use 18 in. tube on klr rear ?

[Fred Hink]

That's his opinion. Mine is slightly different. You don't need a HD tube if you are riding strictly pavement. A HD tube won't create more heat than a standard tube or running tubeless if running the proper air pressure. A HD tube adds to the mass of the tire and can contribute to holding heat longer but I have seen no evidence that a HD tube actually creates more heat. If your tire is under inflated, the flexing of the tire will create heat whether you are running a HD tube or a standard tube. Flexing of the tire at slow speeds is not a bad thing usually since you will gain added traction and a smoother ride, while being able to dissipate the heat fast enough to not be a problem. Tires run low or over loaded on pavement can build up heat faster and could cause a problem with accelerated tire wear or eventually a blow-out. A HD tube won't resist a flat by a nail any better than a standard tube. The advantages of running a HD tube is mostly for running off road and resisting a "pinch-flat" by hitting a rock hard enough to pinch the tube between the tire and the rim. A thicker tube will take more effort to pinch-flat. You shouldn't ever be hitting anything on the road that would benefit from a HD tube (pot holes maybe but I try to miss those). But you pays your money and takes your chances.

The tire guy I go to indicated that the HD tubes are not a good idea as they can heat up more when on the road alot? I had requested a HD tube after a flat on the front and then went with normal after his recommendations. He does quite a few tires/tubes for various bikes and I trust him? Was he full of it?
