Thread: Another dumb wheel tyre question!

Oh and does the thinner wheel with larger tyre when off road and pressure lowered have better performance?

Like any number, my D2 runs 265 75 16 with a 50 mm lift. I do however have the 8" x 6 spoke Classic/P38 rims.
Main reason for responding is to say no rubbing, either on steering or articulation extremes.
Yes, the 265 75 are a "bit" over the 2 inch limit at about 31.7, and I think your 265 70 is good thinking.
I'll be doing the same when I retire (no pun intended) my existing Scorpions for the new ATR ineration - soon!
Thanks for the post

Thanks Gavin, assuming the offset is the same as mine at 51 (reputedly) or as noted here

Bolt pattern | Stud Pattern : LAND ROVER Bolt patterns

this lists it as H or high, who would have guessed, a general offset irrespective of wheel width. Wouldn't they modify the offset dependent on wheel width? I say this because even with the 255 width standard with the 8" this takes it closer to the rub points that many talk about.

I'm no wheel boffin and until now never had to worry about this stuff, but the last thing I want is rubbing.

Yes. ...the track of a narrower taller tyre lengthens more than it widens = more tread/less sidewall on the ground + less frontal resistance.

I also believe this applies on road with tyres at recommended pressures. (Many who want the racing car, wide tyre, low profile ‘look’ will no doubt disagree). IMO Wider is not necesssrily better on a 4x4 (unless you’re in the Arctic but then your sidewalls would be massive too ).

Scared to go there Zero's LOL This is more contentious than Labour v Liberal v Green, Richmond v Collingwood v Carlton, Land Rover v Nissan v Toyota v Jeep or Courtney Cox v Jennifer Anniston....

Was thinking more along the line of the difference in having a 265 70 on either an 8" rim against how it performs on 7", my mind can contort the image of these together but how does it impact

• initially on any rubbing issue and then
• performance out on the tracks

What pressures out on the tracks would one reasonably expect, would primarily be looking at the high country and then maybe up around HATTAH mid to late this year - the group i have traveled with just put theirs down to 25 psi but a much more experienced $WD said he wouldn't run above 18 psi

I run classic 6.5 inch wolf rims on my Defender. Not sure if D2’s can run 6.5’s? ...if not I’d go the 7inch. The tyre sidewalls will be more vertical.

I'm no expert but Disco 2's generally came with 7" rims until towards the end of the model, when 8" rims were available and carried over to the P38.

Don't forget that only half of the extra width is on the inside, and I've never heard of any significant rubbing on full lock, although I am aware that most with 8" rims will wind back the steering stops as far as they can.

Zero's the more vertical tyre wall would be the 8" I thought, as the wider 10" plus width of 10.43" would bulb out on the 7" more than the 8" - sure bulb out is a technical term used by RR as well as LR engineers. In my research to date, have not seen a 6.5 on either D1 or D2 but then I keep seeing new information all the time.

Gavin, would not LR when fitting the 8" which was definitely an option as shown on the tyre placard with 255 tyres, have themselves put the steering stops in appropriate position to allow for the extra width of tyre, this is where the original specs can show the turning circles for the 7" shod versus 8" being adjusted for the adjustment??? Again without the appropriate verification it is all just supposition I suppose. ohh ohhhhh oh to have the specification sheets!
