Researching for a purchase, and it seems alot of folks drop rim size to 17". Why is that? Also which are the stickiest tires. I'm sure the answer to that is subjective. Curious what your opinions are.
by dropping the rim size to 17 inch you can gain sidewall width which helps absorb the shock to the tire when you launch the car. i also like the added effective gear ratio. with 275 40 17's on the rear my car goes through the traps at peak rpms.
