Folks,
I'm considering changing to tubes from tubeless rear tires. The question is: Do any of you think I need to get special ("high speed" - 300+mph) tubes or will just any old J.C. Whitney pool floaters work? BTW if the answer is "yes", I need special tubes, then where can I get the recommended rubber?
Thanks, and see ya' on the dirt/salt...

Bridgestone makes tubes for radial tires. You can really fell the difference between an el-cheapo tube and a good one. The nice ones are thicker and stronger. My choice is to call the folks that make my tires and ask them what they prefer.

Jim, check with the manufacturer of your tires. We run tubes in the front of the lakester, they are very thick and heavy aircraft tubes for the matching aircraft tire. Run plenty of air and talc if you go tubes. We ran one low once and the tire had an internal "fire".... tube melted a little and lost air.

I would not run JC Whitney tubes no matter how fast you're going to go.
I have had el cheapo tubes pull a part in my hands at a seam shaped in a zig zag.
( like from those sewing scissors .) that is what it looked like before it pulled apart also.

Jim, have you had an issue with tubeless tires that will be helped with a tube?
Someone smarter than me could do the math on the centrifical force trying to pull the tube away from the Wheel at the speed the wheel is running at. And that would have to be overcome by the air pressure to hold it to the wheel. Then, how do you keep the sides of the tube from sliding and tearing the rubber along the sidewalls? Coeficient of friction there?
There seems to be a lot going on here. Those issues would make running tubes risky to me. Unless it's already being done without these issues.
I read what Stainless1 posted and the heavy tube there is their answer, maybe even the material is different than a normal automotive tube.
