Nothing is more important to your automotive safety than good tires. It never ceases to amaze me how nonchalant really smart people are about them. From simple stuff like tire pressures to balancing, wheel alignment and proper rotation - people just take their tires for granted.
If you care about your safety and want to save money, you should consider using a great tire store like Euro-Tire. An under inflated tire wastes gas and can fail, leaving you stranded or worse, in an accident (think Ford Explorer / Firestone). Improper alignment and wheel balancing will shorten the life of your tires and cost you money.
The people at Euro-Tire know tires, will educate you on what is the best for your personal needs. I have never been "over sold" or worse, "under sold" for any of my cars. They know everything about tire and suspension safety and will do everything possible to ensure that your car has the proper size and quality tire - period!
