Shady business practices. Sent my wife in on Friday with a nail in her tire. Had already taken the tire off prior to going to Big O to inspect it for the leak. Big O employee tried telling her the nail was next to a previous patch and would have to replace the whole tire. They claimed the patches were too close. And of course since the front tires are at 20k miles they recommend replacing both. Got the call for a 180 dollar bill. I already knew the first patch was on the opposite side after looking for the leak this time. Send wife to Discount Tire. In and out 30 minutes with a free tire repair, no BS, and a coupon for tires when she actually needs them.
