Spare tire carrier is 5 star. The issue I have with the design is that it lowers the tow hitch by 2”. This drops the tow point for my toad to the minimum acceptable height and causes it to drag on the pavement often when leaving elevated parking lots. It would be great for Roadmaster to offer a design that would raise the tow point 2” to give purchasers the option to raise rather than lower the tow point. Tow bar manufacturer does not allow more than one connector between the tow bar and the motorhome, so device to raise the tow point is not an option.

I've used the Roadmaster Hitch Mounted Spare Tire Carrier for the last year (2023) and have put over 7500 miles on it. The carrier has performed seamlessly and is still manageable when mounted 40 plus inches off the ground. I have it attached to a Torklift 5' extension that goes into a 3" receiver welded into my flatbed. To prevent bouncing I've had Torklift put in a support bracket from the lower(regular) receiver. No bounce!

Hang em High. Instalation time about 30 minutes with the help of my son 1 hour 30 minutes. He doesn't need to read instructions. He so smart. Well any way there is a bolt that bolts to the receiver note bolt to. It wouldn't fit so son decided to hammer it in. Guess what round peg square hold. Then son discovered it screws in and he has screw it up. After re thread bolt works great. Lesson don't let 52 year old son install with out reading instructions. This weekend I will mount the tire.

Only problem with the carrier is that I installed it on my Ram Promaster 3500 Van. You will need a 12”extension to push the carrier out so the back door will open.

I know some will agree, not agree, or don’t care about this post. It’s about having a spare tire with you in case the worst happens and you need one. I just had new tires on our class C 2017 Sunseeker. I changed the spare also, since it was 7 years old as the ones on the rig. Never had an issue with them, Michelin tires, but felt age was the deciding factor. I went with General Tires, with the hope that some of the mushy feeling might diminish some. And it did!! The sidewall is a little stiffer than the Michelins, thus giving a stiffer ride also. Can’t have the best of both worlds yet in tires, but I’m happy with the stiffer ride. Now to the spare, mounted under and behind the rear axle. I always check tire pressures before a trip, even the spare. Never really noticed how it was mounted; just thought it would be let down like a lot of my pickups I have owned for years with a cable. Nope!! One stud bolt and nut, that is all. It was mounted solid, but to drop the tire down was another story. It took 3 men at the tire shop to lower that tire assembly, it weights 80 pounds. That 16” rim and tire was very awkward and heavy for those men. What would happen if I had a flat and needed the spare, looks like an accident waiting to happen for 1 person to do by themselves. I now have my spare still mounted under the frame, same spot, but with a cable assembly I bought from eTrailer. Much easier and safer for anyone to lower the spare tire anywhere. Had to do a little modifying to allow the spare tire to be mounted with enough clearance to access the turning stud on the winch. Welded 4 spacers blocks giving 1-1/4” clearance so the spare tire would be snugged against them and allow the space clearance needed for the turning shaft. I used ½” emt conduit, ½” pvc coupling and a 1-hole ¾” strap clamp to secure the emt conduit in place on the rear bumper. The ½” conduit is just large enough inside diameter to go over the turning stud on the winch, yet loose enough to allow movement like a universal joint since it is not in perfect alignment. The conduit is attached to the winch stud with a 5/32” cotter pin. I welded a 3/8” drive short extension to the inside of the conduit to be able to use a ratchet, speed handle or drill motor to raise and lower the spare tire.

Spare tire winch seems well built. I got a little creative with the install.

Just what I needed to mount the spare on my Class C with the Ford E450 chassis.

You guys are real problem solvers. I had my spare tire mounted on my lid closing the well which contains a great storage area for jacks and other tools and is lockable. However raising the lid with the spare on it became problematic for weight reasons and the spare would hit against the window and wouldn't open far enough to gain access. Wallah, the Curt Trailer Hitch Mounted Spare Tire carrier solved all those problems inexpensively and contributed to a overall better look for the spare. Thanks to everyone involved with the production and sales of this as it sure made my live easier.

This was exactly what we needed. It is very well-made and it sits nicely into the hitch with absolutely no wobble. The only reason I gave it four stars was because of the difficulty in aligning the bolts to attach the spare tire. They are free floating so they can be setup for a variety of tires. But this makes it very difficult to align the bolts and try to tighten at the same time. I solved this by making a paper template of the holes from my spare tire. Then I bought 3 jam nuts and 3 washers to secure the bolts into position before lifting the tire in place. Now that the bolts are secured in the right alignment it will be easy to remove and replace the tire in the future. It would be a very simple thing to add these instructions and supplies to the kit.

Well built, hard to lift 200LB tire and get the carriage bolts to align. The M12 retaining ring would not hold the bolts. Used a ATV jack to make slight lift and wiggle bolts into location. I'm 62 work smarter not harder.

Adam from E Trailer was great to work with. Directed me to the correct products. Placed my order and the items arrived within time they were supposed to. I highly recommend E Trailer. I have purchased other hardware as well as electrical wiring harnesses from them and everything has been as advertised.

Great build quality......works as advertized.

This has been an excellent accessory to my motorcycle trailer as it allows much more room to maneuver people, motorcycles and equipment around without constantly bumping into the spare. This is a quality built item that stays put once installed. Actually looks great and has enough adjustability to center itself so that it looks OEM once installed. I needed to order longer screws for my aluminum trailer frame but they were inexpensive and fit perfectly. I also ordered a locking hard-cover for the spare so it’s secure and looks great too.

Will not work with 235-80 R16 wheels and tires. Not high enough.

The tire mount arrived quickly and in perfect condition. It is very sturdy and constructed well, but like others have stated it wont fit a square rv bumper without some modification. I used a jigsaw with a fine tooth metal blade and cut the two holes out larger on the mount then drilled the holes on the plate with a 1/2” drill bit to align with the modified square holes on the mount. See the picture and it will make sense. It’s too bad they didn't just design it to fit a 4” square rv bumper in the first place, so thats why 4 stars. But with a little easy machine work and some silver spray paint to touch up it works. Its the only solution for getting the spare tire to sit up on top of the bumper and not behind it so you can use a rack and it’s expensive but solves my problem.

Pictures showing measurements are incorrect, inside measurements are 3-1/2” not 4” as stated. I had to modify bolt holes to fit a 4” square tube bumper. Mount is installed and looks like it will work for me.
