Dunlop GPR300's are fairly inexpensive.
I get this what the best tire for me question alot. It's very similar to the what's the best motorcycle engine oil for me question.
Short story short, there's no best tire for you. All your tire choices are all just different flavors of good choices. As long as you get a name brand tire in the correct sizes you did good.
If you want longer lasting tires then choose a sport-touring tire...
AVON Storm, BRIDGESTONE T31, CONTINENTAL Road Attack, DUNLOP Roadsmart, METZELER Roadtec, MICHELIN Pilot Road, PIRELLI Angel
If longer lasting tires not a priority then choose a sport tire...
AVON Ultra, BRIDGESTONE S22, CONTINENTAL Sport Attack, DUNLOP Qualifier, METZELER Sportec, MICHELIN Power, PIRELLI Rosso
