Just checked mine, they were new on for Worksop and did 1 practice, 4 qualifiers and a final - got plenty of abuse during this ofcause.

No damage to any of my wheels, all seem fine.

They are very lightweight and flexible wheels, I have cut a few pairs narrow ready for Belgium and they are very plyable - don't seem brittle. I wonder if you have just been unlucky.

Saying this, the Minipin tyre does provide plenty of protection to the wheel as they overhang plenty, when we run Minispikes for outdoors the wheel is more exposed.
