Welcome into the World of Westlake
Tyre Upgrade means increasing rim diameter without changing tyre overalI diameter and the trend in development of low aspect ratio. The upgrade improves a tyre's sporty and braking performance.
Without any particular reason, please do not change the tyre overaIl diameter easily. The alteration of the tyre overall diameter will cause misreading of speedometer or mutual interference between tyre and other parts of vehicle.
PIease determine the width of a tyre in accordance with the specific width of vehicle. If the width of the entire tyre is increased overIy, it wiII cause mutual interference between tyre and other parts of vehicle, even heading out of the tyre from bodywork which will initiate danger.
Notice the Ioad index of vehicle when you upgrade the tyre. There is rule to the weight which the tyre can bear (Ioad index) for each size.
