The industry trend for tire sizing has been towards low profile sizes.

Load Carrying Capacity

The chart below shows the comparison between typical standard section and low profile tire sizes

Benefits

Weight Reduction

• Average tire weight is 4 lbs less per tire for 22.5" low profiles.
• Average tire weight is 7 lbs less per tire for 24.5" low profiles.

Tire Footprint

• More resistant to irregular wear in steer position.
• Increased vehicle ride and handling stability.

As shown below, when load carrying capacity is sufficient, converting to low profile tires offers several benefits, and results in a lower operating cost for the end user. Note, drivetrain/gearing must be taken into account when converting to low profile tires. This involves the engine RPM, transmission, drive axle gear ratio, and tire RPM.
