What This Size Means
155 = tread width in millimetres. 80 = aspect ratio, meaning the sidewall height is 80% of the tread width (124 mm). R = radial construction (or bias-ply if dash-indicated). 13 = wheel rim diameter in inches (330 mm).
Editor's Technical Insight
The Tata Tiago transformed the Indian compact hatchback segment by introducing mature European-inspired ride dynamics, a sturdy bodyshell, and composed high-speed manners. On mid and top XT, XZ, and XZ+ variants, the stock 175/65 R14 tyre size strikes an admirable compromise between low rolling resistance and assured highway grip. Entry-level XE models fitted with 155/80 R13 tyres offer a tall, forgiving 124mm sidewall cushion, but the narrower tread tends to squeal under emergency braking from 80 km/h. Enthusiast owners seeking a more planted stance often upsize to 185/60 R15 (the factory specification on the sportier Tiago JTP and Tiago NRG crossover variants), which fills the wheel wells handsomely and sharpens steering response. For Tiago iCNG and Tiago EV models, the extra weight over the rear and floorboard means tyre pressures should be monitored weekly: keep front tyres at 32 psi and rear tyres at 32-33 psi to avoid premature tread shoulder wear.
