What the heck is this on my car?
Michelin pilot SX. It's got the MXX3 tread pattern so that is what I thought I had.

Not XGTs
Not MXX3s
Not pilot sports

What is this stuff?

Roy, my understanding is MXX3s on earlier Viper's, although it is a Pilot SX, look elsewhere on the sidewall and you'll see the MXX3 markings, Pilot Sports took over as OEM around 2000??, and are hard to find the MXX3s new, not many around.......hope this helps the confusion. My MXX3s original from 1997 squeal on the 3 to 4th shift on full throttle, think it's time for some Kumhos!!!
