TYRE UPSIZING – BENEFITS, RISKS & HOW TO CHOOSE THE RIGHT SIZE FOR YOUR VEHICLE

Tyre upsizing is a popular upgrade among car owners who want better handling, more road grip and a sportier look. Upsizing means changing from the stock tyre size to a wider tyre or larger rim while maintaining the correct rolling radius. The key rule in tyre upsize is keeping the new circumference within ±2% of the original size. Exceeding this limit causes problems such as ABS malfunction, inaccurate speedometer reading, poor mileage and suspension stress. A tyre upsize calculator helps compare rolling radius, tyre width, rim size and percentage difference to ensure the new size is safe. Wider tyres increase vehicle stability, cornering control and braking performance, especially on highways and wet roads. Vehicles with larger tyres also look more aggressive, fill the wheel arches better and feel more planted at high speeds. However, incorrect upsizing can cause rubbing issues, reduced ride comfort and faster shoulder wear. Drivers choosing a +1 or +2 upgrade need to reduce sidewall height to match the rolling diameter. For example, shifting from 185/65 R15 to 195/55 R16 is a safe upsize because the difference remains within tolerance and maintains correct wheel geometry. Tyre upsizing supports stronger road grip for SUVs, sedans and hatchbacks, making cars like Creta, Baleno, Innova and Thar feel more confident. Before purchasing, drivers must check load rating, speed index, rim width and offset to avoid vibration and steering imbalance. When done professionally at a tyre shop, upsizing improves handling, braking bite and cornering grip without harming mileage or safety. In simple terms, tyre upsizing is the easiest way to enhance tyre performance and vehicle stance, provided the diameter change stays within the 2% guideline.
