TVS Star City Plus tyre size, front and rear

TVS Star City Plus tyre size chart

This is the size printed for current Star City Plus bikes on alloy wheels. Some earlier Star City bikes rolled on wire spoked rims needing tubes, and one or two listings for old bikes show other sizes, so if your bike is older, read the tyre wall before you buy. Spoke rims need a tube type tyre with a tube, while the alloy wheels on the current bike take tubeless ones.

TVS Star City Plus front tyre size explained

Inch sizes are older than the metric style used on sporty bikes. In 2.75-17, the 2.75 tells you the section is 2.75 inches, near 70 mm. No profile percentage appears, since such tyres carry a wall roughly equal to their width. Then 17 names the TVS rim in inches. Together the front reaches about 572 mm overall.

A narrow front like this turns easily in traffic and needs little effort at walking speed, which suits a light commuter. It also has a small contact patch, so keep it properly inflated and replace it before the grooves wear shallow. A bald narrow front on a wet road is the main cause of slips we see on this kind of bike.

Star City tyre size at the rear

The rear 3.00-17 spans 3 inches, near 76 mm, giving the TVS a back tyre roughly 584 mm high. TVS made it a touch bigger than the front since it bears rider, pillion and carrier load, and it does all the driving.

Some owners ask to go one size up at the rear for load carrying. Before doing that, look at the room between the present tyre, the chain case and the swingarm, and ask the dealer whether the new tyre suits this narrow rim. An oversize tyre on the Star City rim wears unevenly and can feel vague. For daily use the stock 3.00-17 is the sensible choice.

Star City Plus tyre pressure

Leave 25 psi in the front for every load; only the back rises, by 4 psi, for a passenger or heavy cargo. Fill with the tyres cold. Underinflated narrow tyres eat fuel and wear their edges fast, while overinflated ones skip over bumps and lose grip on wet tar.

These are owner's manual figures. The pressure printed on the tyre is its limit, not the number to use. Learn to use a pocket gauge in our bike tyre pressure explainer, written for commuter owners too.

Carrying loads on a commuter

Many Star City Plus bikes work as small goods carriers. A gas cylinder, milk cans or a sack of rice add weight right over the rear tyre. Use the pillion pressure for any heavy load, check the rear sidewall for bulges after rough village roads, and do not exceed what the owner's manual allows for the bike.

Overloading a narrow rear tyre heats it up, flattens the sidewall and can damage the rim on a pothole. If the bike regularly carries heavy loads, check rear pressure every week, not every month.

When to replace Star City Plus tyres

• Tiny wear ribs in each groove have become flush with the surrounding pattern
• The rear has worn flat and smooth in the middle
• Small cracks around the sidewall from sun and age
• A cut, bulge or repeated puncture in the same spot: crawl along to a mechanic and follow his advice on replacing it
• The date code shows around five years or more
