Been running the original Nitto 555s for some years now and very pleased with both the performance and price. Fresh on the Cobra today, new Gen 2 315s out back and 275s on the front then out for a drive we went. Can honestly say so far I'm pretty darn impressed, while I really liked the Gen 1 these are all that and then some. Noticeable reduction in harshness over even sharp bumps plus appreciable difference in steering feedback as you go into a corner. Not sure how they'll stack up traction wise, still pretty cool out there but so far so good. Thanks again to Fast Ed at Parkway Ford for hooking me up.
