Upsizing is the practice of replacing an automotive wheel with one of a larger diameter fitted with a new tire of
lower aspect ratio so that the new tire has the
same diameter and circumference as the original
tire to prevent any changes in speedometer
accuracy, torque and traction control, while
reducing sidewall flex and--generally--increasing
cornering ability.
Permissible tolerance +/- 3%
*All upsizes are subject to body clearance

The correct tyre upsize has to be complimented with the correct Rim Upsize for optimal performance. For more details walk into Premji's TyreStore
