I am new to the site have an 2003 Polo Green Sierra Denali with the 17" alum. rims. I was wondering if The factory 20" denali rims are ok with 275/55/20 tires to use on my truck. I was wondering if they would hit the rear wheel wells or they will be ok? Or if anyone has a used set for sale I would be interested! Also I just had the module and the motor replaced on my rear quadrasteer, it kept kicking out and giving me a fault in the dash, it was a 2500 dollar fix, anyone else have these problems?

Welcome to the site. No issues with the 275/55/20. Keep in mind the 20" replicas, they look pretty darn good (also may save some green). If you go with the same style as your 17" and like your center caps, keep them for your 20s.

I have been running 285/50/20's on my truck for nearly a year. I did remove them and put the all season tires back on during the winter months here as the tires on the wheels are not good in snow.

Enjoy your vehicle and have a nice day.
