I have read that over inflating tires causes premature wear but it is not as serious as underinflation. yet many people appear to be inflating to max psi and just going with it. sure would like to get any many thoughts on this as I can? again, I want to avoid problems. we are on an extended trip and will be towing a few thousand miles over the next few months. are there any ex-tire company experts out there to respond?
Ok! I see other have respond to you also telling you to inflate to the maximum air pressure on the side wall of the tire. I agree!
Now I do use air inflation tables on my truck tires but I am running non-stock size tires on my truck LT285/70R/17 126R Nitto Dura Grappler tires. I also know the actual axle weight loaded and unloaded; so I know what air pressure to use.
I do know of others who use the tire air inflation chart for trailer tires but they also know the individual wheel weights of their trailer. They have actually weighed each axle and than each individual tire to get the proper loads so they can use the inflation tables. Have you done this weighed each individual tire to see what the weight that tire is supporting? If not air the tires to the maximum air inflation listed on the side wall of that tire and be safe.
I bet you will even see a cooler running tire air temperature on your TPMS system. Under inflated tires will run hotter than properly inflated tires.
