Bumper Spare Tire Mount - U-Bolt Mount - TR-1

This universal-fit tire carrier from Stromberg Carlson boasts superior strength and is an excellent tool for all travelers.


Rec'd the spare tire mount today and mounted it on the rear bumper of our travel trailer in minutes. Looks great and seems that it will be stronger than the ones I saw on [online]. Most of them got bad reviews due to the metal bending or welds breaking. A lot of them had the square tubing welded at a 45 degree angle from the bumper plate. In my opinion, this puts the weight of the tire out away from the bumper mounting plate, thus more stress on the welds.

This one has the square tubing that is vertical and should put the majority of the spare tire weight closer to the bumper where it should be. I cut pieces of rubber tubing and put on the U bolts so they wouldn't wear on the bumper and rust it. Although, if the spare tire mounts shifts around to the point where the U bolts wear off the paint and rusts the bumper, I've got bigger probs than rust.

I also made a cable with a lock to secure the spare tire. I don't care if the tire gets stolen. I made it so I could just join the ends of the cable together with a lock. We pull our travel trailer 400 miles up to Lake Superior 4 or 5 times a year. The cable and lock is just to make sure should something happen to the mount, the tire stays with the trailer. It's interstate all of the up to Duluth for us and we go through Minneapolis. The last thing we need is the spare tire coming off and bouncing across 8 lanes of traffic at rush hour.

One minor thing: there is a little rust on one of the welds where it looks like the powder coat didn't take. No biggie. It just holds your spare tire, for Pete's sake. Other than that, I'm as happy as a clam.

If you are starting to experience rust, we do recommend covering any types of scratches or scrapes with a rust-oleum type of paint. This will prevent the carrier from experiencing any further corrosion. I have a link below for your reference.



Spare tire carrier still looks new and is solid as a very pleased with it. Thank you.


Above average, very rigid, will work well for my application.



Perfect, no problem


Super easy installation. Honestly I didn't think it would be as sturdy as it is. -but it definitely is. Holds my 225/75 R15 spare nice and solid. I added the heat-shrink tubing to the U bracket and the rubber thread caps.

Its been a year and it still looks the same as it did when I bought it. The tire hasnt moved with over 2000 miles of traveling.


Haven't installed it yet. Will update. The box was delivered damaged.

The box does look like it was beat up along the way. I will have our Customer Service team reach out to you.


We searched to find a spare tire carrier for our recently purchased 1962 Shasta Airflyte. This was perfect! It raised the tire high enough so we have no worries about bottoming out. We mounted spare tire on new rim with baby moon from E-Trailer. Looks great


It looks good and appears to be manufacture heavy duty. However it arrived a couple days later than thought to be, so I haven’t had a chance to install it on my equipment trailer. I’ll gladly update my review once it’s on the trailer with tire attached.


So simple to install. Great way to carry your spares on long travels.


Arrived very quick and look very nice.
be installing till spring because camper is in storage.
Now just need to get a tire and wheel for camper.


The original Casita spare tire carrier is poorly designed and placed. The Stromberg Carlson Spare Tire Carrier is exactly what I was looking, simple/easy install.



GR8! Still right where I put it. Check the nuts on a regular basis.


Listed for 14” rims also, but indicates otherwise. I checked the fitting and they work on my 14” rims.


Photo shows spare tire mounted with the bumper mounted u-bolt mount TR-1 tire carrier we purchased from etrailer. Easy install and holds tire firmly, eliminates hauling spare in pickup box.


Simple install, got my spare tire mounted, just need a little longer piece of steel to hold the wheel on the mount. Not a big issue, I had the extra steel in my shop. Much sturdier than I had anticipated so I’m very satisfied


I had to replace my original spare tire mount due to it developing a crack completely across one of the mounting lug holes. This replacement mount bolted right up to my 4 inch square rear bumper just like the original did. I had it done in about 20 minutes. I replaced it on a Rockwood 2503S Mini Lite which has 14 inch tires and 5 hole wheels. I can’t give an opinion on its durability because I haven’t taken it on the road yet. Only after bouncing down the road for a while will I know how durable it is, but it looks and feels sturdy.


Great product! Shopping with e trailer is amazing, very easy and hassle free!! Our go-to for all of our personal and business trailer needs!


Excellent quality , easy to install


Perfect replacement for a damaged original. Went on quick and easy with minimal effort. Well built.


solid construction and easy to install. I was able to offset it so I could use the receiver for a bike rack.


Great product, super easy install. Had it done in about 20 minutes. Says it’s for a 15 or 16 inch tire but, it holds my 205/75R14 just fine. I did take some vacuum tubing, split down the middle and put it on the u bolts where they rest against the bumper ( shown in photo with red arrow, just to avoid metal on metal). Great price point to solve a saltire storage problem.


Exceptional quality & powder painted fi nish.


fast shipping and good product. easy install instructions


Our fiberglass travel trailer came with a spare tire that bolted against the body of the trailer, leaving a permanent black donut on the gel coat. Never liked that setup. This spare tire carrier was a breeze to install, is extremely well-built and took care of my issue with the original spare tire holder.



It’s a strong unit. Still working as expected.


Solid/ fits/ works


I mistakenly ordered the TR-1 because one of the photos showed a different cross bracket (2 holes instead of one) which holds the tire in place. My 2018 Prime Time Crusader came new from General RV with the TR-1 holding the spare. It gradually failed with the center bracket becoming bent to the point that the tire was ready to fall off. I re-bent the bracket, put it back on but it happened again. Reversed the bracket but it bent the other way.I had to do this repeatedly. I will try to use the TR-1 if you send me an additional bracket for more strength. Thanks. I can send photos if you like.


Having had experience with trailer tire blow-outs, I decided to start carrying two spare tires (just in case). I already had one of these same spare tire carriers and needed to add the second. Works as advertised.

Still doing its job.


Easy to install. This carrier has traveled over 6000 miles on the back of my trailer with no issues. I am currently taking it another 4000 miles this summer.



As advertised. This product is a no-brainer.
