I have sale, five Mr. Tuffy tire liners.
These liners eliminate 99.99%, of the flats, caused by the "Dreaded Goat-Head Thorns".
One fits a 20 x 1.5-1.95 tire.
The other four fit a 20 x 1.95-2.5 tire.
Asking $5.00 per liner, plus shipping.
Contact me via the "Contact Seller" button if you are interested, or need more info.
Thanks for looking.
