Doing some more research for the 33" tires idea -- sure the Juke is handling fine on the '30s' I have on it, but I've been thinking about it a lot, since this is my daily driver I should probably put a little more effort into keeping it at least somewhat reliable if I'm going to go taller, wider and heavier. I'm starting to realize just how absurd it sounds to take a Juke from it's stock tire size all the way to 33s; most jeep wranglers come stock with 29s or 32s depending on trim, and if they go any higher than 35s they usually re-gear, and that's only a step up about 3".
The stock Juke has 27's (being generous), so a 33 big big step for this vehicle. With the increased drive ratio and the increased rotational mass, the next 3" step, while only another 3" step in height, is going to have an almost exponential effect on the car.
So, I weighed the wheel with the 30x9.5 was about 64lbs, the tire listed by Nitto is only 34lbs, so I'm guessing the stock rim is about 28-30lbs.
The going weight for a true 33x12.5 regardless of rim fitment is about 70 pounds a piece, but digging around on Nitto's sizing chart I stumbled upon a miracle of a thing- their 305/60r18 ridge grappler, at a much lower load index, that I can take advantage of being such a small crossover - listed at
50 pounds - that's a 20 pound saving for what comes out to be a quarter inch difference in both dimensions-- that'll play. The 305/60 is unique to the 18" rim size, and none of the others come close to that weight without going back down to 9-10" in width.
This limits me in wheel size to 18" rims, the annoying news being there are plenty of wide wheels for the 95-06 Jeeps that share our lug pattern, but those are almost all 16" or 17", so any other rim that I find would need an adapter or a spacer. One wheel I was looking at was the Black Rhino Overland in 18x9.5 with an offset of +6, and on my CAD setup I simulated an adapter of 18mm, which turns out to put it at the perfect offset to keep the tire from running into the front subframe, and just barely kiss (minor rubbing) the firewall. While I feel like there is still room to improve on fitment for larger than 29.5" tire with the stock geometry, this setup makes me pretty sure that 33" is the absolute biggest that will actually fit with modified control arms and stock axle lengths.
The 18" Black Rhino rims come in at about 33lbs a piece though, which seemed heavy for rims, so I figured I could find better
A quick look through Fuel's catalog and I found out their 18x9 rims are
44 pounds a piece, and suddenly 33 doesn't sound that bad.
That still puts my wheel and tire combo at an est. 84lbs, which is staggaring for what is basically an AWD hatchback, but at least it isn't 115+lbs if I had absolutely no better judgement.
Guys really though, I'm 5'4" and I weigh 120lbs. I
don't know what I would do if a single tire weighed more than I do.
There IS room to improve hopefully- several days of digging and I have found a flow-formed wheel by Motegi that has a somewhat similar split spoke design to the Overlands. They look a little spindly from the face, and a bit less aggressive than an offroad rim, but they do only weigh 24lbs for an 18x9. That would be
74 pounds per wheel.
74 pounds is really close to the 64 I have now, so that's basically NASA level lightness right there.
The load rating is only 1280, which would be plenty for any other Juke, but for any offroad shenanigans, I wonder if it will be enough.
Wow I'm surprised you read all that, it's basically just me rambling my way through an information dump
If you made it this far I would really appreciate it if you could post some nice 18x9s you find- concave preferably in the range of 0 to -10 offset (but I would be running a spacer for the Motegi's anyway). Bonus points for lightness, open to a lot of designs you think might look good on the Juke. This might still be a year or so out, so we've got some time.
