Interesting. I didn't know Honda specifically recommended bias tires for the 1500, but I'm curious. How would a purpose made radial not be as safe as a bias tire on the 1500?Honda recommend a Bias ply tyre for the 1500 NOT a radial ... Stay safe ,stick with the manufacturers advice
Well said John . That's why I like your input on the technical matters - they are always simple and to the point :waving:.A radial tire flexes differently to a bias, in fact very much different because of the different way the cords are laid up etc.
Because of this it will impose different stresses on the structure of the forks and so on. Also it will have different requirements for steering geometry.
One has to assume that in designing a bike this is all taken in to account, and that using the 'wrong' tire will result in less than design performance.
In the end it may be more down to liability than anything else. Honda did their sums one way, they are not going to countenance any deviation.
Just to be clear, the only reason I mentioned the car tire was to illistrate what the owners manual said and what it didn't say. I didn't want to get another car tire debate going, and I'm not suggesting you do either Kit.The reason the 1500 manual says specifically not to use a CT is because the MC wheel and auto rim are different sizes. Trying to force a CT unto the larger 1500 rim as has been tried in the past tends to tear the tire bead, and it does not like to seat even with over 100 pounds of pressure in it. A CT is designed to fit various automobile rims, and does have a tolerance in it, but the rim of the 1500 is just too big. Hence the warning.
The only thing that causes me question , with the Shinko, is will it actually work on the 1500? I really do not know as I have never seen one installed on the 1500. I do know a radial tire is wider, and flexes more like a pancake under stress, so will it rub on the frame of the 1500? That would be my main question about them.
