Maruti Suzuki Alto Tyre Size

The Maruti Suzuki Alto is India's most ubiquitous entry-level car, and its 145/80 R12 tyres represent one of the most cost-effective replacements in the country's automotive sector. Despite the petite 12-inch rim diameter, the substantial 80% aspect ratio affords a 116mm cushion of sidewall, which provides admirable impact absorption over unpaved suburban lanes and sharp potholes without rim bends. On Alto K10 variants fitted with 145/80 R13 wheels, the rolling circumference is larger and highway cruising stability improves subtly. The featherweight chassis (~750 kg kerb weight) means tyre wear is typically very gentle, with quality sets easily crossing 60,000 km if rotated regularly. The primary performance limitation is wet braking: the narrow 145mm tread can lock up quickly on greasy wet asphalt during sudden emergency stops, making premium high-silica rubber from MRF or CEAT a sensible safety upgrade over unbranded local recaps.
