What “215/60R16” Means on a Tire

It denotes the tire’s size and construction: 215 is the section width in millimeters, 60 is the aspect ratio (sidewall height equals 60% of the width), R indicates radial construction, and 16 is the wheel diameter in inches the tire fits. This code determines fitment, ride characteristics, and performance, and is usually followed by a load index and speed rating (for example, 95H).

Decoding the numbers and letter

The characters in 215/60R16 each describe a different physical feature of the tire. Here’s how to read them accurately to understand what will fit your vehicle and how it may perform.

• 215 — Section width: the tire’s width at its widest point, in millimeters (about 8.46 inches). Actual width can vary slightly by brand and by rim width.
• 60 — Aspect ratio: sidewall height expressed as a percentage of the width. Here, 60% of 215 mm = 129 mm.
• R — Radial construction: the internal plies run radially across the tire. This is standard for modern passenger tires.
• 16 — Wheel diameter: the tire mounts on a 16-inch wheel (rim) only.

Together, these elements define the tire’s basic size and construction. Additional markings after the size specify load capacity and maximum sustained speed, plus other service information.

What this size means for fit, ride, and performance

Beyond basic dimensions, 215/60R16 has practical implications for how your vehicle feels and behaves. Consider these factors before changing sizes.

• Ride comfort: a 60-series sidewall provides more cushion than low-profile sizes, helping absorb bumps and potholes.
• Handling: taller sidewalls flex more, which can soften steering response compared with lower aspect ratios, but often improve comfort.
• Wheel protection: more sidewall helps protect the rim against curb rash and pothole impacts.
• Clearance and calibration: overall diameter must clear fenders, struts, and brake components; large changes affect ABS/traction control and speedometer accuracy.

Staying close to your vehicle’s original overall diameter (typically within about ±3%) helps maintain proper clearances and accurate speedometer readings.

How to calculate key dimensions from 215/60R16

You can estimate overall size and its impact on gearing and speedometer by calculating a few basics from the code.

1. Sidewall height: 215 mm × 0.60 = 129 mm (≈ 5.08 in).
2. Wheel diameter: 16 in (406.4 mm).
3. Overall diameter: (2 × 129 mm) + 406.4 mm = 664.4 mm (≈ 26.16 in).
4. Circumference: 26.16 in × π ≈ 82.2 in (≈ 2.09 m).
5. Revolutions per mile: 63,360 in ÷ 82.2 in ≈ 771 rev/mi.

Actual measured values vary by tire model due to tread design, manufacturing tolerances, rim width, inflation, and load. Always check the manufacturer’s specifications for the exact tire you’re considering.

Other markings you’ll see near 215/60R16

The size code is just one part of the sidewall story. These additional markings are essential for selecting a safe, compliant tire.

• Load index (e.g., 95): indicates maximum load per tire (95 ≈ 1521 lb/690 kg). Always meet or exceed your vehicle’s placard rating.
• Speed rating (e.g., H): maximum certified speed (T=118 mph/190 km/h, H=130 mph/210 km/h, V=149 mph/240 km/h, W=168 mph/270 km/h, Y=186 mph/300 km/h).
• Service type: P (Passenger), LT (Light Truck), XL/EL (Extra Load), or no prefix (Euro-metric).
• Seasonal markings: M+S (mud and snow), 3PMSF mountain-snowflake (severe-snow certified).
• UTQG: treadwear/traction/temperature grades for passenger tires in the U.S.
• DOT/date code: four digits indicating week and year of manufacture (e.g., 3222 = week 32 of 2022).

Match or exceed both the load index and speed rating specified on your vehicle’s door-jamb placard. Many tire makers advise professional inspection from five years of age and replacement by ten years, regardless of tread, but follow the tire and vehicle manufacturer’s guidance.

Common alternate sizes and interchange considerations

If you’re exploring replacements, some sizes are close in rolling diameter to 215/60R16 and may work depending on your vehicle and wheels. Always verify fitment and load/speed ratings.

• 205/65R16 — ≈ 26.50 in diameter (+1.3%).
• 225/55R16 — ≈ 25.75 in diameter (−1.6%).
• 215/55R17 — ≈ 26.31 in diameter (+0.6%) if “plus-sizing” to 17-inch wheels.
• 225/50R17 — ≈ 25.86 in diameter (−1.1%) on 17-inch wheels.

