I purchased a utility trailer 6x8 to haul my two scooters (1000 pounds). It came with the cheapest Carlisle 13" bias ply tires they make. This trailer will be pulled at 75 mph for up to 14 hours at a time. Thinking of upgrading to the Carlisle HD 13" radials. Did not see Goodyear Endurance tires in this size. Sound thinking or waste of money?Update purchased Hankook tires for the trailer. They are within weight limits and have a 118mph rating.

my advice and i take my own advice is to never skimp on tires.

Will larger tires fit under the fenders? I switched my utility trailer from 13" to 14" tires to get higher rated tires. My 14" are rated at 1900 pounds at 60 psi.

On small lighter weight single axle and tandem axle trailers I've always ran P tires. I just sold a 5' X 10' tilt trailer with 13" P tires. That way no worries with speed ratings. Many light weight utility type trailers (single axle and tandem axle) come OEM with P tires. P tires load capacity is to be derated by dividing its capacity by 1.1.... so get a size with plenty of capacity. I don't think other Carlisle tires carry the new speed ratings as the HD line...check it out.

The trailer and scooters will be under 2k so weight shouldn't be a issue. The softer car tires would also be easier on the scooters as well over rough roads.
