Still waiting for first correct numbers.. i have 10x18 et 40 back this summer with 255/35

You could go 275/35R18 on the 10" rim, but you would want to match the tire diameter the best you can so you would want 235/40R18 at the front.

Yes i know but with 10x18 et 40 that tire is too wide... 225 and 255 match optimally when 40 and 35 profiles

Too wide for what?



Tyre Size for Rim Size/Width Calculator - What's the best tyre size for my rim?

Sorry my english.. i meant that with 275 et 40 would scrub my arc/fender(?). With 255 i can get away not touching these arches/fenders...

That's interesting. A 10" wide with with a 40 offset is supposed to fit perfect even with a 275 tire.
