My tires feel like they are slipping when i take off on the road, when they shouldn't, so i was wondering what brand of tires is best and whether or not my tires are in need of a change.

 

Im running those new "Dunlop Qualifers"...ive got a 160/60/17 and a 120/60/17....great tires. I use to have the older model tireson my bike (the Dunlop D208).
.....when u go to buy new tires buy the front and rear and put them on at the same....its good to have them wearing at the same rate.
I paid 209.99 for my Dunlop Qualifier (Rear and Front tire) got them through www.motosport.com

 

Have you checked your tyre pressures? If they are only slightly down it can really effect the way the bike handles, I am running Dunlop 208rr which seem a good tyre, I have done about 2500 miles on mine and they still have lots of life left in them.

 

How old are your tires? After a few years they can dry out and get less sticky, even if there's plenty of tread left on them.

You can do a search of old threads to find out what people have written about different tires.
