well, I just got some 33 kevlar wrangler's (285's) on rubicon wheels off craigslist. And so far I'm extremely satisfies with how well my little 4 banger is doing with them. I don't see 5th until like 80, but then again the gears are shifted so bad I don't need it. I used to drive at 3k rpm at 70 in 5th. Now I'm turning the same rpm in 4th.
