Sticker in the door panel recommends 34 PSI, front and rear. Maximum pressure on tire sidewall is 44 PSI. What do you run for air pressure? Have 2500 miles on a 2002 ZX3 and find it a blast to drive. Bill

Hi Bill, I used to keep mine around 30 all around, Milwaukee has some terrible roads and I was getting a quieter ride. My Backseat has been down since the day I bought this ZX3... 15 months and no problems. But now that I commute 166 miles roundtrip 4 days a week. I keep the air pressure at 35 all around...the ride and handling is great...mpg is not too bad..36 if 70 mph, 29 if 80 mph. Now if These sorry Firestones will start to wear, I can replace them with some decent tires. 13,000 and very little wear due to mostly freeway mileage. Jay

44psi it's a maximum pressure allowed! If U wear Firestones - they R very sensitive. Keep the pressure ~35psi and check it each 2 weeks if not more often. If the pressure is lower it's easy 2 blow them of in some pothole as it happened 4 me once. On my ZX3 I'm wearing Goodyears R14. They R OK but even with often alignement and balancing wearing not evenly. Will change them soon on some Michelin or Japanese stuff. On My ZX5 (wife runs more often)Firestones R15. On a road even slippery they R keeping much better then GY. I'm in Chicago, but envy WA - they already R allowed have studs in winter, especially plasic ones which I've tried in Europe. Have a smooth ride!
