6 bolt pattern (fits most GMC vehicles). 305/40R22 falkon tires. These rims have been on my truck for the last 2 1/2 summers, never on in winter. Minor nicks on a couple of the rims but nothing serious, they still look amazing. 2 new tires are needed but i am selling all 4 rims and all 4 tires. The black inserts are removeable. Only asking $1400 for everything.
