What should be the ideal tire air pressure on a 1998 honda accord. Ritesh
That would be the wrong place to look. The tire only shows the MAXIMUM allowable pressure and not the safe, appropriate and normal pressure for the tire.
The ideal pressure is on a sticker on your drivers side door. This is developed by the engineers from all the design characteristics and handling characteristics of your car.
================== ....Bearing in mind that it's a COLD pressure, so if you drive five miles (on a warm day) to the gas station, you may have to inflate to a value about 6 psi HIGHER. It's explained in the Owner's manual. In Alberta, at this time of the year, almost every pressure measured is a COLD pressure 'Curly'
And some of those design characteristics are undesireable. The Toyota Prius and Honda Civic Hybrid both have door stickers asking for 30psi on tires rated at 44psi max. That makes for a nice, quiet, cushy ride with awful handling. My neighbor kept his Prius at 30psi and wore out his first set of tires at 8000 miles. I adjusted mine to 35, 40, 44, and decided that 35 was the pressure that I wanted, based on ride harshness, handling, and road noise. At 39,000 miles I replace my original Bridgestones with Coopers and set the pressure to 38psi.
Actually, the recommendation from Toyota on the Prius is 35psi front, 33psi rear, so 30psi is far underinflated. OEM tires on the 2001-2003 US Prius had a max tire inflation pressure of 50psi, and the OEM tires on the 2004-2005 US Prius has a max tire inflation pressure of 44psi. For 8,000 miles on the 2001-2003 Prius US OEM tires, I'd also suspect that the alignment needed adjustment, besides the tires needing proper inflation. (A lot of owners seem to like running somewhere around 40psi (with a +2psi in front bias) to prevent edge wear on the OEM tires, often seen at the Toyota recommended pressures...)
