Trailer tires

[Rory McNeil]

I recently completed a nearly 4000 mile haul from coast to coast across Canada, towing my heavily loaded 24 foot Well Cargo enclosed trailer. I weighed the rig in Manitoba, and was quite surprised at the weight my poor old V10 was dealing with. Not counting the tongue weight, the 2 trailer axles were carrying 9600 pounds, so I did have concerns for my 15” Maxxis ST225/70R15 load range E trailer tires. But they made the trip with zero issues. Even though the tires were about maxed out. I did run them at 75 psi cold, and other than a few stretches going down some big hills ( had 2 days in the Rocky Mountains in British Columbia and Alberta), I kept the speed at just under 65 mph. After a blowout a few years ago, I was surprised to find that most trailer tires are only rated for no more than 65 mph. Between keeping the speed down, and tire pressures up, neither of my spare tires saw any service during the trip. Pretty happy with the Maxxis tires.
