Campaign for clean tyres

[McDuck]

I dont. A sign on the door should be ebough. IMHO you should not ride hard after any work has been done on a bike...

[piston broke]

ah fuckem mate, roll the bike into their shop, dump the cluth and do a MASSIVE friggin burnout in their shop, leaving the oily residue on their shop floor, should stop the bastards smirkin eh? . . . . . . . . lol

now thats the way to scrub them in,
but you've gotta do a donut each side as well,to wear all the tread

[jonbuoy]

Ummmm whatever... While hardly empirical I've read heaps of "I binned 500m from my driveway" threads on KB compared to zero "I binned 500m from the tyre shop" threads.


That said I'd support having a standard printout that shops could give to people explaining how to safely scrub in new tyres but I don't want people messing with solvents/sandpaper/etc on my behalf.

Maybe the manufacturer should be thinking about doing it?

I would rather save the 10 dollers per tyre thanks

Given that the accepted doctrine of dealers and tire vendors is that a warning to take care when riding on new tires absolves them of any liability :

So what about when you get new suspension fitted - they warn you to ride carefully until you get use to it
Buy a bigger bike - tell you the same thing
New brakes fitted - take it easy for a bit until they 'bed in'

It's just good advise!!!!! what's the issue????

If you are talking about the slippery oil residue on new tyres, then yes they should do something about it.

I think some one should write to a tyre manufacturer (or tire manufacturer) and get some clarification before launching a campaign - I would strongly suggest this idea tyres have a residue from the release agent, is an urban myth.
And I wonder if the number of people who have actually fallen off due to new tyres is actually very many at all?? who knows? who keeps these figures?
You take it easy because the tyre has smooth sealed surface from the mold - the external temperature in manufacturing the tyre kind of glazes the tyre surface, once they have warmed up and the surface scuffed (scrubbed) in a bit there's no issues
I have not found this challenging, scary or a problem
I think a lot of it is in the mind

Or blaming somthing for a crash

Except when I fall off - I reserve the right to blame the first thing that comes into my mind

Just off to the shop to pick up my rim with a new Metzeler Z6 front fitted.
I bought a new rear Z6 last month and it felt good from the get-go.
I have already been warned to "take it easy" when I dropped the rim off.

I do not agree that anyone should be able to sell you tyres which are potentially lethal in their new condition. I think that the manufacturer has the responsibility to ensure our safety.
Someone has already stated on this thread that car tyres do not suffer from this same problem. Put a new set on a car, it's fantastic straight away !

[scumdog]

Ive had suggested to me that I spray some Brakleen onto a rag, then wipe the rag over the tyre to remove the slippery stuff. Didnt try it myself I just went very easy in the first session of my trackday to bed in the new tyre and get it up to temp. it must have worked as I didnt fall off.

Always give the tread of new tyres a wipe-down with a rag soaked in paint-thinners.

Just to be sure.

Really?? I'd rather pay it - horses for courses I guess.

It doesn't look like anything can be done about it anyway - info on it here, seems like its written in Ingrish but but usefull none the less:

Running-in tyres

It is important to understand that running a tyres in doesn't just mean a scrubbing in the tyres surface. Scrubbing under a tide is surface is the only one of the reasons for running a tie is in.

A tyre needs to be seated on the wheel. This is not fully achieved when fitting a tyre and it needs to be ridden on with caution to complete the process.

In order to achieve optimum performance, there are various components after tyre (belts, tread strip, etc) need to correctly bed in to one another. If not correctly run in a tyre may not give their until Possible performance a.

When new, a tyre has a in very smooth the surface and in order to obtain optimum grip, there smooth surface needs to be scrubbed in. At first the bike should be ridden as upright as possible. Gradually, that angle of lean can be increased, always insuring it that a portion of scrub in tread remains in contact with the road until full lean angles are achieved. During careless of time the bike should there be ridden cautiously. Hard for sudden acceleration and braking it should be avoided because optimum traction levels will not be achieved until their running in process is completed.

Not all manufacturers use releasing agents during the manufacturing process, bought for those that do, the scrubbing in process will need to take into account their fluid residue as well as the smooth surface. These agents can also contain anti-ageing preservatives and this is why there manufacturers do not remove them before shipping to their customers.

Wet weather can increase of their required running-in distance by as much as three times.

Rubbing a new tyres surface with an abrasive material in order to scrub the surface in, has little effect. Even very abrasive materials will not scrub that tyres surface sufficiently for the bike to be ridden hard right away. And besides, the tyre still needs to be seated on the wheel and then various components still need to be bedded in against one another. Put simply, there is in no short court to running at Tyre in correctly.

Following the fitting procedure, the tyre should be wiped with a dry cloth in order to ensure no residue off tyre fitting lubricants remains.

100 miles is considered a safe distance to run tyres in. When this distance has been covered, the tyre should be checked to insure all correct seating and inflation.

If a customer crashes on a new tyre, and assuming it has now fitting paste residue, it is a very unlikely that the tyre be at fault. Thankfully, the very few people crash on new tyres, but in virtually every case the error can be put down to lack of care by the Rider. Over the years it has been found that when a crash occurs it is more often than not after a new rear tyre has been fitted, usually within the first mile, invariably at low speed when the rider is making one of the three following Manoeuvres

* Pulling out onto the road went leaving the fitting Bay
* Turning right when pulling out of a t-Junction
* On a low speed roundabout

In these cases, riders have been leaning their bikes over far more than they realised and combined with an opening the throttle, their new smooth tyre with its reduced traction levels, can spin off with obvious results. These crashes usually happen at low speeds because forces acting upon the tyre are lower than at higher speeds and therefore it is far easier for a tyre to lose traction.

Eh????

[Big Dave]

I love new tyres - you can slide around like Haga real easy.

[jonbuoy]

Eh????

I guess they mean loading on the tyres - higher loading at higher speeds? Don't shoot the messenger

Picked up the wheel and is now fitted to Beemer.

Jonbuoy's post makes a lot of sense actually, as I have had some experience with the various scenarios.

Firstly, there is the 'surface' problem where there is a slippery residue present on the tyre. This can be various unidentified substances.

I have had problems with this issue on of all things...A LOW SPEED ROUNDABOUT...!!
After a "new bike for the road" holiday of 25 years, I took took delivery of my SM. On the ride home, after 20 km, I came to a 30kmh roundabout. I rode round very carefully but both tyres still let go simultaneously and it was only the instinctual reflex of slamming my foot down onto the road that kept us upright.
This I would put down to tyre residue and I feel something should have been done about that at the shop, before I rode it away. This residue I feel is the problem most people would have an issue with.

The subject of then "running a tyre in" also has validity.
I bought a 21" Kenda front for the 400 last year. On the attached label it clearly stated that the tyre needed to be run for at least 100 miles before it performed normally. I rode to work and I was so shocked at its dangerous handling characteristics, that I was ready to take it back to the shop and tell them where to shove it !
But I decided to abide by the instructions and gave it 200kms to come right.
It did come right and is now a great tyre !

So yeah. I'll now go and wipe the Z6 down and also pat some dust from the ground on it to soak up any slipperyness. I will also be riding in such a manner to get the "feel'" of the new hoop first before forgetting about it.

Cheers.
