tire wear
« on: April 30, 2010, 05:40:00 PM »
here's a good video on why tires wear the way they do.

my front tire gets bumpy, leading edge lower than trailing edge.
I've changed the fork oil but seems from this video I still have a valving problem.
My forks are both rebound and compression adjustable so perhaps I can adjust it out.
I'm hoping for that. :)

It last over 2 hours I think it was. He does give some street tire answers but
what I really would like to know is how I'm going to correct my front tire
wear problem. ???

Seems my rebound is screwy which causes the lumpy wear. But so much trial
and error to get it right seems to be the only answer the video offers.

front tyres never wear even,road camber and "round abouts " if you call them big circular go a bit right to turn left things,if your getting decent milage and the tyre is sound,i wouldnt try and fine tune it out,tyres wear because they steer/stop you car or bike,i think this is whats happening,i always have had the lead/trail edge fluffy difference,its normal,the front tyre on bikes wont show wear patterns like a car.

we've so many twisties it's probably as you say. It's a fairly soft sticky tire that
wears fast anyway. The last two fronts have been
Dunlop Sportmaxes and I'm fixing to run a set of Perelli Angle ST's next.

tyres are a personal choice,a lot like beer!i use the bridgstone bt45 on the front and the bridgstone spitfire on the rear,not a cheap tyre ,not expensive either,but a good quality conventional tyre,a far cry from the square profile tyres of the day,i think they really suit these bikes,err,im getting older but can still push this old frame(the bikes) through known routes and leave big and small twins and novice riders on late jap stuff behind without taxing my reflexes,i run the standard skinny rear,they steer better that way,ive dropped the forks up to the handlebars,they turn a little quicker that way,i like to run a bit high air pressure at 36psi front and rear,20/60 motor oil in the forks,it all depends on your flavour.,all in all youll find we do more of say a left turn or a right turn in the life of the tyre,,our trucks at work are the same,,to get true wear,a proper rotation of the steer tyres should be to dismount the tyre and reverse it on the wheel,then mount it on the opposite side!that maintains the frictional conditions its been used to.we dont bother with that stuff though.

i like the bt45's as well , they are a good compromise between grip and wear [ sportsmax's grip and wear a bit more ] .
a cheap tyre that causes you to crash is suddenly the dearest tyre you have ever bought , best to put up with a little wear even if it is uneven . try reducing both the compression and rebound damping slightly this will give the tyre an easier life , but as you said it is all a matter of trial and error
