Hi I am a long time customer of Discount Tires , I take my tire business nowhere else . Several years back I bought some of the Rated R's Discount Tires , The center caps stayed on for a little while but then started falling off one by one , while they had Konig's DT would replace them but then they stopped making the Rated R's and DT couldn't find any more caps to sale me . Well I finally stumbled upon a place to buy these caps and they will be delivered soon ))) . Now for the purpose of this post , How can I keep these caps from falling out again ? Is there something I can put on them to help them stay on or something ( short of super gluing ) ? Thanks in advance .
