Video on the impact tyre/wheel sizes 17/18/19. A few folk have posted comments relating to the noise generated by the Michelins, it will be interesting to see what alternatives folk opt for as tyres wear out 🤔


 
Thanks for the video. I suppose my tyres will last at least 30000km, so the decission is delayed two years (with new developed tyres around)...

Off topic: Are you sure you got a GR sixtysix? ;)

Bye for now Fred

Will have to wait until 01.03.23 to find out Fred 👍
 
When I get through my rears, I'll be putting on Pilot Sport 5s @ 225 sizing. The 215 makes no sense at all. The stock rim can support a 225.
One thing to note, you do have to declare this to insurance as it's technically a modification, so expect a £20 admin fee.
 
Little OT but relates to the topic (Higher % is faster).
Good test of different wheel and rim widths on lap time

I will probably do the same. I reckon the rear tires won’t last much 😂
Also, from what I have seen 225 are much cheaper than 215
