Ražotāja noteiktā riepas maksimālā kravnesība tās ekspluatācijas laikā.
Kravnesības un ātruma indeksi ir norādīti uz abām riepas sānu malām. Kravnesības indekss - ražošanā noteikts standarts, kas nosaka automašīnas riepas maksimālo nestspēju. Zemāk ir sniegts saraksts, kas norāda dažādu veidu riepu kravnesības indeksus un tiem atbilstošus ātruma indeksus. Nemarķētām radiālām riepām atļautais ātrums ir līdz 110 km/h (68 mph). Diagonālo kordu riepām atļautā ātruma robeža ir 100 km/h (62 mph). Atjaunotās riepas, ja tās nav citādi marķētas, var sasniegt maksimālo ātrumu līdz 110 km/h (68 mph). Īpašām riepām, kas izmantojamas smagos apstākļos, uz riepas sānu sienas jābūt norādītam atbilstošam ātruma ierobežojumam. M&S riepām ātruma indekss ziemas apstākļos ir zemāks, nekā tas būtu iespējams konkrētajam transportlīdzeklim. Atsevišķās valstīs pastāv obligāta prasība, lai autovadītājam redzamā vietā tiktu novietota uzlīme ar riepas maksimāli pieļaujamo ātrumu. Riepu izmantošanas laikā noteikto ātruma ierobežojumu nedrīkst pārsniegt. Ātruma indeksu sistēma attiecas uz visiem riepu ražotājiem.
