DIRTY SEVEN CLUB

Anyone with 37s bent their strut towers or frames?

I ordered 35s because I’m still on 4.30s. 5.29s and arbs and I’ll likely go to 37s next.

 

Took the family camping in Trona over the weekend. Really diggin the truck after the regear, now curious to see how it would be with a supercharger

 

Nice looking truck! What did you go with in the regear?

 

Revolution 5.29's with Powertrax Grip Pro

 

Haven’t yet. But I’m not rock crawling or hucking jumps

 

Not yet but I plan on adding an engine cage and full frame reinforcement. I do jump mine occasionally.

 

many have =)

Will be joining the club soon

 

Hell yes! You'll love the tires

 

Great choice in wheels and tires!

 

Thanks guys.

Rey's MT Baja Boss setup and from his personal experience with it, convince me with the Boss MT.

 

Same 37s but some exterior updates.

 

37s loaded in the truck. Appointment tomorrow at 8am to mount them…

 

And they’re on. This place is a bad influence on my wallet

Cut up the plastic and will do the pinch weld tomorrow.

 

Helluva rake you got there

 

Driveway on a hill and airbags still inflated. Actually thinking of ditching the bags and going timbren bump stops

 

I managed to get my mudflaps back on today... Hacked up the front ones to fit but rears were fine in stock config.

 

Looks great! I love the KM3s. Mind giving me an actual height on the tires? I know BFG run a little short and I’m curious what yours are at. I think that’s my next tire!
Thank you!

 

Thanks! I really like these tires! They balanced great, they ride smooth as butter and they look pretty badass.
I think the specs on them say they are 36.5".

 

any one actually compared 37s tires side by side? I am wondering which MT and AT are the smallest in size. I know km3 and ko2s are on the smaller side, is there any other brand/model that's similar?

 

Hell yeah

 

How do you like your KM3 so far? thinking of a small 37s, and debating between ko2/ko3 or km3

 

I know you didn’t ask me, but I have over 30,000 miles on my KM3’s and can comment on this. I absolutely love them! The ride quality is exceptionally smooth, tire wear is even. And road noise is minimal for a mud terrain tire off road traction is excellent as you would expect with such a big name off-road tire. They do run a little on the small side, which I don’t think is a bad thing when you are trying to stuff a big tire with minimal lift. I will definitely be getting another set when these eventually wear out. I still have approximately 40% tread life remaining. I should mention that I do a lot of freeway driving with these miles. But I do live in a mountain town, and spend a fair amount of time off the pavement. I run 38 psi cold front and rear, and only see a 4 psi increase in pressure when they are hot.

 

I am pleasantly surprised how well they ride and handle. I expected a big drop in performance going from the 35" Nitto's to these 37" BFG's, but honestly it's very subtle. I can only surmise that the Nitto's were very heavy for the size and the BFG's are very lightweight for the size so that may have offset the increased diameter.
They balanced just fine and have zero vibration.
I believe the guy did a "road-force" balance. There is 6oz of weight on one wheel, but the rest are 2oz or less. I imagine he could have used less weight on that one wheel if he moved the tire around on the rim... but who knows... it rides smooth as it is.

I had my boat hooked up last weekend and the truck pulled it just fine. Havent had it on scales but probably around 8000lbs with the steel trailer.
I see no need to regear from the factory 4.30's... since 99% of my driving is just a 25 mile commute to work 4 days a week.

Jury is still out as far as tire wear is concerned... but if they do OK I will definitely replace them with the same tire and size.

They are a little more slick in the rain and obviously are a little noisy at highway speeds but nothing unexpected or intolerable. This is just how mud tires are.

 

Thank you both for the great insight! I am riding on 35s Geolandar MTs, and love them, the itch to 37s is starting to get to me especially after test fitting a buddy's 37 KM3 on mine and saw no rubbing (although very very close) even on full lock and a 4 inch ramp (see pic below). I am okay with the noise of the MT but would not mind a little quieter ride, my commute is also about 50miles a day (paved roads) and I do offroad maybe once every other month. I am completely happy with my power output feel like, and I don't drive mine any faster than I have to haha. With the KO3 in the horizon, I am seriously thinking of going back to AT for the quieter ride and maybe better snow/ice performance (I live in the north east).
Current setup


Test fitted 37 km3

 

Honestly my 35" Nitto Terra Grapplers were not that much quieter... just a higher pitch singing as they went down the highway.
If you are sensitive to the road noise, these are probably no worse than what you already have on the truck... so there's that.
I dont mind it... but im sure my wife will b!tch about it the next time we are on a long roadtrip.

 

Sounds like you have a rattle in your passenger seat like I do. I only hear it when she is along…

 

I’m running the km3 as well and have about 7-8000 miles on them. Super smooth. Not loud. I do have the 13.50 bc of the deal I got on them. I do rub some things with a +25 wheel. Maybe the 12.5 wouldn’t be rubbing but it would be close. First time I’ve ever ran this tire and when I need new tires if I can get the same deal I’d def be buying them again.

 

Hey guys hunting for a set of wheels to try to run some new 37's. I have a BMC and my front bumper has been spaced out along with pulling the front plastic in an extra inch or so. I was able to run 35's on zero offset without rubbing. My question is should I go with a plus 25 or plus 35 to try run some small 37's. BFG's or Toyo's at 36.5 and will I rub? Currently on 285/75/18's with a plus 18, actual diameter is 34.8" and no rubbing at all! May have to do an aftermarket bumper. Any experienced input would be greatly appreciated. Factory UCA's as well. PIC of current set up. Thanks
