Ah yep, I need 5 new tyres anyway before venturing out as my spare is an original 255 and everything on the car is 265 atm....

Basically i'm looking for any excuse to put bigger/AT tyres on i think!

You'll notice it. It will dull down the vehicle a noticeable amount going to the 285...

Hi Tombie, by dull down do you mean with acceleration because of the larger diameter tyre?

OK let me add the last 8600km of experience to this discussion. As you will know we have D697's on GOE rims and 265/60's. So over the last eight weeks we have towed the Ulti up the main drag to Darwin doing several interesting dirt tracks along the way including the Finke. Refer my Follow Me section for the details.

Now in Kununurra for the second time as we lap the Kimberley. Done all dirt roads so far including; Drysdale, Mitchell Falls, Gibb River West to East, ELQ, Nt Hart and Mornington Wilderness Sanctuary amongst other places. All towing the Ulti and the D4 reasonably heavily loaded

Pressures on bitumen have been 38F, 48R and 38 in the camper. Off bitumen have been 24F, 28R and 24 in the camper.

Condition of tyres is excellent given the rocks, stoney roads, corrugations, low range rock crawling and towing they have done. Estimated at 20% worn with mild chipping on the rears which have been doing all the really hard work.

No hint of any problems and the car had a full F&R alignment and balance at Solitaire in Adelaide prior to departure and no sign of any issues relating to balance and/or alignment

Yes Aaron.I had the same issue in my D2.
I parked next to a 200 Series today,it had 285/60x18 highway tyres.They are a big tyre compared to my 265/60 tyres.

Yep.. Off the line, up hills, sand and towing.

And whether or not you like it it will impact TC offroad as the leverage of the larger radius will impact response (reaction over distance) and wear

And not sure where you are but if you ever intend to use chains they won't fit without doing major damage.

Tombie did you put a second set of D697's on when you changed over your tyres?
