Re: [ST] Mixing Tires



Well, Rick, you certainly keep great records of our List Chats!.  Thanks to
you, Keith and others who weighed in on the subject. This bit of writing
from the Bridgestone guy summed it up for me:

"We know that the demands placed on a front tyre are different to the
requirements of the rear tyre, and that is why the compound of our front
tyres is different to the compounds of our rear tyres. So the front BT-020
compound is different to the rear BT-020 compound and the front BT-010
compound is different to the rear BT-010 compound, etc., etc., all the way
through our various ranges of tyres. Now that you have this information you
can see that it's pointless mixing tyres, Bridgestone is already giving you
what you want when you fit a matched pair of our tyres."

While riders opinions still vary, I don't think I will mix.  A few years
back, I mixed a front and rear without problems UNTIL the front began to
show wear.  Can you say high speed head sh-sh-shake?  (Not a Sprint ST but a
heavier ST1100).  Thanks for the refresher course on mixing tires.
