Description
The Prema PB-4 is a 2 ply square bias repair with the large ply construction that bias casings call for. It repairs crown, shoulder and sidewall injuries in all bias ply tires, tube type or tubeless.
Install it with Prema Ultra Fast Dry Vulcanizing Cement on a buffed, cleaned liner, and the grey high-tack bonding gum cures into a permanent part of the casing. Match it to the injury and ply rating on Prema's bias repair chart. Fill the injury channel first, because a patch on its own is never a complete repair.
This is the PB-4: 4-3/4" x 4-3/4" square (121 x 121 mm), 2 ply, with a 2 year shelf life.
This listing includes 1 box of 10 patches.
