Tyre weight
 

i'm looking for the info again, gave a list of tyres, and their associated weights.

thanks

Yep...the post may have been on the old board so you may not find it now.

As for the outcome, from memeory the Dunlops (207Rs at the time) were the heaviest, with the pirellis being the lightest.

The weight difference was the equivalent to the weight saving from switching from standard wheels to lightweight performance items...a real eye opener!!!!

Here's some more too.

Rgds,

I wonder why some of the lighter fronts seem to have the heavier rears and vice versa ???

And, is it better to have a lighter front or a lighter rear (I don't suppose J-Lo would think so) but on a bike I read, in Twist of the Wrist I think, that you "steer for the rear". Thinking about it, the lighter the tyre the quicker the bike will steer. But on the front, you're helping the wheel crank over because your countersteering and the gyroscopic precession you create will help it. The rear wheel gets no help from precession, it seems to me that the rear wheel follows in getting cranked over simply through the stiffness of the frame...by brute force almost. That would make me think that the lighter rear would be better.
