Go to discount tire, ask them what they recommend for a quiet, comfortable ride. That's it!
The guys at Discount Tire have never steered me wrong, and I've bought cheap tires all the way up to performance Michelins. I've always known what to expect and gotten what I've paid for.
I know it sounds like I work there... I don't - I just have been really impressed and I've probably bought 5 or 6 sets of tires there by now.
