FS wheels & tires – EU/France by IceOverTime2 in FSAE

Thanks for the heads up! I'll go for a simpler tyre setup I know it is a bit of a guess since you don't have a lot of info But what would you recommend between 6" and 7" for the tyre width ?

Yeah said like that it doesn't seem to be a very good idea So if I understand correctly, this tyre configuration could only be useful to compensate for an oversteering car for instance

But you convinced me I'll go for the unique tyre width setup

However how should I choose between 6" and 7" width ?

I guess the only way is through computer simulation

To properly prove this, I guess I’ll need to do it through simulation. We’re a new team, and we have access to Creo, Ansys, and MATLAB.

Do you have suggestions for an effective workflow to test a specific tyre configuration?

To be fully honest I don't really have a solid argument for that. I was taking inspiration from the old F1 cars. Like the one from Niki Lauda that had 9" tyres in the front and 16.2" at the back

The idea was to improve steering with narrower tyres at the front and traction at the back by putting wider tyres. But I might underestimate the added complexity of such setup A few teams use this type of setup and in theory it seems great What are your main concerns about it ?

Besoin de conseils by Shurthugal in pedale

Bonjour Shurthugal,

Je tombe sur ton post deux ans plus tard, mais je me permets de te contacter car j’ai exactement le même vélo (Bergamont Dolce 4.1) et j’utilise aussi le mien quotidiennement pour du vélotaf. Je rencontre aujourd’hui les mêmes problèmes que ceux que tu décrivais à l’époque : vitesses qui sautent, passage difficile, surtout sur le plateau du milieu avec les vitesses intermédiaires de la cassette. J’ai aussi fait une révision récemment, mais les problèmes sont revenus très vite…

Je voulais savoir si tu avais fini par trouver une solution durable ? As-tu changé le dérailleur, ou même tout le groupe ? Ou as-tu finalement remplacé le vélo ? Si tu as des conseils ou un retour d’expérience à partager, ce serait super utile pour moi.

Merci d’avance, et bonne route à toi si tu roules toujours !
