The tire size is located on the outer area of the tire wall which contains 3 separate numbers
(ex. 205/55R16). The 1st number is the tire width, the 2nd represents the tire ratio and the 3rd signifies the rim size.
Every tire has a birth date - when the manufacturer stamps the tires with a 4 digit stamp known as a DOT (date of tire) on the outer area of the tire, it stands for the week and year the tire was made. Generally a tire has a six (6) year shelf life at which point it is recommended to be replaced as after expiry it can be a serious safety hazard from tire vibrations during operation to a tire blowout in worse scenarios.
A brand new tire has a 11/32' tread depth which is the measurement between the top of the tire's rubber and the bottom of the tire's deepest groove. It is recommended that once a tire has hit a 4/32' tread depth that it be replaced. It is difficult to pinpoint an exact time frame or tire lifespan because factors influencing the tire such as driving conditions and vehicle wear'n'tear vary.
* Keep in mind tires should also be alternated seasonally. Click here for more info.
Tire rotation ensures that your tires wear evenly, which can extend your tire's lifespan and reduce the need to replace new tires. We recommend rotating your tires after every oil change, roughly about 10,000 KM.
