Question:

I have an Aliner fold down camper, Total camper weight loaded is 2000# , I have the tires mounted on the AM 22329 Sendal wheels,inflated at 60 psi. My question is should I worry about going 70 MPH on the interstate with the tire rated at 65MPH ? I just finished a 4500 mile trip without any problem, checking tire temp. at every time I have stopped, they seem to be running cool. one tire has a load rating more then the total WT, of the trailer. Should I be comprising the safety. of the tire ? PS. Tires and wheels were Balanced

Going 5 miles over 65 is not going to damage a tire if you are within the capacity of the tire and it is inflated to the max psi rating on the tire. I still would recommend keeping it at or below the speed rating though to avoid any potential issues down the road.

With that said there are some tires that are rated over 65 miles per hour. If you have ST215/75R16 tires I recommend # TTWTRTM2157514D. This is a load range D rated for 2,200 pounds at 65 psi and has a speed rating of 81 miles per hour. Tire # TTWTR21514 has the same speed rating and is the same size only a load range C rated for 1,870 pounds at 50 psi.

If you have ST205/75R14 tires now then we have a load range C, # TR20514, rated for 1,760 pounds at 50 psi, and 81 miles per hour. I would feel much better if you went with one of the above tires since they are rated for higher speeds.
