Are 11R22.5 Tires The Same As 295/75R22.5? | Size Match Facts

No, the two truck tire sizes sit close on paper, but their width, sidewall shape, air pressure, and dual-load specs are not identical.

If you’re asking whether Are 11R22.5 Tires The Same As 295/75R22.5?, the clean answer is no. They’re close enough that people often mention them in the same breath, and some fleets move between them depending on axle position, brand, and casing strategy. Still, “close” is not the same as “the same,” and that difference matters once you get into clearance, inflation, and load rating.

That’s why this swap gets people tripped up. Both sizes fit a 22.5-inch wheel. Both show up on commercial trucks. Both can carry similar single-tire loads in many common specs. Then you look at real manufacturer data and see the catch: one is usually a little taller, one can be a touch wider depending on the design, and the pressure tied to the rated load may not match.

So, if you’re buying replacements, matching a mate in a dual setup, or trying to keep ride height steady across an axle, treat them as near-equivalents, not twins.

11R22.5 Vs 295/75R22.5 In Real-World Fitment

The naming format tells part of the story. An 11R22.5 uses the older inch-based style. A 295/75R22.5 uses the metric style, where 295 is section width in millimeters and 75 is the aspect ratio. That alone tells you the tires are being described from two different sizing systems.

Bridgestone’s truck tire size material places 295/75R22.5 and 11R22.5 side by side as closely related commercial sizes, not as one-to-one copies. It also lists them in different common roles: 295/75R22.5 shows up often in drive or trailer use, while 11R22.5 is often seen in steer or drive service. You can read that sizing overview in Bridgestone’s semi-truck tire size guide.

Once you move from the sidewall code to product sheets, the small gaps become easier to see. In several Bridgestone and Firestone examples, 11R22.5 tends to run a bit taller overall than 295/75R22.5. The metric size often lands a bit lower in overall diameter, which means a few more revolutions per mile and a slightly different loaded stance.

Those numbers aren’t cosmetic. A taller tire can change effective gearing, speed reading, fender gap, and the way a truck sits next to the tire beside it. On a steer axle, that may alter the look and feel of the truck. On a dual setup, it can change how evenly the pair shares the work.

Why People Call Them “Equivalent”

People call these sizes equivalent because they live in the same neighborhood. In many common load range G specs, each can carry 6,175 pounds in single service. That makes the swap sound harmless at first glance.

But even when single-load capacity lines up, the inflation needed to reach that load may differ. A common 295/75R22.5 spec reaches that load at 110 psi, while many 11R22.5 specs reach it at 105 psi. Dual ratings can also split, with 11R22.5 often carrying more in dual service than 295/75R22.5 in similar G-range examples.

That means equivalence is only partial. It works as a shorthand for “similar class,” not “same tire.”

What The Size Difference Looks Like On Paper

Below is a practical side-by-side summary built from common commercial tire specs. Exact measurements move a little by brand and tread pattern, so treat these as a working range, not a law carved in stone.

Specification Area	11R22.5	295/75R22.5
Size system	Inch-based commercial format	Metric commercial format
Wheel diameter	22.5 inches	22.5 inches
Typical overall diameter	About 41.1 to 42.2 inches	About 40.3 to 40.9 inches
Typical section width	About 11.2 to 11.6 inches	About 11.4 to 11.5 inches
Revolutions per mile	Usually fewer	Usually more
Single load in common G specs	Often 6,175 lbs	Often 6,175 lbs
Dual load in common G specs	Often 5,840 lbs	Often 5,675 lbs
Pressure tied to common single load	Often 105 psi	Often 110 psi
Usual takeaway	Near-match, not exact match	Near-match, not exact match

That table gets to the point fast: same wheel size, similar working class, different physical profile. So the swap question should never stop at “Will it mount?” It also needs “Will it match the truck, the mate, and the load plan?”

Where The Swap Works And Where It Can Go Wrong

Single-position replacement

If you’re replacing tires on an axle where all tires will be the same size, the move can work when the wheel width, load range, pressure, and clearance all line up with the manufacturer’s rating. Plenty of fleets spec one or the other based on availability, price, casing program, or axle role.

The danger shows up when someone assumes similar means automatic. A tire that is slightly shorter or slightly different under load can change stance and working pressure. That may not be dramatic on day one, yet it still affects wear, handling feel, and how evenly the truck carries the load over time.

Dual tires on the same axle

This is where you need to slow down. Mixing close-but-not-equal sizes in a dual assembly is a bad bet. If one tire has a different loaded radius, one tire can end up doing more of the work. That brings heat, scrub, and odd wear into the picture much sooner than most operators want.

Even when the unloaded tires look close in the yard, the loaded shape can tell a different story. A safer rule is simple: in a dual set, match size, model family, load range, and wear level as tightly as you can.

Steer axle use

On a steer axle, height and profile can affect the truck’s stance and the feel through the wheel. A size that runs taller may alter clearance near the fender or mud flap. A size that needs a different pressure for the same load can also change ride feel and footprint.

That does not mean one size is better across the board. It means the truck should be spec’d around the tire, not the other way around.

How To Decide Which Size You Actually Need

The cleanest way to choose is to start with the truck’s current placard, the axle role, and the load target. Then check the tire maker’s size book and load table before ordering. Bridgestone’s load and inflation tables make that check easy.

Here’s a simple way to work through it:

• Confirm the wheel is 22.5 inches and the approved rim width matches the tire you want.
• Check single and dual load ratings, not just the headline size.
• Match the pressure needed for your real axle weight.
• Measure clearance at the fender, frame, suspension, and between duals.
• Keep all tires on the same axle matched in size and load range.
• Use the truck maker’s spec when there’s any conflict.

A lot of costly tire mistakes happen because someone stops after step one. Mounting is only one part of fitment. The load table and the loaded dimensions do the heavy lifting in this decision.

If You Need	Better Choice To Check First	Reason
A direct match to the tires already on the truck	Same size already fitted	Keeps ride height, pressure target, and axle matching simple
A swap on a full axle set	Either size, after spec check	Uniform tires remove most pairing issues
A mate for an existing dual tire	Exact same size and model family	Reduces uneven load sharing and scrub
Maximum confidence on steer fit	Truck maker’s original size	Protects stance and clearance
Used-tire replacement	Exact same marked size	Avoids mixed-height surprises

The Straight Answer

11R22.5 and 295/75R22.5 are not the same tire size. They’re close substitutes in many fleet settings, and that’s why the question keeps coming up. Still, they do not share the exact same dimensions, the exact same pressure-to-load relationship, or the exact same dual-service rating in many common specs.

If you’re changing every tire on the axle and the truck’s fitment data supports the move, one may replace the other just fine. If you’re matching an existing tire, filling one spot in a dual pair, or trying to avoid any change in height or load setup, stick with the exact size already spec’d.

That’s the clean takeaway: close match, not same match.
