Question:

We just purchased a new Cyclone toy hauler and have been reading horror stories on the forums about the tires that it comes with from the factory. We are wondering if these tires would be a good alternative or what you would recommend?

Based on the information I read on your Cyclone toy hauler the trailer comes with ST235/80-16 tires Load Range E, like # AM10248. These tires have a capacity of 3,197 pounds. The 3 axles on the trailer would equal at least 6 tires bringing the capacity of the tires to 19,182 pounds. This exceeds the gross trailer weight of 18,000 pounds. Unless the tires used from the factory had some issue there is no reason based on the numbers that the tires should be failing.

You could go to an ST235/85R16 such as # AM10501 as long as you have more than 0.35 inches of available space above the existing tires.

Please note that trailer tires should always be inflated to the maximum psi as indicated on the tire. The reason for this is that trailer tires are built with a thicker sidewall compared to passenger vehicle tires. If the tires are under inflated, because of the thicker sidewall the tires will generate excessive heat which is the main enemy of tires.
