Hey guys has anybody been having trouble with front tires? I bought the bike last year with 5400 mi. The front tire was all scalloped so I replaced it at a local shop. I put about a thousand mi. on last year mostly back roads. This year I take the bike out on the highway for a spell and the front end shakes up and down like a bad shock on a car between 60-80 all is clear above or below. I was thinking wheel weight so I take it back to local shop who said my front end and newer tire :( :( are junk. I had them rebalance the tire and have not been out on it yet. 50 miles/ hour winds and rain. last three days welcome to new england. Thanks in advance for any help.

I had EXACTLY the same problem with a tire on the '97 I used to own. I switched tires, had a rebalance job done, and still the same vibration. I removed the tire...took it to another bike shop, and lo and behold...after they balanced it, it was perfect! I have no idea if you may have the same situation, but during this time I searched for answers. I rebuilt my front forks, new fork oil, new steering head bearings (top and bottom), and still had the same thing. After I took the tire to a shop that actually knew how to balance a tire...I wanted to go to the other shop and tell them that they cannot properly balance a tire. But I didn't...But when asked where to take a tire for balancing, I definately relay my story. This may not be your problem, but I would definately try another shop. By the way..that tire was an Avon Venom. Since them I went with Metzeler 880 Marathon ..and am VERY happy! :D

Thanks I was hoping it wasn't just me. The shop told me to rebuild the front end springs, seals, oil the whole bit. The guy also recomended a compound change to a touring tire etc. One thing I did see is they did not put as many weights on as before. I just finished putting the tire back on now it's 9:30 PM. on a Mon. so I'll try taking it for a spin on tue. if the weather holds. I also took some air out 5-7 lbs. I'll play till I get it right. 8)

I hope it is taken care of...I have tried different PSI's throughout the years on Bosses, and I have found 49PSI to be the optimum pressure for ride and longevity for me. I hope this helps! (I am not sure if it helps, but I always have the shop air the tire up to 49PSI before balancing). I did the whole front end rebuild also, looking for the solution...I just hate for you to do all that when you really don't need to (if balance is the problem). :)

I had the same problem on my bike (when it came from the factory !). A new Avon and VERY careful balancing at a good tire shop made it perfect :) I would not fool around with the forks etc. unless you are 100% sure that the tire is round and well balanced.

The tire must not only be balanced but ROUND. I've had two out of round Avon fronts. Watch the balancing yourself and hold a straight edge to the tire while spinning. No amount of balancing will correct the out of round condition...Joe

Yes the tire is out of round I'm hoping to run it out. It will probably just get worse. I took it out seems better. got to go see yiz.

Yeah....I've tried the "running it out" routine but it never works. I'm afraid a tire change is in your future. Stamford Boss gave me a new tire free when it happenend to me and sent the tire back to Avon....Joe
