If you are considering getting dedicated snows for your GM SUV, get ready for an exceptional buy! I have a set of practically new (750 miles) Firestone Winterforce UV tires mounted on OEM Chevy Trailblazer rims. Tires are P235/65R17 and the rim offset will fit the EXT models. The 6-lug rims are discolored from road salt, etc. but are solid, straight and true. I'm basically giving them away at this price. This setup will also fit the Olds Bravada.
