The high price of fuel made it necessary to downsize to smaller vehicles. After owning 3 other Sentras I bought a pair of loaded 06s. The aluminum wheels and Firehawk tires are junk. I have replaced 3 rims and 4 tires because they are so poorly made the won't stand up to midwestern highways. This isn't just an expense but a danger. I am looking into the possibility of a product liability suit.
Forget the low profile tires and put a decent rims on the vehicle.
