5.2.1 Setting using tyre table
The common types of tyres are listed in the tyre
table. If your tyre type is not listed, we recommend
entering the wheel size manually.
The values given in the table are approximate
values. These values differ according to brand, tyre
height and tyre profile. This can consequently also
lead to discrepancies in the distance measured
and the speed shown.
