Why Switch From Flotation (33x12.50R17) to Metric?

Real benefits for truck, Jeep, and overland builds.

1. Save $150 to $300 Per Set

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.

2. Factory Rim Width Compliance

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.

3. Reduced Weight & Less Scrub Rub

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.

Editor's Note on 33x12.50R17:The standard 33x12.50R17 is often too wide for factory 7.5" or 8" wide wheels, causing tire shops to refuse mounting. Metric equivalents like 285/70R17 fit factory rims within TRA approved specs perfectly.

Frequently Asked Questions: 33x12.50R17 Metric Equivalents

What is the metric equivalent of a 33x12.50R17 tire?β–Ό

The closest metric equivalent of a 33x12.50R17 tire is 285/70R17, which measures 32.7 inches in diameter and 11.22 inches in width. Other popular metric alternatives include 305/65R17 (32.6"x12.01"), 295/70R17 (33.3"x11.61"), 255/80R17 (33.1"x10.04") depending on whether you want a wider or narrower profile.

What does 33x12.50R17 measure in millimeters?β–Ό

A 33x12.50R17 tire measures exactly 838.2 mm in overall diameter, 317.5 mm in section width, and 203.2 mm in sidewall height, mounted on a 17-inch wheel.

Why should I buy a metric tire instead of flotation inches?β–Ό

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 33x12.50R17 rub on a stock truck?β–Ό

Fitment depends on vehicle ride height. Stock on Rubicon / Badlands; 1.5" to 2" leveling kit on standard half-ton pickups. 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 285/70R17 are preferred.
