Tyre wear problem

[KS34]

Looks like cold tearing to me, have you got tyre warmers? did they get up to temp?

[Robert Taylor]

So bloody cold then? A contributing factor in conjunction with the incorrect suspension would have to be that the tyre wasn't anywhere near it's operating temperature.

That is 100% correct. Please though dont start an argument about tyre warmers!

Not all is caused by "cold" tyres...............linky

Don't recall it was that cold but the track surface probably was.

Personally I think they might be great if you can afford to put a new one on after every race. But then who wants to pay $300 a race for a 0.2 sec improvement in laptimes. Possibly coming out of the hairpin was the only place the SV had enough power to deal to the tyre.

Would be nice to try an SC1.5

Great link but all those wear marks are running with the tyre mine are more across the tyre.

Thanks Tony actually the pictures of your tyres got me thinking on this.

A question for the 600 guys. Does a 190 wear any better then a 180 or is the difference unnoticable?

Your choice is to either take steps to fix the sources of the problem or to band aid it. The first option will ultimately make you faster and I believe that is a good part of the mentality of road racing.

Option 1 Average tyres and great suspension equals average lap times

Option 2 Great tyres and average suspension equals average lap times

Option 3 Great tyres and great suspension equals great lap times

Most people I know prefer option 3.

Enough said

From what I've seen (not a lot), running a 190/55 is more about increasing the side grip available, and helping turn the bike quicker due to the tyre being taller than a 180/55. Moreso when fitted to a 5.5 inch rim instead of the 6 inch rims on the 1000s

Yep a 190/55 is going to be alot taller than a 160/60 when fitted to a 4.5 inch rim.

You'd need to ask Karl Morgan about that

I'm just wondering how close it will be to the chain or will I have to grind one side off a bit.

I was wondering what other racers have done when their tyres start wearing like the one on in this picture. Once this happens your tyre just gets worse and worse.

What causes it? What is the technical term for this kind of wear?

At the time this happend it was at Manfield on test days and my bike wasn't the only one it was happening to.

I will post my solution to the problem that I have stuck to for the rest of the time I was racing but recent ideas have me thinking there may be a better solution.

Any input greatly appreciated.

This was on my old SV650 with Std frontend with emulators and from memory a way to soft GSXR rear shock. The tyre was a fresh new Pirelli Diablo Superbike slick SC1. The track was Manfeild before any resealing work had been done.

have you worked out this is because of the bikes shit suspension yet??? or do you believe you could fix it with pressures and compound changes??

Bridgestones work well on SV's - anyone else on here tried 'em ?

I haven't found a tyre thats bad on an SV just different handling characteristics, wear, and performance.

The SV being a very low powered commuter doesn't eat tyres. Just get the right tyre for the track conditions ie temp etc, how long you want them to last, and weather conditions.

SV you can use very soft fronts and they wear well but be careful putting soft stuff on the back in cold winter conditions when the tracks suface is cold or you will get wear like pictured in the first post (Cold shearing)

Approriate this thread has been dredged (its a year old) as its getting near the Vic Clubs winter series. If I was running Pirrelli slicks on my SV I'd be useing an SC0 or SC1 front and an SC2 rear on any cold day. And tyrewarmers of course.

I run these at trackdays and they last for ages and my bikes got a standard rear shock in it.

changed your tune again??

If you are refering to Tyrewarmers. If the rules allow for something that can help you then of course you will use it.

I think for example ProTwins would have been a far more interesting class and would of added diversity from the other classes if it was a control street tyre that could handle wet and dry conditions and also had no tyrewarmers (just like streetstock). Oh and also standard shocks with only spring and oil changes. But dogbones allowed to be shortened to improve steering.

I've been on this same tune like a broken record for some time now just ask anyone who races that I talk to often.
