I think the tire is wider, no?
We are running an identical tire size to stock but with a 1-inch wider wheel. The height of the wheel/tire assembly if you were to lay it on its side is unchanged.

Hi Everyone!

Just a friendly reminder that our pre-order for these wheels ends at the end of the month. We've had much higher than anticipated sales which has been great!!

We can't wait to see the wheels installed on various R1's all over the continent - both on-road and off.

Feel free to contact us for details or order on the site.

Have a great long weekend everyone!

I am also interested in this answer.
Sasha has yet to finalize the design of the aero covers for the MegaTerra wheels, but we have just received a run of these covers for our MegaMesh wheels in gloss CF.

I would personally be inclined to go with solid-style aero covers for functionality. This truck has enough regenerative braking that I wouldn't be worried about brake cooling even when towing a heavy load. The glossy finish is nice, but we will likely be sticking with matte finishes moving forward.

In other news, our MegaTerra wheels are now being delivered and installed on trucks! The first batch of photos we have received is from David on his overland build R1S.

The Satin Anthracite finish has the advantage of complimenting any paint color. This is why we suspect it has been the most popular configuration.

We even received another unboxing photo just yesterday!

These wheels will to be wrapped in K03s and the owner, Chris, has shown interest in jumping his truck at least and high and far as we did. That's cool to hear, but be careful. Good luck bending one of these wheels though!

Thank you for everyone's support and have a great weekend!

Any plans to offer this wheel in 9” or 8.5” wide configurations?

9.5” seems guaranteed in the long run to get rock rash off road or even curb rash around town.

Not really interested in bolt on protectors to solve a design problem.

It is a beautiful looking wheel, id buy a set if they weren't so wide.

Well done. These have a rugged off-road style with an EV flair!

Love these new wheels. Highly recommend them.

Tire business I worked with say they are the nicest set they have worked on (they work on some high end custom vehicles). These are Amazingly accurate and completely balanced out of the box. Detail work is spot on. Their attention to detail all around, not just the outside people see. no concerns running these anywhere I want to go.
I mounted them up with BFG - KO3 in stock size. Very little weight needed at all to perfectly balance, as the wheels are so good to start with.

No jumping, yet. But good and smooth up to the limiter. :)
New tires sound like velcro when taking off ("old" wheels are stock 22's).
Some efficiency hit going from 22s to these 20" AT as expected. But not as bad as I thought it might be. Dirt roads and trails, and snow use much better with these tires as well. Wheels look good doing it.

A bunch of photos attached for anyone that wants to see my set.
