Welcome to the forum. Congrats on your new TC.
All your mods look very cool. You've done a lot in a short amount of time.
Re tires, over the years there have been a sprinkling of posts on Geolander tires for offroading adventurers. Do a Search on those to get ideas.
See the thread below as well.
Good luck!
I just had the tema4x4 (Russian) 30mm lift put in as well as BFG AllTerrain KO2 tires and it looks pretty good! Lots of room for those bigger tires and plenty of ground clearance underneath.
