Custom 20” Cyber Rover Wheels with KO3 tires

[Oden's Beast]

That seems like a solid deal. Can you explain again why one would choose 20” over 18”? Is it so you can use your current factory tires?

My primary reason was so that any tires for the CT that I ever had, would fit any rims that I have for it. I also figured it was designed and tested with 20’s by Tesla engineering, so it’s a pretty good default for it. That (and this is just my personal opinion), the 20’s just look a little better to me. It’s for these reasons that I took the long path to get the 20’s (as they had 18’s in stock when I had ordered them).

Very valid points. I’ve often wondered about that, aside from profile it’s mostly unsprung weight that affects the suspension, what weighs more? I’m assuming more rim with less rubber but rubber isn’t always that light either.

I have the 18" in gun metal. Love them!

Does anyone know if the martians with tires are a significant unsprung weight change from the OEM setup? Up or down?
I just want to convince myself I’m not worsening any engineering for the sake of looks but I really do love them.

You absolutely could use them, but not without accepting compromises that I was not wanting to make. While they look identical, there are definitely some physical differences. Most important to me, the OEM TRX wheels just are not available in 20". I specifically wanted 20" so that all my loose tire sets are interchangeable. I actually waited quite a while to get the 20" ones. I also actually prefer the look of the 20" rims vs. 18" rims. I know hardcore trail guys prefer 18" as they can be more supple on-air downs for large rocks, etc... I don't see me ever attempting trails like the Rubicon, so to me this slight performance advantage for extreme off-roading was immaterial. The standard OEM TRX rims come as bead-lock capable; they come with a beauty ring (just like the Bronco's wheels do). So, to have actual bead locks, you have to buy an upgrade to an actual bead lock ring (also like on the Bronco, which then adds ~$200 per wheel...the Martians come standard with a true bead lock ring). As you mentioned, the larger offset of the Martian wheel is machined directly into the wheel (+ 40mm), this pushes the tire out slightly to really enhance the look (this was purposely done by Martian for the CT for this exact purpose). You could do this with spacers (TRX have an offset of +19mm), but I don't really like using spacers (especially on an 800 HP plus vehicle). The center bore diameters are also not the same (77.8mm TRX vs. 84.1mm Martian).

I also still would have had to do the color change, as the stock TRX rims were not available in the dark bronze either. Additionally, I got a crazy good deal on a set of 5 wheels from Martian, it was Black Friday pricing, with a bonus option to get a fifth spare wheel for just an additional $100. They typically have really good deals/promotions on most major holidays.

If you really like the 18" wheels, OEM TRX's really are not a bad option to consider.

Thanks for the info. I already have a set of KO3s in 18s but haven’t decided on a wheel.

However, the TRX wheel is more aggressive at +19 compared to the Martian wheels at +40 offset.

the TRX wheel would poke 21mm further than the Martian wheels.

A couple members have asked about my trucks new wheels. They are 20” Cyber Rovers (by Martian Wheels). As is usual for me, they were not exactly what I was looking for, so I ended up tweaking them a bit more to my liking. The style is very similar (if not identical) to what is on the Dodge TRX. I wanted them in dark bronze, but they were offered in a much lighter Satin Bronze (also in Satin Black and Satin Gunmetal). When they came in, I immediately disassembled and sent the actual rim portions out for aluminum oxide media blasting. These were then re-powder coated using Prismatic Colors CT Bronze powder. I left the actual bead locks in the as ordered color (Satin Gunmetal). I replaced all the black coated carbon bead lock bolts with new brushed stainless steel bolts. I also made custom CyberBeast (Cerberus) logos that were milled onto stainless steel disks (these were powder coated prior to machining). Once finished, these were then powder coated in the same satin clear as the wheels. I removed the Martian Wheels logo from the inserts and replaced them with the new custom ones (using methacrylate adhesive). I completed them by mounting a set of BF Goodrich KO3’s tires onto them.

I think they turned out really good, and were exactly the look I was going for! They have completely changed the aesthetic of the truck.

I also include some (way to many) pictures.

Beautiful!

Your 100% correct, the OEM CT wheels have an offset of +58.5mm, the +40mm on the Rovers push that outwards 18mm, going even further to the +19mm pushes it out even further. It gets a little confusing as you can have both + and - offsets, and when going positive, the smaller the offset number is, the further it pushes outwards. This is cementing that I made the right choice. I think that would be just too much for my liking!

Dang it @Oden's Beast . Now you have me lusting after these. You might receive a strongly worded email form my wife.

based on this , have you ever considered 22? or are they not available.

I’ve not seen this style available other than 18’s and 20’s.

@Oden's Beast , two questions, what did the powder coat job cost you?
Did you find a good blank cap which was the basis for your custom beast logo?
