Mythbusters Tests The Square Wheel Theory

hello dear all cr4 guru can you help

i have older ford pikup that has very much bumpy riding what could be the trouble???

it is green thx

Paint it red and it will run smoother.

It's the roads that are all wrong.

Reminds me of some of the dirt backroads I'd occasionally need to drive on when I lived in Florida many years ago. There were known as 'washboard roads' due to their similarity to the old washboards women people used for washing clothes early last century. I think square wheels would have helped. I noticed the ride got smoother once you got going pretty fast, as the Mythbusters noticed too.

It's a bit like hitting a cattlegrid - there's usually a sweet spot in the speed of attack, probably dependent on the suspension charctarististics. If only roads had regular spaced pot-holes !

It'd be fun if mythbusters had solved the axle problem for a Releaux wheel.

"Why don't cars have square wheels?"

Works for shopping carts.

Darn, I thought we were finally going to be able to get rid of the parking brake.
