Mount it easily yourself, in a minute or so (or get your local workshop to help out, if you don’t feel like getting down on your knees yourself). The point is - no particular tools or skills are needed, anyone can mount it.
Rimgard stays mounted and locked on your wheels all year round. You don’t need to worry about them until the wheels need to come off. When they do, make sure that you bring your Rimgard key (keep one copy on your key chain) and it’ll be a breeze.
