Michelin Pilot Power mixed with Stock IRC front? BAD because Bias w/Radial?

kkel19 · April 29th, 2013, 09:03 AM

Hello I am planning to switch my stock tires rear to the 150-60-17.

I have the stock dunlops in the front.

If I put the michelin in the back is it bad because the front stocks are Bias-ply and rear is radial?

Please advise!
Thanks!

It's not bad as long as you don't out ride the traction of the front. The radial may inspire a sense of traction that the front can't comply with. Your only as strong as your weakest link.

I would recommend just putting 2 new tires on. Trust me its the better choice.

Kel,

As Chris has explained above, nothing catastrophic will happen, unless you really push the limits of traction and stability (something to never be tried in public streets).

I have never rode a bike with a mix of radial and bias belted, but I have read that some stability handling may occur.

"Don't Mix and Match Bias and Radial Tires
Bias and radial tires have significantly different dynamic properties. Bias, bias belted and radial tires have different construction types and therefore have different abilities to carry side and peripheral forces as well as having varied damping characteristics. The introduction of radial tires required changes to certain characteristics of the motorcycle. The development of the radial tire led to frame modifications, new steering geometries and suspensions. That's why it is recommended that a motorcycle be used with the type of tire construction that it came with originally. Do not mix bias ply and radial tires on the same motorcycle unless it has the approval of the motorcycle or tire manufacturer."

It is not recommended but it should not be catastrophic if you do. Listen to what csmith and motofool wrote.

Be careful. I ran out of time this weekend before a trip and only got to mount the rear Pilot on my bike. you could definitely feel it. It felt a little squirmy.I even pushed (slid) the front tire a few times in some of the 180 degree switchbacks I was riding on (Tail of the Dragon). The front time is the original IRC and my bike is a 2010.
