Great tires

  • Great tires
So far they do great, they ride smooth they have great tread, I've even accidentally got them in mud and they did really well

  • Quiet and sure footed
We've had these close to a year and about 18k miles on them. They're still quiet and smooth. I mounted them myself and had no issues with excess balance weight required.
