Strike 1: I called them for two new 13″ trailer tires for my glider trailer and was quoted $ 59.95 + tax mounted plus $ 10/tire for balancing! This is the 1st time a Big O store has ever charged me for balancing!!! Strike 2: The bill came to $ 177 and change! They tried to «slip me a mickey» for several extra charges(valve stems, disposal, warranty, etc!!). Finally, after noting I called them, they settled for $ 143 and change! Strike 3: The next day I decided to check the tire pressure with a professional quality«steam gauge» pressure device. Tires were rated for 50 lbs cold. One tire was reading 68 lbs and the other at 32 lbs! I had a mechanic check my work. Same thing! I was told at Big O the lug bolts were tightened to 100 lbs torque. After the tire pressure errors by Big O, I knew I should check the lug bolts. Well two strong men both working together could not use a standard 4 armed lug wrench to break them loose. We had to revert to a breaker bar with a 5′ section of pipe to break it loose to a manageable torque. The only thing good I can say is that the staff were nice and friendly. But in the end, their work was shoddy and poor quality. Luckily I loosened the bolts enough that if I do have a flat I will not be stuck in BF Egypt with no way to get them off! Good luck if you have to go there!
