Hi everyone, My factory stock Michelin Primacy tires will need to be replaced in the next 5,000-10,000 miles and I was wondering if I could get feedback and opinions from forum members on good tires. I've searched this forum and have also done a lot of research online, and I thought I should start my own thread because I'm looking for some specific feedback. I really do appreciate everyone's help and thank all of you wonderful people in advance for helping me out. First, let me say that I like a comfortable ride. However, sometimes I wonder what I'm giving up in terms of performance for that comfortable ride, and whether there is a much better performing tire that will still give me quiet comfort. The Primacy is a grand touring tire, but I'm leaning towards either UHP all-season or max performance summer tires. I live in the Phoenix area, so need to cope with torrential rain a handful of times each year. My cars have seen light snow maybe once or twice in the last 10 years. My dissatisfaction with the Primacies stems from the fact that they tramline like crazy on certain sections of freeway, and they are not particularly forgiving of road imperfections. The ride feels a little rough and they are also quite noisy on some of the rougher pavement around town. Expansion joints and cracks in the road feel much more pronounced than they should - the Primacies seem to do a good job of transmitting all of that feedback into the cabin. I drive a 2013 P85 on 19" factory wheels. Here are the tires that I'm considering, I'd love some feedback from other members on whether they like or dislike the following: Michelin Pilot Sport 3 - Max performance summer Michelin Pilot Sport A/S 3 - UHP all-season Michelin Pilot Super Sport - Max performance summer, but only available in 255 width (stock is 245) BFgoodrich G-Force Comp-2 A/S - Max performance summer Dunlop Signature HP - UHP all-season Bridgestone Potenza S-04 Pole Position - Max performance summer The tire that has the best reviews and feedback seems to be the Michelin Pilot Super Sport, but it's only available in a 255/45R19 versus the factory spec of 245/45R19. Would there be any down sides to installing the 255 variety? Can this tire be installed on the stock 19" wheels, and can anyone with this setup provide feedback on whether there is rubbing on the wheel wells? I suspect the answer is yes, but I'm hoping maybe that's not the case. My second choice would be the Michelin Pilot Sport 3, but it's not a LRR (low rolling resistance) tire. Will I sacrifice a lot of range with a non-LRR tire? The Michelin Pilot Sport A/S 3 is pretty close to the PS3 in performance, but it's also not LRR. Tire Rack gave good reviews for noise and ride quality to the Dunlop Signature HP and said the BFGoodrich G-Force Comp-2 A/S offers excellent dry and wet traction. The G-Force has a much more aggressive and directional tread pattern which looks impressive, but wondering if that translates into any real-world advantages? Seems like there is much more rubber in contact with the road in the G-Force than in the others. It's so difficult trying to make sense of all the different ratings, sizes, and tire types, especially when I don't really have experience with anything but the Michelin Primacies. Whatever I choose I will have to live with for many thousands of miles, so I'm trying to avoid making an expensive mistake. Would I be sacrificing much comfort and noise isolation by going with a summer tire? Would summer tires perform well year-round here in Phoenix, even if we get frost maybe one week out of the year? Do summer tires cause much reduction in range, assuming one that is not LRR? I've spent days researching, reading reviews, and watching videos online. The process has left me quite confused as to what is best for someone in my situation. Help!
