Title: Beta7 - strange tyre masses (on 990)
Post by: HornetMaX on October 27, 2015, 11:28:41 PM
@Piboso:

I was diffing physics files between beta6 and 7 and I noticed that the 990 front hard tyre has a mass of 8.75 in beta 7. Which is weird as quali/soft/wet are all at 12 (and all of them were at 12 in beta6).
Also, the 990 rear hard tyre mass is down to 12 from 15 (all other rear ones are at 15, as they were in beta6).

Not 100% sure they are bugs, but ...

The changes in tyres masses of the other bikes (125, 125cup and 500) look OK.

Front tyre witdh in B7b is raised from 60 to 80 on all Murusama front tyres.
Masses on front tyres are all to 8.75 updated in B7b.

Yeah, the width change makes sense, 60 for both rear and front was a bit strange (not that I noticed, but now that I think about it ...).

For the masses I just trust the boss, except when he's in typo-mode :)

But why only on the Murusama?

QuoteAlso, the 990 rear hard tyre mass is down to 12 from 15 (all other rear ones are at 15, as they were in beta6)
It still is in 7b and did not make sense to me.
On the Varese, 125 all rear and front tyre masses are equal.
Varese 8,75 front and 11,5 rear.
125 is 6 front and 7 rear.

e.g. Real front slick weight is about 5kg and rear 7kg (125/80-17, 195/65-17). PVM Magnesium is about 2,5kg front and 3,3kg rear (5y spoke, 3,5*17, 6*17). Other manufacturers are equal in weight (Marchesini, OZ,...)

I have to say that the rear wheel mass of 15 is definitive too much.

Didn't have time to check yesterday evening.

Guess a beta7c is needed :)
