Air pressure check

Hey all
Just last weekend I was out working om my Mustang, replacing the exhaust system (Flowmaster American Thunder series), and decided to check the tire pressure while I had it in the garage. Boy what a shock

Now I work as a mechanic full time and check about 36 tires a day (Full size bus tires) but I seem to never have the time to check my own tire pressure. Here is what I found

91 Mustang: 15-20 psi normally 35 psi
93 F-150: 10-12 psi normally 35 psi (32 in tires)
87 T-coupe: 15-20 psi normally 32 psi
57 Chevy Wagon: 8-10 psi normally 32 psi(it has not been on the road in 2 years)
06 Fusion SEL: 35-35 psi normally 35 psi(Nitrogen filled at Costco last week)
Raleigh Mt bike: 20-25 psi normally 65 psi
Big red wagon: 4 - 6 psi normally 20 psi
daughters bike: 15-30 psi normally 45 psi

Now with gas going for $4.32 a gallon for the cheap stuff (here in Washington) we all need to do what we can to get every last mile on a gallon of gas. I was surprised at how low they were but not that they were low at all.

So I recommend that everyone go out and check the pressure in ALL of your tires and and make sure they are where they need to be. Then come back and post your results. We should get some pretty interesting readings..

Don't lie on the results. tell the truth and lets see how well we are at checking our tires.

lf 30.5
rf 31.0
lr 30.0
rr 23.5

now the thing is i changed the oil last week and checked over the car, so i expected it to be ok, guess not, seem i have a slow leak on the rr. and i just got back form carlisle last night, a 325 mile round trip! BTW i keep my 88 TC at 30-30.5 cold

now my truck was normal. should all be 35, changed the oil on Thursday, guess i forgot to check the tires.
lf 29.5
rf 35/0
lr 28.5
rr 34.5

Tire pressure helps a lot for gas mileage. I overinflate mine, I run 50 psi in my 44 psi tires, and 44 psi in my 35 psi tires. The cars roll much better. Im not too worried about uneven wear.

Obviously if Im racing or something I would be letting some air out but 99.999999999% of my driving is getting from point A to point B.

My dad has regular road tires on the front of his ranger and LT tires on the back. The fronts are rated 35 psi and the rears are 50 psi. I put 40 psi in the front and 50 psi in the rear.

Narrower tires also help. You could try getting a set of 205's or something on 15's and switch them when you feel spirited.

I try to check mine (in 5 vehicles + yard equipment)
At least every month or two. I pretty much know which tires loose air and how fast. I tend to run 3-4 psi over the recommended "cold" factory inflation recommendations. Some vehicles tolerate (uneven wear) more over inflation than others.

I check mine (in all 3 cars) every couple weeks, or whenever I'm doing something to one of them. They all hold pressures very well. I run 35 - 40 in all 3 cars (2002 Cavalier, 88 TC, and '91 Caravan) with Cavy at 35-36mpg, TC at 32 mpg, and van at almost 30mpg.
