Thanks Mark,
The load rating of the Geolander is the same as your current Dynamo? (Chinese?) tyres - both 107. My guess is that Geolander might (in caps) also be XL although not stated to be.
An interesting question now emerges:- can you have tyres which have the same load rating, but not guaranteed to be XL?
My first port of call would be to e-mail your question to the supplier - they may well be marked XL, but that has been omitted from the written description.
Let us know how you get on Mark.
Kind regards,
Gareth.
