Tire/Wheel Discussion

There are sidewall repair kits though I've never used one and I've heard you should probably carry an angle grinder and flappy wheel too to prep the sidewall.

Regarding cell reception, iPhones and some android phones come with satellite texting capability. Still, getting towed on a dirt road is not cheap!

Yeah, there are a variety of satellite comms devices one could bring along. But even so, you could easily be sitting around for hours waiting for a tow truck to appear, so it's not just a question of money.

Okay, but which tires work best for a minivan?

FWIW, the new Pirelli P Zero PZ5 that will be on the largest Gravity wheels has a considerably squarer shoulder than the PZ4 it updates. This is interesting, as European tire brands usually stay with more rounded shoulders due to the more pronounced crowning of most European roads compared to U.S. roads.

I have a dumb question -- I was just looking at R1S specs (comparing power ratings), and I noticed that the *smaller* wheels there are less efficient: 22" wheels have 410mi EPA rating, while 20" have 370mi. Is that because of the weight of the rest of the all-terrain package, or the fact that the 20s are all-terrain? (Yes, I know this is a Lucid forum, not a Rivian forum...)

So you stole Fred Flintstone's sports car, didn't you?

Oh, I didn't realize. It came up on a google search for Henrik Fisker's next prototype . . . .

All terrain tires are much less efficient than all season tires.

The All-terrain tires are inefficient on rolling resistance because they need to grab onto gravel and rocks They also have a lot of give in the tread to compress.
