Vibrations are one of the most common symptoms of bad tires. Vibrations that occur at a high frequency and those that cause you or your passengers to feel uncomfortable are an indication that the tires might be damaged, the suspension might have a problem or the alignment might be off.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
If your car tyres are worn or damaged in any way, it affects braking, acceleration, traction, handling, steering and comfort.
Wheel Balance
When your car vibrates every time you drive at 50-70 mph, it is most likely that your wheels are out of balance. The vibrations will emanate from the steering wheel across the seat and through the vehicle's floor.
A vehicle generally vibrates from an unbalanced tire at speeds greater than 45 mph. Some common symptoms that your tires are unbalanced include: Vibration in the steering wheel, floorboard or seat that increases with speed.
Commonly, the car tyre life in India is 5 years. The tyres suffer the wear and tear of ageing from the inside and/or outside. Even if you don't see any tread loss or visible damage on the tyre's surface, it will be safer to replace it after 5 years.
On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.
There is a general consensus that most tires should be inspected, if not replaced, at about six years and should be absolutely be swapped out after 10 years, regardless of how much tread they have left.
The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. This shaking starts at around 50-55 miles per hour (mph). It gets worse around 60 mph but starts to get better at high speeds.
If the brake caliper on a wheel is faulty and causing it to stick, then it can cause car vibrations. In this particular situation, the steering wheel will be what vibrates as you reach about 40-50 miles per hour. The vibrations will get worse as you continue to accelerate at higher speeds.
The most common cause of vehicle shakes at 50 mph or higher is tire balance. Again, transmission or drive lines can cause this, but the tires should be the first thing to have checked.
Driving with unbalanced tires can be dangerous and cause significant wear and tear on the vehicle's suspension system, such as vibrations in the steering wheel and seat, poor handling and stability, uneven tire wear, and increased road noise.
There are a range of reasons why your car is juddering when you accelerate. Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture.
Tires are one of the most common causes of car vibrations. One of the possible issues are out-of-balance tires. Your problems may not be noticeable at slow speeds, but the shaking will intensify as you accelerate to 55-60 miles per hour. The steering wheel, or even the entire car, will start to vibrate.
Old or worn-out tires are one of the number one causes of a shaking vehicle and often the easiest problem to fix when it comes to taking the shake out of your vehicle. Additionally, low pressure in your tires or uneven wear on the tires can lead to a shaky vehicle.
Worn-out tires can also develop bulges and blisters that create weak spots on their surfaces. These can increase the chances of a sudden blowout and can also lead to skidding, hydroplaning, or losing control of your car by reducing the tire's ability to grip the road.
Common causes of why a car feels sluggish when accelerating include dirty mass air flow sensor (MAF), faulty spark plugs, defective throttle position sensor, clogged catalytic converter, faulty oxygen sensor, clogged air filter, and fuel system malfunctioning.
If you begin to feel persistent shaking in your car, it's best that you get to the problem right away before continuing to drive. Continuing to drive with the shaking can result in further damaging parts, ruining your tires, and other costly problems that could be avoided by a quick trip to your mechanic.
