Side by Side Comparison of: Master Lock vs ADCO

Great product. Gives me a feeling of security regarding my spare at the boat ramp.

Fits the spare tire lug nut on my 2016 Keystone Hideout travel trailer perfectly - highly recommend this for your spare tire

Fit perfectly on my spare tire for my trailer!

Safety-Keeps honest people honest.

Well made and I feel that it provides the safety I need so that my spare trailer tire is not stolen.

The lock was easy to install. Keeps our spare tire safe.

Fits perfectly and stays put. I have had this on my spare tire for almost a year and have not had make any adjustments to it. It is strong and has not worn any. I would certainly buy again if this one ever wears out. Doesn't look like it is going wear out any time soon.

Nice cover. Added a decal to spruce it up a bit. Fits well and holding up well.

The purchase price was so good that I was afraid the quality would be lacking. However, I was very impressed with the overall quality of this cover. It fit perfectly and looks really nice. Time will tell how it will hold up but I really expect this to last a number of years.

Thanks to the reviewer that posted the size chart, I was able to order the one I needed (size N). It fits great. Following the directions and what other reviewers said, I covered the tire with plastic first since I bought the white one. The vinyl seems to be fairly hefty, but only time will tell how well it holds up in the sun. My tire it mounted horizontal, so it will be getting the sun full blast For the price, I figure if I get a year out of it, I will be happy

I measured the tire, 27". When I got the cover, the box showed that, based on the tire numbers, I should have gotten a 29" one, so I worried that this 27" would be too small. It's not. It fits snugly like a fitted sheet, which is important because otherwise the wind will blow it off. It covers the whole tread of the tire, with a little extra around the edge to hold it on. Align it so that the split part is on the bottom for rainwater and mud to run out. It's important to have a cover because otherwise, I know from experience, the spare will sun-damage on the top surface until all the tread is gone and wires are popping out, and a perfectly good spare is ruined.

Older model Honda CR-V - fits rear 205/15/75 spare tire [although snug]However snug fit in my view makes appearance more "stylish." Also like the sheen to coveras contrasted w/ 2 prior Bully covers bought on Amazon [for about same price.]The 3rd Bully I just bought [and returned] began to tear at two seams, after 3-4 days.So we like the look of the ADCO much better and hope it does not tear or rip for a long time.Be sure it fits your size tire and buy the correct model. See photos of #1737 on the CR-V.

Fit on spare tire mounting bolt but the lock itself doesn't feel that strong.

no bad for the money

good deal, does the job

ok

Looks good, but, won't work if you have recess lug nuts.

So that it works universally, you will need to purchase a lug nut that it will cover. The cap lugs that are standard on our boat trailer were not compatible. A quick trip to NAPA, Pep Boys, etc. and the spare on my boat trailer is locked. As is the case with any lock, a motivated thief will get past this, but as a deterrent, it is certainly satisfactory.

This was everything it was I expected. It covered the tire great and was easy to install.

It's a cover, but it doesn't seem to last much more than a season or two before cracking.

Well, I should have gotten the next size bigger. My tire is around 26.75", maybe a bit bigger but less than 27". I measured it and I calculated it using math. It was extremely hard to get it on. The seam doesn't go past the tread so it doesn't wrap around the tire very much at all. I am not sure if even an inch. There is no way to secure it like grommets or something. I am going to be stationary for a real long time, so it is fine. It keeps the sun off of the tire. If I go anywhere, I will definitely get a bigger one.

Covers the spare tire for my F450 beautifully.

They fit! I cannot for the life of me figure out why the company's website nor Amazon cannot figure out how to add the wonderful sizing chart that is on the box to the website or ad. It would make life easier for everyone. Here it is to help you get the right size.I have 4.80x12 tires on my kayak trailer that I need to protect. These slipped on easily, and allow me lock the wheel as well. They have a nice pliable feel, not too light, not to heavy. The directions say to wrap the wheel in something to avoid discoloring, but that is just not something I am too concerned about. I hope I get several seasons worth of use out of them.

