Load index / maximum load (IC)
The tyre quality grading is on the tyre sidewall and indicates the maximum load capacity of the tyre.
The tyre quality grading is found in the tyre size coding, for example, 195/65 R 15 91T. It is indicated on the tyre as a code according to ETRTO. The load indexes used at SEAT are listed in the table below with the corresponding loading capacity for the tyres.
