I've been data logging the Challenger for my tuner and have put the 555Rs to the test in 30 degree weather several times. Corner like a normal tire as well.

I make it a point not to drive either car in the rain, but have been caught in the Challenger coming home from ChallengerFest a time or two. No issues with the 555R and they even offer a non "R" version to run up front that has the same tread pattern so they match. Would be a fantastic tire for this solution.

Bottom line, modern tire tech has allowed DRs to come a LONG way in the past few years so much so that tread wear is about the only down side, but looks like the "summer only" GY Eagle F1s don't last very long either. I'm at 5,000 miles or a little over on my 555R DRs on the Challenger with LOTS of WOT pounding and have 25% or so tread left. I've read folks get 8,000 - 10,000 miles from the GY Eagle F1s.

There's a big difference in a DR and a sicky summer only tire like the GYs or Pilot Sports, etc... The soft sidewall is the biggest safety concern next to the ability to actually deal with standing water. Handling a wet surface is one thing but displacing a standing puddle with a couple of thin grooves is another entirely. If it wasn't so then we would have seen them on cars like the Hellcat to begin with.

Your 555Rs are also a compromise, not quite as sticky as other DRs but much better at dealing with water due to their tread. There is no tire that is perfect granted, but too many safety issues to sell a DR on factory car. Don't forget we live in an age where everyone has to have ABS, STM, TCS, and before too long crash avoidance. Had we had DRs in the 60's and 70's....someone would have sold them with it.
