My point is this:
When the UA was in it's infancy, the common tire size was 35-37" which is doable for the same rigs that are not often trailered to their destinations.
Now the tire companies are creating specific set of tires just for the UA and giving them out for publicity for the the competitors to run. Now the common is 39-42" size in the UA.
When you look at the common rigs out on the trails, running 39-42" tires, arguably half of them are running stickys and most of them are trailered there.
Sure I would drive 1000 miles if I had a big name sponsoring me and giving me parts and tires for the trip. My rig is street legal and could be done, just air up and pull the drive slug. To me it's not worth it for he investment I've made in the rig.
My whole point is, both the TTC and the UA are not realistic to what is commonly being wheeled with anymore.
After having dding my jeep for years, driving to wheeling spots, and now trailering. It is far less stressful and more fun to go out and wheel and if somethjng breaks, to put it on the trailer and fix it that night, or take it home. Either way, I'm making it back in time to go to work on Monday, without the stress of locating parts and fixing it just to make it back home...
I other words I miss the real truck challenge...
