Powakaddy Winter Wheels

Hello all,
First post here… I have an issue locking the winter wheels on to my CT6. They push on ok but then the catch doesn’t lock and they easily pull of. Anyone else had this issue? I was thinking about replacing the yellow catches but the ones I have don’t look worn compared the the ones online.

I’ll be interested in how you get on, as i’m thinking buying some winter wheels for my CT6.
I might now wait as i don’t want to spend £80 and then they don’t fit properly
