can anyone tell me if the Dunlop Sport tires are any good I am looking at buying some.

 

Dunlop makes a lot of different tires with Sport in the name. Some of them are good, some of them aren't. (The same is true of most other brands.) It's also possible that some other brand may be better for your needs.

Why don't you tell us what kind of car you have (year, model, version), what size wheels you have, and how you plan to use the tires (daily driving, track/autocross, dry, wet, snow, etc) and we can give you a more specific recommendation for your needs.
