Update v1.54:

BUG FIXES
Mothership Pro Wheels
The Wheels will remain in every player’s inventory, but the name will change from ‘Mothership Pro’ to ‘Mothership’
These Wheels will maintain a ‘Common’ rarity designation
If you redeemed a Mothership Pro code on your account, you will receive a new white-colored ‘Mothership Pro’ Wheel with ‘Limited’ rarity status
Code holders will also keep the Common ‘Mothership’ Wheels
If you received a code from attending the RLCS Season 5 World Championship, but have not redeemed it yet, the code will now unlock this new white Mothership Pro in your inventory going forward
