WTF? (tyres)

[Akzle]

any ideas?
front tyre. rear shows no bias in wear. i'm pretty sure there's an even number of left and right hand corners in my travels.

we're talking zero tread on bike right, maximum (expected wear) tread on left side....

shat manufacture? bearing going? turns out i'm a dick after all? ...something else?!?!

[steve_t]

Make and model of tyre?

[LankyBastard]

We ride on the left. Therefore for right hand bends you have to travel further than left hand bends. So more wear on the right side of your tyre. Seems funny but happens to plenty of us. Reverse it if you lived in the US/Europe and ride on the right :msn-wink:

Or when you're on straightish sections of road the camber of said road causes the right side of the tyre to contact the road more than the left??

bridgeys, bt45. probably not even 6 months on em...

this is really excessive though, even for riding (mostly) on the left...?!

[Jantar]

...

You get 6 months out of a tyre? :gob:

[Katman]

Turn the tyre around.

There's probably another 3000 kms left in it.

no i reckn it's been one of them parabolic curves. liek, it was fine last month. now it's fucked kind of parabola.

Yep, those pics look about normal, even for a green writer...but hey, six months out a set of tyres? I wish I could achieve that...:facepalm:

[Madness]

You're a dick.




That is all.

[Akzle]

by my calculations (which are perfect, obviously) that's about 6300kms. tyres should go more than that, shirley?

Maybe. If you're lucky or buy cheap nylon tyres.

BT45s are pretty cheap, think yourself lucky you aren't replacing Pirelli Angels or Michelin PR3s that regularly.

[steve_t]

Got about 4-5000km from a set of BT-016 if I was lucky. We'll see how these Pirellis go

[rickstv]

If its a directional tyre, I wouldn't recommend you turning it over.

Rick.

Completely depends on the tyre.

Shortest life I've had was a rear at 1500km on a 1L sportsbike. Longest is 24,000km for a front on a Hornet 900. Your mileage will likely be somewhere within that.

[malcy25]

Do you like Rights over lefts (I used to).


Frame bent.....

[James Deuce]

Left over right and under, right over left and under.

This dear folks, is a reef knot.

really.? delaminating the front isn't a bundle of laughs... who'd'a thunk...

well. it is. at about 6200.
i was hoping for somewhere nearer the 10k-24k mark. which brings me to my next question.
what tyre give me 24k?


Do you like Rights over lefts (I used to).


Frame bent.....

i have no preference. that i've noticed. (as said, the rear has no bias) i'd prefer to drop my bike on the right, cos that's the magneto, the oil whooserwhatsit that keeps it where it should be is on the left...


Left over right and under, right over left and under.

what about the bunny, which jumps out the hole, runs around the tree, gets chased by the dog, shot by the farmer and cooked for... ahh fuckit.

((but can you tie a monkey's fist?))

[Corse1]

Its naturaly going to wear more on the right than left due to road camber but that does look excessive. I had set of tyres that the front looked close to that at the end of its life just a little less tread on the left than yours. next set of tyres didnt do it that bad. Do you get your lunchtime kicks by going round and round roundabouts!!

[caspernz]

what tyre give me 24k



Try a car tyre :wacko:

[Kickaha]

BT45 are a bit more sport orientated than some of the cross ply tyre range if you want better life try something like a Pirelli Route 66, I took mine off the XJ550 at 10,000km and they still had plenty left

[Madness]

shat manufacture? bearing going? turns out i'm a dick after all? ...something else?!?!

You did ask the question, Cunt.

[caspernz]

Here in the society we call Earth, real mileage is achieved by buying real tyres, quite simple innit? :bash:

Well seeing as nobody else is goin to ask i will.

Go find a hardened IRC that's been in the sun for the last 10 years....

To be honest I'm suprised you've gotten the k's you have out of it if you have them on the 750, i Used to go through them in about that on my 87' 250 Ninja. The BT-45's are an awesome tyre on small bikes but are pretty soft and with so much area of tread n the fronts they tend to move around a lot and wear quickly, especially if you trail your brakes constantly into corners...

Pilot Road 2ct in the warmer months of the year or PR3 autumn winter ,

Have your forks moved in the clamps ?

Did you check what sort of bike he was riding? I'm pretty sure that neither of those tyres come in the sizes he needs.

[wysper]

((but can you tie a monkey's fist?))[/COLOR]

I actually find those fiendishly difficult to tie.
However I still try.

[Drew]

No one has asked what pressure the tyres are being run at?

6200k's is pretty bloody good in my book.

89 GSX750 ? Michy site says 150/70 for rear and 110/70 for front availiable (if a 70 is ok for a front)
:scratch:

[James Deuce]

When I had a teapot, the only people selling tyres in NZ for them were Bridgestone and Avon. It might say they're available, but I guess checking with Cycletreads is the best bet. I did put a 110/70 on the Teapot once, and it turned steering into a wrestling match of indeterminate results. There's not much in the way of actual "suspension" on a Teapot so tyres tend to get a hard time.

Looking on Cycletreads shows they don't have a Michelin Radial in a 11/70x17 in stock, so I dunno.

I put Bridgestone BT-003Rs on the RVF and they're brilliant (120/60F, 150/60R) but they were pretty much all that was available at that point in time, so it was luck that saved the day, not planning or desire.

