Call Discount tire direct and they will give you good ideas and selection. Others like Tirerack.com and
4Wheelonline.com usually patch prices and sometimes good deals so you may want to check them too. I recently saw $143 for set of 4 on Goodyear silentarmor, close to $110 each for Firestone destination AT general grabber AT2 which are quiet tires for on road. Kumho road ventures are good ones too and cheaper.
