When trying to purchase four trailer tires, the web site was non functional. I repeatedly entered the info, and the system would not accept the order. I phoned and a pleasant but unknowlegeable person said they were having issues. I tried repeatedly and ended up having to place the order by phone. When on line, they solicited my phone number in return for a discount code, then wouldn't accept the code for the purchase which resulted in a bunch of texts and spam calls. Depsite having received the tires, I received repeated texts asking me to complete my order on line. When I received the tires they were three years old. I contacted the manufacturer as I was concerned about utilizing them due to degredation. They informed me that the warrantly was six years from the manufacture date, so I would only have three years left on the warranty. The manufacturer had never heard of Simple Tire and weren't sure how they got the tires. I phoned and was given an excuse about their inventory management approach. I asked to speak to a support specialist, none answered and I unable to leave a message. I received an e-mail after hours, I responded with the details and never hear back so I couldn't even exchange the tires. I have purchased a lot of tires in my life, have never had an experience like this one. User's recommendation: Just don't.
