There are great sites that dedicate themselves to wheel weights.

But what about tires? More specifically, I would like to know the different weights of different sizes (in width, sidewall and diameter).

 

Call Tire Rack.

 

Ditto.

I think they hate me, I call there all the time asking for this about
different tires.
I wish they'd just post the info!

 

i think they would if it would be a frequently asked question

truth of the matter is most of the consumers dont ask. and even to the import enthusiast, im sure a good percent of them dont ask either.

so really its a small small volume of people who wants to know
