 TIRE INFORMATION

Tire Sizes

There are basically three different systems of tire description: Inch system (You are probably familiar with it as tire size readings like 5.00 - 16 or 4.50/S/18), the Alphanumeric System (for example: MT 90-16) and the Metric System (for example: 130/90 - 16). The last numbers are to describe the rim size. Before that number there is generally a dash or one of the letters S, H or V. This is key to speed range: (S) tires are up to 112 mph, (H) tires are admissible for speeds up to 130 mph, and (V) tires for 150 mph and up. Alphanumeric System and Series 80 are describing low-profile tires, which means the height is small than the width and the proportions to the width is fixed. Only in the Standard Inch-System can we find tires with equal width and height which is then a "square-profile".
Metric Alphanumeric Inch-System (Series 90) Inch-System (Series 82)
80/90 ---- 2.75 ----
90/90 MH 90 3.00/3.25 ----
100/90 MJ 90 3.25 3.60
110/90 ML 90 3.50 4.10
120/90 MN90/MP90/MR 90 4.00/4.25 4.25/82/4.40
130/90 MT 90 5.0 5.10
140/90 MU 90 ---- ----
