I need a set of tires for my car. I was recently quoted $850 for a set with 30k warranty and $892 for a set with a 80k warranty. (prices are mounted and balanced). Wondering if someone here did tires and would have a better price. Tires are going on an AWD sedan. Size is 235/55/18. Dont need high end tires, but I dont want tires that get noisy/sloppy at 20k either.
