My bt002 street tires ended up looking like this

Is it because of my suspension? The left side is really worn out while the right side still looks pretty good. :scratch

Tracking off? Meaning my wheel is misaligned?

There's a simple string test you can do. Center the front wheel and run a string parallel from the front to the rear and take measurements from the string to the side of the front and back of each tire. It's explained in the manual.

If the truck was going unticlockwise and you have done this question then then i will start to beleave that your knowlage about bikes is very little.

Bump this to the new posts section.....now I'm curious to read what other people think is wrong.

The wheel is aligned properly, and the chain is not too short. I guess I should've made it more clear in my original post but I am better at making left turns.

I just thought it was odd that I only got 1500 miles out of a DOT street tire. From what I know suspension has a lot to do with tire wear. My buddies gsxr1000 has the same tires and he said it lasted him a really long time.

Know lets get this right.
most likly the track was going unticlockwise thats why the left site is more worn. thats normal.
i used BTOO2 for the only track day i have done in my life. It made 1350 miles it looked like yours in the end (the right site was more worn clockwise track) and the 1000miles was the trip to go to the track and come back. so hard 1500miles on BT002 its normal

Was yours the BT002 DOT race tire? or DOT street tire?

My two buddies one with a k6 1000 got 5000 miles on his, and another one with a zx10 got 5 trackdays out of the bt002. And those guys both weigh 200lb+.

I'm 155lbs and I'm on a 600. Is there any other reason why I'm eating up the tires like that?

Yes there is. Your more agresive than your friend most probably you are faster too. what ever tire i put in my bike is worn on the sites faster than on the center and thats street riding. your tire looks like there are more than 2000miles of easy highway riding. so there you have it 1500 + 2000=3500 thats not bad at all.
my bt002 was a DOT medium (type 3 i beleave).
By the way i will never use it again too soft for street riding and the profile is set for big leane angles which you will never use on the road.

A close pic of the tire would help discern suspension issues. How loose is your chain? Can you move it up and down at least an inch? Your suspension will bind up from the chain if not causing the tire to become the shock and wear out quickly. Also what pressures (cold) are you running? Have you checked them hot as well?

Could also be track surface coming into play. The surface at Miller the first year would eat a set of tires in a day. I can kill a set of slicks in 2 days on it now.

My chain is somewhat loose right now, just a tad bit looser than the manufacturer's recommended slack.

And cold tire pressure is 31 front and 30 rear since I ride fairly hard on the canyons.

I'm just baffled by the quick wear since the bt002 I have is the street version. I figured I should get at least 3000 miles. And I heard from some more experienced riders that a good suspension tuner can tell whether the suspension is set correctly by looking at the tire.

My suspension feels fine, but I'm too n00b to be able to even tell if it really is fine or not. So I figured there might be something wrong with my suspension settings (ie. too hard/too soft).

presures are a bit low even for fast road. low presures are wearing done the tyre faster. It doesnot look like a suspension problem but what are your riders sags?

I don't know.... haha my suspension is really half-ass set.

it is impossible to tell your suspension issues from a tyre that worn, and smoothed over by street use.

post up pics of a new tyre after a track day and we might be able to get a better idea.

BTW, you dont make slicks by wearing out the tread Will, but keep at it and maybe you can porn it off on ebay as one:lol

Tasman

Go and set the riders sag first. i am 165lbs and i have soften the rear to get to the recomandations. since you are lighter most probably you will need more.
Find a friend who knows how to do it or do a lot of reading before you start. messing with the suspension can be very dangerus.

I did sorta tinker with the front settings 2 weeks ago. I set it back to the standard setting per users manual and it handled like shit. The front would push and felt unstable.

I set the preload a bit harder and the rebound 1 turn back to hard and it felt good again. But I think I'm going to bring it into a reputable shop to get the sag and settings dialed in especially since I'm getting some grippier tires for my next set.

Is my tire still good to ride on though? The function of tread is to redirect water and I never ride in the wet so would my bald left be fine for dry conditions? I'm waiting to get a set of michelin power races or sportmax gp's right before my next trackday. :cool

ok ok but what am I going to do with the front tire? It's halfworn. .... would people still buy it?

that rear is done. in any conditions.

dont skimp on tyres, by a new set.

the best thing you could do is by a set of second hand wheels somewhere. mount your track tyres on them and swap them out everytime you go to the track.

one other thing, dont even bother trying to set your suspension on tyres that worn its a waste of time.

the feedback you are getting has no relevance to the feedback you will get with a new/ish set on.

when i rode streets at willow....i noticed the i wore out the left side of my tire also because the left turns are a little more harder. that could be the problem. also tire pressure plays a huge role. how harsh was the track? are they the older 002 or the new racing streets?

The track was mostly left turns, and it was a pretty cool day.

I originally meant to buy the bt002 DOT race (type 3 type 4) but I didn't know they also had a street version.... so I didn't specify what I wanted when I ordered the tires.

So I ended up getting the racing streets which are the equivalent to the michelin 2ct's. They still grip really well but I spin them up pretty easily when I'm hard on the gas.

People generaly want the rear tyre not the front.
I always chainge both tyres.
I noticed thou that when people put a new tyre at the back and they leave the half worn at the front in a very short time the frond is gone.

what i do is chainge both tyres before is complietly bolt in the site and their is plenty of thread in the midle. then sell it as a set. Freeway riders want them.

Hmmm good idea....

I just think its kinda wasteful because I have a set of 2ct's with probably 30% tread left laying in the garage. And now my bt002 front has around 50%. Maybe I'll try to sell them dirt cheap like $30 a tire.

How do you get your tyres so smooth if your spinning them up?

Mine have clear tear marks from squirming, I dont commute on the bike so it never gets a chance to smooth out. Once your spinning them up and tearing them I figure you need to do atleast 1000klms of slow suburbia stuff to remotely smooth it out. Thats a lot of coffee!

I never liked the 002's, the front doesnt give a lot of feedback and wear is really shit. Actually one of my mates used a set of race take off's at about 70% life left and killed the rear in one weekends worth of riding (400 klms)

I have been saying for months that the 002's were poor, wear on the track seems to be OK and normal for a DOT but its like as soon as you put them on the street, they wear stupidly quick. If you never ridden on anything else, they are good but when compared to other DOT's they dont stack up.

Clearly you favour lefts then rights, but not only this you clearly accelerate much harder on lefts!

I wouldnt run anything less then 34psi unless you have a solid 20mins of knee dragging twisties.

Try the metzler racetec's, there is a K1 K2 combo on ebay for like $250 US where everyone else on there is selling just the rear for like $199. I have 2500 klms on mine and they are wearing really nice compared to my riding buddies although but I do have suspension mods which also helps.

Well its not like I'm spinning up leaving a strip of rubber down like 1000's do. But on the occasions that I do spin up the tire in the tight sections it does look wrinkly afterwards. Then after a day of riding it smooths back down. And note that this is the bt002 st... not the pros. If I had the pros I don't think I would have the traction problem.

Up close its not really that smooth
