Video Transcript for Fulton Spare Tire Lock Review

Today we're going to be taking a look at the Fulton Spare Tire Lock. This is part number FSTL0603. This is a metal construction spare tire lock designed to go right over your current lug nuts and secure it in place. We've got our boat trailer spare here. We'll be putting it on in just a second so you can see how it works. It comes with two keys. It's got a removable base.

This is going to accommodate all the way up to a 9/16 of an inch wheel stud and for the longer wheel studs, the cap's removable so that stud's going to be able to come right through. We won't have any worries about getting to a point to where we can't get our lock onto our tire. There's a locking tab here on the rear. When installed that's going to prevent this lock from moving or turning. It works great with both the wheel studs and with the U-bolt style spare carriers so you won't have a big issue with getting this to work on most of your spare tire setups. As far as installing it goes, we're just going to remove one of our lugs. With that off, we'll separate our rear plate.

That goes right over the stud and our lug nut goes right back on. It's got a cone pattern in there which is great. It allows that lug nut to seat right in there where we want it and we just tighten it back down. Now we'll take our lock and cover, place it on, turn the key and just like that our spare tire is secured to our trailer. We're not going to have to worry about it missing. Now that we've gone over all the features and we've seen how it works, that will complete today's look at the Fulton Spare Tire Lock, part number FSTL0603.

Been on my trailer for a year. Still looks new and has not loosened up at all. Still doing its job.


Comments
Still going strong. Ive never had to tighten it after the initial installation and the trailer has been on several trips and some very rough trips.
Ryan - 11/16/2022


by:

I ordered two mounted tires and wheels and two Fulton spare tire carriers. The tires were shipped in two different boxes. The spare tire carriers were put one each in the box containing the tire/wheels. When I opened the boxes, both of the spare tire carrier packages had come open in transit and the contents were scattered inside the tire boxes. One was fine and all parts were there and in the second, the keys for the spare tire carrier lock were missing. I called etrailer and told the representative, Ericka, what occurred. They were super helpful, professional and friendly. etrailer is sending me a replacement. Fantastic customer service! I highly recommend this company!




by:

It arrived a few days after I ordered. Installed quick. It’s to deter a quick theft. If a person really wanted to take the tire it’s not going to stop a large hammer.




by:

I have an odd single 1/2" 13 pitch stud for my trailer's spare tire mount. I used a nylock nut nut to mount the spare. I purchased this lock to keep it secure. It appears to be working fine. I don't know that it is as secure as a traditional locking lug nut someone would have to work at it to get it off without the key.




by:

Very useful locking device.the only flaw?the removable rubber plug should be higher that way it will protect the locking nut plus it will detract attention from someone else actually seeing how the lick works and maybe try to pry it open




by:

At first when I received the item it look pretty well made. But when I was installing it I noticed a crack on one of the hardware. So I called etrailer back and spoke with Teresa on customer service. She just ask few questions and she immediately send me a brand new one. That’s 5 star on customer service. And she even told me not to return the defective item. So etrailer Big thumbs up on that. Now hope this product does its job from thieves.




by:

Did the job as advertised. No problems at all.




by:

I think this will do the job. With the lugnut tightened down, you cannot turn this device with your hands, and even if you could turn it, I don't think you could get the lugnut off. Also, I like how the cover is a bit loose and yet covers the nut completely. My bolt did protrude slightly, so it is good that the rubber cover is removable for the longer bolts.




by:

Happy with the looks and function of the spare tire lock on my Maxey utility trailer. Design is innovative and I had no problems installing it.




by:

I received the device with the plastic packaging open and no lock!!




by:

pleased with the unit, easy to install. Be sure to store the keys safely and where you'll remember they are located. Don't ask me how I know.




by:

Great product, good price, perfect size, easy to install, installed it on my boat trailer spare now I don't have to worry about the tire being removed without a struggle.




by:

These locks are low profile, easy to install and seem quite sturdy. I am very happy with the product and service.




by:

Worked as intended. Shipped here on tim e,




by:

always the best place to go for trailer items. Quick shipment, good prices...




by:

Installed easy but haven't had to use it yet




by:

Works as promised but my particular wheel has deep narrow sockets and did not allow attachment from the outside. Attaching from the inside solved the problem with equal security. Simple and effective. Love it.




by:

Called my order in to etrailer and it was shipped out as promised. Really pleased with their prompt service. Thanks




by:

Does what it is suppose to do.




by:

Nice lock set up!




by:

Simple to use,. One out of three was difficult to open.




by:

Great product to secure your spare tire from wondering eyes




by:

My trailer isn’t going anywhere…unwante d.




by:

