Tires Raidal vs Bias Ply....I know it's an

So I've searched the threads and I apologize for bringing up something that has been hashed to death but here I go.....

I've put 7600 miles on my 1300 Deluxe this summer and I need new tires, so my question is......

It came stock with bias ply tires and some would say, "stick with what the manufacturer designed the bike around." I can appreciate that feeling, but I have to ask, What are the pros and cons of radial tires?


I'm new here so excuse the ignorance. I would never put bias ply tires on my car, so what's the difference on my bike?

Thanks for all your input and experience.

From the website http://www.dunlopmotorcycle.com
Can I change my tires from bias ply to radial or vice versa?

Bias and radial tires have significantly different dynamic properties. They deflect differently, create different cornering forces, have different damping characteristics, as well as other differences. In order for radial tires to be introduced into the two-wheel market, it was necessary to change certain characteristics of the motorcycle. The introduction of the radial tire led to such things as modified frames, wider wheels, new steering geometries and suspensions. Therefore, it is recommended that a motorcycle be used with the type of tire construction that it came with originally. If a change is to be made, then it should only be done if the motorcycle or tire manufacturer has approved the change. Above all, do not mix bias ply and radial tires on the same motorcycle unless it is with the approval of the motorcycle or tire manufacturer.

This wasn't even on my radar when I changed out tires... I went from OEM tires to OEM Dunlop on the front and a Commander II on the back. (The Michelin website lists the tire as both radial and bias so I'm completely confused.) I spent 6 months like that until the front started to crack and I replaced it with another Commander II. No issues whatsoever. That being said, I LOVE the Michelins

Thank you for the replies, that was great information. I'll stick with bias ply tires.

I'm thinking you've made a good decision.

First we can't apply all that we know about the differences between automotive bias ply and radial tires to motorcycle applications. They really are two different beasts.

Second, it appears that the application of bias ply and radial tires for motorcycles is mostly dependent on the type of bike and how it is ridden.

Third, this has the potential to go the way of the many oil threads I've read and in which I've participated. Everyone will have their preferences.