Before switching sizes, confirm wheel width compatibility (a typical 215-width tire fits roughly 6.0–7.5 in rims, depending on the model), fender/brake clearance, load index, speed rating, and speedometer error. Consult a professional or a trusted fitment guide.

Where to find the recommended size for your vehicle

To ensure safety and performance, start with the size your vehicle manufacturer specifies. You can find it in several places.

• Driver’s door-jamb tire and loading placard (most reliable).
• Owner’s manual.
• Fuel-filler door or glovebox placard (on some models).
• OEM service information or the manufacturer’s website.

Use the placard size and ratings as your baseline; any change should maintain or exceed the original load and speed specifications and stay close in overall diameter.

Summary

“215/60R16” identifies a radial tire that’s approximately 215 mm wide, has a sidewall 60% as tall as its width, and mounts on a 16-inch wheel. This size balances comfort and protection with reasonable handling, and it’s common on many passenger cars and small crossovers. Always pair the size with the correct load index and speed rating, check the exact measured specs from the tire maker, and verify fitment against your vehicle’s placard before buying.

What’s the difference between 215 60R16 and 225 60R16?

The primary difference is that a 225/60R16 tire is wider than a 215/60R16 tire, resulting in better traction and handling, a slightly larger overall diameter, and potentially reduced fuel economy and slower acceleration compared to the narrower 215/60R16. While the 225/60R16 is generally a safe alternative, always verify it fits your specific vehicle’s clearances and consult your owner’s manual or doorjamb sticker before switching to a different size. 
Key Differences

• Width: The “225” in 225/60R16 indicates the tire’s section width is 225 millimeters, while the “215” in 215/60R16 is 215 millimeters. 
• Contact Patch: The wider 225 tire has a larger contact area with the road, which can improve traction, especially in dry conditions. 
• Overall Diameter: The 225/60R16 has a slightly larger overall diameter (26.6 inches compared to 25.2 inches for the 215/60R16). 
• Sidewall Height: The sidewall of the 225 tire is also slightly taller. 

Performance Implications

• Handling & Stability: The wider 225 tire can offer sportier handling, enhanced cornering, and improved stability due to its wider footprint. 
• Ride Comfort: Both sizes have a high aspect ratio, which contributes to a comfortable, cushioned ride by absorbing road imperfections. 
• Fuel Economy & Acceleration: The increased width and diameter of the 225 tire can lead to a slight reduction in fuel economy and slightly slower acceleration. 
• Speedometer Accuracy: A slightly larger overall diameter on the 225 tire will cause the speedometer to read slightly low. 

Important Considerations

• Vehicle Clearance: Always check the tire manufacturer’s recommendations and your vehicle’s clearances to ensure the wider tire will not come into contact with wheel components. 
• Consistency: If you change tire sizes, it is best to do so for all four tires or at least a pair on the same axle. 
• Manual & Stickers: Consult your vehicle’s owner’s manual or the doorjamb sticker for the manufacturer-recommended tire size. 

Are 215-60 R16 tires good for winter?

They provide great traction and durability for the winter season! They make a front wheel drive car a usable vehicle during the winter months.

What tire size is a 215 60R16?

215/60R16 tires have a diameter of 26.1″ (664 mm), a tread width of 8.5″ (215 mm), and a wheel diameter of 16″ (406.4 mm). The sidewall of the tire is 5.1″ (129 mm), and the tire’s circumference is 82″ (2085 mm).

What does 60R mean on a tire?

On a tire, 60R indicates a tire’s “aspect ratio” and “construction method”. The 60 is the aspect ratio, a percentage representing the tire’s sidewall height in relation to its width. The R signifies the tire’s internal construction, meaning it is a radial tire. 
Here’s a breakdown of what this means in a typical tire size, like P205/60R15: 

• P: Indicates a “Passenger” vehicle tire. 
• 205: The tire’s section width in millimeters. 
• 60: The aspect ratio, meaning the sidewall height is 60% of the 205mm width. 
• R: Radial construction, the most common type, where internal ply cords run perpendicular to the direction of rotation. 
• 15: The diameter of the wheel rim in inches that the tire fits.
