thanks guys for the great advice! i might go with the Michelin cup or nitto invos.

thanks alot cannga for the info about how much different tires weight!

 

Does any one have the weight of the Hoosier R6's ( 19" )?

 

Here you go.

 

I couldn't find the exact same size, but it appears Hoosier in something similar to Turbo size would be around 48 lbs (one front plus one rear), putting it about same as Pirelli Corsa and Michelin cup.

BTW, thanks for the info on your web site. My table would not have been possible without Tire Rack's info.

 

Glad my tire weight ranking table is helpful. It was a slow day at work -- . Anyway thanks guys for the positive rep remarks. I too am surprised that tire weight does not come up in every tire review or discussion. Almost never discussed as a matter of fact.

Abdullah (cayenne_USA) is of course absolutely right. The tire adds weight where it hurts the most - the outer part of a wheel. Further distance from hub means higher angular momentum, and large angular momentum affects steering, acceleration, and braking.

If the rudimentary physics I took at Berkeley has taught me correctly, the higher mass itself increases (linear) momentum, the up and down motion of a wheel on the road (as oppposed to the rotation of the wheel), and this affects ride and handling as well.
Essentially every critical parameter of a good sports car is adversely affected by mass at the rim, tire, and brake, aka unsprung mass.

 

I found the RE11 adequate on the street but terrible on the track.

 

if you can get a set of MPSC for $1000 like you told me don't miss this deal.
