"These look tuff. I should be able to keep from gettin flat for a good long while !"
"I have used Mr. Tuffy. liners for years. They are lightweight and effective for preventing imbedded glass, thorns and sharp objects in the tire tread from puncturing the tube. Mr.Tuffy liners are the best option for presto valve tubes which normally can’t take flat prevention fluid."
