Can SUVs be modified to mount a spare tire on the rear?

Theoretically, it is possible to perform such modifications. Below is relevant information: SUV: SUV stands for Sport Utility Vehicle, which differs from ORV (Off-Road Vehicle) designed for rugged terrain. The full name is sport-utility-vehicle or suburban-utility-vehicle, meaning a suburban multi-purpose vehicle. It combines the spacious functionality of a station wagon with the off-road capabilities of a pickup truck. Spare Tire: A spare tire refers to a backup tire for a car, typically matching the specifications of the original tires. However, some vehicles use special-colored wheel spare tires, compact spare tires, foldable spare tires, or run-flat tires to remind owners to promptly inspect and replace faulty tires.

Last time I modified my off-road vehicle, I considered mounting a rear spare tire. This is completely feasible but requires attention to several key points. First, choose a high-quality spare tire carrier, such as an aluminum alloy bracket with cushioning pads, otherwise screws may loosen on bumpy roads which is dangerous. Secondly, reinforce the tailgate hinges, as standard SUV tailgates can't withstand long-term weight—I've seen cases where they deformed and started leaking within six months. Also consider increased wind resistance and fuel consumption; mounting a spare tire can add about 0.5L/100km in city driving. Finally, I recommend choosing a waterproof spare tire cover, as rainwater and mud infiltration during rainy seasons can corrode the wheel rim. It's advisable to have this done at a professional modification shop—they can properly adjust camera positions to avoid obstructing the rearview camera.

As a seasoned driver who frequently travels on National Highway 318, I have a rear-mounted spare tire installed on my vehicle. This modification is indeed practical for long-distance overland trips. Last year in Hoh Xil when I had a flat tire, I managed to change it in just three minutes standing at the rear of the car. However, it's important to note the regulations - in some areas, installing a rear-mounted spare tire may be considered an exterior modification. A friend of mine was fined 500 yuan in Shenzhen last year for this. For the modification, I recommend choosing a rotating spare tire carrier, which allows tire removal without dismantling the entire bracket. Also, keep the spare tire weight under 25kg, otherwise the tailgate will rattle over speed bumps. Remember to regularly check the bracket screws, as they're particularly prone to loosening on bumpy high-altitude roads.

From a mechanic's perspective, modifying an SUV to carry a rear-mounted spare tire should be done within reasonable limits. It's best not to modify unibody-structured urban SUVs like the CR-V, as their tailgates lack reinforcement ribs and are prone to deformation. Body-on-frame off-road vehicles are more suitable, with models like the Land Cruiser even having factory-pre-drilled mounting holes. Key points on electrical modifications: the rear camera requires extended wiring harnesses, and the parking sensors need recalibration. A full-size spare tire is recommended, but avoid exceeding the factory size by more than two sizes to prevent rubbing against the wheel arches. It's advised to check the tailgate hinge lubrication every 5,000 km, and remember to add drainage holes to the spare tire cover.
