I bought 4 new Firestone tires plus an alignment which cost me over $600 from Tires Plus in Zephyrhills, Fl.
I took a 2000 mile trip right after the purchase and it was the worse ride ever. Car started to shimmy around 55 mph. The navigator wouldn't stay on the dash.
When I returned to Zephyrhills, went back to Tire Plus and was told that 3 tires out of 4 were out of balance. How can that be?
Their comment was "Sorry about that". They did rebalance them but haven't been out on highway to check it out since.
