Running below 40 psi, you can end up with small hairline cracks and a bent wheel due to impact, and also you can ruin the sidewall of the tires because it's underflated, which means new tires and they don't come cheap in 20's and 22's.. (btw, you cant fix the sidewall of any tire  ) Imagine a wheel barrow filled up with sand, and the front tire was at 5psi instead of the normal tire pressure, try pushing it!! It's freakin hard to push and manuevor, in most cases the wheel barrow tire will de-bead itself from the rim.. same thing with car tires.. |
I think you are right, I was driving on the highway yesterday and the car felt heavy like cars feel when they dont have enough air in the tires, like in winter driving and I could not get the car to avg over 21mpg's on the highway I usually get 26-27.5 mpg's. The first thing I thought was that my tires are under inflated and in the Hampton Roads area of Virginia which according to the local paper ranks 48 out of 50 in the worst road in the nation, I had better put a little more air in the tires.
SIDEBAR: Guys Im serious these roads suck. I came here 16 years ago and today they are still working on the same highways and it never stopped, there has always been construction on the same highways and they still have not gotten it right.
