MTC may not always have the absolute best prices, but they do have the best tech's and service. My last set of tires was purchased at a Yamaha dealer because they had a great sale price on PR4's. I had serious wheel balance issues that took two additional trips and 3 hours of waiting to resolve. Prior to that, I've always had MTC install my tires and NEVER had any issues. I feel like a schmuck for trying save a few $ and going elsewhere - in the end it cost me time and money.
When these PR4's are worn out, I'll be back to MTC for another set. Love MTC (also really, really like the PR4's on my FJR).
