Traded truck just before X-mas and the new used one came with "Trail Mark" Radial APR's on it. They were brade new and I expect something the dealer could put on cheap. Thing is, after a couple thousand miles, I'm loving them. They are better than any Firestone or Bridgestone I had recently. Great in snow and show no damage from the gravel I travel on a daily basis. I'm thinking they must be a relatively hard compound. Anybody know who caries this brand?
