My 2003 Teton came with Goodyear G614 load range G ,110 psi, & 3750 lbs rated. Living in California we have a 55mph speed limit for towing. I tow around 60-62 mph. I have a compressor & checked my air pressure before every trip. GVWR of Teton is 14,995. Has 7,000 lbs axles (2) weight on those 12,000 so not over weight. Lost the first one in 04 just spit the tread off. Goodyear warrantied no problem. In 05 lost two more these blew with nothing left of the tire to take to Goodyear to warranty. In 06 lost 2 more with in 10 miles of each other on a 117 degree day 90 miles out of Las Vegas. Over the following years I lost 4 or 5 more (lost track). American tires, LT tires, China tires none were ST. Last one that happened in South Dakota in 2010 did $5,000 + damage to the trailer. Insurance covered & I figured I needed to try something else. I bit the bullet & ordered 17.5" new rims & tires. Have (2) new Hankooks & (2) used Michelins. Problem solved.
Last weekend I moved those to my V3605 & the 16" to the Teton. Teton will be sold or daughter might move to Phoenix & live it. So isn't being used like in the past.
Yes the Hankooks are Made in China but we have been using them here at work on all our vehicles & trailer with NO problems. 16" 17" & 22.5"
