Campaign for clean tyres

[McDuck]

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.

Cheers.

Any residue would have been long gone by then, it was somthing on the road

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

Nah, unless the road is 'banked' (cambered) the load will be the same - gravity only has so much 'pull' regardless of speed.

Speed on the other hand can cause lateral 'pull' that can overcome gravitys 'pull' downwards.

I think....maybe...

No, it was mainly straight road until then. It would have been the new lean angle.

New lean angle = smooth (not scuffed or scrubbed) rubber.
If you combine that with some oil or diesel on the road then you can find things can be incredibly slippery.

yesterday i had 2 new battlax bt45s put on, and i havent felt any slipperyness at all with them, i feel way more planted to the road. and i even road home just after it had rained :S but yea i have now done 223kms on them and i havent had any problems. maybe its different tyre manufacturers that have problems, not just a universal problem with tyres.


oh and the guys at cycletreads said sanding the tyre doesnt make a difference and a solvent type substance will only damage the tyre. apparently theres stuff in the top layer of the tyre whick needs to be heated through and disperesed onto the road. thats probably the dangerous stuff

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 :

"You twat I told you to be careful !"

and given that we don't drive cars (which you can't fall off of when new tires have been fitted)

Why aren't we campaigning for them to do something about it instead of just sitting there smirking, taking side-bets on who will fall off and saying I told you so when it happens ??????

Its a feeble excuse if you fall off on new tyres...the coating protects the tyres and need wearing off...and it ain't that slippery. takes about 5 or 6 kms on the road gradually leaning a lil further over as you go.
or a lap or two on a race track....no biggie
