All You Need to Know About 255/80R17 Tires
255/80R17 tires have a section width of 255 millimeters (mm), an aspect ratio of 80%, radial construction, and a 17-inch wheel diameter. The 255/80R17 tire size has an overall diameter of 33.1 inches and fits within a 6.5’’-8.5’’ rim width range, making it a common fitment for off-road-focused light trucks and overland-style SUV builds (primarily aftermarket).
255/80R17 Size Quick Specs
- Overall diameter: 33.1 in
- Sidewall height: 8.0 in
- Section width: 255 mm
- Rim width range: 6.5-8.5 in
- Wheel diameter: 17 in
Note: The calculated overall diameter of 255/80R17 tires is 33.1 inches. Actual mounted diameter may vary slightly (±0.1 - 0.3 inches) depending on manufacturer, tread design, and load rating.
What Vehicles Use 255/80R17 Tires?
What Vehicles Use 255/80R17 Tires?
The 255/80R17 produces a ~33-inch diameter tire and is popular on off-road and overland builds where height is needed without added width. Common fitments include:
- Toyota Tacoma - most popular platform for this size; fits as a 33" tire on stock suspension with minimal clearance issues
- Toyota 4Runner (4th and 5th gen) - common upgrade for added height while retaining a narrow footprint
- Jeep Wrangler (JK/JL) - chosen for the narrow traditional look or improved snow tracking
- Lexus GX460/GX470 - used in overland builds thanks to generous wheel well clearance and Toyota truck underpinnings
- Ford Ranger (T6) - occasional fitment for owners seeking a taller stance; verify clearance by trim
255/80R17 Tire Size Load Index and Speed Rating
Most 255/80R17 tires carry a load index of 120-121 and a speed rating of Q (99 mph) or R (106 mph).
What that means:
- Load index 120 = 3,086 lbs per tire
- Load index 121 = 3,197 lbs per tire
- Typical construction: LT (Light Truck)
- Common load range: Load Range E (10-ply rated)
Because 255/80R17 is a true 33.1-inch tall, narrow off-road size, nearly all options are built for heavy-duty use. The Load Range E construction provides higher inflation capacity and stronger sidewalls for towing, overlanding, and puncture resistance.
The Q and R speed ratings are lower than passenger-car tires because the 255/80R17 size prioritizes durability and traction over high-speed handling.
255/80R17 Off-Roading Performance
The 255/80R17 is a 33.1-inch tall, narrow “33” tire designed for off-road traction, ground clearance, and reduced rubbing compared to wider 33-inch sizes. Why it performs well off-road:
1) Ground clearance with less rubbing
At 33.1 inches in diameter, it delivers the same axle clearance as 285/70R17 (~32.7-33.0") but with a narrower 255 mm section width. The reduced width lowers the risk of frame, control arm, and fender liner contact during steering lock or suspension compression.
2) Improved traction in mud and snow
The 255 mm width increases ground pressure compared to the wider 285 mm tires. Instead of floating on loose terrain, the tire cuts down to firmer layers, improving forward bite in mud, snow, and soft dirt.
3) Strong performance when airing down
With an 8.0-inch sidewall, the tire has significant vertical flex. Lowering pressure lengthens the contact patch substantially, improving rock grip and uneven terrain conformity while maintaining sidewall strength typical of LT Load Range E construction.
Because of its tall-but-narrow profile, 255/80R17 is often chosen for overland-style builds where clearance and articulation matter more than maximum tread width.
