Now, RV tires and their proper use cause a lot of confusion for RVers. This year, Dennis writes– this week, Dennis writes, “I’ve installed a tire pressure monitoring system. My class C motorhome calls for 80 pounds a square inch tire pressure. Driving in hot weather, they go up to 96 PSI. is that safe? Should I deflate the tires in hot weather?” And that’s from Dennis in North Carolina.
No, Dennis, you should not deflate your tires in warm weather. The cold inflation pressure is your starting point for your motorhome, trailer, car, any vehicle like that. The tire manufacturers establish that as the point where you start the inflation, and they build in a factor that allows it to– inflation to come up a little bit when the tire warms up, either due to warm weather, going down the road, or a combination of those. There’s plenty of safety margin built in there. You don’t need to worry about deflating the tires. And if you do that, then when you go to start in the morning, the tires are probably going to be too low on inflation, and then that can be even more of a problem, of course. So, don’t bother deflating them. Keep–start them at the cold inflation pressure and you’ll do just fine.
