HELP 20'' tires, what size

[copestang]

i'm getting 20" wheels (20x10 20x8.5) for my 08 gt but don't what size tires it seem to a long range, it my everyday car so i want the best ride and look, i plan to lower(don't know yet)

I would run a 265 width on the front at at least a 285 on the rear, as far as sidewall size I'd find a tire calculator and see what size sidewall would put you closest to stock for speedometer purposes.

For 20x8.5, american muscle says 255/35 and for 20x10 285/30

I would do a 265 on an 8.5 wide tire, if a 255/35 works then a 265/35 is just fine as well.

A 255 on an 8 wide gives some rim lip protection so a 265 on an 8.5 wide will help as well, you dont want to curb those nice wheels do you? Plus you always want a nice flat sidewall on your rim or it looks all stretched and bad.
