Benefit of running thicker rears??

Just an idea, but what would the benefit be to running 35's on the rear tires as opposed to the factory 30's? I'm thinking better ride comfort. You guys think rubbing would be an issue?

With stock width on a non lower car it shouldn't be a problem. However you will effectively decrease the rear end gear ratio resulting in a small loss of accelation. It could impact the balance of the car as well as the alignment. You'd be better off looking for some stock size tires that have a softer ride. Check with Tire Rack.

+1 and your speedometer will be off too.
