Why are wheels so hard to figure out?

[Jt-wrx]

Moto Metal rims 17 x 8 with 6.062" backspacing and 40mm of offset. The tires are Continental Terrain Contact A/T's size 315/70-17.

golly that's a thing of beauty, can see more of this 'positive' love over on my IG @gladiatoryyc, mine is a sport-s with 37x12.50 on stock wheels plus 12mm wheel spacers giving me approx. 5.6" bs or plus 32 on the 17x7.5 stock wheel, my sidewall pokes just a bit further of course but also have the narrower axles and fenders of the sport, you have the max tow, which is same width axles as rubicon but i think same fenders as me plus the little lip in your picture

for the fatties i run i had to put a few washers under the steering stops to limit the control arm rub but it was worth it to keep things tucked to where the edge of the tread is in line with the top of the fender but the side wall pokes...just the sidewall pokes, that is perfection

I heard someone was getting poked and felt like I had to “poke” my head in as well ....

Look for the right bolt pattern and you will be fine. Offset and back spacing ......whole other discussion.

For reference. These are 17x8.5 with -18 and 4.04 bs. Tires are 37” Cooper STT Pros at 13.5x17 ??

how do you like these stt's so far? I'm about to pull the trigger on some of these, also going with the 13.5 on AEV's Bora beadlocks

I've been moving in on the No-Poke vs. Poke spectrum. When living in the arid SW, Poke was fine. Now with the sloppy roads in mountain NW, with sloppy dirt roads, I'm trying to pull the tires back in.

Unfortunately, slim pickings on wheels with 5"+ backspacing... unless you like AEV. I run Pintler beadlocks on my JK, but was looking for a Black Rhino Abrams type look this time around on my JTRD. The only wheel I could find in that look without negative offset was Warn Jackhammer, 8.5x17, 0 offset, 4.72 backspacing. Due to a time crunch, I had to pull the trigger on them and 35x12.5s before the jeep was delivered.

They look absolutely awesome, but not completely happy with the 1.25" poke. I'm getting so much splash, I had pitted the plastic rear fenders from thrown gravel in a matter of weeks.

So, to wrap my head around backspace/offset, I actually took out graph paper and drew a cross section diagram of the following for comparison:

- My Warns, 0 offset, 4.72 B/S with 35x12.5 tires - 1.25" poke

... with that as a reference I computed...

- Stock Rubi wheels, 7.5", +44mm offset/6.125" B/S, stock MT tires - should compute out to about 1" or so inset from fender... which seemed high to me. Didn't seem to remember them being so far in. Anyone have a real-life measurement on this?

- AEVs at 8.5", +25mm / 5.72" with 35x12.5 - should have about .25" of poke, if I computed it right.

So I'm going to try some 35x1 1.5 on the Warns on the JT and it should get me less than .75" of poke, and Ill see if that cuts the slop enough. If not, I might take my AEV Pintlers off my JK and try them on the JT to see if I need to go that route.

I was concerned prior to install Of being noisy, etc. Now several weeks in, 100% happy with their performance on and off road. I can ride with the rig wide open and no Issues.

We’ve run non off road Coopers in the past and have been very pleased. These don’t disappoint either.

Im even getting nearly 18mpg These last several weeks.

awesome thanks for the feed back

Couple other wheels with good backspacing are Quadratec brand aluminum wheels and KMC. KMC makes a couple with +18 which is around 5.5” in a 8.5” wide rim

Just a thought, KMC has wheels in their Offroad Tech Series that are 17x9 +18 (5.71 backspace). A bit more poke when compared to AEV (I believe around 13MM or 1/2 inch more poke - 3/4 inch total), but about 12MM less than the Warn wheels.

That's a pretty ideal spec imo. Have a look a Black Rhino Mozambique...nice simple 7 spoke design with 5.9" backspace and they are lightweight. Like 26 lbs for 18"x8.5" and 28 lbs for 20"x8.5". I've got the 20" on order.

There is one guy here with a red jt running the black 18" mozambiques i believe, just search here for black rhino mozambique to find his pics. It's a +30 offset on 8.5" wide wheel and therefore 5.9" bs. Should be approx. 1/4" more out than stock wheels.

How’s the clearance on the inside with that much positive offset and the wide tires?

 

[Jt-wrx]

if control arms in same location in relation to frame on sport and the wider axle rubicons/max-tow models i'd wager with 35's you won't hit the control arms on the wider axles on that 6" backspace, you'd likely just be touching or possibly not on the narrow axle, i have experience with the narrow axle and 37's on stock wheels and they definitely hit the control arms as you approach lock and required about 5 washers under each steering stop and with 12mm (1/2") wheel spacers to mimick wide axle models i was able to drop the washer count down to 2-3 under each spacer, that's with stock 6.1" backspace wheels and 37's

5.5-5.7" bs for 37x12.5 is the sweet spot to stay relatively tucked and not rubbing control arms, the mopar wheels are 5.22", i find those look a little too pokey but still better than all those 4.5" bs skateboards

You rock! Thanks.

Do you have a few good photos of your rig with the Warn Jackhammers?

Here's a couple I snapped between snow showers, with Cooper Discoverer AT3 285/75/17. Love the look of the warn wheels, but at 0 offset, I still get a little poke with 11.5 wide tires. I didn't get the angle quite right on the poke-pic, but if you look at the rear tire you get a better feel for it. I washed the truck yesterday, then snowed this morning before a drive to town.

 

[Jt-wrx]

if you can see and scroll the pics, especially in the second link, i did down the side shots front view and rear view to show poke, you'll see what black rhino mozambique 20x8.5 +30mm (5.9" bs) look like with 37x12.50 falken at3w's look like on a sport s, mopar plus 3/4" spacers up front, the sidewalls poke and the edge of tread looking down from top of fender is inline with each other, any more poke than that and you're slinging crap in the windows and all over the vehicle, sport have narrow axles, max tow and rubicons will be out another half inch but they also have wider fenders to compensate

because i have the narrow axles i did get some rub on control arms at lock but solved quickly/easily with a couple washers under each steering stop, i don't think the max tow or rubicons would have this issue with 37's

tough to beat the overland running boards, they weigh nothing (10-12 lbs each), don't rust, fit tight, and block the crap/gravel, i cut front rokbloks with tin snips to block off the open gap between fender and running boards on the front, works great, unless you crawl and need steel protection, overland model side steps are best imo, also great door ding protection
