Thread: Tyres 285 x 75 x 16 on +8 offset rims

The standard alloys are 7" They are the Standard alloys that came on it from factory, which im led to believe are +33 offset (?)

They rub annoyingly on full lock, worse in one direction than the other, this can be fixed by adjusting the steering stops, but ive never bothered. I only encounter it at slow speeds in carparks or backing out of my driveway.


The steelies with 31's were 8" with -25 offset.

Hi Pete

I have just fitted 265/75/16 cooper stt to my disco with 16x7 alloys. They sit just inside the guard and I am thinking of changing to a 16x7 steely with a +20 off set to improve the turning but still keep them inside the guard and not needing flares etc.

I had to adjust the steering stoppers, the driver side further for some reason????

Not sure if that helps you but you are welcome to have a look if you like.

Cheers mate

Hi Mark thanks for that, I have 2 sets of flares (flatdog) here as I brought 2 sets - 1 X 3 inch and one 2 inch. I am fitting the 3 inch set to mine and will sell the other set as the cost of freight was the same for 2 sets. I am buying 5 x 16X8 with a +8 offset as that is the max legally (50mm), and I have worked out that I can fit 285/75/16 and they should not rub (fingers crossed ). The drivers side on the discos are all like that for some reason, they must hit somewhere before the other side? What year is yours as the series 2 changed. I may take you up on your offer to have a look.
With yours I have a calculator and it puts your 265/75/16 X 7 inch rims with a +20 offset it would be 17mm closer to the radius arm over standard 205/80 16 X 7 +33. I have worked out from all the posts I have that 20mm clears 245/75 16 X 7 +33 on the 95 face lift and on, and yours will stick out a further 13mm towards your guards than they do now with the new +20.
Thanks for your help.

Ok so I have compiled a list that might help some. It shows the offset from standard. The reason I have used the +8 rims is because that is the maximum legal 50mm track increase allowed, in most states.

28.9 inch or 205/80,16 X7 +33 This is the steel Rim and tyre combination used for the comparisons below and is also the standard factory fitted rim

29.0 inch or 235/70 16 X7 +33 alloy rims, (factory fitted rims) and it is 15mm closer to the radius arm than the 28.9 205/80,16 X7 +33
Standard Track width 1486mm
Track width with -25mm offset 1600mm
Track width with +8mm offset 1586mm
16 X 7 +33 (Factory steel rims used as control)
31.6 inch or 267/75/16 X7 30mm closer to the radius arm
31.2 inch or 275/70/16 X7 35mm closer to the radius arm
30.5 inch or 245/75/16 X7 20mm closer to the radius arm, seems to rubs on the 95 pre face lift models, seems to be fine from the 95 face lift on.
31.7 inch or 235/85/16 X7 15mm closer to the radius arm and does not rub


New steel 16 X 8 +8mm rims
32.8 inch or 285/75/16 X8 15mm closer to the radius arm
33.1 inch or 255/85/16 x8 The same as factory steel rim
30.6 inch or 265/70/16 X8 5mm closer to the radius arm
30.6 inch or 265/75/16 X8 5mm closer to the radius arm
31.7 inch or 235/85/16 X8 3.0mm Further away from the radius arm


Cheers, Peter

I'm not sure on those calculations Pete. Mine is a Feb 99 so last of the D1's.

I have factory 16x7 alloys with a +30 offset. Regardless of the tyres fitted, if I go to a 16x7 rim with a +20 offset, that will move the rims outwards by 10mm... Giving more clearance to the front radius arms, so that should allow me to wind the steering stops back in somewhat. Is that right, it's doin my head in all this math ?????? Haha