First of all the packaging this item arrived in was open on one end but the item looked fine, no scratches, dings or signs of wear. I carried it outside to my driveway and removed 1 of the 2 lug nuts from my trailer spare tire mount, I placed the smaller back half of the spare tire lock over the lug and hand tightened the lug nut until it made contact and seated against the spare tire. I then placed my 4-way lug wrench over the lug nut and gave it a free spin. The free spin was only about 1 and 1/2 spins since I had already hand tightened the lug nut. I began to turn the lug wrench by hand, 1/2 turn, feeling no resistance so I turned another 1/2 turn, still no resistance. On the 3rd 1/2 turn and still feeling little to no resistance, the back half of the spare tire lock spread and cracked which would not allow the locking cap to fit over it. after further inspection of the crack, I could see this was made of a soft pot metal (see uploaded image) and not of a stronger metal such as steel. This item broke under minimum tension, no way near the type of tension/torque one would use to install a lug nut on a mounted tire you would be driving on. I feel my money was wasted on this particular product. I have always been satisfied if not overjoyed with all of my past purchases from etrailer.com and am not blaming etrailer.com for this products shortcomings.

  • How Does The Fulton Spare Tire Lock Part # FSTL0603 Work
    The Fulton Spare Tire Lock, part # FSTL0603, has a tab that is placed behind the lug nut of your spare tire and then the lock is placed over the lug nut. The enclosed and locked lug nut prevents the wheel from being stolen or removed without a key. Part # FSTL0603 works great for open-ended lug nuts and will only work with closed end lug nuts that are less than 1 inch tall. I took some pictures of part # FSTL0603 on a wheel to demonstrate how it works.

  • Does the Wheel Need to Be Removed While Not in Use on the Dutton-Lainson Spare Tire Carrier
    I checked with my contact at Dutton-Lainson and unfortunatly neither they nor we have a photo of the Trailer Spare Tire Carrier and Dolly Bracket by Dutton-Lainson part # DL22144 installed and in use on a trailer at this time. With that being said the carrier/tire does not need to be removed while not in use. The tire can simply be left on the carrier until the time in which it is needed arises. The above carrier/dolly works with most 8"-12" wheels that have either a 4 or 5 bolt pattern....

  • Recommended Spare Tire Lock for Trailer
    The Spare Tire Lock # FSTL0603 only fits lugs up to 9/16 inch. The 3/4 inch you referenced will be too large. To lock the spare you will leave one of the bolt off and then use the etrailer Spare Tire Lock for 1/4" to 7/8" Thick Rims - Keyed Alike # e98892 thru the carrier and the wheel. The lock stud diameter will be 1/2 inch and yet the ability to tighten and lock will not be an issue with the other bolts in place.

  • Will The Trailer Spare Tire Carrier DL22128 Move Around While Driving
    When you tighten the two nuts on the studs of the Trailer Spare Tire Carrier # DL22128 you were looking at, it will squeeze the tire against the frame which will keep it secure and won't allow it to slide back and forth. I wouldn't hesitate to use this product on my trailer, and with a 4.8/5 stars from our customers I can confidently say it will be a very reliable option to transport your spare tire. Regarding areas for mounting the U-bolt, the most common location is on the left front...

You may consider adding a lock like the Spare Tire Lock # FSTL0603 to discourage tampering with the spare tire. This lock fits 9/16" wheel studs so you'll need to verify that on your end. Attached...

  • What is Fulton Lock # FSTL0603 Made Of and How To Prevent Theft of Fulton Tire Carrier # FSTC1000301
    Yes , the Fulton Spare Tire Lock, part # FSTL0603, is made of a hardened steel, which is very hard to cut or break. You can install the Fulton Hi-Mount Spare Tire Carrier, part # FSTC1000301, using a Loctite Threadlocker, part # LT37423. This is a liquid that will lock the nuts to the bolts and prevent anybody from removing them. To disassemble the nuts and bolts will require the use of heat.

    The Stake Pocket Tie-Down Anchor # T355 measure 3-1/2" by 1-1/2". If you measure again (sand down if necessary), you probably actually have the standard 3-1/2" by 1-1/2" opening and not 3-1/2" by 1-3/8", in which case this would work well for you. For a spare tire carrier that would fit the standard 3-1/2" by 1-1/2" stake pockets we have the Buyers Products Stake Pocket Spare Tire Carrier # 3375201012 or the Brophy Trailer Stake Pocket Spare Tire Carrier - Black Powder Coat # SPTC.

Since the bolt is smaller than 9/16 inches, the Tow Ready Spare Tire Lock # FSTL0603 will work well with the spare tire carrier. This spare tire lock will keep the wheel secured to the spare tire carrier. I've attached a review video of this lock for you. The Wheel Lock Set # RG01-150...
