Nearly every new car used to come with a spare tire but these days it’s no longer standard.
Consumer Reports tested a few products that they say offer easy solutions.
The group tested Slime Safety Spair along with other tire-sealant compressor kits, as well as aerosol cans that promise a quick fix.
To test, they outfitted a car with 15-inch, all-season tires.
They punctured one of the tires with a small nail and put the products to work.
All the aerosol cans were able to seal the small hole and inflate the tire, which kept going for more than 100 miles.
However Consumer Reports found all the cans had difficulty with larger holes.
“It can explode so that kind of limits its use,” Consumer Reports’ Gene Peterson said. “You’re not going to keep it in your car. You’re probably going to keep it at home and when you need to use it, it’s not going to be with you.”
The compressor units are more expensive but can be safely stored in your car.
You plug the compressor into your car’s power adapter and attach the sealant canister to your tire.
All the compressor kits fixed even larger holes.
Consumer Reports found the $80 ContiComfortKit works the fastest with enough sealant to repair a wide variety of tire sizes.
Consumer Reports cautions the tire repair products are just a temporary fix.
As soon as you use them, get to a service station to have the tire inspected, repaired or replaced.
Also, be aware none of these products can repair large punctures.
Officials said they should never be used to fix punctures in the sidewall of the tire.
