In slippery conditions, the car’s breaking distance is longer and handling becomes more difficult. Tires are unable to move water, snow and slush out of the way, losing the feeling of road contact.
Consult a tire expert immediately if the tire deflates when in use or if you notice external damage to the tread or the sides of the tire, such as punctures, cuts, abrasion, or uneven wear.
Groove depth is portrayed as millimeters on the tread on Nokian tires. New tires have a groove depth of over 8 millimeters, though often more than 9 millimeters.
While the law does not define tire life or stipulate manufacturing dates, tires can only be considered and sold as "new" if they were manufactured within the last five years. The recommended use/life of a tire is six years and the recommended maximum age is ten years.
The easiest way is to use a penny – place it in the main groove of the tread, in the center with Lincoln’s head upside down and facing you. If you can see all of Lincoln’s head, your tread depth is less than 2/32 and it is time to replace the tires.

Always perform a visual assessment for tires before driving, and inspect more closely every 3-4 weeks. Quick checks can improve driving safety and comfort, and extend the life of tires.
Factors for wear include low tire pressure in relation to the vehicle's weight or load, incorrect wheel steering angles, and worn or faulty shock absorbers. Driving style also plays a large role - sharp braking and acceleration, and turning too quickly, all have an affect. Front wheel tire vehic…
We recommend changing all of the tires at the same time. In some cases two tires can be changed: either both front tires or both rear tires. In these cases, the new tires should be the same brand and model as the old tires to ensure safety and maneuverability.
