I'm having problems mounting my slicks on the 99 V6 rims I got. I was going to use tubes from SummitRacing but they have a metal valve stem that doesnt fit through the hole in the rim. Anybody ever seen this? Also, I tried doing just the tires with no tubes and the tire just wont seat all the way even with simple green or grease all over the rim. Anybody ever mount slicks and had these problems? Do you gents use tubes with your slicks? I dont plan to go below 12 psi. Let me know all your stories so I have an idea. If I need to use tubes I guess I need to find a brand that doesnt have a steel valve stem with threads. Thanks Scot Rod
