After reading much of the discussion on tire failures in this forum, and having suffered one myself with the factory installed "China Bombs" on my Bighorn, I wondered if anyone has experienced or know of someoone who has experienced a wheel failure. I don't recall seeing this in any previous discussions. I mention this because I replaced my (E) 80psi rated tires with (G) 110psi rated tires, without giving any thought to the rating of the wheel. I have read many threads about upgraded tire replacement, but very few have mentioned wheel replacement along with the tires. This leads me to believe that either the majority of wheels on Heartland products are rated for 110psi or installing (G) rated tires on (E) rated wheels has not been much of a problem. I gotta go check mine as soon as the weather clears.
