Experienced mechanics suggest that to maintain peak performance, spark plugs should not be run longer than 30,000 miles, even though they continue to fire. A. Inflate tires according to the vehicle manufacturer's recommended inflation pressure found in the owner's manual or on places such as the door post and glove box door. The same applies to air pressure limits stamped on the sidewall of your tires. Unless you load your vehicle to its maximum carrying capacity, using the maximum pressure listed on the tires will result in a terribly hard ride and may adversely affect steering control. I'd recommend radials for anything short of a Conestoga wagon.
Radials improve ride, handling and steering response.
And they deliver a more cushioned ride that is easier on suspension components than the older bias-ply tires. The slightly alkaline paste neutralizes corrosion. After reconnecting the clamps to the terminals, wipe them with petroleum jelly to help prevent future corrosion. Be careful when working around a battery because it contains a strong acid. A. Firmly apply and maintain continuous pressure on the brake pedal while continuing to steer away from obstacles.
