Most 22.5-inch truck tires fall into low-profile, metric, or wide-base groups, and the right match depends on load, axle, and clearance.
A good 22.5 Inch Truck Tire Size Chart does more than list numbers. It helps you tell whether you’re dealing with an older tall-sidewall size, a lower-profile metric size, or a wide-base single. That matters when you’re buying replacements, checking clearance, or trying to match tires across an axle.
The easy part is the “22.5.” That number is the rim diameter, not the tire’s full outside height. A 275/80R22.5 and a 295/75R22.5 both fit a 22.5-inch wheel, yet they don’t stand the same height and they don’t carry the same load in every build.
How The 22.5 Sizing System Works
You’ll usually see one of three patterns on a commercial sidewall:
- Conventional sizes like 11R22.5 or 12R22.5
- Metric low-profile sizes like 275/80R22.5, 295/75R22.5, or 315/80R22.5
- Wide-base sizes like 385/65R22.5 that run as singles in some jobs
What Each Part Means
In a size like 295/75R22.5, the first number is the section width in millimeters. The second number is the aspect ratio, so the sidewall height is 75% of that width. The “R” means radial construction. The last number is the wheel diameter in inches.
In a size like 11R22.5, the sidewall doesn’t show an aspect ratio. That older style uses a section-width style code, and people often think it’s interchangeable with any nearby metric size. Sometimes it is close. Sometimes it isn’t. You still need the maker’s data before swapping.
Why Low-Profile And Conventional Tires Feel Different
Yokohama notes that conventional truck tires have taller sidewalls, while low-profile tires have shorter sidewalls and a lower overall height. On the road, that usually means the low-profile tire changes ride height and can affect gearing, clearance, and payload setup.
Common Conventional 22.5 Sizes
11R22.5 and 12R22.5 are old-school sizes with taller sidewalls. Fleets still keep them in service when the truck, wheel stock, and ride height were built around that casing shape.
10R22.5 shows up less often, but it hasn’t vanished. On older medium-duty trucks, it can still be the size on the placard, which is why guessing a replacement by eye is a risky move.
Common Metric 22.5 Sizes
Low-profile metric tires include 275/80R22.5, 295/75R22.5, 295/80R22.5, 305/70R22.5, and 315/80R22.5. They all fit 22.5-inch wheels, but their widths and outside diameters are not the same.
That’s why a lower second number does not mean a smaller tire in every direction. A 305/70R22.5 is wider than a 275/80R22.5, while the shorter sidewall changes the final outside height.
Where Wide-Base 22.5 Tires Fit In
Wide-base 22.5-inch tires sit in their own lane. A size like 385/65R22.5 is usually chosen for a single-tire setup, so it brings its own wheel and clearance rules.
There’s a pattern to the list. Conventional sizes keep the older section-width style. Metric sizes show width and sidewall ratio. Wide-base sizes stand apart because they change the wheel-end setup more than a simple same-family replacement would. Use the chart as a sorting tool, not as final fit approval. That one habit cuts bad swaps before they start and helps you ask sharper fit questions.
22.5 Inch Truck Tire Size Chart By Size Family
The chart below groups the most common 22.5-inch commercial sizes you’ll run across in North America. It’s built to help you sort the size before you move on to the maker’s load and fitment data.
| Size | Type | Where You Commonly See It |
|---|---|---|
| 10R22.5 | Conventional | Older medium-duty trucks, steer or all-position setups |
| 11R22.5 | Conventional | Common on regional tractors, straight trucks, and buses |
| 12R22.5 | Conventional | Heavier vocational or older heavy-duty applications |
| 255/70R22.5 | Metric low-profile | Medium-duty steer and all-position work |
| 275/70R22.5 | Metric low-profile | Regional steer, drive, or trailer fitments |
| 275/80R22.5 | Metric low-profile | A common all-position size on tractors and trucks |
| 295/60R22.5 | Metric low-profile | Lower-height fitments where deck height matters |
| 295/75R22.5 | Metric low-profile | One of the most common linehaul and regional sizes |
| 295/80R22.5 | Metric low-profile | Taller heavy-duty fitments with strong load capability |
| 305/70R22.5 | Metric low-profile | Steer and regional work where extra capacity is needed |
| 315/80R22.5 | Metric low-profile | Heavy steer, all-position, and severe-service jobs |
| 385/65R22.5 | Wide-base | Wide single steer or trailer applications |

What The Size Chart Does Not Tell You
A chart gets you in the ballpark. It does not approve a swap. Two tires that seem close on paper can still clash with the truck’s wheel width, brake package, fender room, or dual spacing.
Load Rating Comes First
If you haul more weight than the tire, wheel, or axle rating allows, the size is wrong even if the tire physically fits. That’s why you need the service description, load index or load range, and the inflation table for that exact tire model.
On 22.5-inch tires, the same size family can show up with different load capability by build and use.
Single And Dual Use Change The Math
This catches a lot of buyers. The same tire may carry one load as a single and a lower load in dual setup. That gap shows up in official tables, so you should never assume the sidewall number stays the same in both positions.
Axle Position Still Matters
Steer, drive, trailer, and all-position tires are built for different work. You can’t pick from a chart by size alone and call it done. Tread design, casing build, scrub resistance, and heat pattern all change with the job.
| Check Before You Swap | Why It Matters | What To Compare |
|---|---|---|
| Rim diameter | Both tire and wheel must be 22.5 | Sidewall size and wheel stamp |
| Section width | Affects wheel fit and sidewall clearance | Maker spec sheet |
| Overall diameter | Changes gearing, speed reading, and ride height | Published outside diameter |
| Single or dual use | Load limits differ by setup | Inflation table |
| Load index or range | Must match the axle job | Sidewall and spec book |
| Wheel width | Some sizes need a wider approved wheel | Tire maker fitment data |
| Dual spacing | Prevents tire rub and heat build-up | Truck and tire specs |
| Axle position | Steer, drive, and trailer jobs are not the same | Vehicle setup and tire application |
How To Read The Sidewall Before You Buy
Start with the full size code. Then read the service description right after it. That part tells you how much weight the tire is rated to carry and the speed category attached to that build.
Yokohama’s service description page points out that tire load capacity has to match axle capacity and total loaded vehicle weight, and that you should not exceed the tire, wheel, GAWR, or GVWR limits.
A Simple Reading Order
- Read the size.
- Read the service description or load range on the same sidewall.
- Match the tire to the axle position.
- Check approved wheel width, outside diameter, and inflation data for that exact model.
One Last Fit Check
If the truck runs duals, both tires on the axle need the same size designation and near-matching outside diameter. Mixing near-miss sizes is a bad bet. It can overload one tire, speed up wear, and build extra heat.
Mistakes That Cause Bad 22.5 Swaps
Most wrong orders start with one shortcut: matching rim diameter and stopping there. Yes, the tire must be 22.5. No, that does not make every 22.5 size a valid substitute.
- Buying by width alone. A 295 is not “close enough” to every other size in the same zone.
- Ignoring wheel width. Some heavier 22.5 sizes need a wider approved wheel than the one already on the truck.
- Replacing one dual with a near match. Close is not good enough on a dual assembly.
- Skipping the placard and axle ratings. A tire can be big enough to mount and still be wrong for the load.
The clean way to buy is simple: read the sidewall, check the placard, confirm wheel size and width, then pull the maker’s data for the exact tire model.
Choosing The Right 22.5 Size Without Guesswork
If you’re replacing one damaged tire on a truck that already wears the correct size, the safest move is usually to match the exact size, load rating, and application already approved for that axle. This chart helps you sort the family fast, then the maker’s spec sheet does the final job.
