Tyres scrub in - how long.

Nürburgring course I had to have a new tyre fitted, my German instructor said "Ein links, ein recht und den allez OK"

Alles klar, danke.

Got the oul sandpaper out and spent 20 mins rubbing the tyres. I know it sounds nuts but I went for petrol then, about a 15 mile round trip and by the time I was almost home everything felt fine. Mixture of wet and dry surfaces.
Felt a little bit skittish for the first 3 or 4 miles but improved noticeably as the miles went by.
Had her up to 80mph on one straight stretch before running out of road.:augie
 
I know some Police riders scrub new tyres with a wire-brush and really hot soapy water. :thumb2
 
If you lack confidence in your new tyres why not lend your bike to a mate till your confidence is restored, sorted !



:augie

Lookin forward to your first outing CP. :thumb2
 
Ya dunt give up does ya ;)

Errrr mmmmm aaaah .... yes, actually, it was :blast
Not having a go at you:rolleyes:

I wouldn't fancy Hatzenbach, Adenaer Forst or Bergwerk in the rain with an unscrubed new tyre.:beerjug:

I've fallen off on der Nürburgring, in the wet, on a scrubbed in tyre :eek:

Well rather than start a new thread, I'll just hijack my own. Out washing the bike there a while ago and I noticed something about the front tyre. I bought this tyre from a well known bike shop in Little Isalnd. They also fitted the tyres and charged me for it because apparantly these tyres take a bit longer to fit than normal tubeless types. so after all that they only put the tyre on the wrong way round. Now the thread pattern on TKC80's looks identical whichever way the tyre is on so, should I go back and get them to do the job properly or can I drive as is. My feeling is I can drive as is but I'd like someone else's opinion also.

There's a right way and a wrong way so take it back and make them change it. All to do with how the tyre is constructed. :rob

The tread pattern of a TKC is omni-directional.

I suspect (though I don't know for sure) that the arrow for rotation is there purely because some rule says it has to be there.

I have never carved up a front TKC to see if there's anything different inside it, but I'd be prepared to bet there isn't.

I HAVE run a front TKC 'backwards, quite deliberately, after it got past 60% worn and I wanted to use up some of the 'bite' from the unworn side of the knobbles......It didn't make a jot of difference and felt just like you'd expect a slightly worn (bearing in mind I'd turned it around) tyre to feel.

On other tyres, there is very definitely a 'right way' and a 'wrong way' around to fit them, and you can expect some fairly major differences in handling and wet performance if you get them wrong.

Having said all that, the tyre place should've bloody checked in the first place....it's not exactly rocket science :blast
 
You both make good points. I've heard that lads reverse TKC's for the last 1000 miles or so but also there's a right and wrong way to mount a tyre.

Hmmmmmmm.
 
Take it back and point out it is on the wrong way. They will no doubt swap it around.

I've just been outside and looked at some of my old fronts.

Annakee 2......tread pattern NOT omni directional, there is a pattern between the inner and outer knobbles that looks like a 'V', but oddly, unless I missed it in the dark, there doesn't appear to be a directional arrow :confused: Moulding inside are not directional

MT21 (probably off the 650) omni directional pattern inside and outside, tyre rotation mark present......I've run this one backwards and forwards (or have done some hard work at good speeds going backwards :blast) going from the wear pattern

TKC80......Omni directional inside and outside, again, the one I have out there is worn in both directions after I flipped it around.





No further evidence to present. m'lud, but I would be happy to continue swapping the front TKC I've currently got on my 1150 around to get maximum wear from both edges of the knobbles, I still don't believe that the rotational arrow is anything more than paying lip service to 'the rules', and I'd still bet that there is NO difference in the carcasses internally.

Common sense......that's what it's about, not rules.

Tyres have rotation arrows because of the directions of the plies inside the tyre. Proper flexing occurs in one direction and not in the other. Front tyres undergo most loading under braking. Fitting in the wrong direction can cause the plies to break internally where they overlap under heavy braking.

Tyres fitted the wrong way should be an mot failure.:rob

I'm happy to accept that at face value with a tyre that has tread specifically designed to shed water in a certain direction, but do you have any evidence or reference to show it's true of a tyre like a TKC80 where the tread pattern is identical no matter which way around it is fitted, or is that just opinion?
