Buying Guide 

Tire sealants are not that complex products. But if you don’t use the correct tire sealant for your lawn tractor, it won’t be able to seal off the punctures. And that’s why you need to make sure that you’re buying the right product. 

In order to help you with that, we have prepared the following guide: 


There are basically two types of tire sealants in the market. And these two types are gel and aerosol. 

Gel type sealants are quite thick and they have high viscosity. And that’s why using this type of tire sealant is a bit tricky. 

On the other hand, aerosol type tire sealants are easy to apply. They come in aerosol bottles and you can accurately apply them on the targeted area. But they are not as strong as gel type sealants. 


Tire sealants are quite affordable. You can easily buy a high-quality sealant on a budget of $10-$20. You’ll find a bottle of 16 oz. to 32 oz. on this price range. 

However, if you want to buy a larger bottle of tire sealant like a 64 oz bottle or a 1-gallon bottle, then you should make a budget of $20-$50. 

Type of Vehicle 

You should remember the fact that tire sealants are vehicle specific. And that’s why it’s necessary for you to make sure that the tire sealant you’re buying is compatible with your lawn tractor. 

Additionally, if you intend to use the tire sealant on other types of on-road and off-road vehicles such as dirt bikes, ATVs, wheel-barrows etc., you have to check their compatibility as well, 

Size of the Bottle 

Always remember, a tire sealant is a temporary fix. If you don’t get it fixed permanently, the tires will eventually start to leak again. But if you intend to keep the tire sealed for a long time, then you should buy a large bottle of tire sealant. 

In contrast, if you want to take your tires to the mechanic immediately, then a small bottle of tire sealant will suffice. 

How Long Does Tire Sealant Last

Lots of puncture = 2 months, No punctures = 7 months. About 5 months, sometimes more, sometimes less, top-up costs less than a tube anyway, and I’d get through a lot of tubes in 5 months! Strip out as much of the gunk as possible.

Final Verdict 

No matter how hard you try, there is no escape from flat tires. If you own a lawn tractor, punctures, bead leaks and dry rots are bound to happen eventually. But if you’ve a high-quality tire sealant like the ones that we have reviewed in this article, then you can solve those issues in a moment. 

And before you leave, we would like to recommend to you our top pick for the title of best tire sealant for lawn tractor. And that honor goes to  FlatOut 20120 tire sealant
