are flat spots on tires dangerous?
153880
Tires are meant to be round, so obviously flat spots damage the tires' functionality. Tire flat spots are dangerous because one or more flat spotted tires can cause a shimmy or harmonic vibration that makes it difficult to steer your car. They might even cause tire failure and accidents.

No, fix a flat won't ruin a tire, but I should warn you about something. Every car since 2008 or so has tire pressure sensors in the wheels. These sensors do not do well with fix a flat clogging them up. In fact, it ruins them.

A repair too close to the sidewall may cause a blowout if you hit a curb just right. If the nail is toward the center of the tire, you're in luck because it can be patched. I've driven close to 3 weeks with a nail in the center area of the tread.

Yes, lower profile tires should be inflated to a higher pressure since there is less distance from the tread to the rim. Hitting any large pothole or obstacle can damage your rim.

The flat tire "acts as a cushion," according to Car Talk, protecting the rim of the wheel. You can therefore drive — again, at a slow speed — for hundreds of yards before your wheel is damaged, "though your tire may no longer be any good."

You could damage your vehicle As the tire itself brakes apart, separates from the rim and begins to flail around the tire wheel, important (and expensive) components such as brake lines, rotors, fenders and suspension parts are apt to get seriously damaged.

Furthermore, while standard tires can often be repaired, run-flats are much harder to fix. In fact, Pirelli specifically does not recommend you repair a damaged run-flat, since driving on the tire with little to no pressure can wreak havoc on the internal structure, rendering them unsafe.

A bent rim can be obvious to the trained eye. The rim rests on the outer edge of your tire and maintains the air seal between your tire and your wheel. ... At best, an untreated bent rim can cause tires to leak air over time. At worst, you're looking at a flat tire or a blowout.

Since the sidewalls have less give, run-flat tires tend to pound harder over bumps than other tires. The latest models have improved in ride quality, Rogers says. Still, the most comfortable run flat may not be able to match the most comfortable conventional tire when it comes to ride quality.

However, a bent or damaged wheel can be very dangerous, and expensive. Bent rims can pinch and pop your tires, leading to blowouts. They can also cause mechanical issues, and problems with the handling and control of your vehicle, which can lead to dangerous situations.

Driving on under-inflated tires is dangerous. ... If tire pressure is too low, too much of the tire's surface area touches the road, which increases friction. Increased friction can cause the tires to overheat, which can lead to premature wear, tread separation and blowouts.

Nearly two-thirds of vehicles are not road-worthy because of overlooked tire service. Even worse, more fatal collisions occur, especially during the winter months, due to missed inspections Noise, vibrations, hydroplaning, and accidents--this is what could happen if you don't rotate your tires.

Cracked tires are no good—and, often, you'll notice sidewall cracks in your tires first. Sidewall cracking is dangerous because it reduces a driver's ability to handle dramatic increases in load when taking corners and increases the possibility of a tire blowout. Repairing sidewall cracks ASAP is always the best idea.

A major problem resulting from hitting the curb is throwing your car's suspension out of alignment. This will lead to uneven tire wear in as little as 200 miles. Your tire may also have suffered damage to the sidewall that could lead to a possibly dangerous blowout.

GET YOUR TIRE BALANCED: While unbalanced tires will not "cause" death wobble, they can instagate it and, if they are still off, it will make it harder to identify the actual source.

Don't go far. You should never attempt to drive any further than a couple hundred yards on a flat tire, even if it isn't completely deflated. This may not be enough distance to get you to an auto garage, but you can at least creep along until you're away from the hazards of the highway.
