Berryman Products 1301 Tire Seal-R Sealing Compound,1-Gallon Bottle

Wow. What an amazing product. I have a piece of land that is covered in these miserable seeds people call goat heads. One pass with my yard tractor and I picked up several. A couple days later I had 2 flat tires and one slow leak in the third. I bought this after seeing many reviews saying to stay away from "the green stuff".Day 1 - I followed the directions (see tips below) and after inflating the first tire I still heard the leak for about 10-15 seconds then it went silent. Cool, I though, but we'll see if they hold.Day 2, 3 - Still holding.Day 4 - Back to the field to mow and haul rocks with my wagon. A couple passes and I spot a nasty goat head embeded deep in my back tire. Nervously I pulled it out ... hiss for about 4 seconds then silence. COOL!Day 5 - The next day I went over the tractor tires and pulled out all the goat head thorns. It would have been half a dozen leaks, but the tire sealer sealed them.Day 7 - I'm walking by my wagon, grr 2 flats. The goat heads got my brand new wagon tires. I broke out the Berryman's and pumped some in. Again it worked perfectly. I though, hey my dolly always gets flats, so I pumped some Berryman's in those tires as well.Day 14 - All 10 tires are still fully inflatedTips:1. When you receive the product in the mail, before doing anything, put it in a garbage bag and go outside to unscrew the pump / open the jug. Because of the design of the pump, there will be some of the juice that will spray out and it makes a mess. No problem cleaning up, but it's still messy.2. When you pump the juice in your tire, make sure the valve stem is at 5 or 7 oclock. You will rotate the tire later, but when you fill you want it to fill near the bottom of the tire.3. If you have a tube tire, gently hold the valve stem with pliers while you attach the fill hose. Oh yeah, Berryman's works great on tubes as well.4. MOST IMPORTANT. Put a paper towel around the valve stem when you are taking off the fill hose. There will be a little displaced air in there now, so some juice will squirt out, so having a paper towel rapped around the stem keeps things nice and clean.5. After putting the juice in your tires, SLOWLY rotate the tires. This keeps the juice on the outside of the tire instead of getting it all over the rims.Quantities I used in my tires:Lawn tractor / larger riding lawn mowers Front tires - 8 pumps Back tires - 12 pumps Wagon tires - 6 pumps Dolley tires - 6 pumps

Where has this stuff been all my life??!! I’ve been doing things wrong (by changing inner tubes and replacing tires). This stuff saved me from replacing all 4 wheels (tires, inner tubes, rims) on my hose reel that has pneumatic tires. Assembly is a bit awkward - you are supposed to put the little clear plastic piece onto the white pump end, then attach the included hose to the plastic piece, and put the hose over the valve stem (minus its core valve). Just have some paper towels available to wipe up any of the mess that you might leave behind as this stuff makes a bit of a mess in-between removing the hose end off of the valve stem and getting the remaining product still left in the hose back into the bottle. So don’t say I didn’t warn you.I started putting this into other things that have pneumatic wheels (go cart, bikes, balls with bladders) that were constantly going flat over time and didn’t want to continue swapping out failing rubber pieces. This stuff either sealed it up completely by rotating the object per instructions to circulate the product, or was on its way to stopping the leak. Don’t forget to wipe the bottle pump for next time so things don’t accidentally get clogged up.

Stuff worse great but the pump is for using in like a hand soap, there isn't any way to attach a hose to use it to fill the tire. Unless you have the tore off the bead and just pump it into tne tire you can pretty much forget about the pump, buy a big 100ML syringe (no needle) and some fuel line and use that to suck it up and put it in the tire. I used 5/16" on the syringe end then put that into ¼" fuel like and then fit over the valve stem perfectly and I could measure out how much I used also. But this was put in all 8 tires on a stump grinder that sees some horrible conditions and not any leaks since putting this in. Before all 8 tires had several patches, plugs, and then tubes, removed the tubes put in new metal valve stems 100ml of this in each tire and I sweat ya could shoot the tire with a .22 and it would seal it, the stuff works great other than the pump.

Used this on a set of passenger car tires (mid-sized SUV). Cheap winter tires and rims that the dealership sold us with our new car 8 years ago. Car was always kept in a warm garage and heated parking, but when left outside on occasion, the tires would leak a little air. Not a big deal initially, but as we live in Canada and get some really cold weather, it became an ongoing issue. Over time, the tires lost more air and couldn't even be in the cold long enough to run a small errand before deflating significantly. Various tire shops charged us various amounts to check for leaks; none were ever found. Purchased this and some new valve cores as a last resort before buying new tires. Fully expected the tires to go way out of balance and not be usable on the highway. To my surprise, no balance issues and the tires have held air so far this winter - even leaving the vehicle outside on purpose in cold weather to determine if the tires are still losing air. Very satisfied and this is probably the most cost-effective spend on vehicle repairs I have ever experienced! Berryman saved us from buying a new set of winter tires!

The instructions were clear and easy to follow. Adding the product to my ATV's wheels was straightforward and took about 30-45 mins total to: deflate the tire, remove the valves, add the product, replace the valve, then fill the tire (repeat for 4 tires), then go on a ride to ensure proper distribution. I did this about 3 weeks ago and so far, the product works as intended. I would purchase it again.

Used it on my car which had a very slow puncture that I wasn't able to find. After pouring the stuff in the tire (very easily done by the way) and rolling a little bit it didn't seem to be working but after I went for a real ride of about 35km the puncture was sealed! There are a lot of dirt road around my home and it is regular to have slow puncture so I'll be using it preventively on all four tires. There is enough stuff in the gallon for 2 sets of 4 tires if not more depending of the tire size.

I knocked off one star (wished there was a 1/2 star option) as I cannot comment on how long it will work and I found the pump to be messy. I added this product to aged and leaky pressure washer tires and moving dolly tires a few days ago and they are maintaining pressure. I even noticed a little leakage of the product around a tire bead which indicates where the air was escaping previously. Next job is to add to my ATV tires. Will give me added piece of mind while out in the bush. As mentioned above, it is easy to use and appears to work very well.

I used Stan's for my bicycle tires for several years, good stuff that works, but when my quart bottle finally ran out, a replacement was outrageously expensive: $40 plus shipping. A gallon of Berryman was $43, shipping free. Reviews on Berryman were positive, so I ordered.So far, it's good - more viscous than Stan's, hope that it'll seal punctures better. Cleans up more easily with water. The biggest advantage was price - about 25% that of Stan's. Plan to try it in my motorcycle tires, too.
