Ok so I'm assuming most people in here keep track of their tire pressures and if you don't SHAME ON YOU. Tire pressures are the most important part of a car and can easily plug up to 6 mpg to your total. That's right 6. Also poorly inflated tires are more likely to blow out on the road so its also a safety issure. So I ask give your car and your preferred pressures. The size of the tires also helps a little in providing an estimation of what people should inflate to.

94 Honda Del Sol:

195/65 R14, Front pressure: 37 PSI, Rear pressure: 35 PSI
205/45 R17, Front Pressure: 41 PSI, Rear pressure: 37 PSI

88 Mazda RX-7:

Uhhh I'll get back to you on this one

My dad has a tendancy to go about 5 to 10 PSI of what I prefer but at my pressures it usually elimantes most sidewall flex and I get approximately 40 mpg on my Honda at those pressures. Ok now you guys go.

30 PSI front and i think its the same for rear too ... '00 Mazda 626

well then, this is a random thread.

i usually keep em all in the low thirties as my owner's manual recommends...

99 Acura Integra

205/40/16 Front: 30 Rear 34

Numbers might been a bit off, its been a while since i've seen my car

From my experience you're best off to try and balance the tire pressure with your weight distribution. Your contact patch is a function of the weight and the pressure in your tire. So if you have a FWD car with an imbalance front and rear you can actually tweak the handling by adjusting the tire pressures. If you want less traction in the rear you pump up the pressure in the rear tires and make their contact patch smaller. You want to play it safe, you put more PSI in the front and the car will understeer more. But if you're like me and want the max grip possible you're better off to do a slight imbalance with more in the front than the rear and usually get the most neutral balance that way.

You in college now Black Fire?

All tires on the GTI are 225/45R17s (90H rated for the stock Michelins)

Front Pressure: 33 PSI
Rear Pressure: 42 PSI

Yea I think I reversed the numbers, I always double check my manual before I do it though.

And yep in college, I'm home once a month so that's the only time I get to drive it. But I'll be home for winter break the 14.

Muahahahaha SUCKA

*has car with him at college*

I couldn't live without it.

how much do you pay for parking?

$270 per academic year

35 front and rear.

It's supposed to be 35 front, 32 rear, but I don't care that much and/or notice a difference, and the tires all wear evenly anyway.

Doesnt seem too bad. At my fucking highschool it's 90 bucks to park at school. $245 for a spot with a plug.

A...Plug?

Wow, parking permits at my high school were free.

I didn't bother though because I lived a block away. Hell, there were days when the traffic stretched to my house anyway.

heh I paid $35 a semester to park at high school.

it gets cold in winter?

last year it was free. Pisses me off since half the time their too lazy to enforce the parking and the lot fills up before i get there and half to spend 20 mins fuckin around trying to get my spot.

Front: 275/60-17 30PSI
Rear: 275/60-17 32PSI

For highschool it was free, here in college i think it's $110 an academic year, but freshman can't have cars, so that's why I don't have mine. I can't wait to have it next year so I can cruise through all the back mountainous roads. It may not be like the Cali mountains, but sure as hell is a lot better than the flat land of long island.

Kinda nerdy. Everytime I go to the gas station, I check my tire presure, if it needs some air I give it some. My tires don't loose much air, I've had to do it once this summer. Maybe 'cause they are brand new.

I keep my fronts 35, and my rear around 32.

Bah, there are no good driving roads nearby...even though we're in the california hills. The closest good driving roads are 15-20 miles away

15 - 20 miles? That's nothing. I'd be there all the time. On the weekends, when the weather's nice, I was putting on about 300 miles. All cruising miles. For long weekends, like when I come back from college, I'm putting on around 500 miles.

well, 15-20 miles is bad for me when I only need to go 3 or 4 when I'm home to hit up my favorite roads.

thats cheap. but then again, you arent in a city. were i to park here, it would be around $1200 a semester. ($2400 a year) thats more that i pay to eat.

yeowch, that's awful. Yeah, parking here isn't bad...there's lots of places to park and all that, and it is relatively cheap as universities go (it's one of the cheapest unversity parking permits I've heard of)

14PSI then the manifold blew.

That manifold must have been welded with JB weld to blow at 14psi.


I run 35psi f/r in the winter on the Blizzaks.

In the summer I usually run 42/40. I keep the fronts that high so the wear is even across the tread. Any lower and I just chew up the shoulders.
