Big O Tires stores in Southern California are currently running a Buy 2 Get 2 Free Sale through Monday, Sept. 11th on Sumitomo HTR A/S P02 and Aspen Touring A/S passenger/performance tires and Mesa A/P2 SUV/truck tires.
The offer is a package that includes a one-year alignment and their tire protection plan (free tire rotations, free balancing, free flat tire repairs, roadside assistance, road hazard warranty).
I was quoted $350+tax for a set of 50,000 mile rated Aspen Touring tires for my Prius They also had a 100,000 mile rated Sumitomo Tour Plus tire that they were including on the Buy 2 Get 2 Free offer and those came to $452+tax (this includes the one-year alignment and tire protection plan).
If you pay with your Big O Tires credit card, you can also save an additional $25 or $50, plus they have 6/12 months interest free financing (purchases $250-$499 = $25 rebate; $500+ = $50 rebate).
