I have been Greg's customer for 2 years now, and have been happy until just recently. I bought FOUR tires from Greg's on August 3, 2018, and on August 18, 2018, my TPMS warning light came on. Before I could get to a gas station with a working compressor, my tire went PANCAKE flat. As it was Saturday, and I didn't really have any place to be, I decided to wait until Monday morning, and take it back to Greg's, as I was still within the 30 warranty for used tires. I left home with plenty of time to arrive to Greg's right at 8AM, so I could hopefully get my tire repaired, or otherwise have my warranty honored, only to find that they are CLOSED until September 17, "for vacation." I live a fair distance from my place of employment, and also had plans to travel this upcoming weekend, neither of which will be safe or advisable with a donut on my car. I am hopeful that Greg's will honor THEIR warranty, as my tire failed barely 15 days into a 30 day warranty; I came right back to the shop, but THEY are closed until well after my warranty will have expired. I will be more than happy to change this rating to a more positive one, should they honor the warranty on my tire, since it will be their fault that I am unable to return until after the warranty period.
