Tire size explained: a visual breakdown

Every number and letter on your tire is there for a reason — once you know what they mean, you’ll never look at tires the same way again.

In this video, I break down each part of the tire code, including:

1) Tread width, aspect ratio & rim size
2) Load index & speed rating
3) DOT codes & manufacturing date
4) UTQG ratings (Treadwear, Traction, Temperature)
5) M+S vs 3PMSF (Winter safety)
6) Rotation direction & asymmetric tire markings

This video isn’t just for car tires — it’s for anyone who uses tires.
Whether it’s a bike, car, or truck, understanding these basics can save you from unknowingly using the wrong tire — which can lead to breakdowns or safety failures.
