The lifespan of street tires varies depending on several factors such as the type of tire, driving habits, road conditions, and weather conditions. On average, most quality street tires last between 40,000 to 60,000 miles, or approximately four to six years, although this estimate can vary depending on several factors.
Driving habits, such as aggressive driving, hard cornering, sudden braking, and frequent high-speed driving, can shorten your tire's lifespan dramatically. Also, driving on rough or uneven roads, or in extreme weather conditions, such as hot summers or freezing winters, can also wear down your tires more quickly.
Regular maintenance can also affect tire longevity. Properly inflated tires, tire rotations, and wheel alignments can extend the life of your tires and ensure uniform wear.
It is important to note that while street tires may still appear to have sufficient tread depth, their performance can decline significantly as they age, which can compromise safety at high speeds or during sudden maneuvers. Therefore, it is recommended to replace street tires after six years, regardless of their remaining tread depth.
