Tire sizing question - New Wheels on the way

[Jordan Adams]

I just ordered a set of Ambit FC20's in 20x9 +25 (front) and 20x10.5 +45 (rear). I was planning on getting Firestone Firehawk Indy 500 tires. I should be able to run a 275/35/20 and was curious what size to run in the back. The only size available in the Indy 500 is a 305/35/20. Would that fit ok? It would probably be better to run a 30 series tire, but its not made in that size.

If you think I should run a 30 series, what tire do you reccomend?

Thanks all

Yes that would fit fine.

If you're on springs a 305/35/20 would work with no problem.
