The 225/50R17 gives a slightly softer ride due to the taller sidewall. If your car came with 225/45R17, fitting 225/50R17 will cause your speedometer to read ~4% low.

35 Inch Tire Size Chart

35-inch tires are a popular upgrade for Jeep Wranglers, Ford Broncos, and full-size trucks. Most require a 2.5โ€“3.5" lift. Common metric equivalents:

True 35x12.50 flotation sizes are the most common choice. Metric equivalents vary slightly in actual diameter.

285/75R16 Dimensions

A classic truck and off-road size, common on older Ford F-150s, Chevy Silverados, and Jeep XJs. Often called a "32-inch tire."

The 285/75R16 fits most stock 16" rims with 7โ€“8.5" width. It typically clears without a lift on body-on-frame trucks but may require minor trimming on some SUVs.

265/70R17 Overall Height & Dimensions

A popular OEM and mild off-road size on trucks and SUVs (Toyota Tundra, Chevy Colorado, GMC Canyon). Often used as a base before upgrading to 33s.

Upgrading from 265/70R17 to 285/70R17 adds about 0.8" in diameter โ€” a common mild lift upgrade that usually fits without rubbing on most trucks.

How to Use This Tire Size Chart

Three simple steps to read, compare, and choose the right tire dimensions for your vehicle.

Read a Tire Size

Find the code on your tire sidewall, e.g. '265/70R17'. The first number is width in mm, the middle is aspect ratio (%), and the last is rim diameter in inches.

Compare Tire Diameter

Use the Diameter column to compare overall height between two tire sizes side by side. A 265/70R17 is approx 31.6" โ€” a key number for lift kit and speedometer checks.

Check Clearance Before You Buy

Cross-reference the Width column to check for control arm or fender liner clearance. Wider tires give better grip but may rub at full steering lock.

Common Applications

๐Ÿš™

Off-Road & Overlanding

Moving from a stock 30" tire to a 33" or 35" increases ground clearance but may require a lift kit.

  • โ€ขCommon upgrades: 33s (285/70R17)
  • โ€ขExtreme: 35s (315/70R17) or 37s
  • โ€ขCheck clearance at full flex
๐ŸŽ๏ธ

Performance & Stance

Plus-sizing wheels (e.g., 18" to 19") requires a lower profile tire to maintain the same overall diameter.

  • โ€ขMaintain speedometer accuracy
  • โ€ขLow profile = better cornering
  • โ€ขWatch for pothole damage
๐Ÿš›

Trucks & Towing

Load range and sidewall stiffness matter. A 'metric' size might have different load ratings than an LT (Light Truck) size.

  • โ€ขLT sizes usually have deeper tread
  • โ€ขCheck Load Index (e.g. 121/118)
  • โ€ขE-Load for heavy towing

Metric vs. Flotation Sizes

Metric (e.g., 285/75R16)

Standard for most modern vehicles. Format: [Width mm] / [Aspect Ratio %] R [Rim Diameter]. Requires calculation to find height.

Flotation (e.g., 33x12.50R15)

Common for older trucks and off-road tires. Format: [Height in] x [Width in] R [Rim Diameter]. Dimensions are explicit, no math needed.

Frequently Asked Questions About Tire Sizes

What does 225/45R17 mean?

225 is the tire width in millimeters. 45 is the aspect ratio โ€” the sidewall height is 45% of 225mm. R means Radial construction. 17 is the rim diameter in inches. So a 225/45R17 tire is 225mm wide, sits on a 17-inch wheel, and has a sidewall height of about 101mm (roughly 4 inches).

How do I compare tire sizes?

To compare two tire sizes, look at the overall diameter column in this chart. For example, a 225/45R17 has a diameter of about 24.9 inches while a 225/50R17 is about 25.9 inches โ€” a 1-inch difference that affects clearance, speedometer reading, and handling. Use the chart above to compare any two sizes side by side.

How much taller is one tire size than another?

You can calculate the difference using the formula: overall diameter = (width ร— aspect ratio / 1270) + rim size. For instance, 235/65R17 has a diameter of 29.0 inches vs. 225/65R17 at 28.5 inches โ€” a 0.5-inch height difference. Our tire size chart shows pre-calculated diameters so you don't need to do the math.

Can I print this tire size chart?

Yes. Use the Download or Print button above the chart to save a PDF or PNG version. The printable format is designed for garage walls, workshops, or shop counters โ€” easy to read at a glance without needing a screen.

What is the actual diameter of a 225/80R16 tire?

A 225/80R16 tire has an actual overall diameter of approximately 30.2 inches. It has a section width of 8.9 inches and a sidewall height of 7.1 inches.

Does changing tire size affect my speedometer?

Yes. Taller tires cover more ground per revolution, making your speedometer read slower than your actual speed. This can lead to speeding tickets if not recalibrated via a tuner or gear change.
