I could put on my 99 Chevy Tracker 4x4 It comes stock with 205/75-15 tires on 5-5.5 rims I want to know what the widest rims I could get and what size tires I would need to get. I'm thinking between 16-18 and probably 5.5-9 rims would fit? I like the Yokahama Paradas2 and was hoping I could find something that would work with those tires.

the largest wheel and tire combo I would recommend is a 17x8 with a 255/50-17 tire size

What would the offset be on the 17x8 and the 16x8 rim?
