When do you decide to change your tires?
All this chit chat on tire pressure, blow outs, etc. and I haven't even gotten my MH yet, two weeks and counting! Yet today, first time ever, I have a blowout on my boat trailer. I consider it training The tires are about 6 years old but they have the same situation as RV's, it sits in storage over winter, not typical car use, etc.
So I think I'm going to go on a 5 year cycle on tires for the boat trailer. Which leads me to when do people decide to change their tires on a MH? Wait for a failure? Based on time? I doubt it's tread like a car and not passing an inspection. So what are people using as a rule of thumb to replace the tires?

First I buy the best tires I can. When they show cracking or get over 6 years old I am in the market for new. My current tires are: Michelin: 295/80 R 22.5 XZA2 Energy

7 years is the absolute longest I run. I thought a number of manufacturers state the same....maybe they don't.

In Sept I put 8 new tires on my rig, the takeoffs were original dated late 2007 so they were some 9 years old and still looked great both outside and inside! I have never had a blowout on an RV in the 50 yrs I've had them but ZI have always used Michelin too. The only blowout I've ever had was a Goodyear on a Jeep Grand Cherokee.
I try not to hit curbs or run over stuff on the roadways, check the pressure before every trip and now have a TPMS. Never put tire dressing on tires except for 303 and if I'm going to sit for a while I cover the tires.

Tires in good physical condition, properly aired all the time and not run over curbs, etc rarely fail on their own.
Chronic underinflation or hitting road debris leading to severe underinflation is what causes most blowouts.
I use a TPMS, always keep tires properly inflated and don't run over curbs, store the RV indoors and the last RV I sold had 15 year old tires that looked as good as the day they were new less a little tread.
I had 100% confidence in them.

I decided to replace my tires when I could feel the MH start to wobble at slow speed. First I felt it in the front and a few weeks later, in the rear. 7 years old tires with 8000 miles on them.
I never ran them low on air but I only put a couple thousnd miles on them.

Good info here. How started the 6year stories. If tire manufacturer is saying 10yrs where did the 6-7 year theory come from? That is if the tire is in good condition?

Change the tires on your RV based on the same criteria you use for your car. When the physical condition of the tire indicates it.
Contrary to popular thought, tires in good physical condition rarely blow out on the side wall or tread. Tires that overheat because of low inflation, whether gradual, systematic or suddenly separate at the wheel bead leading to catastrophic quick deflation.
Age in and of itself has little to do with it.
At $4k a change, invest in a TPMS, take care to cover tires when not in use or store indoors if possible, monitor tire pressure all go a long way in extending tire life.

6 years. There are some on this forum who change out tires at 4 years just because it makes them feel good. Good for the economy, but go figure.

Getting ready to change the steer tires on our rig, they are 7 years old. I bought all new tires in 2010, since then all four of the rears failed between 26,000-30,000 miles, due to belt delamination. Coach is not overweight. These were tire defects.
I have no problem with the steer tires but I don't trust them. Switching back to Michelins from BFG Commercial T/A..

I was north of 200K when I bought our motorhome, since then I've added a tpms system, RV gps system, laser temperature gun, and a weather radio. All these to up the safety odds. Is 3K in tires worth it to me when ALL I hold dear in this life are riding with me? You can bet your sweet ... it is. Change them out when your wallet can stand it.
