Could be several reasons but the first one that comes to my mind is to have the tires balanced.
Cars vibrate.
If the tires are properly balanced plug tires should not cause a vibration.
If they are normal cars there will be 104 tires
Not all Altima's vibrate. If the car is vibrating, it may mean that there is something wrong with the tires.
Since cars were first made tires were always rubber.
Bad tires or out of balance tires or driveshafts. Have it checked out.
A burn out will ruin tires on race cars by burning up the rubber. The rubber of the tires will get worn from the friction of the pavement causing the tires to tear.
Tires need ballanced!!!
Many European cars use 14 inch tires.
through the tires
Tires or the road.
It is possible that the tires are out of balance. Any reputable tire dealer can check the balance for you.
