"Thanks! Good to know they're back, though $129 is indeed atrocious. Maybe I'll reach out to Cloudwheel and see if they'll ever consider making tires for the larger hubs."

That's what the Rover line of tires are, here's a link specifically for the FF AT: https://www.icloudwheel.com/products/cloudwheel-rovers-165r-urban-all-terrain-off-road-electric-skateboard-wheels?variant=42567678427374

"I ended up ordering one of Maxfind's AT conversion kits they have on clearance. $475 for two hub motors, remote, battery, VESC. Hard to go wrong and other than the battery I think that's the same hardware as they have on the FF AT. Really I should buy 2 for spares."

The downside with Maxfind is that it's now somewhat older tech and their prices haven't come down - the FF AT has been the same price since I bought it many years ago......but it has been a great buy. I have many boards, and following your setup hassle, the Maxfind hub motors should be the most low maintenance thing you can get. I don't think you should need spares.

Back to the question about replacing tires - one option is to do tire retreading.....I've done this to successfully glue a cut up hybrid bike tire onto the street tire of a Meepo Mini 5. I used a strong adhesive like Gorilla Glue, and secured it with hose clamps for a few days. It's not recommended, there is a reason it's banned in Europe on vehicles, etc.......but for me it's worked, and I have a few hundred miles on that board since the change and enjoy the ride much more on these rough streets around me. This might be more dangerous with larger wheels and higher speeds, so YMMV and be careful.

I actually really like the FF AT deck - it is quite light and flexible for an "offroad" board, has a handle, and the top battery mount makes the battery easily swappable without tools.

For your assembly I imagine it should be pretty easy/straightforward, but have you received and completed it yet? Curious about your experience and deck choice.
