Just picked up my new F550 Dump Truck. I took the Generals off and put on some bigger skins. I have 4 Tires off the Rear - Continental General LMT450 22570R19.5 and 2 Continental General LMT400 22570R19. They have about 350 kms on them . Tires are located in Whitby, Ontario about 45 mins east of toronto. Never had any load on these tires either. Looking for 1500 Canadian for the set, but i'll split them up if the price is right. e-mail me if you are interested ride_on_mower@hotmail.com
