Tire Shred

[CornRickey]

more times than not trailer tires are replaced due to age or failure due to age than being written out. Seven years is the general rule but I'm more in the 10 year range. All of my tires that won't wear off prior to age ( boat and rv) are stored inside and protected from uv 95% of the time.

Replaced mine last year due to cracks in the sidewall- the ones that came on my trailer were car tires. I read somewhere that trailer tires are made with a different compound, more resistant to UV and stresses that are put on the while towing. So far so good...now I cover them from the sun, and coat them with tire shine that says it blocks UV. Only time will tell. Oh, and I am running 50 psi.
