Pirelli OEM tyres (diablo rosso corsa)

[xenothius]

so apparently OEM tyres are not built the same as the off the shelf versions and as a result my 4000Km on them has given them flat spots (not visible but you can feel them)

RANT WARNING!

why the hell would you put an inferior product on a brand new bike! a very serious WTF i have no faith in Pirelli's at all now, i was prepared to give them the benefit of the doubt but now i will just go back to michelin's

RANT OVER.

so if anyone wants a 4000Km old set of Pirelli's going cheap let me know (could still be good for a track day or burn outs)

I agree completely. It was many years before I realised that such a cost-cutting rort existed, believing that OEM rubber would be the same as that with the same name available off the shelf. Who is fooling whom?

My original s20r tyres feel like the replacement s20r tyres. I don't ride fast enough to tell the difference wet or dry.

Think of it this way , Said factory buys a container of tyres and the are on the street in three months from manufacture. Mr wholesaler buys and then ships to local seller 5-7 months till they see the streets . Corsa is race so if you are going to work and back you are going to melt them . Do you give them a work out in the weekends to round them off ?

Whenever one buys a budget bike, expect budget OEM rubber. Old news, and it wouldn't dissuade me from buying the same brand of rubber as the OEM brand.

And Mossy...you crack us all up :eek::laugh:

Whats the problem???? 4000km is high mileage on Rosso Corsas.

Its not a case of inferior but more of the OEM tyres usually being built to a lighter construction for all the spec nerds out there that buy based on kerb weight...
The compound should be the same but the carcass might be built a bit lighter and more flex and hence more heat faster wear. If you look at the sidewall the product code will be different too.
I'm with Mossy, the OEM trailwings especially the front felt just as awesome as the replacement trailwing I bought for front, both did about 8000km, tread 2/3rd worn but the compound goes hard with age/heat cycles.

Had rosso corsa's on my tuono from new...cant say i had any complaints with them, managed to get 6k out of them. Definitely more than i manage to get out of the metzlers.

Not to go off-topic, but is this actually true? I remember reading this a while back but I couldn't find any proof online when I was trying to tell a coworker about it. :bleh:

It's been outed some time back by the major US magazines.

OP - flat spot you cannot see but you can feel? If you can feel it you can see it.

All rears flat to a degree regardless of make bike etc. Worst recent case I had was Conti Road Attack 2's - great tyre but I think they have their mix off - the front chewed the sides the rear centre went too early. Shame as they were stick mothers. Oh - same bike, numerous tyres to compare with and same riding (and rider!).

[xenothius]

I did about 10k on my michelins (very light bike) and only used 10% of the tread with no flat spot and the same type of riding, they might just need a good flogging on some twisties, the diablo's still have most of the tread still. am I setting my standards to high for the durability of a multi compound tyre?

I didn't think a street triple was a budget bike

Show us a photo of your tyre?

[mossy1200]

Durability has a tendency to decrease with an increase in traction.
It is what it is.

Personally I like the stick better for less time than the not stick so good but last longer than the bike approach.

Your choice. Tame yourself and ride harder tyres if you like.
Its most likely you ride harder than you used to or you run lower pressures than the tyre was designed for.
We haven't seen said tyres in a photo. Are they blue or grey or silky black after a ride? What pressure are they when cold and when hot?
Are we talking cold shear or beading up. So many factors that are not the manufacturers fault that are more likely user induced unusual wear.

I can see 5 formed flat spots across my rear tyre now that its almost dead.
I have the outside beading with the centre cold shearing.

Disclaimer : All achieved at road legal speeds without sustained loss of traction.:doh:

if thats how they are then thats how they arehttp://i1225.photobucket.com/albums/ee394/xenothius/IMG_3644_zps5224a697.jpg (http://s1225.photobucket.com/user/xenothius/media/IMG_3644_zps5224a697.jpg.html)

Pretty standard even wear for a sports tyre to my eyes. You can see the change from harder centre to sticky sides - that's also normal on dual compound tyres - some people claim they can feel the transition when riding. I can't.


That one has plenty of life left in it - get out and hoon.

[xenothius]

if its normal then i may as well keep them on until they're dead then swap them out for a touring tyre or buy a new bike

and most likely take the bike for a run over to Raglan after work :whistle:

[R650R]

I cant see any flat spots, OMG those are still practically brand new condition, no wear at all.

Seriously dude you don't need to worry till they start looking like this....

BTW the Michelin pilots have the same visible seam on dual compound also, they even mark it with white line now so you know its not defective when you buy.

Flat spot now a lot smaller after a nice run to Raglan and back :shifty:

IKR! 2700kms has rooted them completely however I may have had a bit to do with that

back is 2200 each. Still on original front. Must be a three to one ratio tire. I found rear wheel steering helps keep the front in good condition.
