    I love them. I had a tire shop install them when they put my new wheels and tires on. I gave them the instructions and some thread sealant to use. No problems. They seem to cut the brake dust down.

    How big are the rims holding your 315s?

    Maybe that's why I feel like I have more low end torque

    I think 11.5 inches, but I am not sure. They might have that listed on the Merrick Motorsports website.
