I had mine put on by Monroe Muffler. Less than 10k miles and side wall started to bulge on one tire and rubber is showing a split. If anything it looks like something that happened while mounting the tire. Monroe says it looks like pothole damage. I have not hit any potholes with my truck in fact my Wranglers from orig equip lasted over 80k with zero problems. This by the way is coming from the same Monro shop that gouged groves in my aftermarket rims on my last car mounting tires. I am told that Hankook will not back up their product or defects in their product according to Monro. Sticking to US mfg tires from Goodyear or Bridgestone from now on. Hankooks are weak and have poor traction if it is not 100% dry outside. Staying clear of Monro from now on too.
