If you’re like me you like a nicely dressed tire to go along with your perfectly detailed car. I’ve been using water based dressings for years now and although I like the look nothing seems to last very long.

I bought McKee’s 37 Tire Coating a couple months ago and have been waiting for the opportunity to try it. A few weeks ago I learned that a “New Formula” was available and Nick at McKee’s was sending out bottles free of charge to replace the original formula since it had been a disappointment to so many others.

This is the first time I’ve tried a tire coating so I’m hoping it will replace the numerous water based dressings I currently use.

Tires: 3 year old Goodyear Eagle LS2 with 24,500 miles

For the past 2 years these tires have always been cleaned and dressed – at least twice a month.

Product on Tire Before Cleaning: Gyeon Q2M Tire was applied about 1 week prior

McKee’s Directions for applying the Tire Coating

**TIRES MUST BE CLEANED WITH McKee's 37 Tire Cleaner & Rejuvenator**
1 Ensure surface is cool to the touch.
2 Thoroughly clean tires using McKee's 37 Tire Cleaner & Rejuvenator until all browning and previously applied dressings are removed. The tires are cleaned properly when a white foam is produced as you scrub them. IF YOU NEGLECT TO PERFORM THIS STEP THEN THE COATING WILL NOT PROPERLY ADHERE.
3 Allow the tire to dry completely before applying McKee's 37 Tire Coating.
4 For best results, apply McKee's 37 Tire Coating with a soft-bristle brush, like the Carrand Brush & Shine Tire Dressing Applicator.
5 Apply the coating directly onto the bristles and spread over face of tire, evenly distributing the coating.
6 Pay special attention to raised letters, ribs, and grooves.
7 If a glossier finish is desired, wait 30 minutes and apply a 2nd coat.


My Cleaning Process

Shine Supply Wise Guy was sprayed on the dry tires and left to dwell for a couple minutes and then sprayed off with the pressure washer.

As you can see in the next picture the tires were pretty dirty.

For the next several rounds of cleaning McKee’s 37 Tire & Rubber Rejuvenator was used with the Tuff Shine Brush and then pressure washed.

I didn’t count how many cleaning rounds I completed but the next picture shows some progress.

The most important thing I’ve heard about tire coating prep is to make sure the rubber is as clean as possible. When the cleaner is “white” on the tire it should be clean. Just when I thought I had cleaned enough I did another round.

Last Round of Tire Cleaning

After cleaning the tires they were blown dry with my Metro SideKick blower and left alone until the next morning. The tires had about 14 hours of dry time in my garage which was around 65 degrees.

Dry Tires – Ready to apply the Coating

Since I had never applied a tire coating before I wasn’t sure what to expect. Would it apply like water based dressings? The only reference I had was Nick’s YouTube Video and pictures with descriptions on the Autogeek Store product page.

I applied the coating directly to the brush and then spread onto the tire.

The next pictures are a series of shots taken at different points of the process. I completed 3 coats with a minimum of 30 minutes between them. I hope the pictures are helpful to others so you can see how much different the coating applies compared to water based dressings.

First Coat

The coating has a blue tint to it and is very watery. I found it difficult to apply an even layer but the coating self levels and turns clear as it dries.

First Coat after 30 minutes

firstcoat30min.jpg


You can see some excess product in different areas of the tire. I was tempted to take a rag and wipe it off but after watching some of the application videos it said not to wipe with a rag.

First Coat at 60 minutes – the product leveled out pretty good. In person the finish is fairly “Matte” and I like a little more sheen or “satin” finish so I decided to apply additional coats.

Second Coat – 1 minute after application

Second Coat after 30 minutes

secondcoat30min.jpg


As you can see I didn’t have as much excess product left behind. It didn’t take as much product this time either.

I liked the look after 2 coats but decided to go for a third!

Third Coat – 1 minute after application

Third Coat – 30 minutes after application

thirdcoat30min2.jpg


You can see some excess product remained but I left it alone.

Third Coat – 60 minutes after application

After 3 coats I achieved the look I wanted. The tire is dry to the touch and I shouldn’t be worried about any sling.

Overall I am impressed with the ease of application and the finished look. The only thing I don’t like is the bottle. When trying to pour it onto the brush it was like a 90 year old man trying to pee. It dribbles out and with the watery consistency it ends up running down the side of the bottle. They could improve the cap for dispensing the product – maybe a longer microtip spout.

Time will tell how well the coating stands up. I plan to update this thread over the next several weeks/months
 
Amazing step by step review lane5515! Loved reading your entire write-up.

I need to try this tire coating. I would love the shine of the tire to stay like that for months and not days. All without any sling! I'm very curious how long the shine lasts. Looking forward to your updates.
 
