Zero. Some dude put 315 70 17 on his base and has minimal touching as well. Just know your wheel offset will effect how the tire sits. You can see offset differences at tiresize.com
I'll give you the other side of vroom...sold my car to them. They came and picked it up a few days later. Didn't get paid within the next 48 hours. Started calling them to try and figure out what was up. Support is lacking. But you can request to go to tier 2 immediately. For a week no one knew...
Uvita is not really that remote. But it is kinda far from San Jose. I broke down in matapalo once. That's pretty far out there. . .To be honest man a jacked up yota will probably be your best bet for future service and ease of operation. Plus a new bronco will probably draw a ton of attention.
Now those boys know how to make a bumper! Thank God someone came out with something that doesn't look like it belongs on the front of a train.
I bet they have good customer service too!
