The ONLY two brands to buy are Michelin Pilot Sports 4S summer tires or Continental Extreme Contact Sport summer tires if you want a max traction moderate to hot weather street tire that will both hook and last a while. If you want an all-season the same two brands but in this case it would be the Michelin Pilot Sport All Season 4 tires or the Continental Extreme Contact DWS 06. The DWS in Continental stands for dry, wet, and snow. The Conti summer tires only have a D and W on them, no S. A buddy of mine ordered the Conti Extreme Contact Sports and ended up with the DWS 06 tires. He was super pissed and the tire place he got them from wouldn't return them as he got them at some discount on sale. Talk about someone that was super pissed and sad. I told him to make the best of it and mount the all-season Contis on the factory wheels and order a set of the summer tires for the aftermarket 3 piece Velgen wheels I sold him. Regardless, either brand in either configuration is leaps and bounds better than the absolute garbage Pirellis that come stock. I swear the Conti All Seasons were even MUCH better than the Pirelli ZERO Summer Performance factory tires on my 1st Hellcat which was an '18 standard body Hellcat if that tells you anything! Also the size to go with is the 315/35R20 if you have a widebody. They fill the wheel wells better, look better, and you get some serious added traction, particularly laterally. If you are just changing the rears you could go with a Nitto NT555RII drag radial in the factory size. Just speaking from what I have read on here, you will be much happier going with a square tire upgrade at all 4 corners in the slightly larger size.