Very nice review. Thanks for sharing. It definitely will last longer than a water based dressing and it cleans up with just soap and water.
 
Great review and photos. The new formula looks nice with 3 coats. I ordered the new formula as well. Big fan of the previous version as I have been using the DP version. Looking forward to comparing the difference in both considering the new formula is supposed to be glossier.

Quick tip for next time to save you some time and be even more efficient.

Try using the sidekick in between coats. It will not only dry and cure the coating faster but it will push the coating into the nook and crannies. Big time saver and it is the way I have been applying multiple coats.

You would have been fine applying the coating to the tire as soon as you dried it with the side kick. Done it many times.

I recently switched over to the tuf shine tire applicators over the carrand brush. With the carrand brush I pinch the bristles with my index finger and thumb to have the coating sit right on top of the bristles. I feel that the bristles are more evenly coated this way.

I do agree with you about the flip top. That is one of the reasons I like the tuf shine foam applicator.

Enjoy the longevity of it. I get a little over 4 months before it needs to be reapplied.

Nice review update us in a month thanks again.I see that a great product for weekend detailer or hobbyists. BUT in the real world it's to time consuming and customers are not gonna pay for that time or premium service to coat tires.Some will but a large majority wont.
 
Looks great after 2 coats! Does longevity increase with coats or just gloss?

Good question - I'd assume longevity would increase some also but I'm not sure.

Thanks for the tip for the SideKick and using it to even out the product.

Great review- thanks! Looking forward to longevity posts.

Thanks!

Guz,

When you reapply after 4 months, are you starting the deep cleaning cycle over as in the first time application, or you apply or simply wiping on a new coat?

It depends. If it looks like it is starting to flake off I will redo the entire thing. If it is not I will just wash them real good and apply a fresh coat.
 
I have been using the first version on my dads car. Started with very clean tires and it lasts easily several months. Additional coats only amplify the shine, I dont think they impact the longetivity. The new version is supposably a little glossier. The first version is definitely more of a satin finish, and as it wears the tires maintain that new rubber look.

I did apply it to another car where the tires were not completely clean, and it did start to "peel" off. However, all I have been doing on my dads car is reapplying it once every few months WITHOUT cleaning (other than wiping them with the wheel woolie when I clean the wheels) the tires and have had no peel issues.

BTW, great review!

Hey, stop looking in my bathroom window!

Looking forward to updates. I also like your garage floor...any details on that? How old is it?
 
Nice write up and review. Pics were nice! I am glad you posted this...interested in doing this to my daily ride! Gonna do it soon! Thanks for posting.
 
I regret to inform everyone that I will not be able to post any updates on this product. I traded in my Sierra for a new vehicle yesterday so it looks like I'll need to start all over with the testing!
 
After trying a couple of other products, I gave this one a try recently. I prefer more of a deep matte black for tires. Reviews I read seem to suggest this might be the winner for me. Anything but. After several rounds of cleaning with their product - getting to "white foam" as the indication of clean tire. I used a small tire brush from Meguiar's for cleaning and a second one for application. I was surprised at how thin it was, but easy enough to apply. That said, I didn't like the look at all - like a coat of translucent wax to me. Second coat applied later didn't make things any better. Will be removing this and going back to a product that is working pretty well for me.

Hope it world for others, but this one isn't making the cut for me.

What are you using now? I would like to replace the Perl because it just doesn't last long.

Optimum Opti-Bond Tire Gel is what is working for me. Can't speak to the durability, but it gives me the look I want, which is reasonably flat dark black, like good tire rubber should be. No shiny, shiny for me.
 
Cleaned and coated my wife's summer wheels for her Forester XT. Cleaned with McKee's Tire and Rubber Rejuvenate which worked really well. Coated 3 times with McKee's Tire Coating. Should get them installed Wednesday night and can then monitor longevity.

Appearance is pretty good, definitely not shiny or excessively glossy. Very slick feeling. I'll post a pic once there on the car.

Could not see a way to edit this, but I wanted to provide some follow up. I had purchased this on a different site and written a review of my experience there. Since it was less than a five star experience, McKees commented on my review, including a way to get in touch with them. I did that and had a great conversation with them. The short version is that I invested in this product, based on past reviews, which were based on their previous formula. I got the newly updated formula, which had features most customers wanted, that is more shine - the exact opposite of what I was looking for. At the end of the day, it was just a mismatch for me. I can tell you that this seems quite durable - and this was a big part of my interest. For me, it was a miss on the visual front, but I'm one of the rare people that wants deep dark matte or satin rubber on my tires - helps the chrome shine the more, as my avatar reflects.
