wheel bolt pattern

[omegavx]

Ok, I'm looking to buy new wheel's for 2001 vx online. But, I can't seem to figure out exactly what bolt pattern I need. It looks like there are two choices 6/135 or 6/5.5. I'm guessing its 6/5.5, but can anyone confirm this?

Also, for those with 20 inch wheels, at what size tire did you actually need to perform surgery on your body cladding? Is there a certain size tire/wheel you shouldn't go over to prevent this?

Thanks in advance
