The bulky full-sized spare tire has been eliminated from the majority of new cars by automakers in an effort to increase fuel efficiency and cut costs. A Consumer Reports poll found that less than one in ten cars now had a full-size spare tire. Although more than half of new cars come with temporary space-saving spares, you’ll need a sealant kit for the remainder cars that don’t have any tires inside.
There are three different kinds: liquid stand-alone sealants, cans that mix sealant with air pressure for partial inflation, and deluxe packages with an air compressor that can fully inflate the tire. Bicycle tires, pool toys, and sports balls may all be inflated using the compressors, which are also available individually. The entire kits are definitely your best option if you have the money for them. The tire pressure monitoring system in your newer car won’t be harmed, according to the sealants (TPMS).
Even if your automobile has a spare tire, it’s conceivable that it has lost some of its air over time. Additionally, if you reside in a region with many rocky roads, you might consider using tire sealants as a preventative precaution because they can add another layer of defense against minor punctures. The top choices in three categories are listed below.

List of The Best Tire Sealants in 2022 on Amazon.com
#1 Tire repair tool AirMan ResQ Pro+
This package is for you if you trust automakers, at least when it comes to inflating tires. GM, VW/Audi/Porsche, Mercedes-Benz, and Peugeot all utilize or advise it. A 12-volt compressor is included in the kit, and it plugs into your power outlet. The firm claims that when the tire has been professionally patched, the 15-fluid-ounce can of “eco-sealant” that the compressor is attached to will wash off with water. The kit can repair holes up to a quarter inch in diameter and restore your tire to its original pressure. It’s useful to have a nighttime LED light. A storage bag, an inflator, and numerous adapters are included with the set. There is also a less expensive kit that needs some assembly.
What We Enjoy:
- Everything you require to resume driving (and fully inflates the tire)
- No valve stem removal and an OEM (original equipment manufacturer) product
- The compressor can handle the task.
What We Do Not Like
- expensive in comparison to alternatives
- Never travel more than 120 miles or at speeds higher than 50.
- If the sealant is left to cure, it will be more difficult to remove.
#2 Slime Repair Kit for Flat Tires
The Slime kit’s design is comfortingly step-by-step and actually walks inexperienced customers through tire inflation. The kit already includes the sealant. Attach the nozzle to the tire stem, plug in the 12-volt power, select “air plus sealant,” push the green “on” button, and then use the really helpful built-in gauge to inflate the tire to the appropriate pressure. Slime sealant works well on holes up to 1/4 inch in diameter. Removing the tire’s valve stem is necessary for some Slime sealants, which is a bothersome procedure; the company’s Thru-Core Emergency Tire Sealant does not.
What We Enjoy:
- tire pressure gauge built-in
- An eight-minute work is ideal.
- You can use a compressor for unusual jobs.
What We Do Not Like
- Some slime sealants demand removal of the valve stem.
- Air could leak from the screw-on connector.
- Replacement Costly slime cartridges
#3 Instant Tire Inflator and Sealant for the Road
The trick with a sealant like this is to think of it as a cheap emergency stop-gap solution to get you to a repair shop without driving on a flat and doing irreparable sidewall damage to the tire. The tire will momentarily be sealed against further leaks after receiving a partial inflation from the sealant. The benefit is that it’s inexpensive—$20 for three emergencies. The product may be washed inside with water and is not flammable.
What We Enjoy:
- A very good value
- to prevent spending a fortune on new tires.
- simple cleanup
What We Do Not Like
- TPMS ambiguity
- Not going to go you very far.
- The can’s back states, “If vehicle has tire pressure sensor technology, do not use this product,” despite the product being touted as TPMS-safe.
#4 Tire sealing compound from Berryman
It’s effective stuff. It has the benefit of staying liquid forever, which makes cleanup simpler. It resists punctures and leaks caused by nails, thorns, and other sharp things well. It can be used as a preventive by incorporating corrosion inhibitors. “Stops leaks before they happen,” the label declares. If there is a negative, it is that it requires positioning the tire and using the (provided) tool to remove the valve stem before use.
What We Enjoy:
- Cheaper alternative
- Possibility of preventative usage; suitable for lawn tractors
- avoids making a mess
What We Do Not Like
- need a separate compressor
- Some users report variable outcomes.