Fits tight on my ST 205 75 14 trailer tire which measured 26" tall by 7 3/4" wide. Tight should be good in my case but if tire was slightly bigger may not have fit. I found Adcoprod.com for fit recommendations and I'm not sure #1757 would fit a 27" diameter as it states. Although the cover diameter is truly 27" the tread coverage section and elastic band seem small.

did not hold tight with the wheel you have enough space to push a pry bar between wheel and lock. will not recommend

Measure your lugs BEFORE purchasing. It wouldn't fit, but I used it on the license plate so not a waste.

Initially I looked for a different brand of this type of lock I have used for years but it no longer seems to be available as it fit my trailers well. Be aware on this Master Lock version that the hole in the outer cover that slides over the lug nut stud is 3/8" diameter. I had to drill it out to 1/2" to work on my trailers.

I needed to drill this out to fit the spare tire mount which wasn't too much of a big deal.I leave this in the toolkit unless we're going for a dayhike or trip around town when I'm RVing.A prybar should quickly defeat this but if you have multiple layers of protection for your belongings this just helps

I like this lock, however I had to drill the hole to make it fit the lug bolt. Drilling the hole marred the finish, making it less attractive. I do like the security of the lock, however the consumer should not have to modify the lock to make it fit.

I'm using this on the spare tire on my boat trailer. lock fits and locks. i just don't see why Master Lock is putting their name on this, the top flops around and can be brought past the back plate allowing a flat head or pry bar to be used to break it. this should stop a opportunist, but if some one wants my tire, they will most likely get it (even if this wasn't flimsy if someone wanted the tire bad enough I'm sure they would find a way)

Went on easily because I ordered one size larger then my measurement. Extreme white in color.Not as heavy duty as I expected as past Adco covers were heavier so maybe I ordered different weight but, did not see heavier duty in stock.Would order Colonial white if they have them.

This says it fits 29" tires. It is really too big for mine. I think I will now look for one using the tire type not size.

Looked great and seemed to fit well, but blew off on the highway the first time out. If you get this, add some rope or bungees to the back to keep it from flying off.

I purchased this cover for a 205/75R 14 trailer tire, which has a diameter of 25.5". The quality seems to be good but the ad is a bit misleading. Although the cover will fit a 25.5" diameter tire and will fit a 205 14" tire, it is actually designed for a 205 tire with a Aspect ratio no greater than 70 (143.5mm). On a 205/75R14 tire (Aspect ratio of 75 equals 153.25mm) the stretch cord will barely reach over the tread, onto the backside sidewall, because of the additional 10.25mm (0404") width. You can make it fit a 205/75R14 if you warm up the cover to 70F or greater and stretch the vinyl cover. It will fit, but will be very snug.

Bought two of these, one white, one black. OK quality but the stitching at the lower part is very crooked causing the cover to not fit well .

This tire cover fits my 14" trailer spare tire perfectly. It looks nice and appears well made. I'm pleased with the appearance and the quality.... and the price!Updated review: This cover has suffered badly from UV exposure and is cracked and peeling. I'll replace it with another brand.

Great idea/concept, but not for all applications, I suppose. Lock latch wouldn't engage backing plate. Had to return it, look for something else. FYI, the hardware this unit was mounting over was probably too large, the threaded shank being 1/2'". Anything smaller may have worked.

had to adapt it to get it to work on a longer stud

A good concept, but hard to attach and then to get back off, and it's very easily bent.

Cheap

I have a Suzuki Jimny. The spare tire is held on with 19mm round top nuts. This lock fits on with no problem but there is too much play - its loose and shakes around. By moving it you can create a large space to stick a flat head screwdriver in and pry it off. This is a deterrent, like a dummy security camera, but gives little protection.

