 | Understand the code on all tyres. An Esteem tyre will have a code on the side reading 155/80 R 13. This means 155 mm tread width. An 80% aspect ratio meaning the ratio of height to tread width. Radial and 13 inch wheel rim diameter. Do not worry about the letters 84S as these define the maximum load and speed ratings which in this case means 500 Kgs and 180 Kmph. Car makers carefully calculate the right tyre for your car so it is not wise to deviate too much from their recommendations. | | You do need to ask whether the tyre carcass is made from polyester fibre or not. As polyester is the strongest fibre, less fabric is needed so the tyre can be lighter and have thinner walls. This means a significantly softer ride with no sacrifice to safety. Many dealers themselves are unaware of this Bridgestone, Goodyear and JK Tyre radials are polybelted among the Indian brands at present. |
| Check if there is are steel belts because they not only reduce punctures but keep the entire tread flat on the road resulting in much better traction and cornering. | | Look at the tread pattern. Don't just be different. If you need traction for some rough or slippery roads, a tyre with well separated lugs is better. City slickers might however prefer a tread with the lugs close together because this will ensure more silent running. |
| Don't worry too much about tyre life. Most new radial tyres tend to last very well for around 40,000 Kms or more depending on the car and driver. Nevertheless, you will probably want to change them before they really need a change. | | Check the prices from several dealers as prices can vary quite a bit. Don't rely on the advice of your tyre dealer. They may be keen to sell you an expensive imported tyre that may not be suited to your car. Some dealers also like/dislike a particular brand and can be prejudiced. |
| | | | Don't forget to get your wheels balanced when new tyres are fitted. Old wheel rims often need a little correcting. Tyres should be re-balanced every 5 - 10,000 kms because some of the rubber gets scuffed off. |
