couldn't really find what i needed using the search....so here goes.

I have vossens cv1s, rear tire is 285/30/20 and 245/35/20 fronts....

Whats the standard tire pressure needed? i know on the sidewall the pressure is on there but i figured if you go larger size wheels that you might need more pressure...

Larger size wheels than what?

There's supposably a formula out there I never did find and just went with the following two recommendations and my butt. Generally for performance one recommendation was 10% of max tire pressure ...45psi for me. A good starting point is 25% of max 37.5psi I rounded up to 38psi and enjoyed the ride quality here better.

its just i'm thinking because the rear tires are much bigger then my stock tires that they need more pressure for some reason....so i'll do about 38 all around

Yea if you look at the stock's 18" is 33psi, 19" 35psi so 20" at 38psi seems about right. Could even go a bit higher for low profile protection.
