My tires have the word “groovable” on the sidewall. What does this mean?
Most commercial truck products (all brands) have sidewall stamping designating them as regroovable. Regrooving is typically performed on tires used in metro bus service. When bus tires get worn, there is a regrooving machine which actually cuts grooves on the worn tread so that these bus tires can continue to run prior to retreading. Bus tires are designed with extra rubber under the crown area of the tire. RV owners should not be concerned with regrooving their tires.