Does what it's supposed to do but I really did expect something a bit heavier duty from Master Lock. I'm not sure it would take much of a hammer to break it off. If I did it over I would have bought one of those HD braided cable locks to protect the spare tire instead of this. Sorry Master Lock but it looks like you have fallen into the cheapo products category now too.Don't manufactures realize we would rather pay a bit more and get something GOOD?

Arizona sun roasted this sucker in a about a year. (I kept them in place for two, but the vinyl disintegrated and made a big mess.) They fit fine, and I supposed they suited their purpose (cheaper than new tires.) but I"m going to try something else instead of buying these again. Maybe AZ sun is too much for anything to last long.

Work for 2 months and the then faded and ripping. Got one at Academy for $15 and it comes with a drain slit.

fit as designed, seemed well built when I put it on but its only been 2 months and where it contacts the tire its all brown bleeding through to the front and looks dated now. Not sure why they don't line the inside with something heavier to prevent the bleed through...wish I knew and I would have bought a black one

Cheaply made. The seams are crooked, and it bunches up in some areas and is too stretched in others. Would not recommend or buy again. You get what you pay for here.

I bought this cover in October of 2013 to replace the original that came with my trailer I bought new in late 2008. The original cover eventually lost its elasticity and found its home on the highway somewhere. The replacement cover fit well but has only lasted a little under 2 years before beginning to disintegrate. My trailer is covered 7 months out of the year so sun exposure to the tire cover has been 10 months over its lifespan. Based on the price I suppose I should not have expected much however if you are looking to get a somewhat more permanent solution I would look elsewhere

I am disappointed in the quality of this spare tire cover. The way the item is sewn causes bunching of the material and a poor fit. The price hardly makes it worth returning but I want to warn others who may be considering a purchase.

The hole is too small for the lug to fit through, and the lock does not secure tightly; a pair of pliers or a screwdriver could beat the lock.

Great idea but in therory but Does not secure very well. Even if the lug nut post is short enough, the back plate of the device sticks out from behind front part which is the lock. You can very easily get a crew driver between two and pry off.

I imagine this lock will come off easily with a pry bar.

Not worth the money, the hole is too small to fit the stud through it, plus it can all be spun around and a thief could steal it anyway. On top of that the spare tire holder on mine is held on by nuts and bolts anyway. This would do nothing more than "keep an honest man honest."

It was difficult to install also I paid 9.25 for it and it is now listed for $6.57.

Save your money , this lock is junk. It does not provide a tight fit on the lug and is easily foiled with a screwdriver.

Drove about 200 miles and the cover is now ripped and flapping all over. Had to stop and remove it to prevent it from flying away.

Terrible fit, extremely loose. Vinyl bead that forms the diameter of the tire was choppy and creating flat lines rather than a smooth round continuous diameter around the tire.

Made in China, it ripped as I was trying to put it on the spare tire on my trailer. I verified that the correct size was ordered and received. The "heavy duty" fabric may fit that category when compared to 1 ply tissue paper. I was looking forward to replacing the factory cover because the old cover is stenciled to provide an advertisement for the brand of trailer. The old cover was easily twice as sturdy and is now back on the tire. Don't waste your money on this piece of garbage.

My Toyota Sienna has 235-55-18" wheels which are 28.2" in diameter. I got size F which is for 29". It was very easy to put on, but seemed to fit OK. It wasn't real tight. It worked fine on the roads in my area up to 65 mph. But the first time I got on an Interstate and accelerated to 75 mph, it immediately started flapping around and blew off. By then, it was past 30 days and too late to return to Amazon. The material feels OK after one month, but we park in a garage so that isn't a very good test of durability. If I had it to do over, I would have gotten a size "I" as in India which fits 28" tires. Per other reviews, I put a black trash bag between the tire and cover to prevent the white cover from turning yellow.

Show the dang tire size chart on your add! Lordy how many wrong size complaints do you need before you give a size chart?

Came off on the first trip (40 miles) never to be seen again, waste of money. Yes it was the correct size, just not strong enough elastic to hold it on I suspect.
