I've gotten new Vredestein Sprint tires for my 66 SS with original steel wheels. While the tires are "tubeless" Do I still need to put tubes in them for the original steel wheels? Don't want to do it if not necessary, but the old Pirellis had tubes.
I agree with a caveat.. it is difficult to find the proper stems that will work but I have found a solution if you only have access to the bulky kind. Take a razor blade and shave the base exposed inside the wheel by about 50%. This gives some flexibility to the base of the stem to alow for the conformity and it seats very nicely and around those acute curves. I did this as an experiment 15 years ago and the wheels do hold air without a tube and any leakage. Some of the bigger tire stores will have a variety of stems but it will take some scouring and frustration to find the right kind with a smaller sealing seat that works without modifying it.The rims tell you what to do. The early rimns had insufficient space between the valve hole and the webb of the wheel to allow a tubeless valve to seat properly...in that case a tube is necessary.
