Diameter puzzle ????
Mouse:
Hi there :)
I'm in need of 2 new tyre,s for my 200tdi and at the moment am running 235/85x16 looking to go wider i.e 267/75x16.
I know that there is a differnce in diamater but will this cause any problums with the transmission because of running differnt diamater tyres front and rear ???, my thinking is that the front and rear axles will be turning at differnt speeds.
Also can anyone suggest a supplyer who has a good selection of 265/75x16 mud pattern tyres (preff remolds because of price).
Thanks
Mouse.

265/75s and 235/85s are almost exactly the same diameter, so although normally you wouldn't want to run different tyres at front and rear, in this case I don't think it'll cause you any problems.
In theory the 265/75s will have 1/3" smaller circumference (which equates to about 1 revolution/mile difference) but that could easily be absorbed by manufacturing variations.
--- Code: ---Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
265/75-16 7.8in 15.8in 31.6in 99.4in 637 0.0%
235/85-16 7.9in 15.9in 31.7in 99.7in 636 0.2%
--- End code ---

Cheers mate :)
But can you tell me what 1/3" means as i'm having a bit of a thicky day.
Thanks
Mouse.
