If you want something different and less expensive, look into the 3RZ-FE from Toyota trucks, its a 2.7L 4 Cyl that loves the boost.

Speaking from experience, I'd stay away from RE92's, they're all around craptacular tire, unless you're looking to save a bit on gas. But then the price per tire compared to some Khumo's kinda kills that.
Agreed, wheel manufacturers design the wheel to fit a wider range of applications, which means that the wheel doesn't sit on the hub as its supposed to, but sits on the wheel studs. Hubcentric rings are cheap.
