Consumer reports show that buyers prefer Bridgestone to Dunlop tires. Some have reported instances of Dunlop tire walls breaking down easily, while others are loyal supporters of the brand. I believe it is best to evaluate warranties and the best tires for your needs to come to a conclusion as to which brand is better for you.
There is no much difference between Dunlop tires and Bridgestone. Your choice of tires should be based on the type of automobile. Bridgestone tires are better for off-road and racing, while Dunlop ones are fit for on road drives.
