Tire irons are metal devices used to remove lug nuts and separate tires from rims. They were used to remove tires from rims without damaging inner tubes before tubeless tires. They are still used in auto repair shops to replace old tires with new ones. The devices that come as standard equipment on most cars are actually spanners, but people often refer to them as tire irons.
As any driver knows, putting a new set of tires on a car requires the use of a tire iron. Essentially a metal device used to remove the lug nuts that hold the wheel in place, as well as separate the tire from the rim, tire irons are part of the standard tools almost every auto mechanic has. on hand for your use. Here’s some information on tire irons and how to use them properly.
In the pre-tubeless era, tire irons were a set of two metal bars used to remove a tire from the rim without damaging the inner tube. One end would include a tapered end, while the other would feature a lug wrench for removing the lugs that hold the tires in place on the vehicle. After loosening the nuts, the car can be safely raised with a jack. One of the tire irons would be used to slide between the edge of the tire and the rim. Once in place, the second would be used to work around the perimeter of the rim, lifting the rim up and over the rim. Once the tire came off the tire, it was relatively to remove the old one and then replace the tire with a spare.
While tire irons are no longer used on the road to change tires, many auto repair shops continue to use them when replacing old tires with new ones. The process is basically the same as in previous years. The car is raised and the lug nuts are loosened and removed, allowing the tire and rim to be removed from the vehicle. The tire is locked into place on a tire dolly, where irons are used to remove the old tire from the rim. Once the new tire is placed around the rim, the tire iron is used to move the rim edges back into place around the rim, and the tire is inflated. At that point the tires and rims can be put back on the car wheels and secured with the lug nuts.
Many people refer to the devices that come as standard equipment on most cars as tire irons. However, those devices are more properly known as spanners. In general, the general public makes little distinction between the two implements, so it’s not uncommon to hear of someone changing a vehicle’s flat tires with a tire iron.
