Jay J.Does the Ford Bronco Have a Full-Size Spare?
Yes. The sixth-generation full-size Bronco carries an externally mounted full-size spare on the rear swing gate. From the factory it is intended to match the size of the four road tires; it is not a temporary donut. A stock Sasquatch Bronco carries a nominal 35-inch spare and a Bronco Raptor carries a nominal 37-inch spare.
What Spare Tire Size Comes on Each Bronco Trim?
Check your year and package, not the badge alone. For 2026, Ford lists nominal 30-inch tires on Base, 32-inch on Big Bend and Outer Banks, 33-inch on Badlands, 35-inch on Heritage and Stroppe, and 37-inch on Raptor, with optional Sasquatch configurations using 35-inch tires. The original spare should match the intended tire diameter of that package. Check the driver's door sticker for the factory tire-size code on your individual Bronco.
Where Is the Bronco Spare Mounted?
It mounts to the rear swing gate, with the rearview camera integrated in the spare-carrier area. This makes the spare easy to access but also means a different wheel offset or oversized tire may obstruct the camera, rear glass, bumper, third brake light or tailgate opening. Check those clearances before ordering a replacement wheel.
Does a Matching Spare Need the Same Brand?
Ideally carry the same tire model and size as the road tires, particularly for longer off-road trips. Two brands with the same nominal size can have different measured rolling diameters. If you change to 35s, buying only four new tires leaves the original, smaller spare as a poor match. A matching fifth tire is an important part of a larger-tire budget.
Can the Stock Carrier Hold a 35?
Not every carrier is the same. Factory Sasquatch Broncos were built to carry their 35-inch spare, but a non-Sasquatch vehicle with a different wheel and tire combination may need repositioning, a different mount or reinforcement. Verify complete wheel-and-tire weight, actual diameter, section width and wheel offset. There is no single reliable universal tailgate weight limit across every Bronco year and configuration. Check the vehicle and carrier documentation rather than treating forum estimates as a specification.
What About a 37-Inch Spare?
The Raptor carries a factory 37-inch spare, but that does not make the Raptor carrier interchangeable with every standard Bronco. For a standard Bronco upgraded to 37s, consider tire-to-bumper clearance, camera position, door hinge loading and any required reinforced carrier. Also assess whether the gate can open fully without hitting the larger tire or other accessories.
How Do You Choose a Spare Wheel?
Match bolt pattern, center bore, wheel diameter and width, offset, load rating, and tire diameter. A wheel that bolts to the hub may still sit too far toward the carrier or put the tire against the rear bumper. Before spending money, measure the mounted wheel-and-tire assembly, including how far the sidewall extends from the carrier. Check the third brake light and camera with the tailgate shut, then swing the gate fully open and confirm bumper and body clearance.
Can You Drive in 4WD With a Smaller Spare?
A substantially different rolling diameter can force the wheels to rotate at unequal speeds and place unwanted load on four-wheel-drive components. My recommendation is to carry a properly matched spare for any remote trail trip, and never assume a smaller spare is suitable for prolonged 4WD operation. If you must use a mismatched tire in an emergency, consult your model-year manual for permitted temporary use and arrange a proper replacement promptly.
What Should You Check Before a Trail?
Check the spare's air pressure, sidewall age and cracking, lug wrench and jack access, locking-lug key if fitted, and camera visibility. Practice finding the supplied jack and lifting points before traveling remotely. On a rocky trail, use a suitable stable work area rather than attempting to jack a vehicle on a steep slope. A spare exposed on the rear gate still ages even when its tread has never touched the ground. If the camera image changes after carrier work, inspect camera position and bracket interference.
