![]() ![]() There are only a few specific applications where LT tires are acceptable to use with a trailer, but they’re not usually a better option. LT tires are built with thinner sidewalls than trailer (ST) tires and aren’t as good for holding a vertical load. Related Product: Use a wireless Tire Pressure Monitoring System (click to view on Amazon) to monitor the pressure in your trailer’s tires and be warned of flats.įirst, it’s usually better to go with the tire that’s made for trailers. You can read lots of different opinions, but no matter what, there are a few things that hold true with trailer tires. There are many debates on whether specialty tires (ST) are the best for a trailer or if light truck tires (LT) are better. When it comes to getting new tires for your trailer, the choices can seem endless.

Post on TPMS settings I figure that +25% from baseline is a reasonable Question on pressure increase setting for TPMS. This is another contributor to more heat. Read the sidewall and Iīelieve you will see Nylon cap plies in the tread which were not in the Have extra components (mass) in the tread. ![]() New tires have deeper tread depth, which willĪlso make a tire run hotter, which means more pressure growth. Initial cross-link chemical bonds are broken as tire is "broken in." This Tires do run hotter than old for a couple reasons. In all probability your tire is actually 20 F to 30 F hotter than the TPMS is reporting, but this is within the expected design limits considered by tire engineers. It is also known that the metal body of valve stems and the metal body of the sensor will be cooled as it whips around in outside ambient air which will result in a lower reading. Also while it may not seem reasonable, it has been demonstrated that the temperature of the air inside a tire is not uniform. One other related item is that aftermarket external TPMS are not reporting the temperature of the hottest areas of the tire which is internal to the structure. With nominally dry air the pressure will increase by about 2% for each +10F. New tires will always run hotter than old tires. Not sure if your "test" is "scientifically" sound - You were comparing two different tires (LR-C vs. The temperature and pressure changes are reasonable for most 14" - 16" RV tires, especially trailer applications, but I will focus on your question. Is a 10 - 12 psi increase in pressure considered acceptable? If so, what should I set the high pressure alert at on my TPMS?" This compares to the average 5 - 8 psi increase I experienced on a typical trip with the old tires. The first thing I noticed was how quickly the tire pressure increased once we got on the road.Ĩ7 degree day, 60-63 mph, tire pressure on sun load side got to 75psi Obviously, the first difference was the starting "cold" tire pressure. Were any differences in the readings I had with the old tires. So, on this first outing I closely monitored the TPMS to see if there Trailer rode great, better than the old tires. " Took our first trip with the new Goodyear Endurance tires. Saw this question on temperature and pressure increase on a new set of Goodyear Endurance tires. ![]()
