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

Excellent!! Berryman's tire stop leak fixed my nagging slow tire leak. I was getting tired of adding air every time I rode my motorcycle. The tire is as big as a car tire; I couldn't find anything causing a leak; I even replaced the valve stem thinking it might be letting air out but it wasn't. Berryman's did a great job - I put the recommended amount into the tire, aired it up, rotated the tire as recommended to make sure Berryman's got spread around inside the tire; and it's held the correct pressure ever since then. I'm also going to use it on my hand truck dolly tires and wheelbarrow tire which always need some air when I infrequently use them. I'm sold! I recommend Berryman's to solve tire leaks.

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 inflated Tips: 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

Product really works! Small holes and rim leaks sealed up quickly. Especially useful for my riding mower that is subjected to blackberry thorns and the poor quality of the tires developing cracks. Trailer tires were sealed as well. The hose included doesn't actually fit on the pump so a larger diameter, softer one is needed. I recommend this product despite the inconvenience of the hose issue.

Update.. bought another gallon. Works great and here's a few tips in response to those who seem to have troubles... DO NOT remove the tube from the pump after you use it. DO NOT try to empty the tube or clean out the pump. Just pinch it closed at the open end with a metal binder clip. Doesn't need to be perfectly sealed. Product stayed ready to pump for years on a shelf in a dirty unheated garage. No mess, no fuss. And to get it in the tire... take out the core and let the air out. Then JUST PUSH THE PLASTIC TUBE ON THE OUTSIDE OF THE VALVE STEM, hold it there with one hand and pump! Yes, there will be a little on the threads. So what! Wipe it off! Don't complicate things and stop the whining! Stopped leaks on first two old tires on old rims it was used on. One tire was leaking between the tread and casing molding and the other was a bead leak. This alone paid for the product in just the cost of used tires to replace. Not to mention the labor. Less than 15% of the gallon has been used. Used in on road and off road trailers so far, but given the great performance, it will also be used on the rest of our on and off road tires. MUCH better than slime. Very easy to use with pump on the bottle and hose included. Amazons packing was very poor however. No protection for a gallon jug with plastic pump in a cardboard box.

I have uses other tire sealants with mostly good success. However, they were more costly than this one... The green stuff seems to work in snowblower tires until frozen, then it is a matter of three or four time when used before the tire leaks again. I expect this stuff to work in freezing temps. Do not use this in a motorcycle tire that has the pellets inside for balancing as this liquid will clump those together and cause an unbalance act of the motorcycle tube. I did this while riding in the Rockies. It sealed the tire just fine and I got home. It sat for two days and when I rode again to the cycle shop for tire replacement, it was wobbly the whole way. I had to ride under 20 MPH. When the tire was unmounted, they showed me the two clumps from inside the tire. Lesson learned... This has worked well for my lawn tractor, bicycle tires, hand truck, and wheel barrow.

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!

Enough in jug to do 4 large atv tires. Easy to put into tires and easy measure with pump on the jug. A bit messy if you spill some . Put in my tires early fall and tires still up into cold December temps. Time will tell.

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.

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.
