Tread squirm is for real!

Last summer, I had my first tire failure while pulling our fifth wheel on a very rough interstate, I broke one of the belts on my "E" load tires on my 1-ton. Fortunately, we made it to a tire store where I had two new tires put on. As I pulled back onto the interstate, I almost lost control of the truck, like I was driving on ice. It was the craziest experience I ever had pulling, and I have pulled a lot of miles in 25 years.

To give you some background, I have run BFG KO's for the last 15 years with no problems. They no longer make the particular tire I had on the truck, so I bought the BFG KO II's, which looked similar to my other tires, but apparently has softer rubber/side walls. After my ice skating incident, I checked and re-checked the tire pressure thinking something was wrong, and re-tightened the lug nuts. After about 1,500 miles on the truck, it didn't get any better so I yanked them off and changed brands.

I didn't have a chance to break the new tires in before our first trip, and took off on a 300 mile trip on a brand new set of tires. Again, the truck was real squirrely, but by the end of the trip, it appeared to be getting better. We drove it around for a month unloaded, letting the tires get good and broke in, and took another trip this past weekend. I can finally say the truck is back to handling like it's supposed to.

Moral of the story, don't pull a 13,000 trailer on a brand new set of tires. I nearly bought the farm five miles from the tire store on the KO's, and it took a good 2,000 miles for the second set of tires to settle in, but all is good now.
  • At work I sometimes drive a 2015 Silverado 2500HD Government truck. The original tires were Firestone Transforce, which were great, and very stable while towing. New tires were put on it in December, Iron Man All Country. These new tires are very squirmy. Like the roadway is covered in BBs or marbles. My own '78 GMC one ton SRW pickup has Transforce tires as well, and are very stable towing and unloaded. Same with the BFG T/A KO's on my 2004 F-250 SD. I will never buy Iron Man tires for any of my own vehicles after experiencing them on the Government Silverado.
  • I've experienced some tread squirm on every set of tires (all Michelins, on all Toyota vehicles) I've bought in the last 20 years.... on everything from a Corolla to a Sequoia. It is usually noticeable for about 400-500 miles. I try to avoid driving on wet roads with new tires, and if I must, am extremely careful.
