Latest from OFNA
OFNA just added 4 new foam insert profiles to fit ProLine tires.
These Molded Inserts are direct replacements for stock inserts found in PL and many other popular tires. Molded inserts change the relationship between the tire and track surface by increased traction and reduced side wall flex.
To top it off these molded Inserts will not deteriorate like regular foam donuts and are reusable.
