Thread: 255/85r16: what rim?

Yeh I would have thought so too. Maybe the maxxis isn't as wide as the KM2?

the more you know!

From what I have read they may rub on spring perches, and may rub at full lock (so adjust the stops). Yay for hand built vehicles!

Mine worked fine but the Perenties are taller.

EDIT: KM2s are on my Perentie.

I've had a set of 255/85 KM2 on the front, no rubbing until I adjusted the steering stops for maximum lock with the 235/85 set to help with the turning circle. (just not touching). The 255 rub a bit now, but I don't hold it at maximum lock.

I've had both the Maxis and the KM2s on the rear with no rubbing to date that I could see at least.

Just an update for anyone interested...

I'm getting a set of disco 1 steel rims modified by 25mm, which will give me approx +8mm offset to run the KM2 255/85r16s. Things I have learnt along the way:
- Maxxis bighorns officially are no longer made in that size. Despite what their outdated website states
- Dick Cepek now do the Extreme Country MT in that size
- I wanted to keep things legal, so confirmed with vicroads that the maximum increase in track width is 25mm, and maximum increase in tyre diameter is 50mm (255s are 34mm larger than 235s). I have sawtooth alloys so going from +20mm offset to +8mm offset is a 24mm increase in track width...if my maths is correct. So I'm guessing that technically 0 offset rims would require engineer approval?

Seems a waste of money to get them modified when they will fit without modification!?

Or have we been through this already? I forget...

I can tell you that 265x75 x16 on Disco 1 Rims do rub on the side of the spring hanger when articulated ! I thought by buying that size tyre was saving a few $$ . Until I found the wear marks on the rear , So then It cost me a set of 20mm offset rims . Now I looking back pleased that I did . They sit inside of the wheel flares , and It handles fine . I don't think wheel spacers are legal in Oz . I'm sure that someone will correct me if I'm wrong !!.. Jim

Hi all,

I thought I'd just sneak in on this thread, rather than start a new one.

I've read plenty of other threads, via search, about the 255/85R16's. I am considering this size for my next set of tyres.

By the time my current set (265/75R16 Hankook Dynapro MT) wear out, the vehicle will be out of warranty. It expires April 2017.

I know that fitting the 255's is currently an issue with LR regarding warranty. Can someone elaborate a little for me? Is the thinking that the larger rolling diameter will place additional stress on driveline components?

Further, I'd be very keen to hear from anyone using 255's long term to see if they have actually resulted in any driveline issues or any other mechanical problems.

I seem to have read a lot of very positive posts about the 255 (remote availability aside) but other than a few warnings about voiding warranty, I've not seen anything more specific about exactly what damage LR fear may be caused by this fitment.

Is anyone able (willing) to shed some light?
