Why not use 17 or 18" wheels? is the tire selection worse or are the 16s just what you have and are sticking with them? i also have 16x8 wheels and have been thinking of swapping them over to 17s or 18s in hopes of finding more available tires.



Because in the world of race tires, it is a whole 'nuther animal in price, performance, and availability than what you may be familiar with in street tires. Heck, in the race tire world, 15" are still competitive rubber. There is also that nagging little issue of rule compliance that you need to keep in mind.
