which tire size should I go with on 20" wheels?

Tufosi · 02-07-2013, 12:30 PM

I did use the search button but couldn't find this information.

Im thinking of getting a set of 20" BBS LM-Rs (Ericson setup) which are 20x9 et-8 and 20x10 et-18. The car will also be lower with springs probably RD sports springs or Swift Spec-R Sports springs.

What tire size do you guys recomd me using? I know that wheel setup is a bit more aggressive then normal so I want to make sure I get the correct tire size.

I think 245-30-20 and 295-25-20 is ideal. Depending on tire brand / model I rub on the front with 255-30-20s but I'm slammed all the way on kw v3s. I also ran 275-30-20, 285-30-20 on different wheels and I've seen other members with 305-25-20s in the rear.

Do a search for the Ericsson setup on here and you should find plenty of tire info.
