I am using Dunlop SP Touring T1 tyres, size 175/70/R13 on my new Wagon R VXL. In my view this size is the best for the stock rims. Besides smooth ride, better handling and braking performance this size also greatly improves the appearance of the car.
The manufacturer claims the tyre’s tread is made of a compound of two types of special polymers due to which it has a long life & low noise and provides good grip, ride comfort and enhanced stability on wet roads.
