40 or 45 series and what is a good width on sprint springs might go lower.

215/45 is perfect for our cars. that's what i roll. wider may rub and lower profile will look goofy(unless you got 18') and won't ride as soft.

I have 225/45/17's and they dont rub at all.... but I dont have aftermarket springs, My new rollers actually feel they ride smoother than my old 14's....

Klipz is right, 215/45/17 are perfect on our lowered cars. I had 235/45/17 on my car for a while and it rubbed with every bump. The 235s hugged the road like a tank but it slowed my car down alot and gave me terrible MPGs. I then switched to 215/40/17 and i guess the lightened load made my car go faster. They did look goofy, cuz the whole set up look like i was rolling on some stock 14s doughnuts. Now I'm back to the 215/45.
