RV Tire Safety: Is it OK to regroove a “regroovable” tire?

with RV tire expert Roger Marble

My Goodyear tires say they are regroovable. Do you approve of this and who does it? I am located in Indiana. Thanks in advance. —RVForum writer

“Regroovable” is on many HD truck tires. It means the tire was designed and made with extra thick rubber under the tread pattern. Many truck tire shops can cut a partial pattern into the remaining rubber after the tire has been significantly worn. There are guidelines provided by the tire companies on the depth, etc.

HERE is a short video. [Note from editor: Interesting to watch!] You may notice that in the example the tire is a “lug” or “heavy traction” tire as used on the rear of units such as dump trucks.

Regrooving only provides more tire wear miles and will not extend the long-term life of a tire based simply on age.

You would still be constrained by the published guidelines of 10 years max no matter what the visual inspection indicates and the act of “regrooving” the tread pattern will do nothing to improve a tire’s durability.

A downside of a tire being “regroovable” is that the heavy, thick tread will almost certainly give you worse fuel economy as most of the tire’s “energy” is consumed in the tread region.

That sounds like my post on an RV forum I belong to! I also live in Indiana and have Good Year re-groovables. You wouldn’t by any chance have the handle of Tireman on RV Forum?
