Recommended Tire Pressure

Look on the tire in case the tires were ever changed to anything that differintiates from your car's recommendation. I have low profiles and the service place still set it rediculously low (for those tires) because of the vehicle's recomendation.

Unfortunately, the car manufacturers use the tire pressure to assist in a softer ride. I run my 2002 LS430, 1991 Buick Reatta, and my 1977 Excalibur at 38 lbs. All weight well over 3700 lbs, and I like the firmer ride and better handling. The most reliable way to evaluate your pressure is to increase it to 35 - 38 lbs (cold) and then, if you like the handling, watch your tire wear. If your tires are to soft, they will wear at both edges of the tread. If they are over-inflated, they will wear in the middle (crown0 of the tread. If you'll check the wear pattern, you can determine the state of inflation. They should wear evenly.

So true tire wear is a good way of checking to see if your running the right presure that and the handling capabilities of your car also throw in if you have worn out front-end parts ie control arms top bottom ball joints shocks etc
