oh well - may as well add it here too
Ex-mil LR 110 (registered with side facing exhaust etc etc)

Tyre manufacturer : BFG
Tyre model: MT (tubeless of course)
Tyre size: 255 85 16s (this size spare also fits in the spare wheel space - probably the largest that will fit in that space)
Wheel size of offset: ? ? - standard D1 wheels (as you can see)
The speedo over-read is now quite minimal.
It probably also helps that it has a KLR turbo to help drive the larger diameter tyres
