18" wheels to 16" wheels

[CamRat]

Hi,

My d2a have 18" standard wheels. Does anyone know if I can pu 16" on as I want to go to Fraser island, but am worried that the low profile tires that are on now will not be any good in soft sand. I have told to only let them down to about 22 25 psi. I have done this but do not think it is enough to trundle through the really soft stuff. I have done rainbow beach with no hassles but sand is mostly hard along there. Does anyone have any ideas???

Any help appreciated.

Cheers

Cam

My D2a has 16" (235/70R16). No problems. I was under the impression the 16" are standard.

Plenty of fellas have gone to 16's mate. Its a smart move - though if you go to the D3/4 forum some may try to flame me for that...

Im sure there are people on here with 18's on D2's that do ok, but its a lot lighter than the D3/4 too I suppose.

Mate 16's are great in the sane - high profile, let down a bit and away you go.

Cheers

PS. You will be snatching people out of Indian with 16's

Cheers, my d2a has 18s as standard, and have been told the that disc brakes are to big to house 16s around. I have a hse v8 model, so not sure if the brake size is different to td5 models. I just don't think I am good enough in my rig as it's only 5 weeks old ( to me ) and I am still learning it. I will keep investigating as I am keen to find out I it's possible, even if I can have a set of 16 s for when I want to out for some fun in the soft stuff for the weekend. I have some American import mudders on now, which are great for dirt and rock..... But would like to use some road tires as this is my daily drive too...

The tires I have on now are 255/55/18. Not sure if I can increase wall size on the rims I have already.

[nice1guv]

I think someone is telling you porkies.

Most D2 and D2a's have 16 inch rims as standard, both Td5 and V8's.

Only the higher spec models came with 18 inch rims.

But AFAIK you can freely swap 18 and 16 and vice versa, Td5 or V8, no problems at all.

[Redback]

16s are no problem, the D2 and D2a came standard with 16x7, 16x8 and 18X8, discs are the same on all models, just make sure the tyre size is the same rolling diameter, standard is 29" to 29.5, 235/70/16, 245/70/16 and 255/55/18, or you could go bigger if you want, if your not doing a lot of offroad, then 245/70/16 is fine.

Just for your information, P38a Range Rover alloys are good at 16x8, cheap also at about $80 to $100 each.

I went from the 18's to the 16's on mine.

No problems at all with brakes, and the rubber is cheaper as well. I have 245/70/16 fitted.

Great in the sand, as you can air down a lot more than the 18's.

[CamRat]

Great, thanks all.. Will not be going back to that tyre shop again!!!

I guess The Internet will help me on this one, thanks again everyone!

Hi,
Just been through the same problem myself.
I have bought my 2000 Es V8. I purchased a set of Range Rover's from a P38. Got these from a tyre dealer. He was great. He was concerned that they would not fit either but checked before fitting. I had already told him that they would...after the same advice you have been asking from here. (have a look in the Discovery 2 section. I asked the same question. I have seen this statement several times..."search is your friend").
I got 265's.
Airing down...depends where you are...but can go much lower than -22-25psi.

15 PSI should be no problem and lower than that when required. You have to adjust driving style...no rally driving. Do some searches on here. I have found that people are really good at passing on the experience and advice.

Good Luck!

I had 18's on my 04 d2a and changed to 16's with 265/75/16 they fitted fine

Did you, notice any power loss on the td5 with the 265/75/16

I previously had the 18's and 255/55 R18 on my DII.

You would be surprised how well they actually work in sand. In some ways it was an easier drive than running the mud tyres I have now on the sand.

[scarry]

All the last of the D2a's,that is the "classics" came with 18's.

I left the 18's at the dealers,kept the 16's i had on the previous D2.

Swapped straight over no problems,have the same rolling diameter.

Best thing i ever did.

I saw a guy on Moreton isl. with 18's on a D2a in the real soft stuff & he was having heaps of drama's.Actually got badly bogged getting onto the ferry.They were on 16psi.
My 16's were also on 16psi,and i was struggling as well,but got through.

Just thinking,the 'classic town' definitely came with 18's,but the 'classic country' may have come with 16's.My memory is going with age:(

Correct.

[rockstar]

Correct x2!!

:D

I never figured out what made up the $5000 of extras on the "classic country"

The list I saw included the alloys but all D2a models came with alloys so not really an "extra". I guess the genuine cargo mat must be a really expensive item!!!

In fact all D2 models came with alloys except for a short run of "basic" models in 2002 (pre update) which had steel rims, no cruise and only four speakers (missing the tweeters in the A pillars).

For those of you who really are twisted some of the really early 99 models were missing the tweeters as well.

But anyway back on topic...

If you can be bothered swapping wheels before a big weekend get some 16s with MTs. MT/AT tires for 18s are crazy expensive.

I have no probs running 18's :cool:

Mud, Sand, Rock.... No issues :)

Never seen a D2 on 18's with stock tyre size have issues either - IF they know what they are doing, have pressures set right etc...

BTW - Biggest sand performance factor I've seen on same spec vehicles was tyre BRAND & Model... Where one vehicle went with no issues another struggled... Had a particular model tyre that was useless on sand - totally useless - an A/T style from Bridgestone - On a D1... But worked great on Landcruisers.... Swapped the tyres for a set of BFG A/Ts and it ate sand tracks for breakfast....

I did Fraser a couple of years ago in my D2a on 255/55/18's. Dropped them to 16psi and no problems.

[mattg]

I am doing what you are thinking about 18s with great Continental HTs for 500 to 1500km that I do during the week then once or twice a month I take them off an fit some beasty 265/75/16s that are down to 6 to 8mm Good year wrangler MTR these are crazy good on the really soft sand around Port Macquarie. I don't think new MTRs would be as good, just think they dig to big a whole.

These are bigger then Standard and put the speedo out, against the GPS 102 on the speedo is 110 on GPS.

I have ripped off the inner guard this wouldn't be a problem with a 2 inch lift.

Have fun on Fraser, looking forward to doing this myself.

last weekend I nearly got stuck on a beach exit that was chopped up real bad and had to turn 45 deg in the middle. Next time i took pressures down to 15 in the back and 20 in the front to make sure I didn't roll off a rim. Worked a treat and just powered through.

Don't go for New Muddies for sand work. High profile HTs would probably be the pick.

Hey Tombie what pressures are you using off road? I have 18,s too and am very new to the idea of 55 series tyres on a 4x4.

[chuck]

The alloys on the D2a country Version are 16 x 8 rather then the standard 16 x 7.

If you wanted to keep 18's you could go up one size with no problem.
General Grabber have released a new AT in 255 x 60 x 18.
The tyre is supposed to perform very well and is getting good reports in the D3/4 section.
They are also reasonable priced at under $300.00 fitted & balanced.

You can also get bigger rubber in 18's ie 275 x 65 x 18 or 275 x 70 x 18 but you will need to have a good lift to fit these.
These will have almost as much sidewall as a 265 x 75 x 16.

I run 255/70R18's on my D2. These equates to around 32". The standard tyres are only 29"'s. Requires at least a 2" lift and there is some minor rubbing.

[bidds]

I'm in a D2a with 18"; running Nitto Terra Grappler AT in the 255/55R18 size. Done all the soft stuff at Stockton with zero drama's. Aired them down to 15 psi and kept speed below 40km/hr (most of the time anyway). Also used 255/55R18 Yokohama Advan ST's the same way and they went well too, a little less 'paddle effect' in the really soft stuff but a bit more speed cures all.

I was quite apprehensive about the 55 series tyres at first but will take them anywhere now. They're much quicker to air up and down too!

cheers
