TICK). The L405 Autobiography & current 21" wheels have TMPS but the 20" wheels don't have TPMS. Do I need to have the dealer Turn Off TPMS or will the car just ignore it as it wont be able communicate with wheel sensors. I do have an IIDTool but hesitate to get in too deep with it.

You can move the TPMS senders over to the new wheels or buy some more. If you don’t have senders in the wheels it won’t matter as the TPMS should just ignore it. It did on my D4.

You bought the correct wheels. [emoji1]

As for the tyres, Nittos probably wouldn’t be my first choice but they aren’t bad.

[orangepop]

Thanks , I’m not locked into Nitto but have seen a few posts suggesting they are good. What would you suggest?

My Pirelli AT+ in the same size are quiet. The AT+ has LI 113 whereas the TG has 117 although neither is classified as LT.

I’ve previously used the pirelli AT on a Sport & was happy with them, forgive my ignorance but what is the meaning of LI113 & TG127 Graeme

[Graeme]

LI is load index where the higher the number, the higher load it can carry.

The Pirelli AT+ is nothing like the original ATR other then being quiet. Pirelli addressed the short-comings of the ATR including a pattern with better gravel performance.

TG - Terra Grappler short-hand.

Thanks Graeme .... I’m taking all that in [emoji106]

Anyone here with in-depth knowledge of TPMS for RR ? I have kept my original wheels and tyres and fitted up a new set with 275/55/20's. When I priced new senders at the dealer the price was prohibitive, over 1k ! I purchased a "used" set from UK about $150 from memory. Fitted the tyres and waited for senders to connect - never happened. After market service guy here spent over half an hour with computer - no luck, and couldn't help. LR dealer here "thought" that I needed the numbers off the sender to enter in the computer - too late, tyres are fitted. So I have decided to wait until new tyres are due before trying again.
What I do know for certain is that operating without senders fitted is not a problem, occasionally when starting a message comes up TPMS not working, then disappears, no bells.
I would appreciate any advice available on the subject, maybe what I bought from UK was rubbish, (they were stamped LR parts).
Cheers, Peter

So Ive fitted the Pirelli AT+ to the 20" 494 wheels on my L405. They are certainly quiet, I can hardly pick the difference from the standard Continentals on the 21" wheel.

My spare is still the original 21"with 275/45/R21 which is much smaller overall diameter than the 275/55/R20 Pirelli AT+.
QUESTION : Is the 21" ok to use as a Spare or would that cause damage to the Diff / Transmission etc.

[Graeme]

I did a short test run up to 100 kph with a 30" 2nd spare tyre on the front while the others were 275/55R20 and was surprised that no faults occurred as I was expecting at least a steering angle fault. I vowed that it would only get used in an emergency and only for a short distance while waiting for a 275/55R20 puncture to be repaired. A 31" would only be half as bad but over time could still damage 2 diffs.

[CSBrisie]

Guys - is ET53 ok or do they need to be 47? I see a set of 4 on Gumtree but 53.

[Graeme]

ET53 suggests D4 or L320 RRS. The extra inwards offset will reduce the clearance on suspension components especially if the rims are from an RRS which usually have wider rims (9"?) than a D4 and your vehicle (8.5"?).

I fitted a set of 47 Offset off a 2015 L494.

Graeme is that 30” & 31” correct or a typo & should be 20” & 21”... I wasn’t aware of a 31” wheel.

He means with tyre included [emoji4]

Thanks .... it’s a steep learning curve [emoji45]

Hi orangepop,
I would suggest forking out the extra $ for a same size spare as the rest of the car. I think it is cheap insurance against what potentially go wrong if you were to drive any distance with different size tyres.
Interestingly, a year ago when I took my car in for a service, I asked them to swap the (until then unused) spare with a front wheel which I had kerbed. They were reluctant even though the tyres are all same model and size, saying that because the spare was unused it could cause some issues. They would however put the unused spare on the back, and moved a back wheel to the front and put the kerbed wheel into the spare hole. Food for thought I think.
By the way, I just had mine serviced again, and .... nothing to report, all good and boring.

Thanks Gregz, yes I’m of the track now ... hence the original question to make sure I wasn’t wasting time & money. I’ll need to get 2 spares as I always have one in the van for long trips .... easier to get to the van spare too. I’m also a Bit concerned that the 275/55r20 will fit in boot space [emoji848]. Always nice to get a clean bill of health at service time [emoji106] boring is good sometimes.

I’ve been told the 275/55/20 fits in floor ....equally keen to confirm before I fork out for 5xnew boots!

[BobD]

As I have said in another post the 275/55 R20 fits in the boot (spare wheel well) OK. I have one in my spare wheel well with no issues at all. Gordon told me that the 285 will fit also but the lid will sit on the tyre and be lifted a few mm off the floor. The 275 fits perfectly, however.

Like a glove 🧤, 275/55 20

[Graeme]

My 275/55R20 AT+ have passed my outback travel test even though I destroyed one and damaged the rim when at 40-50 kph I ran into a 6-8" high lump of embedded limestone hidden by a small bush near the edge of a rarely-used track. No problems with normal large rock pieces loose or embedded at 90 kph and apart from the wrecked one, no marks on the sidewalls and no obvious damage to the treads.

So I now have my 2 spares 47 Offset 20” rims off a current Sport [emoji736] but I had to buy a set of 4 so I’ll list the other 2 in the market place.
