Car tires are made to withstand a variety of road conditions and materials, but glass is not one of them. If you happen to hit a patch of glass on the road, it's best to pull over and inspect your tires for any damage. Even if there doesn't appear to be any punctures, the glass could have weakened the structure of the tire, making it more susceptible to blowouts at high speeds. So, while car tires can technically withstand glass, it's not advisable to drive on it for long periods of time.