[Akzle]

100/90-16 F (H rated)
120/90-18 R (V rated... ^_- )

stock rear is 110, thez smeg all clearance in the swingarm to go wider, 120 provided a better profile when pinched onto teh narrow rim....

[Akzle]

Cycletreads website says my options are the BT45 (have) the Bridgey G "exedra"s or some lovely looking kendas.... which only look slightly better than the kendas on my MTB....

[James Deuce]

Ahh, not a teapot. The olden style 750. So yes, definitely not radials.

[Richard Mc F]

Used the BT45 on a ducati s2 and an fj1200, fairly typical mileage was in the 4000km ( FJ front if rode like a twat) to 5000/6000km on the ducati, very sensitive to pressure.

I ran the fj at 36/42 and the ducati at 34/36 psi

Mismatched tyres, and a wider tyre on the rear. I bet that thing wallows like a whale through the corners compared to the having the correct tyres fitted.

[Drew]

Mismatched tyres, and a wider tyre on the rear. I bet that thing wallows like a whale through the corners compared to the having the correct tyres fitted.Mismatched tyres are absolutely fine ya squid!

The wider tyre on the rear might be fine too, since it's built 30 years after the bike and probably quite a lot better than the factory hoops. Pretty sure I ran 120/80 on "Bobby Sue", my old GSX750ES

120/80 would go rounder than 120/90, assuming rim width is same. -_^

there innt no wallowing that i've noticed.... and since it are der rear tyre that has an extra 10mm... well it innt fuckall really, is it. i didn't want a flat (shape) tyre on the back...
thenn, i never ridden it with a 110 on the back so i can't compare it to stock...

i think it had a (fucked) sport demon on teh front when i got it... so they must come in size... and i think the 2cts did aswell, but the internet is not being helful.

If you're talking about the Michelin 2CTs, you're imagining things.

[mouldy]

Don,t put Bt45s on the front of anything bigger then a 400 unless its a posty race bike ,then you can

Really?, seem to work very well on my MHR and the 750 Katana I had and everything else I've put them on

[sinfull]

Sooooo ?

Wheel alignment or what ?

[Akzle]

bored huh? Reviving old threads...
Dunno. 2hundy sommat worth of lazertec.
Bike is sick. Batt comes off charger today and hopefully it goes vroom.

[sinfull]

bored huh? Reviving old threads...
Wasn't me, they dug it up yesterday
But that excessive wear would make me wonder if the alignment is out


Dunno. 2hundy sommat worth of lazertec.

Like my lazertecs, use em on the HD fronts and even being a soft compound they do 2 rears to one front, roughly 15,000 k

Go buy yaself 5m strechy cord, prop the bike level, tape the middle of cord to lower part of rear tyre so it dont drop (watch it don't slip into tread groove on the very edge of the rear, if the grove goes to the very edge that is) and set up a pin board in front of the front tyre, move and pin the cord so the cord is just touching the foward edge of the rear on both sides and measure the difference to the front tyre !

Or two alloy straight edges a far easier (but expensive)

Then double check the axle marks are correct, before ya wear a hundred worth of that new tyre out

asides from harleys being really gay, my rear has worn evenly, the BTs are reputed for being soft but i still wouldn't reckon it should chew a front out in ~6k but apparently it happens, particularly being a big bike.

i have plenty of string lines, and enough straight edges. i will check les alignment. if the fucker runs. (battery in <1hr)

axle marks you reckon... on the front you reckon.?

[James Deuce]

The axle marks on the swingarm. If the rear is out of alignment it causes issues front and rear. Usually, the axle marks are an approximation, rather than being completely accurate. It's a conspiracy by the bike manufacturers and tyre manufacturers to make us buy more tyres.

mmm. i went/go by how much of teh bolt is threaded into teh hole. and be it even on both sides. adjusted the chain not so long ago (a'fore it fucked out...) rather than the marks on les swingarm.

[Maha]

I am well overdue for some new tyres...the current 021's from new, are now 14,000+ kms old...:rolleyes:
The front especially is in dire need of replacing, next weekend at the earliest, possibly the following, will get both front and rear new'd.
Right hand side is cupped.......more so than the right.

[Mom]

Well, for what its worth, I would suspect under inflation the cause of an uneven wear in the short space of time that the OP's tyre wore out.

Yes, yes uneven camber, cheaper tyre, but I am picking lack of air.

Be interesting to see what Maha's tyre has in it. This damage appeared after our big ride to NP a couple of weeks ago, pressures were fine when we left.

[Maha]

Part of my pre trip bike check is tyre pressure...both were fine (36F and 42R Cold)
I didn't check the tyre pressure yesterday before a 300 km ride. I did however, notice the wear, so after 1100kms, it had lost 10psi.

I wouldn't think where the bolt goes is any more accurately positioned than the marks for the adjusters. The only way to really know that the alignment is correct, is the straight edge method. Or string, but that's more fiddly and a bit of a PITA. Sounds like you're familiar with checking the alignment anyway.

Once I've done mine, I mark the bolts and just do the same amount of turns/flats on each as necessary.

I would have thought if alignment was the cause of that wear, it'd have to be so far out the handling would be bad, and a quite different feel left to right would be quite prominent.

Good luck anyway.
