How Tall Is a 265 70 R17 Tire? Exact Height, Width & Dimensions
A 265/70R17 tire is a popular truck and SUV size that measures about 31.6 inches tall, 10.4 inches wide, and 7.3 inches from rim to tread on each sidewall. Those numbers make it useful for comparing clearance, gearing, wheel fitment, and tire choices before you buy.
Quick Answer
A 265/70R17 tire is about 31.6 inches tall, 10.4 inches wide, and has a 7.3-inch sidewall. Its circumference is about 99.2 inches, with roughly 638 revolutions per mile. It fits a 17-inch wheel, but exact fitment depends on rim width, load rating, offset, suspension clearance, and your vehicle’s tire placard.
Key Takeaways
- A 265/70R17 tire is about 31.6 inches tall, or about 80.3 cm in overall diameter.
- The section width is 265 mm, which equals about 10.4 inches.
- The sidewall height is 185.5 mm, or about 7.3 inches, because the aspect ratio is 70% of 265 mm.
- Most 265/70R17 passenger versions use a 7- to 9-inch rim range; many LT versions list a narrower 7- to 8.5-inch range, so check the tire maker’s spec sheet.
- Before changing to this size, verify clearance, load index, speed rating, tire pressure, and speedometer change against your vehicle placard and owner’s manual.

What Is the Height of a 265/70R17 Tire?
A 265/70R17 tire is approximately 31.6 inches tall, or 802.8 mm, when calculated from the standard metric tire-size formula. You get that number by doubling the sidewall height and adding the 17-inch wheel diameter.
Here is the math:
- Sidewall height: 265 mm × 0.70 = 185.5 mm
- Wheel diameter: 17 in × 25.4 = 431.8 mm
- Overall diameter: 185.5 mm + 431.8 mm + 185.5 mm = 802.8 mm
- Overall diameter in inches: 802.8 mm ÷ 25.4 = 31.6 in
Note: Published tire dimensions are nominal. Real mounted height can vary slightly by brand, tread depth, load, inflation pressure, measuring rim width, and whether the tire is P-metric, SL, XL, or LT.
How Wide Is a 265/70R17 Tire?
The 265/70R17 tire is about 10.43 inches wide, based on its 265 mm section width. Section width is the tire’s nominal sidewall-to-sidewall width, not the tread width. Tread width is usually narrower and varies by tire model and tread design.
| Measure | Metric | Imperial |
|---|---|---|
| Section width | 265 mm | 10.43 in |
| Sidewall height | 185.5 mm | 7.30 in |
| Overall diameter | 802.8 mm | 31.6 in |
| Circumference | about 2,522 mm | about 99.2 in |
| Revolutions per mile | about 396.5 rev/km | about 638 rev/mile |
What Rim Width Fits a 265/70R17 Tire?
A 265/70R17 tire fits a 17-inch wheel. The common approved rim-width range is usually 7 to 9 inches for many passenger/SUV versions, while many LT265/70R17 tires list 7 to 8.5 inches. Because rim approval can vary by tire line, always confirm the specific tire manufacturer’s spec sheet before mounting.
Warning: Do not choose a replacement tire by size alone. Match or exceed the load index and speed rating listed on your vehicle placard or owner’s manual, and use the vehicle manufacturer’s recommended cold tire pressure rather than the maximum pressure molded on the tire sidewall.
How Does 265/70R17 Affect Ride and Clearance?
With a 31.6-inch diameter, a 265/70R17 tire can increase ground clearance if it replaces a smaller tire. The actual gain is half the diameter difference, because only the radius raises the axle and body. For example, moving from a 30.6-inch tire to a 31.6-inch tire adds about 0.5 inch of ground clearance before real-world compression and tread-wear differences.
The taller 7.3-inch sidewall can also improve impact absorption compared with a lower-profile tire. That can help ride comfort on rough roads, gravel, and trails. The tradeoff is that a taller, heavier tire may slightly dull steering response, add rotational weight, reduce fuel economy, and change effective gearing.
Speedometer change matters too. If the new tire has a larger diameter than your original tire, your vehicle may travel faster than the indicated speed. The percent change is:
New tire diameter ÷ old tire diameter − 1 = speedometer difference
For example, changing from a 255/65R17 tire at about 30.1 inches tall to a 265/70R17 at about 31.6 inches tall is roughly a 5.2% increase. When the speedometer shows 60 mph, actual speed may be about 63 mph unless the vehicle is recalibrated.
Pro Tip: Before buying, turn the steering wheel fully left and right, check front and rear fender clearance, inspect upper control arm clearance, and confirm the spare tire location can hold the same overall diameter.
What Vehicles Fit 265/70R17 Tires?
265/70R17 tires are common on trucks, body-on-frame SUVs, off-road builds, and light-duty haulers that use 17-inch wheels. You may see this size on certain trims or model years of vehicles such as the Chevrolet Silverado 1500, Ford F-150, Jeep Wrangler, Toyota 4Runner, Toyota Tacoma, GMC Sierra, Nissan Frontier, and similar truck/SUV platforms. Fitment is not universal, so treat vehicle examples as a starting point, not a guarantee.
Use this checklist before mounting 265/70R17 tires:
- Door placard: Check the original tire size, cold pressure, load rating, and speed rating.
- Owner’s manual: Confirm approved tire and wheel sizes for your trim.
- Wheel width: Verify that your 17-inch wheel falls inside the tire maker’s approved rim-width range.
- Wheel offset: Check inner clearance to control arms, sway bars, brake lines, and fender liners.
- Suspension height: Stock, leveled, and lifted vehicles can have different clearance limits.
- Rubbing: Test full steering lock, compression, reverse, and driveway angles.
- Spare tire: Make sure the spare location fits a tire close to the same diameter.
- Electronics: Large diameter changes may affect ABS, stability control, TPMS behavior, gearing, and speedometer accuracy.

Which 265/70R17 Tires Are Best for You?
The best 265/70R17 tire depends on how you drive, how much weight you carry, and what weather you face. Start with the required load index and speed rating, then choose the tread type.
- Highway and daily driving: Choose a highway-terrain or touring all-season tire if quiet ride, wet braking, comfort, and tread life matter most. The Pirelli Scorpion All Season Plus 3 is one example of a touring all-season option sold in 265/70R17.
- Mixed road and trail use: Choose an all-terrain tire if you split time between pavement, gravel, dirt, snow, and light trails. The Falken Wildpeak A/T4W is one current all-terrain example with severe-snow rating and mileage warranty coverage listed by Falken.
- Mud and harsher trails: Choose a mud-terrain tire only if you need deeper voids and stronger trail bite. Expect more road noise, more weight, and usually shorter tread life on pavement.
- Towing or payload: Consider LT-rated versions only when your vehicle and use case call for the added load capability. LT tires can ride firmer and may require different inflation pressures.
