Tyre sizes and what they mean.
Okay, so you look at your car and discover that it is shod with a nice, but worn set of 185-65HR13’s. Any tyre mechanic will tell you that he can replace them, and he will. You’ll cough up and drive away safe in the knowledge that he’s just put some more rubber on each corner of the car that has the same shamanic symbols on it as those he took off. So what does it all mean?
| 185 |
65 |
H |
R |
13 |
| This is the width in mm of the tyre from sidewall to sidewall when it’s unstressed and you’re looking at it head on (or top-down). This is known as the section width. |
This is the ratio of the height of the tyre sidewall, (section height), expressed as a percentage of the width. It is known as the aspect ratio. In this case, 65% of 185mm is 120.25mm - the section height. |
This is the speed rating of the tyre. |
This tells you that the tyre is a radial construction. Check out tyre construction if you want to know what that means. |
This is the diameter in inches of the rim of the wheel that the tyre has been designed to fit on. Don’t ask me why tyre sizes mix imperial and metric measurements. They just do. Okay? |
More recently, there has been a move (especially in Europe) to adjust tyre designations to conform to DIN (Deutsche Industrie Normal). This means a slight change in the way the information is presented to the following:

Reading news from BTCC(British Touring Car Championship): There was this first ever car powered by bio-ethanol raced in the championship. Wow… imagine that fuel made by farm crops like sugar beet and wheat can really make its way to the race track and soon might be on the road. :p Guess too much hoping for more alternative solution to fill my car. As in this case, bio-ethanol is not only good as being the alternative to fuel petrol or diesel, it also helps to boost the farming industry and in turns benefit to the country economy (of coz, for those country who has farming resource) .
Seeing racing or cars has always been categorize as one of the air-pollution item. Guess after the race, concept as such will have to change, and that racing can still be environment friendly too.
