Anyoe have any experience with these?

They will add 13 lbs per tire but wonder if they are worth the hastle..

I have the rims for these and can pick up a set but wonder if it is worth all the hastle?

Anyone one have any experience with these?

Thinking it would be better then running a spare at next years race and just swap tires at pits....

My ghetto knockoff of 'em works great. Weighs twice as much, but it's free... bald 265/75/17's from behind the tire shop. :)
