It's not allowed. It is a violation of vehicle safety regulations. If you'd get caught out in rain they'd hydroplane real easily, that's why the law require a certain minimum tread depth.
Yes, the traction available form bald tires is very low and unsafe.
Not just Minnesota, ALL country/state driving laws make it illegal to drive on unsafe tires. Bald tires are unsafe because they have poor contact with the road, and are more likely to blow out (explode).
It is illegal because driving with bald tyres does not give you friction when driving on a legal road.Laws vary from state to state.. Most all states have some type of requirements for a vehicles tires,some are more lax than others.Some States require vehicles to have a minimum tread height,meaning you cant drive on bald tires..In the majority of states it is not something a police officer will look for unless of course bald tires were the cause of an accident...(then it can be a fine and ticket).If you are found to have bald tires the majority of time a police officer will issue a repair warning giving you 30 days to get new tires,you must get the new tires and return to the police station/barracks and have an officer sign off on the repair order..You have to check with your local police dept for the laws in your area...
the tyres could blow and you may lose controle of your car
Bald tires can effect anything concerning braking. You will not stop as quickly with bald tires as with tires with tread period. No matter if you have ABS or not.
Bald tires are more likely to skid and slide - particularly if it's wet. It is considered an unacceptable risk to other road users.
With bald tires it can.
If you have a bulge starting in the sidewall you will be able to hear it as it rotates. If you keep driving on it, it will blow... If your wheels are out of allignment the tires will wear un-evenly, for instance go bald on the outside. You may hear this as well.
Depends on where you live.
They are wide to gain maximum traction and bald because they are only used on dry tracks. In wet weather, racing tires with treads are used.
smooth tires or bald tires are illegal as they are very dangerous as they have little grip and you could find yourself in a situation where you need brakes. for eg hurtling of a cliff you could of stopped before or if a tanker swerves into your lane then there won't be a massive explosion. because the tyre has to grip on to the ground so the tyre HAS to have grips on them by law. ---- ----
New tires certainly wouldn't hurt. Your bouncing and shaking is most likely caused by and "impact bubble" or a belt separation on one or more of the tires. Bald tires, result in MAJOR safety issues, including traction, steering, handleing, stopping, and if a blow out occurs, you will be throwing rubber and steel shrapnel into everyone else's path that's behind or beside you. Get those tires replaced!
