These tires are on a '79 rx7, car has stiffer springs and has been lowered. Was a bit concerned about ride quality and noise levels after reading some comments about this tire being noisy. Both concerns, for me , were un-founded as tires have a good ride and I have not noticed them being noisy. Hi-perf tires are a bit noisier than passenger car tires, but is not an issue with these. This car is not an everyday driver, has been modified quite a bit, and these tires are even better than I had hoped. They stick VERY well, have a more than acceptable ride and low noise level. What more could you ask for in a hi-perf tire?
