I'm running 5 lug Fuchs on my 914 and have had two valve stem failures since wheels were installed 6 months ago. Both failures have been on the front and on opposite sides. Failures both seem to be from shank section of stem and have shown up as slow leaks luckily and not total failures while at speed.
I use the best tire shop in town for mounting and balance and see many high end cars worked on there. Is my tire guy missing something? The stems used are a rubber material. I seem to remember seeing some type of stem support back in the 70's. Are these required? My car does see 100 mph on a regular basis and 130 or so on occasion if this makes a difference. John |
