Will loss of tread In the center reduce rain traction?
I use my bike mostly as an interstate commuter, 60 miles each way. Now the tread pattern is completely gone in the middle but not near the wear bars yet. Is this normal? Should I buy new tires? These have about 6,000 miles on them.

Normal yes, for mostly straight up miles. Is it effecting your traction? Sure it is. Those lines in the tread pattern channel the water away from the contact patch.
I personally think there is a bit more miles left in the tire but if you feel uncomfortable then change them as needed.

That tire is toast IMO.
If you are doing primarily commuting, look into a Sport Touring tire that's designed for mileage and has a harder rubber compound in the center than the edges. Most new tire designs, of all types, are going to multi-compound rubber so they can provide maximum grip when leaned-over but still give reasonable mileage overall. |

Thanks guys. I bought this tire before I found ninjette.org. The dealer said it was a cheap reliable tire. Shinko SR740/SR741.

Go to a motorcycle scrap yard. Look at all the smashed bikes with bald tires. That tire should be replaced.

I'm picky about tires, and have replaces a complete set of 3-year-old car tires (Goodyears even) with less than 40,000 mi before because they had lost too much grip. Tires don't last forever, even if they aren't worn down to the wear bars. The rubber will dry out and you will lose grip even with moderate use. After 4 or 5 years, no matter how much tread is left, a cycle tire should be replaced IMO. |

The rubber will not skid or slide as long as you don't turn sharp-fast or brake hard with the rear. I never use the rear brake and the turns of the interstate have huge radii that put little lateral forces on the contact patches. Hydroplaning is almost impossible for motorcycle tires because the contact patch is too small to trap and hold a continuous and thick layer of water. The real problem is that the thickness of the tire in that zone gets very small; hence, the tire is potentially more susceptible to damage and sudden failure by cutting debris. Once the cords show up, the coefficient of friction is greatly reduced and yes, skids or slides can happen, dry or wet. Each manufacturer must leave some wear bars on the rolling surface of the tire that indicate the minimum recommended. Once any portion of the surface gets flat with those bars, it is time to order new tires.

Alright thanks guys, think my next set might be BT45s. I've only had these tires since October. They were manufactured December 2012

I'd consider hydroplaning as "less likely" on a motorcycle, not "almost impossible". I've done it numerous times. The Coefficient of friction is going to be much less long before the cords show up. |

I ran through a couple of sets of Shinkos on my old Hayabusa and on my Ninja 250. I just bought some for my 300 but have not put them on yet. I never had any problems from them nor any complaints. I got around 7k miles out of rear tires, way more out of fronts. They look good to me and I never had any slipping, sliding, or any other such issues with them. In fact, they truly seemed best on my Hayabusa...they felt soooo sticky on that bike. If you push your bike to its limits then maybe a better set of tires would keep you safer. If your max is at a fun spirited under control pace, then these tires should do you fine....especially for the price.
