Hawk 250 Tire Sizing Guide

Before I purchased my new Shinko 244 tires I had to do some research because any website you go to buy these tires, it will have bunch of different sizes and numbers and I had no idea what all that meant =). Doing some quick googling and research I found a website that I think explained it pretty well. I’m copying/pasting their content below and will link to the post under it. BEWARE: This website worked for me and the tires I got fit perfectly, please make sure you do your own research if you are getting different tires than the Shinko 244 I got, I would hate for them not to fit and you blame me =(.

The tire sizes for the Shinko 244 tires I got for my hawk are,

Front – Tire Size:3.00-21 51L
Rear – Tire Size:4.10-18 60S

Most dirt bike tires have a set of numbers that indicate the tire width, aspect ration (height) and rim diameter. Sometimes you might see just the tire width and diameter in inches (i.e. 2.50 – 10), and this is common with smaller tires.

80/100-21 Front Tire –

Tire Sizing Example Using an 80/100-21 Front Tire
Using a common 80/100-21 rear tire as an example; the first number, 80, indicates the width of the tire in millimeters. The second number, 100, is the aspect ratio, which is the height of the sidewall in relation to the width of the tread (100% of 80mm). The last number, 18, is the rim diameter in inches. So this tire is 80mm wide by 80mm high or tall and fits a 21″ front rim.

110/100-18 Rear Tire –

Tire Sizing Example Using a 110/100-18 Rear Tire
Using a common 110/100-18 rear tire as an example; the first number, 110, indicates the width of the tire in millimeters. The second number,100, is the aspect ratio, which is the height of the sidewall in relation to the width of the tread (100% of 110mm). The last number, 18, is the rim diameter in inches. So this tire is 110mm wide by 110mm high or tall and fits an 18″ rear rim.
