Semi Truck Tire Size Chart
A plain-English reference for common semi truck tire size markings, where they are used, and what to verify before changing sizes.
Semi Truck Tire Sizes
Start here when a sidewall size, wheel diameter, or low-profile substitution needs a second look before ordering tires.
Field Use
A dispatcher may only see “11R22.5” in a photo, while maintenance still needs rim width, load range, dual spacing, loaded radius, and fleet policy before approving a replacement.
Quick Checks
- Record the full sidewall marking.
- Compare current tire and proposed replacement by manufacturer data.
- Check dual spacing and matching on drive or trailer positions.
- Do not treat near-equivalent sizes as automatic substitutes.
