Spare Tire Mounting for Trucks, Trailers, and RVs
A spare tire is only useful if it stays put and comes off easily when you need it. Spare tire mounting covers everything from bolting a reinforced bracket to a trailer frame to installing a swing-away carrier on an RV or under-bed mount on a semi.
Drivers usually call us for this after a factory mount rusts through, a new trailer or truck arrives without a carrier, or an aftermarket spare needs a mount strong enough to hold up on I-40, I-17, or the long stretches of US-89 between Flagstaff and the Grand Canyon. Fleet managers also schedule this work when retrofitting older trailers to carry a spare instead of routing every flat through a shop visit.
Whether you drive a tractor trailer, a straight truck, or a fifth wheel, a properly mounted spare turns a roadside tire service call into a quick swap instead of a wait for a tow.
How We Mount Your Spare Tire
Our Spare Tire Mounting Process
Every mount job starts with a phone call and ends with a spare that will not shift, rattle, or fall loose on rough highway. Here is how our technicians handle it from dispatch to drive-away.
-
Call and Rig Assessment
Tell our dispatcher your location, your vehicle type, and what kind of spare you're running. We confirm the right bracket, swing-away carrier, or bed mount before the technician ever leaves the shop.
-
On-Site Inspection
Once on scene, the technician checks the trailer frame, truck bed, or RV undercarriage to find the strongest, most accessible mounting point for your specific setup.
-
Mount Installation
We bolt or weld reinforced hardware rated for heavy-duty spares, then secure the tire itself. Every fastener is torqued to spec, whether it's a commercial truck tire service job or a lighter RV application.
-
Final Safety Check
Before we leave, we test the carrier or bracket under load, confirm the spare is theft-resistant and road-ready, and walk you through any maintenance the mount will need going forward.

Tire trouble does not wait for business hours, and neither do we. Our crews run 24/7 roadside assistance for stranded motorists, RV travelers, and fleets facing a truck breakdown service call at 2 a.m. or 2 p.m.

Signs Your Spare Tire Mount Needs Attention
A worn or improperly installed mount usually shows warning signs before it fails completely. Watch for these issues and call before a small problem turns into a roadside emergency.
- Spare tire rattles, bounces, or shifts while driving
- Rust or corrosion has weakened the mounting bracket
- A swing-away carrier won't latch shut or swing open freely
- The spare sits loose in an aftermarket bed or underbody mount
- Carrier bolts are stripped, bent, or missing entirely
- No mount exists at all after a trailer swap or tire upgrade
