Very good article.

If I had a dime for time I heard "I gotta have lightweight wheels!", I could close the shop & retire.

Good read! Just as the article stated, I was one of those that aware of the benefits of the lightweight wheels, but overlooked the good of having rigid wheels.

Yeah, a lot of people tend to take one specific little spec to the max sometimes and not look at the whole picture. I remember reading this article a few months ago. Great article.

Rigidity is important for lateral loads, pretty obvious really...

What is surprising to me, and I had no idea this happened, is how the tire shifts it's position along the wheel!!! That's ****ing crazy!

I remember seeing an argument about balancing the tires and rims separately for this reason:

Add weight to balance the rim first, mount the tire and then add weight to balance the tire on the rim. That way, if the tire slips, the difference in balance is smaller.

I don't know if anyone really does this, but its an interesting idea.

i would like see this test given as a blind test.

in the article the driver claims he can feel the lightweight rims...

i'd like to see him NOT KNOW which rims are on...

in the 4 wheeling world, there is various kinds of methods like using bead locks. this is mostly to prevent loosing a bead though.

i do rememer seeing/reading beach buggy racers using screws to just screw in the bead to the rim to prevent it from slipping...

Yeah, I remember this article a while back too... and then thinking...

WHERE ARE ALL THE "RIGIDITY" SPECS WHEN WE BUY WHEELS? ;P

Really, this is just another "keep the customer dumb, give him only the info that can persuade him/her to buy the product you are selling"

All i can remember seeing is the maximum load rating.
