That extra width increases the contact area with the road, which can improve dry grip and cornering stability. At the same time, it can add rolling resistance and weight.On the other hand, 245 tires are wider and offer their own advantages. Enhanced Grip: The use of wider tyres enhances traction and stability due to the increased contact patch with the road. High-performance vehicles and off-road applications benefit greatly from this.Tire Tread Width It is common for smaller-performance cars, sedans, and compact SUVs.
