 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.
