295/70R17 Tire Size

All You Need to Know About 295/70R17 Tires

295/70R17 tires are 295 mm wide, with a 70% aspect ratio and a 17-inch wheel diameter, resulting in an overall diameter of ≈33.3 inches and a sidewall height of ≈8.1 inches. The approved rim width range typically falls between 7.5 and 10.0 inches.

This page focuses on the dimensional behavior of 295/70R17 and how its large diameter and wide section affect clearance, gearing, and footprint. For load-carrying construction and pressure-related behavior, see LT295/70R17 tires.

At ≈8.1 inches, the sidewall of 295/70R17 operates in a high-deflection range where deformation is part of how the tire works. That sidewall depth helps the tire absorb surface irregularities and maintain contact on broken terrain, while the 295 mm section width increases footprint and lateral support compared with narrower 70-series alternatives.

295/70R17 Size Quick Specs

• Approved rim width range: 7.5"–10.0"
• Optimal rim width: 8.5"-9.0"
• Width: 295 mm
• Sidewall height: 206.5 mm
• Overall diameter: ≈33.3"
• Wheel diameter: 17"

Note: The 295/70R17 calculated overall diameter is ≈33.3 inches. Small variation by manufacturer is normal because tread depth and casing design can shift the published diameter slightly.

295/70R17 Common Vehicle Fitment

295/70R17 is most commonly seen on lifted or reworked truck and SUV setups where a wider footprint and roughly 33-inch diameter are used to increase ground clearance and off-road traction over smaller stock fitments. Common platforms used as a base for these builds include:

• Ford F-150
• Chevrolet Silverado 1500 / GMC Sierra 1500
• Ram 1500
• Toyota Tundra
• Toyota 4Runner and Tacoma
• Jeep Wrangler (17-inch wheel configurations)

295/70R17 fitment depends heavily on vehicle generation, trim, and whether a lift has been installed. None of these platforms accepts 295/70R17 on a stock suspension without clearance verification.

At ≈33.3 inches in diameter and ≈11.6 inches in section width, 295/70R17 is not a neutral size change on most stock vehicles. Fender clearance, inner suspension clearance, steering lock clearance, and compression travel all need to be verified before installation.

295/70R17 Dimensions in Inches

The 295/70R17 measures approximately 11.6 inches in width, 33.3 inches in overall diameter, and 8.1 inches in sidewall height.

That combination places 295/70R17 in the tall, wide light-truck category. The wider section broadens the contact patch shape and increases the lateral footprint, while inflation pressure and load remain the primary drivers of total contact area. The taller diameter reduces wheel rotation frequency relative to common factory light-truck fitments on the same 17-inch wheel — such as 265/70R17, 275/70R17, or 285/70R17 - meaning the vehicle travels farther per revolution, which affects effective gearing, speedometer accuracy, and clearance requirements simultaneously.

295/70R17 in Inches: Full Measurement Set

• Overall diameter: ≈33.3"
• Width: ≈11.61"
• Sidewall height: ≈8.13"
• Wheel diameter: 17"
• Circumference: ≈104.49"

Comparison of 295/70R17 With Similar Tire Sizes

295/70R17 is often compared with 285/70R17, which stays close in diameter while reducing width, and 295/75R17, which keeps the same width but moves into a taller diameter class. The first comparison stays within the accepted substitution range; the second exceeds it.

295/70R17 vs 285/70R17

• Width: 295/70R17 is 10 mm wider
• Overall diameter: 295/70R17 is ≈0.55 inches (≈1.66%) larger than 285/70R17

At ≈1.66%, the diameter gap remains within the ±3% threshold. From a drivetrain and speedometer standpoint, this is one of the cleaner substitutions in the 17-inch truck category. The practical difference is width: the extra 10 mm of the 295/70R17 size increases section width and footprint, so inner clearance, outer clearance, and rim width compatibility need to be confirmed.

295/70R17 vs 295/75R17

• Width: identical at 295 mm
• Overall diameter: 295/75R17 is ≈1.16 inches (≈3.49%) larger than 295/70R17

At ≈3.49%, the difference exceeds the ±3% threshold, which places these sizes outside the direct substitution range. The taller 295/75R17 raises effective ride height, lowers rotational frequency, and creates measurable speedometer under-reading and gearing change. Even though the width does not change, the diameter increase alone is enough to make clearance and calibration verification necessary.

Before changing tire size from or to 295/70R17, review how the 3% rule applies and what additional fitment checks still need to be made after the diameter is confirmed.
