Does anyone know what size wheels and tyres you can safely use with and R32 GTR. Better yet, what is the recommended size, offset and tyre size for and r32 GTR?

17 x9 is about the max,but dont know the offset.
go to www.takakaira.com and check to wheel offsets there under alloy wheels

I have 18x9's on mine. But I also have HKS coil overs. That way they don't bottom out and rub. They will rub at low speeds on very tight u-turns, But only a little.

Hope that helps,
Robb
