Tire calculator

Method 1 - Tires that have to be compared:

		Diameter:	Circumference:
Current tire: / R		mm	mm
Desire tire: / R		mm	mm
Difference:	%	mm	mm

Speedometer shows 80 km/h - Real travel speed: km/h

Method 2 - Calculation for the optimum rim width for a given tire size:

/ R => Min. x Max. x

Method 3 - Calculation for the correct tire size by changing the rim width:

1.	Current tire size:

2.	Min. criteria of the new tire:

3.	Max. criteria of the new tire:

4.	Specifies of the max. deviation [%]:

Possible tire sizes:

Please note that you maybe will not find all possible tire sizes here.

We recommend only a deviation of max. 2,5% of the tire size. The legislation allows up to 7%, but only 3% for cars with ABS.
