shopping was fast and easy

Finding the part was super easy and simple. The only issue I really had was the delay in the shipping. I paid extra for faster shipping and it still took over a week to get to me. When I tried contacting them through the chat I never got any feedback after asking questions just a "let me check that for you" then chat ended. I finally decided to email and then I got a reply basically saying the same thing. Correct part did wind up showing up without tracking update(kept showing sent to warehouse).

VERY EASY TO ORDER AND CHECK OUT.

Good prices and the tires were fresh. No complaints or issues.

THmotorsports had what I needed at a good price and they shipped right away.
