Tyres — 3.7% of failures
Tyres issues account for 3.7% of MOT failures on 1990 Renault R21 Savanna models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures.

Ensure all tyres match the recommended size and load rating.
