295 75r 22.5 Vs 11r22 5

You’re standing at the tire counter, invoice in hand, and the guy behind the desk asks a question that stops you cold: “295/75R22.5 or 11R22.5?

If you’ve been around trucks long enough, you know both sizes fit a 22.5-inch wheel. You know they’re both standard workhorses for Class 8 tractors and heavy vocational trucks. But the differences? That’s where the expensive mistakes happen.

Let’s sort this out once and for all.

What Is the Actual Difference

At a glance, these tires look almost identical mounted on the truck. So both run on 22. 5-inch rims. That said, both are radials (that’s the “R”). Both carry heavy loads day in, day out.

But the numbers tell a different story.

Breaking Down the Metric Size: 295/75R22.5

At its core, a metric designation. Here’s how to read it:

• 295 — Section width in millimeters. That’s the widest point of the sidewall-to-sidewall measurement.
• 75 — Aspect ratio. The sidewall height is 75% of that 295 mm width. Do the math: roughly 221 mm tall sidewall.
• R — Radial construction.
• 22.5 — Rim diameter in inches.

Overall diameter usually lands around 39.9 to 40.2 inches depending on the manufacturer and tread depth. Revolutions per mile? Typically 516 to 520.

Breaking Down the Numeric Size: 11R22.5

This is the older, inch-based nomenclature still used heavily in North America:

• 11 — Nominal section width in inches.
• R — Radial.
• 22.5 — Rim diameter in inches.

No aspect ratio listed because it’s baked into the standard — roughly 88% for this series. That gives a taller sidewall relative to width. Overall diameter runs 41.1 to 41.5 inches. Revolutions per mile drop to 495 to 501.

The Short Version

The 11R22.5 is taller and narrower. The 295/75R22.5 is shorter and wider. That single sentence explains 80% of what you need to know for fitment, gearing, and ride.

Why It Matters / Why People Care

You might think a half-inch in diameter or 20 mm in width is splitting hairs. On a grocery getter, maybe. On an 80,000-lb combination vehicle running 120,000 miles a year? It changes everything.

Gearing and Speedometer Accuracy

Basically the big one nobody thinks about until the ECM throws a code or the speedometer reads 62 mph at a true 65.

Swapping from 11R22.5 to 295/75R22.5 increases revolutions per mile by roughly 3–4%. Plus, the engine spins faster at a given road speed. Fuel economy takes a hit — usually 0.In real terms, 2 to 0. 4 mpg depending on your rear axle ratio and cruise speed. The speedometer reads fast. The odometer accumulates miles quicker, which messes with maintenance intervals and resale value.

Go the other way — 295/75R22.5 to 11R22.5 — and you lose RPM. Now, the engine lugs lower in its sweet spot at highway speed. Great for fuel, bad if you’re already geared tall and struggle on grades.

Real talk: If you’re spec’ing a new truck, the dealer should match the tire to the rear axle ratio and intended cruise speed. If you’re just replacing tires on an existing rig, stick with what the truck came with unless you’re deliberately re-gearing.

Frame Clearance and Suspension Travel

The 11R22.Which means 5 stands roughly 1 to 1. 5 inches taller. On a tractor with air ride suspension aired up, that’s usually fine. But drop the bags for loading dock alignment, or run a vocational truck with heavy spring packs, and that extra radius eats into frame clearance.

I’ve seen fleets spec 11R22.Expensive lesson. The 295/75R22.Plus, 5 on dump trucks only to have the tires kiss the frame rails on full compression. 5 buys you that extra inch of buffer.

Conversely, the 295/75R22.Because of that, 5 is wider. On tight turning radii — think city tractors with set-forward front axles — the wider tread can scrub the leaf springs or the steering stops at full lock. Check your turning clearance before you swap.

Load Capacity and Ply Ratings

Here’s where the spec sheets get sticky.

Continue exploring with our guides on 17 of 25 is what percent and what has a bottom on the top.

Both sizes are available in Load Range G (14-ply) and Load Range H (16-ply). And at equal load range, the 11R22. 5 typically carries 100–200 lbs more per tire at the same inflation pressure because the larger air volume supports more weight.

Example: A common LRH 11R22.A comparable LRH 295/75R22.5 rates 6,610 lbs single / 6,005 lbs dual at 120 psi. 5 often rates 6,175 lbs single / 5,675 lbs dual at 120 psi.

If you’re running heavy haul or maxed-out gross weights, that difference matters. It might be the gap between legal and overweight on a steer axle.

But — and this is critical — load range trumps size. A Load Range H 295/75R22.Which means 5 out-carries a Load Range G 11R22. 5 every time. Don’t compare sizes without comparing ply ratings.

Traction and Footprint

Wider tire, wider contact patch. On the flip side, the 295/75R22. 5 puts more rubber on the ground laterally. That helps lateral stability in crosswinds and improves flotation on soft shoulders or unpaved yards.

The 11R22.5’s narrower, longer footprint concentrates weight per square inch. That’s actually better for cutting through snow to find pavement, and it reduces rolling resistance slightly — hence the fuel economy edge.

Neither is “better.” They’re tools for different jobs.

How to Choose (or How to Spec)

Don’t guess. Follow this decision tree.

Step 1: Check the Door Placard

Every truck leaves the factory with a tire placard on the driver’s door jamb or B-pillar. It lists the OE size, load range, and cold inflation pressure. That is your baseline. Deviate only with a reason.

Step 2: Match the Application

Step 3: Validate Clearances

Before mounting anything, do a mock-up. Raise the axle, cycle the suspension through full compression and droop, and turn the wheels to full lock. Measure from the tire sidewall to every potential contact point: frame rails, leaf springs, steering stops, brake components, and fender wells.

The 295/75R22.Because of that, 5’s extra width demands at least 1. 5 inches of clearance on each side. And the 11R22. 5’s taller profile needs adequate vertical spacing — typically 2 inches minimum from tread to any obstruction.

Step 4: Verify Load Requirements

Calculate your actual axle loads. If your steer axle runs 12,000 lbs loaded and you’re on a 11R22.5 rated 6,610 lbs per tire, you’re at 90% of capacity — acceptable. Practically speaking, if you switch to a 295/75R22. 5 rated 6,175 lbs, you’re now at 97% — dangerously close to the limit.

Use the manufacturer’s load/inflation charts religiously. Never assume.

Step 5: Consider Fleet Standardization

If you operate multiple trucks, weigh the benefits of mixing sizes against inventory complexity. Running one size across your fleet simplifies purchasing, reduces spare tire inventory, and trains technicians on a single service protocol.

Even so, if your fleet operates diverse applications (long-haul tractors plus city dump trucks), standardizing on one size may hurt performance where it counts.

The Bottom Line

There is no universal “best” tire size for 22.5-inch wheels. 5 excels in load capacity, fuel economy, and durability for long-haul and vocational applications. So naturally, the 11R22. The 295/75R22.5 offers superior turning clearance, lateral stability, and ride comfort for regional and urban operations.

Choose based on your specific operational demands, not marketing claims or what the truck down the road is running. Verify clearances, match load requirements, and always consult the original equipment specifications.

When in doubt, consult a tire specialist who understands your application. The right tire choice pays dividends in uptime, fuel costs, and driver satisfaction. The wrong choice costs far more than the price difference on the tire itself.

Your truck, your load, your decision — make it informed.
