Why Switch From Flotation (31x10.50R15) to Metric?
Real benefits for truck, Jeep, and overland builds.
Metric tires are manufactured by the millions as factory original equipment for trucks like the Raptor, Tremor, and Rubicon. Flotation sizes are specialty aftermarket tires with lower production runs and higher retail prices.
Most stock truck wheels are 7.5" to 8.5" wide. Tire manufacturers specify that 12.50" wide flotation tires require at least an 8.5" or 9.0" rim. Commercial shops (Costco, Discount Tire) will mount metric sizes like 285/70 or 295/70 without refusal.
A 12.50" wide tire creates a wider scrub radius that rubs against the front sway bar, crash bars, and frame. Choosing a metric equivalent gives you the exact same height with a narrower tread that clears without cutting.

Frequently Asked Questions: 31x10.50R15 Metric Equivalents
What is the metric equivalent of a 31x10.50R15 tire?▼
The closest metric equivalent of a 31x10.50R15 tire is 265/75R15, which measures 30.6 inches in diameter and 10.43 inches in width. Other popular metric alternatives include 265/70R15 (29.6"x10.43"), 235/75R15 (28.9"x9.25"), 245/75R16 (30.5"x9.65") depending on whether you want a wider or narrower profile.
What does 31x10.50R15 measure in millimeters?▼
A 31x10.50R15 tire measures exactly 787.4 mm in overall diameter, 266.7 mm in section width, and 203.2 mm in sidewall height, mounted on a 15-inch wheel.
Why should I buy a metric tire instead of flotation inches?▼
Metric tire sizes (such as 285/70R17, 295/70R18, or 315/70R17) are manufactured in significantly higher volumes for factory vehicles like the Ford Raptor and Bronco Sasquatch. This makes them $30 to $60 cheaper per tire. Metric sizes also offer a wider selection of heavy-duty Load Range E (10-ply) ratings for towing, weigh less (saving gas and making your truck feel peppier), and safely fit factory wheels without tire shop mounting issues.
Will a 31x10.50R15 rub on a stock truck?▼
Fitment depends on vehicle ride height. Fits factory stock on many classic 4x4s; 1" to 2" leveling or budget boost kit on others. On modern half-ton trucks (F-150, Silverado, Tacoma), full 12.50-inch wide tires often rub the sway bar or crash bars at full steering lock, which is why narrower metric sizes like 265/70R15 are preferred.
