new tire shake

i just put two brand new tires on my bike yesterday. I took it out for a ride and the bike seems to shake anywhere from 30-55 mph. Could the tires be out of balance? the shaking seems to be coming more from the front. any suggestions?

btw.. the tires were put on by a so called professional motorcycle mechanic

I am almost sure it is a tire out of balance. Did you watch the tire change over, or just drop them off and pick them up again? Would you recognize when he was balancing the wheel? Is there a mention or charge for balancing on your reciept? I would take the bike back as soon as possible and get the problem solved.

The balance could be off but it almost sounds like they forgot to tighten something up correctly.

Some tires have arrows that must face the dirrection of rotation, otherwise they will shake too....

And contrary to Amsoilz post, just about any tire needs to be balanced. In this realm "close" is not close enough. Even if the tire is balanced the maker has no idea how much your wheel is off.

Take the bike back, explain the problem and make them fix it.

I never noticed any vibration after my tires were balanced, but I added RideOn within a few hundred miles. RideOn is supposed to help balance tires as well as protect against punctures. If further balancing doesn't fix it, might try RideOn.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Sounds as if The pro mechanic didn't get your front tire balanced correctly, take it off and run it back to him and watch him spin it up again.

Is there any weights on the wheel or any marks on the wheel where weights had been, is the little yellow dot on the tire at the valve stem?

If there are weights and they look like they haven't been moved, he didn't balance the tire.

Some tires are built well enough that they don't need balancing. Kawasaki did a great job with the balance of alloy wheels on are bikes.

A friend of mine owns a bike shop. He has a computerized wheel balancer, I was watching him one day this Spring, doing a ton of tires. What I noticed was the alloy wheels took little or no weights, but spoke type wheels always took some weights, sometimes allot, to get them balanced.

I, like Amsoil man did not have to add any weights to are Kenda Kruz tires. The stock Dunlap's that came on my bike were way out of balance, I could not believe the amount of weights on the rear wheel. But in their defense, tire technology has came along way since 1985.
