Intre T1R si EagleF1Asym2 eu le-as alege pe ultimele. T1R am avut si am mai spus ca sunt excelente pe ploaie, dar cam tari pe viraje.

poate fi un incident singular, nu am mai citit astfel de incidente. e important anul fabricatiei cat si conditiile de depozitare. pot sa-ti arat cauciucurile de pe del sol, care nu au prea mare uzura, insa sunt pline de fisuri (cauciuc imbatranit).
nu poti trage o concluzie dupa un singur eveniment.

Da ma, si eu am ramas masca, uite poza mai jos. Liviu, din pacate nu e singular, am mai intrebat si mi-au mai zis 3 oameni ca au prieteni care au patit, asa ca...

@Maruta: mersi frumos man, exact asta cautam oameni care au mai testat variantele si pot da un feedback despre ele, deci momentan inclin balanta catre Goodyear.

eu zic ca aia e urma de taietura, a prins ceva in derapaj si a spintecat guma. aia nu e fisura.

Ma Toma necredinciosu, de ce nu vrei sa crezi ca e un defect la ele si au patit mai multi oameni ...treaba ta, ia-le daca vrei si nu ma crezi .

pentru ca asa mi se pare mie ca arata. fisurile in cauciuc nu pot arata asa, pot fi transversale, la zona de imbinare, altfel, un cauciuc poate sa arate ca pielea de elefant. asa se crapa cauciucul. ce e acolo e ca si cum ar fi fost un şpan pe o iesire in decor, sa ma rog, intr-un viraj in care masina aluneca inspre lateral.
daca ar fi sa ma hazardez mai mult, aş zice ca taietura merge dinspre interior spere exterior (viraj de mana dreapta). ar fi interesant daca ar putea sa-l intrebe cineva daca a avut un astfel de incident.

Nu a avut, am fost cu el, iar ceilalti 3 (dintre care unul chiar in CJ ) nici nu au fost pe track, dar tot asa au patit.

Liviu Detectivul lui Peste

Tind insa sa ii dau dreptate, trebuia sa crape macar pe aceeasi linie

aia i taietura man. Mai multe poze?

Nu sunt mai multe poze, e vorba de chuckie cu meaganuRS galben.

deci eu imi pun averea la bataie ca e taietura.

pai daca au fost si pe strada, cu atat mai multe şanse.
eu am ceva de genu pe guma de la moto. e mai scurta, logic dar arata lefel.

urmele clare de taietura se observa la inceput (interior), are sectiune oblica cu unghi de incidenta conform sensului de rulare. de ce zic eu ca e pe derapaj, pentru ca urmele de sfartecare vin dinspre interior spre exterior. cine a incercat sa taie ceva elastic cu un varf nu foarte arcutit, recunoaste aspectul asta.
am subliniat cu roşu urmele de care ziceam

Adi, eu mi-am montat Vinerea trecuta Eagle F1 Asym 2. Cu montaj cu tot m-a dus la 125 EUR bucata. Sunt mai silentioase decat Michelin-urile vechi. Am schimbat si placutele pe fata, le-am dat si cu spray de frane sambata si am observat ca franarea este mult mai buna si daca ciupi mai tare frana te da cu botul de bord

Deci +2 ptr goodyear ...multam Bogdane

In legatura cu federalurile, pentru cei care inca au dubii ca aceasta problema chiar exista:

http://www.s2ki.com/s2000/topic/839178-h...e__st__175

"Hi All,
Recently purchased some federal 595 RSR with the plan to run them at superlap in the clubsprint class.
Imagine my horror when after only 15 laps of wakefield at no more than 5 laps at a time one being warm up and another being cool down the tyres appear to have split the casings like retreds.
But the worst thing was the local suppliers reaction....

"After looking at them closely it is clear that they have ‘tread splice overlap feathering’ – this is not uncommon in tyres used for track work and is usually the result of heat build up.
With Federal 595RS-R’s the tread splice overlap is where the top layer of the tread has been joined to the lower layer when the tyre is built, this splice is not where the tread is actually joined to the inner casing of the tyre and when it begins to ‘feather’ like it has in these photos it does not affect the performance of the tyre.

Through our testing and extended use on competition level drift cars, circuit cars and high performance street cars with 595RS-R’s we have never seen a tread separation or delamination caused by the tread splice over lap.

In 2008 Federal tyres sponsored Nathan Weissel in the Drift Australia series and supplied 595RS-R’s for his vehicle. During testing we noticed that the tread splice on his tyres was feathering and after advice from Federal Taiwan decided to re-run the same tyres to see if the splice got any worse.
Nathan wore these and many other 595RS-R’s down to the casing with only one delamination for the entire series and we believe that this was because of the tyre mounting the top of a ripple strip while spinning.

In the extremely unlikely event of one of these tyres delaminating due to this tread splice, it will qualify for a pro-rata warranty replacement."

What bothers me is the offer to replacment on pro-rata basis in the event it fails, without having looked at anything other than these pictures. If the tyre fails at eastern creek @ 250+ the last thing I will care about is a F***ing pro rata replacment.

Considering what I paid for now useless tyres, I'm nothing short of outraged im now out $1400 with no tyres for superlap.

So now my winge is over has this happened to anyone else? if so what did federal do?
Also note i didn't drift or overheat the tyres and the email quoeted is word for word and complete.

Cheers"

man, nu te incapaţana sa lupti impotriva unei probleme pe care nici unul nu stim de unde a aparut.
ce imagini am mai vazut pe net cu asa ceva sunt cu fisuri liniare, pe zna de imbinare a stratului de cauciuc, decii n linie dreapta, ce ai pus tu prima data nu are nici o treaba cu celelalte.
iar cat despre cauciucurile de competitie...:
Many drivers have experienced that their car’s power is able to spin the tires as the vehicle exits the pits and/or unloads the inside drive tire as the vehicle accelerates out of corners. Tire spinning tears at the tread splices and is the most common cause of splices becoming visible or opening. The next greatest possibility of damaging a tread splice is when the stopping power of the brakes briefly slides the tires when slowing from high speeds or the driver locks the brakes and causes the tread splice to slide along the track. With today's manufacturing techniques, the final but least likely possibility is that the tread splice was contaminated during assembly before the tire was cured.

dupa cum se vede, problema e de guma de competitie, nu de marca.
da' cum forumurile actioneaza precum o epidemie avem tendinta sa ne contaminam prea repede. sa nu uitam ca civicul are o problema de tremurat pe care eu...nu o am...

Man eu nu ma impotrivesc la nimic, doar ca nu am vazut la ABSOLUT NICI UN ALT CAUCIUC problema asta si am sharuit cu toata lumea ca sa nu dea banii de pomana pe un lucru prost facut, acuma fiecare face cum vrea pana la urma pentru ca sunt banii lor personali si nu ma bag io.

una peste alta se pare ca RSR-urile au o problema de calitate, ceea ce nu e chiar de mirare la costurile lor

No alea chiar sunt crapaturi, cam nasol de la o guma care costa atatia bani

mah, acum eu nu am experienta in directia asta, insa am citit ca e o problema relativ intalnita la gumele de pista.

La RS2 nu am vazut deloc de exemplu
