Michelin will remove its softest rear compound from the allocation for Sunday\u2019s Japanese Grand Prix following multiple instances of tyres blistering during Saturday\u2019s half-distance sprint race at Motegi.<\/p>\n
But it will not, despite lobbying from some teams, make its emergency hard-construction tyre mandatory for the race.<\/p>\n
It became apparent during the latter stages of the sprint at Motegi that numerous riders were struggling with their rear tyres delaminating, something that was predicted as a possible concern on the newly-resurfaced Motegi asphalt.<\/p>\n
Pecco Bagnaia was forced to retire from the race with one lap to go, while championship leader Jorge Martin was lucky to hold on to a podium place, finishing the race missing pieces of the rear aerodynamics of his Aprilia after they were shattered by his disintegrating rear tyre.<\/p>\n
That delamination, a symptom of low wear and high grip that causes a build-up of excess temperatures, was something that Michelin had predicted might be an issue – with the French firm coming prepared with a third rear option using the special construction designed to cope with the high heat that similar tracks like the Red Bull Ring force onto the tyre.<\/p>\n
\u201cWith the new asphalt we never tested here,\u201d Michelin boss Piero Taramasso exclusively told The Race after the sprint. \u201cWe know Motegi is a demanding track, and that is why we decided to bring a third rear specification.<\/p>\n
\u201cIn the meeting on Thursday, we already spoke with the riders and the teams, and told them to be careful and to check the temperature of the tyres. It [the soft rear] was at the limit, yesterday and this morning, almost for everyone, but we said ‘OK, for 12 laps, we can try it.’<\/p>\n
\u201cAfter the sprint, there were three bikes with quite bad blisters. The blistering is when you generate a lot of heat inside the compound. The construction stays intact, but you get bubbles inside the compound and it opens up and makes holes.\u201d<\/p>\n
It\u2019s believed by The Race\u2019s sources in the paddock that a number of teams subsequently called for Michelin to make the aforementioned hard tyre, brought specifically for this situation, mandatory for Sunday\u2019s race.<\/p>\n
But these teams have not managed to persuade Michelin to take that step – given that, according to Taramasso, a number of rivals had no issues on Saturday.<\/p>\n
\u201cWe know that in the sprints,\u201d he told The Race, \u201cthe riders don\u2019t manage anything, they just go full, so probably the situation tomorrow will be a bit better.<\/p>\n
\u201cWe spoke with Dorna, and the decision for the race is that the rear soft won\u2019t be allowed, and they will have to work with the medium or the hard one. The Michelin suggestion, we really strongly suggest to use the rear hard. That\u2019s why we brought it here, but now it\u2019s up to the teams and the riders to decide.<\/p>\n
\u201cThere are some bikes, like the KTMs, some Hondas, that don\u2019t have the problem. They manage well to not put a lot of energy in the tyres, and we don\u2019t want to penalise them and oblige everyone to go with the hard, even if we suggest it very strongly.\u201d<\/p>\n
That is likely going to leave a number of teams in something of a dilemma for the main race, though, given that Jack Miller – one of only two riders alongside Marco Bezzecchi to use the medium in the sprint – also experienced similar blistering issues.<\/p>\n
\u201cWe had two mediums on track,\u201d Taramasso added, \u201cand Marco was clean but Jack had some blistering, too. The medium is stronger compared to the soft, but if your bike\u2019s setting is not optimum and you have some more spin, then what you have to do is do everything in your power to limit the spin and put less energy into the rear tyre.\u201d<\/p>\n
The decision not to make the hard tyre mandatory will come as welcome relief to some, most notably sprint race winner Marc Marquez, whose factory Ducati has struggled all season to use the heat-resistant rear construction, conceding valuable championship points last time out at Austria to the factory Aprilia duo of Martin and Bezzecchi.<\/p>\n
Given the hard option has been roundly ignored by teams so far in practice this weekend, Sunday’s warm-up has been extended from the customary 10 minutes to 20 at Michelin’s request, “in order to allow all riders to evaluate” the hard tyre.<\/p>\n","protected":false},"excerpt":{"rendered":"Michelin will remove its softest rear compound from the allocation for Sunday\u2019s Japanese Grand Prix following multiple instances…\n","protected":false},"author":2,"featured_media":915162,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[572],"tags":[64,63,806,805,803,804,85],"class_list":["post-915161","post","type-post","status-publish","format-standard","has-post-thumbnail","category-motosport","tag-au","tag-australia","tag-motor","tag-motor-sports","tag-motosport","tag-motosports","tag-sports"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/915161","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=915161"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/915161\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/915162"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=915161"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=915161"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=915161"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
