Travel Trailer Tires

Keep them aired up properly and don't overload them. That is the cause of the vast majority of blowouts (road debris is up there also but not much you can do about that).

Keep in min the supposed china bombs are mostly the result of 90% of trailers coming with them, so no surprise 90% of blowouts come from them but some people are still shocked. Then they buy the expensive brand, watch the weights and air pressure and convince themselves it was the brand.

Always bought the cheapest brand that meets the weight specs as my dad did before me. 1 blowout between us in 60-70yrs of towing and that was a broken leaf spring that swung out and ate the inside of the tire...no brand was going to survive that.

I have two trailers with Goodyear Endurance. They are made in the USA.
The Endurance replaced the Marathon.
For a given size, the Endurance has a higher load rating than most other ST Tires.
The Endurance has a higher speed rating than most other ST Tires.

New tires on my cargo trailer

All four of my rv trailers came with 15"/16" ST type tires. I've always sold them and went with 15" P tires on 3500 lbs axles and 16"LT E tires on 5.2/6k axles.

This way I can run 45k/55k miles over 7-8 years with no issues at any speed.

On my non rv trailers with 7k-8k axles I use commercial grade all steel ply carcass 16" ST S637 Sailun load G. Also trouble free and easily go 60k miles in 7-8 years.

Good tire brands depends on my trailer OEM axle/tire size and load range capacities plus a good 10-15 percent reserve capacity.

Goodyear endurance on both my trailers

Carlisle Trail HD, excellent tires and no complaints.

Currently using Goodyear Endurance that are 4 yeas old. Goodyear warrants them for 6 - time will tell.

I went with good year endurance and bumped the load rating up to the 80 psi one. Knock on wood 4 years no issues.
