Tata Manza tyre size for all variants

Tata Manza tyre size by variant

The rim is a 5.5J x 15 on the factory wheels. Some early Aqua and Aura cars were listed with alloys, so the wheel type varies, but the tyre does not.

Decoding 185/60 R15 for a family sedan

Start with 185: millimetres of tread. Next, 60: a wall height that is 60 percent of the tread, roughly 111 mm. Then R for radial plies, and 15 for wheel inches. End to end, the tyre measures close to 603 mm.

For a sedan built to carry families between cities, this is a balanced choice. The wall is tall enough to soak up rough patches, and the 185 width keeps steering light in traffic. A wider tyre will grip a little better, but it will also steer heavier and can cost some mileage.

Upsizing the Manza: what the numbers say

Tata only ever fitted 185/60 R15, so any change is outside the factory plan. Owners commonly try these:

Of these, 195/60 R15 is the gentlest step and suits the original rim. The other two push right up against 3 percent: your speedometer will show less than true speed, and listen for the liner rubbing at full lock. Match the old load rating, and keep the insurer informed. Run your own choice through the tyre size calculator.

Pressure on an older Manza

Tata's cold figure, plus a raised one for five occupants with luggage, is printed near the driver's door hinge and in the handbook's pressure table. Stickers fade on old cars; any Tata workshop can look the value up. Ignore the bigger number moulded on the rubber, which is merely its limit.

Older sedans often have slow leaks from corroded valve stems or alloy rims with a little oxidation around the bead. One corner that keeps going flat usually needs a fresh valve or a cleaned bead seat. See tyre valve for details.

Age matters more than tread on this car

A Manza that mostly sits in a society parking can keep deep grooves while its rubber quietly goes stale. Old compound turns hard, splits finely and loses wet grip. Locate the four digits stamped near the rim; the opening pair is the week, the closing pair the year. Retire any tyre beyond five or six years, or earlier once hairline cracks appear. The date stamp explainer has pictures.

Spare wheel and the boot

Lift the boot floor: the spare there is frequently the oldest rubber on the car. Check that it matches 185/60 R15, holds air and is not cracked. On a used car, the previous owner may have left a mismatched spare; that is fine to reach a puncture shop, but not for long distance use.

Other sedans and hatchbacks

If you are replacing the Manza with a newer car, or run one alongside it, our pages on the Dzire and the Tiago cover two popular small cars. A Manza 185/60 R15 rarely suits those, because both run different rims. Keep each car's spare with that car. Older and current models alike appear on our passenger car size index.
