You might want to check your link to "SuperDurometer Track Bar Bushings". It tried to send me to my "Cart" which was empty.
The part about tire pressure doesn't make sense to me.
You should have somewhere around 30psi or so with stock tires, and the larger your tire are, the less pressure they should have.....
As an example, I run around 38psi in my 37′ tires.
A stock tire gets 30psi, but a 37" tire gets 38 psi, but the larger the tire the less pressure they should have?
Overall a very informative article. Thanks for posting.
