I've got a 2004 Crossfire that needs new tires. The tires currently on the car, are the original tires and are dry rot and cracked.

Just some background, I'm a college student, that drives about 3 miles back and forth to school/work and I've put about 6k miles on the car this year. It currently only has around 28k. I don't do any kind of racing/track stuff, so performance isn't really a concern. I live in the central valley of California, so I don't get hardly any rain, just 100+ heat in the summer. I'm just looking to get some cheap tires that I can put on the car and will be safe while I drive, with maybe the occasional 200 mile trip down to San Diego every few months.

The quote I got from the shop is for these.

They are the standard 225/40ZR18XL for the front and 255/35ZR19XL in the rear. For the two fronts, they are $80 each, and the rears are $97 each. With the road force wheel balance/weights/disposal fee, the shop quoted $482, which is extremely reasonable considering the Chrysler dealership wanted $1600 to install a new set of the originals.

Are these a decent tire that will last me a few thousand miles? Does anyone have any recommendations for a sub-$500 set of tires that I could put on these? Or one that isn't too much more than that? Any help is greatly appreciated.
