Don't leave the dealers lot with chinese tires. At that weight you are close to needing G rated tires. Goodyear G614 is the choice. Michelin XPS RIBs are rated at 3042 each. So you can go to around 12K on the trailer axles with them. They are all steel construction like the G614 GYs. Repeat, do not leave the lot with chinese tires, they are for display only! SNOKING
