Default Kumho MX and Goodyear Eagle F1 GSD3 will fit in that size.

Don't even have to roll much unless you plan on slamming or run low rates. Tires will roll what they need to for the most part No issues on the rear.

IMHO, you will need spacers. ET37 here, and I have less than 5mm space.

Thanx! Do you think a 5mm spacer will be enough?

Default the lowdown...

run a 10mm spacer. with unrolled fenders, my 35mm offset wheels sit perfectly equidistant from the fender and the upright in the front. with my rolled front fenders now, there is a little more space by the fender than the upright, but it doesnt matter. use a 35mm offset either way, and run tires with a section width of less than 9.8" or so and it shouldnt rub at all. you also won't need to roll your rear fenders, just the fronts.

Default you run 245 Dunlop SP's with et 35 offset?

If I remember correctly you were running Dunlop SP(which run wide) at Poconos.with your math then on my et 40 wheels I could run 5mm spacers and can run Dunlops in 245?I have been thinking about going with a wider tire but want to make sure.

Default 235/40/18 (measures about the same as average 255/35/18 street tires)

they are now being discontinued. i havent experimented with other offsets yet (35-38 is definitely the hot spot), but 35mm offset with 10.2" wide tires worked. just look at the specs of any race tire, and if the section width is 10.2 or lower it will definitely work. Bauer is running dunlop 255's on a 38mm offset (11" wide tire!!!!!) without problems it seems, so i think for next season i'll be going to something wider as well.
