Tire Weld
AKA: Tyre Weld, Spray Repair, Tire Filler
Products that you spray into your tire can leave your wheel in a mess. Consider them a last resort. Results vary widely with these products and they cannot necessarily be relied on to provide a safe and lasting fix.
Introducing solids to your tire will alter the balance of your wheel. If using this type of product, be sure to drive carefully and more slowly than usual, as greater speed equals greater exaggeration of wheel imbalance, which can lead to handling issues, especially in less-than-ideal road and weather conditions.
A spray filler that you inject into your tire. After use, wait a few minutes for the spray to set before pumping up the tire. The pressure should force the spray towards the puncture hole, where it will be trapped, preventing air from escaping.
This is definitely a temporary fix. Please be careful with this type of product, as the claims are often wild in comparison with the real-world results.
