Could 10 year tires really be safe?
Hi all. We have a MH with tires that are original. Manufactured in 2005 (the tires). We have taken it to get new tires now twice at the local truck/tire center and while I'm sure they would have loved...

Nobody has ever conducted a test under real-life conditions. Who knows for sure how long my Michelins will last? There's no incentive to perform the test.
If my tires only last 7 to 10 years, regardless of care and mileage, it becomes obvious that traveling in the comfort, and convenience, of my big motorhome is probably something I can no longer afford (considering all the other costs).
The problem is defining what are "real life conditions". Where do you live? How fast do you drive? Where do you store your RV? What is the exact load on each tire? Have you ever hit a curb? What are the dimensions Length, width, depth, edge sharpness of the 20 largest pot holes you have ever hit and what was your speed for each?
Another problem if you were to try such a test. How would you handle the changes in rubber compounding and manufacturing process over a 10 to 15 year timeframe?
The estimate of 5 to 7 year life for most RV tires with a 10 year max is just an attempt to provide a reasonable balance between the shorter life of tires run at faster speed with higher load in hot temperatures and the longer life of tires run 20% under-loaded, in cool temperatures with the tires stored in full shade.
