Purchased these tires for my Shelby GT500 because most tire brands want $300-500 PER TIRE for this car, but Rydanz had these UHP, high speed rated, 103Y, good looking tires for $360 FOR A WHOLE SET OF 4......mounted up, balanced easy, have had them up to 130mph......smooth ride, good stable handling, MUCH better ride and traction than the original Goodyears....ALL reviews of these Rydanz tires have been positive.....WHAT A FIND! Only negative I could find was some people afraid of "Chinese tires", well, go look on YouTube at Chinese tire factories and you will see most of them are newer, cleaner, higher-tech than other tire factories around the world! People used to warn me about my "Japanese" tires, Yokohama, Sumitomo, Nitto, etc., but now you see they are top-line, well respected tires.....so, I think I just found the newest top-line tire at bargain, introductory pricing. Mine are 275/45R18 all the way around instead of staggered sizes from the factory, so now I can even rotate the tires for even longer life....added plus!
