After reading all the comments, I’ve done the exercise of removing the cover and spare wheel.. It was a piece of piss three minute job in my case…. The hex screws came out with no trouble, ditto the spare. There was enough torque on all the fixing to prevent them working lose and no thread lock present. The cover acts as a stud catcher which would be handy on a dark and stormy night.
My Gren was a mid December build and has the alloy wheel spare. Now they are off, I’ll apply a smidge of silicone grease before putting them back on.
Used all the Ineos tools..
