I had the same question but I have understood that most of the testing has been done in factory. Or they didn't get to test them with hot weather, the last test was on muddy conditions.
The thing is that the team has just 14 test days because Tänak is the only driver. Last year he and Evans had 40 test days in m-sport.
its not that they didnt know that they will have problems with heat,and long stages.Of course they know it.
The problem is the dont know how to fix it.
All the B brands of tyres are very close at low temps (asphalt mud and gravel) with A brand tyres.
The problem is when heat climbs and the stages are long so you have to control the wear.
At hotter rallies the difference will be more.
And Portugal wasn't actually very hot. Also, do I remember correctly that they nominated hard compound for Portugal? So does anybody know if Tanak was on hards when the overheating supposedly happened?
No, he was on softs.
I guess dimviii is right. Tänak said that he doesn't expect to be that fast in Sardinia because of the hotter temperatures.
I red out a bit differently. these are new tyres and he didnt know exactly how they behave. Remember, the tyres didnt wear out, next stage he was fast again. The problem was that they overheated too quickly and started to move too much under the car. So, on the longer stages he needs to be less agressive not to overheat tyres so much and then the performance last until the end of stage. So, it was the first experience in competition mode and now he knows it better. Lets see how reacts in competition conditions in next rally And we do not know much about the harder tyre performance yet.
There is so many variables with tyres, especially new ones you have limited experience with.
It could be that the soft is good short distance and the hard is better on the longer distance. And that stage was followed by shorter stages, so over 3 stages the soft suited more of the stages, so he went with that compromise, knowing he would loose time on the long stage.
It could also be that the soft is good long distance, if it's cold enough. And that hard is only good in heat. And so again, a compromise, too cold for the hard, but not cold enough for the soft. You can't get 2 tyres that will suit every environment.
It could be as simple as car setup to suit the tyre too. The temps and pressures in the softs may come up faster than the hards (quite possible) and over a longer stage they went off the acceptable range, so he had to slow to manage them so they weren't destroyed for later stages where they are better suited.
There is many variables with tyres and not a black and white situation. And you can't always test every scenario beforehand.
Yeah, you guys are right. That's why it's shame that they couldn't get more information about the tyres. But the season is still long .
The stages in Sardinia are mostly under 20kms but the surface and the Heat are much harder.
DMack have entered Tanak for Ypres Rally... interesting !
testing purpose like in 2014 with barum rally
DMACK Tyres
We've entered Ott Tanak and Raigo Molder for Ypres Rally later this month. Hoping to build on our series of fastest stage times on asphalt at Circuit of Ireland after more tyre development.
