First off I'm positve those tires were made in China. Second if u google Sailum Chinese made tires u will find lots of evidence they r also junk. There's more than 1 reason they're so cheap. Buy the Goodyears or look at the Bridgestone s which I have on my 14k 5r. 5k miles and they look brand new. Always, always check cold tire pressure before any trip. Remember that the rv industry now is owned by very few corporations. Most of the quality manufactors went bankrupt in 08 crash. So everything is geared to make rvs as cheap and light as possible. Lippart now makes 90% of all the frames, suspension systems and axles. Their business model is to work with rv industry to make everything cheaper and lighter. Now take in fact that rvs take a large amount of seasonal workers to assemble unlike the auto industry. So what I'm saying is there's no way an rv can have a correct alignment from the factory. Even if it's close parts will "move" under the heavy weights. Without a proper alignment you r really dragging the tires sideways down the highway. Then we won't even think that the rv tires were never balanced!! No u don't feel in the seat of your truck but your rv tires are merrily skipping down the highway leaving rubber behind. My family's life and possibly others plus $100k of truck and trailer is not worth trying to save a couple hundred bucks.
