Tyre and Wheel Gurus...Help needed on R230 SL350 Choice

[derin100]

So just like another member being driven crazy by choice in another thread, I have a similar but slightly different dilemna/question.

My SL350 is currently fitted with 255 40 18 on 8.5J rims at the front.

On the rear it has 285 35 18 on 9.5J rims.

I need to replace all four tyres.

The MB Handbook lists on option for the SL350 as having a matched set-up option (as opposed to the staggered option above) of 255 40 18 all-round. BUT it shows that set-up as being on 8.5J rims at the rear.

Would it still be possible for me to have this matched set-up with 255 40 18 all round, even though I have 9.5J rear rims? Or would there be a problem/issue with putting those tyres on to those rims?

Many thanks in advance!

245 to 275 can be fitted to a 9J rim.
It seems your current 285 x 35 x 18 on a 9J rim, is excessive???

Thanks!

The 285 35 18 is actually factory spec. It's a 9.5J rim.

But I'm guessing from what you say, a 255 40 could go on to a 9.5J ?

Thanks
