Video shows why tire interply shear happens

RV Tire Safety

with RV tire expert Roger Marble

As we head into the Christmas holiday, most of us are not thinking about our tires.

Here is a quick post that might help people with a better understanding of how and why tires can develop tread/belt separations. The video is focused on multi-axle RV trailers but ALL radial tires have this force that is called “interply shear.” It’s just more obvious on these trailers.

Now go finish your shopping. One gift suggestion I can make is a good digital pressure gauge. The gauge I use as my “Master” is the Accutire MS-4021-B digital tire pressure gauge. Learn more or order on Amazon.com.

To help reduce shear I always turn my fifth wheel as wide as possible, especially on pavement. Many times you can’t though, such as when backing into a tight spot. But when you can it does help reduce shear forces. Also inflating trailer tires to maximum sidewall pressures will help reduce it somewhat.
