: Tire wear more on front vs rear?

I have been riding for years and almost always my rear tire was worn to the edges before the front. I went riding last weekend and friend pointed out, "dude you have no bitch strips on your front tire." but i still got 1/4 inch strips on the rear. I could care less about having chicken strips, i ride how i ride, but out of curiosity and the interest of always improving my techniques and be a better rider, how did my front tire wear more than my rear?

am i coming into corners too hard?
is it cause i went to a 190/55 this year?
suspension (i did gain 10lbs between last year and this year)?
:dunno:confused:

The majority of the front tire wear issues I've come across are geometry related. Have you pulled the forks through the triple trees at all, or done anything (aside from the 190/55) to raise the rear?

Also, have you had the basic suspesion setup done (sag, and basic damping adjustments)?

majority of the bike suspension is stock because after checking sag etc stock was fine (i was 5'9" 160lbs when i bought the bike, now i am 170lbs). I havent adjusted the forks or anything either.

Yes rears wear faster. You're right if you change tire size or even tire manufactures you need to change suspension settings, you may even have geometry problems that stock suspension can't handle. (example) going to a taller tire 195-75-17 I had to buy a graves top rear shock mount to get adjustability on my ride height correct. First I would check you're suspension sag and see if you are correct there. You may be plowing the corners with you're front instead of really turning through them. Suspension Geometry problems usually make the bike harder to handle, stability is sacrificed. If you like your bikes stability. . Go to a trackday and get advice on you're riding techniques. These 2 should help you, good luck

If anyone has any explanation as to how this works I'd be very interested as well. I have the oppisite problem though, no strips on the back and maybe 1/2" or so in the front.

Sag is correct then how is you riding style hard into corners alot of front brake maybe even some trailbraking through the apex, or mostly on off the throttle smooth lean in and exit. or somewhere in between? You're front may be to soft for you're riding style.

Datsun 280 Thats normal- Hellion is concerned because he is getting more wear and lean angle on the front. it is good to read you're tires it tells you how you're suspension is working against the pavement, As lean angles increase with speed a heavy or soft front is not good for wear or speed. Like everything on a sportbike nearing the ragged edge suspension is everything. Rears wear out faster because of the loads stressed by throttle control or lack of. fronts wear out faster because loads from contact with the pavement, turning. Looking for nice even wear on both tires. Setting sag gets you're suspension in the ballpark, you need to then refine it to you're riding style.

i've never seen zero b!tch strips on the front w/ some on the rear - typically when you get your rear down to zero, the front still has 1/4" or so.

Ja - maybe have a pro/experienced type person help you adjust your suspension

I have the same issue on my bike, I have used the entire front tire, no chicken strips what so ever. On the rear still have about 1/4" to go, the bike is new for me but the guy before was about the same size so I figured suspension didn't have too much to do with it... any advice?

"the guy before was about the same size so I figured suspension didn't have too much to do with it"

That logic would only apply if the guy before you rode exactly like you and he had it set properly. Looks like you are in the same situation as the OP.

Lol.. brake harder and deeper and you'll scrub them off. And just because you have no chicken strips that doesn't necessarily mean you have reached max lean angle. At correct pressures the rear will deform and flex. :sneaky


Sounds weird OP, hopefully you sought it out before you low side :scared

Have you checked pressures lately??

agreeing with roo about posting pictures and with dan about a geometry issue. the only time i get rid of my front strips completely is when i know i'm pushing the front a lot harder into corners than my normal smooth transition through the entry, apex, and exit. usually this only happens on "oh shit" corners and if i have a few of them on a solid ride.

You have a front tire that's about 1/2 as wide as the rear but has about the same aspect ratio(about the same height). Gonna be a lot harder to get to the edge of the front. Completely normal.

I'm also closer to the edge of my front tire than the rear. It's completely opposite than any other bike that I've had and my confidence is just not the same since I've felt the front slip a few times. I need to find the solution.

Well, I think I have my problem figured out. Turns out the previous owner installed a 120/60 front tire and a 190/50 rear tire. At this time, I'm going to replace the front with the proper 120/70 and see how things go.

Sue me for highjacking the thread but since we're on the topic of front tire wear, what causes these damn flat spots on these Michelins? I just finished of my 2nd set of Pilot Powers and both fronts have done it. I'm confident it's in the suspension settings but how do I tune it out? I've got a mad vibration about mid-lean at relatively slow speed because of it and it's a PITA.

hellion, what is your tire profile in the front, and what presures do you use?
the only way I am seeing that happening is with really funky profile in the front and/or really weird and dangerous presures like high in the back and really low in the front.
if you trailbrake like a motoGP hero, in fact your chicken strips in the front will go , but if you were anywere near that level, no way in hell you could have chicken strips on the back!
I am in for pics too!
