What do the numbers mean on the sidewall of the tire?

I want to get new tires for my motorcycle and I was wondering if anyone tell me what the numbers mean on the sidewall of the tire. Currently, on my tire I have the numbers 130/90HB-16. I know the number 16 stands for the rim diameter, but about the other numbers? What importance do they have when riding a motorcycle?

The numbers on the sidewall of a tire can be difficult to de-code if you’re not familiar with their significance. I had problems too when I was trying to understand their importance. Based on the numbers you mentioned 130/90HB-16 stands for the tire width, aspect ratio, speed rate, construction type, and the diameter of the rim. So for your tire numbers, 130 indicates the tire has a 130 mm tread width. The number 90 is the aspect ratio, which is the sidewall height. This is listed as a percentage, so for a 130/90 the aspect ratio/sidewall is 90% of the tread width. Lastly, the number 16 is the rim diameter.

The letter H stands for speed rating, which means your tire has a max speed of 130 MP. The next letter stands for the type of construction of the tire. Your tire has the letter B, which stands for bias ply instead of radial instruction, which would have the letter R.
