What are Performance Tires?
After the unveiling of the 2017 Honda Civic Si Prototype, some of you might’ve noticed that it will be equipped with high-performance, Y-speed tires. And now, some of you might be asking… what in the world are performance tires, let alone Y-speed tires? Well, we thought we’d answer those questions in this week’s How’s This Work, by analyzing Performance Tires.

What is a tire type?
For someone who doesn’t know much about tires, you’ve probably glossed right over the tire type when looking into purchasing a new vehicle. Reading something that looks like 235/35R19 Y – which is the designation for the tires that will come equipped on the 2017 Honda Civic Si – can be hard to understand at first. So we thought, for starters, that we would give you the rundown on how to read this.
- 235: The first number, in this case 235, represents with width of the tire in millimetres.
- 35: The second number, after the slash, represents the aspect ratio of the tire. So in this case, the height of the tire is equal to 35% of the width.
- R: The first letter depicts the construction of the tire. The R in this example means the tires were constructed radially.
- 19: The last number is always the same as size of the wheel, as it depicts the diameter of the tire, in Civic Si Prototype’s case: 19”.
- Y: Finally, the last letter represents the tire’s speed rating, with Y being the highest rating a tire can receive.
Tire speed ratings start out at L, which tells you that the tire can withstand a maximum speed of 120 km/h. M, N, P, Q, R, S, T, U and H are the next 9 ratings in order, going up by 10 km/h consecutively, resulting in the H-speed tires able to withstand 210 km/h. After H, you can have V-speed, W-speed or Y-speed, which represent 240 km/h, 270 km/h and 300 km/h respectively.
In other words, the 2017 Honda Civic Si is going to be a fast, fast vehicle. If you have any questions, feel free to give us a call.
