37x12.5 Mickey Thompson's on 17x8 zero offset wheels completed

'Was just going to ask about your PSI. How were they at 50? Not that its comparable...but going from 50 to 40 on the Duraturds was like night and day, surprisingly. Hows road noise? Too bad you don't have the Carli arms, I'd be curious to know if any rubbing was happening with those.

I seem to remember the tire review I watched on these said they're literally the hardest tires to balance...and require a dedicated balancing schedule so they don't wear out prematurely. 'Pretty sure it was in this video

I wonder if Centramatic Rings would be the answer to that problem.

Mentioned they were quiet and comfy at 50 so far, and so far I see no rubbing on factory radius arm or sway bar. 😁

Got them balanced on road force machine with clip on weights on the backside, as the caliper clearance is pretty tight.
 
Found what I believe is the only remaining rub spot, which is the cross member (or crash bar?) directly in front of the tire. No trimming that haha.

Leaving the mud on has helped me quickly find the spots :LOL:

Some of the fender flare trimming I did earlier today on the rear of fender well. The CJC trimming video doesn't show a truck with the flares installed, so I had to figure it out. Just made a straight line down and used an oscillating multi-tool.

May remove a bit more where the bottom left screw head is, which will be metal removal, like the CJC video demonstrates. I'm not even sure that I'm rubbing here, but a little more clearance won't hurt anything.

Bronco, you're now a week in on running 37x12.5s on an 8" wide wheel, how are you liking the ride? Specifically interested in handling, are you noticing any issues with stability with the narrower rim (I know it's only 0.5" under spec for most 12.5" tires).

I considering going back to my stock wheels (20x8") to try and get my wheels/tires a little more tucked and the one thing I dont want to lose is how planted the truck feels on the road right now. On some trucks I've had in the past you can almost feel the tire wanting to roll under itself under hard cornering (you can see it visually after 10-15k on the tires as the outside shoulders on the fronts get rounded over/worn). My current setup doesnt do that at all (13k and just did 3rd rotation on the current tires and shoulder blocks are still sharp/square). Honestly, it's a amazing how well it tracks given how much sidewall I have with 17's right now, and I really don't want to lose that which I have heard is a risk the narrower you go. I'd be trading some sidewall which should improve stability in theory, but curious if you've noticed a change on your setup?

My alternative I am considering is going with the Method 704HDs which is 17x9 +18 offset, just not sure that will get the tires tucked in enough to accomplish the look I am going for vs. the extra cost of new wheels. Having more trouble than I thought I would selling my stock wheels so plan A is definitely cheaper :LOL:
 
Hey tex hunter take a look at the 37x12.5 x17” cooper stt tire…I run @48lbs and put 6k miles on them, still like new.

I did a 1 1/2” level block up front.
Absolutely love the quiet ride!
Method 305 17x9 (no offset) the smallest amount of trimming, backside of lower/ inside bottom of fender (used tin snips) Only time it rubbed before trimming was with snowplow on turning into a driveway apron.
Custom offsets is where I purchased tire combo from. Lugs,wheels, center caps, tps sensors and tires mounted balanced and delivered was approximately 2800$ to 3000$ very good company to deal with. I wouldn’t hesitate to use them again.

Huh? I was asking Bronco how he felt the handling was running a narrower 8" wide rim his setup, your setup sounds cool, but I am already running 37x12.5r17' Toyo ATIIIs on my truck under a Carli Pintop system with full catalogue of extras (approaching 15k miles on that setup).

I am considering going back to my stock 20x8" wheels (still with a 37x12.5 tire) as I want less tire poke than my current setup (17x8.5 zero offset Methods). However, putting a tire on a narrower rim can lead to less lateral stability, so I was curious if he'd felt that at all on his setup.
 
@Tex_Hunter : If you're happy with your current setup from a performance standpoint, and going to buy new tires and wheels in 20" just for less poke, why not use your existing 37s R17 with a different wheel in +18 or +25 instead of your current 0? Then you're only buying rims instead of rims + tires. (Or maybe you just want something else entirely, which is fair. :)

Thanks, yep, currently weighing options, not a ton of selection in the 17" +18 (or greater) offset, and the one option that I actually like isnt my first choice in color :LOL:

I still have my OEM 20" wheels so those are $0, I'd just be buying tires, but seeing if people have negative experiences on a narrower than recommended wheel before I go down that road as even just 4 37x12.5r20's are still marginally more expensive than getting 5 new wheels.

Didnt intend to hijack the thread, was just looking for the OP's experience with his setup.

I've had my OEM wheels listed on a couple forums and FB marketplace since I had the suspension done last year, still no bites so I was just running scenarios.

So far, so good! This Mickey Thompson tire and the ATIII were the only 3 peak ones I saw that were spec’d down to an 8” wide rim.
 
@BroncoHooves How are you liking the D rated MT ATs after a couple months? Highly considering those, just a little worried about the lighter load rating than some competitors E rated tires. I’ll be putting around 2300 lbs in the bed w a slide in camper. Falken AT4s are the alternative.

I really love them! Alot quieter than my previous tires and safer in the rain. 3 peak rated too.

I wasn't concerned with the tire load rating, because the two tires still are more than the rear axle weight rating.

Thanks! I’m often in snow, so the 3 peak rating is huge.
