Buying Guide for Tire Sealant for Lawn Tractor
Our fix a flat tire sealant reviews might have you feeling a little confused if you don’t know what you’re looking for. The price range and capabilities of tire sealants vary greatly. So, here's what to keep in mind when looking for the best tractor tire sealant.
Sealant Type
The first thing you need to know about tire sealant is that it comes in two different forms: aerosol and gel. Each has its own benefits and advantages and offers different purposes:
Aerosol
All single-use tire sealants come in aerosol form. Aerosol-type sealants are easy to apply from spray cans, and the application is usually quite accurate. When you apply an aerosol sealant, it inflates a deflated tire by coating the inside of the tire to plug the hole.
Aerosol tire sealants are good to have on board for tire puncture emergencies. However, they provide a very temporary solution and are only meant to be used to drive short distances.
Gel
If you're looking for a stronger tire sealant, then you need to buy a gel formulation. Thick and viscous gel sealants offer a more substantive plug, but this also makes them more difficult to apply (and it might require you to use extra equipment). However, a puncture that has been fixed with a gel sealant will definitely last longer than one done with aerosol.
Compatibility with Tractor
As we mentioned before, every tire sealant is made to be used with a specific vehicle. As such, it's of utmost importance to double-check whether the sealant you're buying is compatible with your lawn tractor. For example, Slime makes a separate sealant for tires with tubes; so if your tractor has tubeless tires, then you know what not to get.
Frequency of Use
Unfortunately, some of us expect our lawn tractor's tires to be punctured more easily than others. There's no shame in that-- taking care of a lawn is difficult! However, this means you'll have to buy tire sealant according to your projected needs. Even without frequent punctures, you might be looking to patch multiple tires with one tube of sealant or resealing the same puncture repeatedly. So look for a sealant that can be used multiple times.
Container Size
It's important to understand that tire sealant is not a permanent solution for a puncture. So, if you don't think you'll be replacing your punctured tire or contacting a mechanic, you'll have to use a larger amount of sealant to take care of the puncture. So, it's better to buy a large container to have the required amount ready in one go. However, you should also strive to ensure that your chosen sealant is suitable for repeated usage.
FAQs for Tire Sealant for Lawn Tractor
How do tire sealants work in fixing punctures?
When you apply tire sealant to a puncture, the leaking air pushes the sealant through the puncture. The liquid component of the sealant falls out while the fibers come together to form a blockage in the puncture.
Does applying tire sealant prevent punctures from happening?
This depends on the type of sealant you buy. While some are targeted to fix punctures, others can act as a precautionary measure.
How do you apply tire sealant?
Typically, it has to be injected through the valve into the tire. This is a good instructional video on how to use Slime tire sealant.
Does tire sealant extend the life of the tire?
It does. However, tire sealant should never be viewed as a permanent solution. Furthermore, for really bad punctures, it's best to replace the tire entirely.
Should I buy aerosol sealant or gel sealant?
Aerosol sealant is only for emergencies and for minor punctures. Gel sealant, on the other hand, is more difficult to apply as it might require the help of tools or equipment.
How much does lawn tractor tire sealant cost?
Sealants are available in a wide price range from $10 to $60. It depends on the quantity and purpose.
