Sure.ANS 2 - No, it actually isn't that safe. -Snow tires have terrible grip on dry roads and your braking will diminish on wet or dry compared to good summer tires. - -Why do you think they call therm SNOW tires .
Yes. Road conditions validate the type of tires needed for your vehicle but seasons dictate when a change is needed for snow tires or snow tires with studs.
Yes, but slower than you normally drive.
vibrations are not bad for a car it vibrates every time you drive, but for safety i really think that with a flat spot on a tire it is not safe to drive on.
Maybe a little less stability and comfort in riding, but it is sure hard on your tires.
If in the snow with studded tyres, you are probably safe with about 30km/h (about 20mph).
Yes if you take it easy, have good tires, and be able to carry at least one spare. It's a good couple hundred miles of loose gravel.
Yes, if it is in good shape and well kept. A car could have a thousand and be in bad shape and not safe to drive.
Mazda doesnt make the tires
Cheap tyres can be of a good quality which makes them safe to drive on. The air pressure of the tyres will indicate their general lifespan and whether they are still safe to use. The driver's driving style also impacts the tyres. Constant braking and accelerating wears down tyres faster, making them less safe to drive on.
Yes.
It is safe to drive you car for at least one mile after the check engine light comes on.
