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.

This was exactly what I needed for the spare tire on our Casita trailer. The removable plug lets you use it on any length bolt. 579122

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. 552975

At first I was a bit dismayed that the tire/wheel combo I ordered was unavailable. But I was offered a suitable substitute and the entire order was rapidly dispatched and received in a timely manner. I was very pleased with my order and the various items... so much so I immediately decided to order another wheel/tire combo for one of my trailers and use the two nice new wheels/tires intsead and use one of the old originals as the spare! Great products, fast service, super helpful customer service and they know their products! Thanks etrailer! I'll be doing business with you again real soon! 543763

I think the tire lock will deter the common thief, but not the person that is determine to take the spare tire. The lock appears to be strong and durable. I would recommend this item to a friend 59895

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. 466106

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. 818107

Was easy to install. It will definitely make it more difficult to remove the spare tire from the rear of my travel trailer 817585

by:

Due to the virus and not using the trailer much, the lock is still there and works OK. I really can't give a good review but so far so good. All the products I have bought from you have been fine, with the exception of the previuos wheel lock that was not a good design but you guys replaced for free! 814445

by:

Shipping was perfect! The brack was as described and worked as planned. It came with two bolts and a lock, which slid over the bolt to prevent someone from just unbolting and taking the tire. I bought a second lock for the other side. Call me paranoid. It isn’t much of a deterrent but the more I can aggravate the bad guy the better. Thanks etrailer for providing these needed products at a fair price. 812347

  • 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.

  • 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.

  • What is Spare Tire Lock Made of and Grease Cap for Trailer Hub
    To answer your first question, the Spare Tire Lock # FSTL0603 is made of metal and not plastic. In regards to the grease cap you asked about, since you got a 1.986" diameter you will want to use the Replacement EZ Lube Drive-In Grease Cap - 1.986" OD # 21-41-1 with the Grease Cap Plug # RG04-010. I have added links to video reviews for you to check out as well.

  • Spare Tire and Lock Recommendations Between Fulton and Dutton-Lainson
    Lock # 262DAT will fit both spare tire carriers # FSTC1000301 and # DL22120. It is designed to fit 1/2 inch wheel studs. The other lock you mentioned, # FSTL0603, is for 1/2 inch wheel studs. For a spare tire carrier I prefer the Dutton-Lainson carrier # DL22120 because it can fit taller frames (up to 3x5 inch) should you ever need it to and Dutton-Lainson does make a quality product.

  • Compatibility of Tow Ready Spare Tire Lock with Fulton Hi-Mount Spare Tire Carrier
    The Fulton Hi-Mount Spare Tire Carrier # FSTC1000301 is a great choice for a spare tire carrier. The bolt that holds the wheel onto the spare tire carrier is a 1/2 inch - 13 bolt that is 1-1/2 inches long. 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...
