Question about 37s vs 35s

[NoOtherHobby]

Hey all, I'm in process of planning a build for the summer on my 2020 Rebel 5.7etorque. Looking closely at the 6" lifts from both BDS (fox coils) and RC (vertex coils). As part of the planning process, I've been looking at wheel/tire combos to go with the lift and had a general question about 37s vs 35s. Stock wheel/tire weight is a total of 82 lbs (55 tire, 27 wheel) from what I've found. I'm leaning heavily toward the Fuel Rebel 6 or Method NV 305 in a double black (18" for BDS and 20" for RC). For the tires, the Ridge Grapplers seem to keep coming out on top. The combined weight of the Method wheels w/ 35s comes out to 106.81 lbs. I've seen a lot of rigs with this setup and the consensus is that running 35s is not an issue. If I moved to a 37, it ups that weight to 116.09. I've heard a lot of the pros and cons of 37s and the biggest con seems to be strain on components due to weight. My question is, does the added 9 lbs of weight going from a 35 to a 37 really cause that much of a strain relative to the increase of 25 lbs going from stock setup 33s to the Method setup on 35s? Truck sees low miles annually, only offroading is going to camping trails, etc, and towing in the summer is usually limited to the occasional towing of a pontoon boat at about 5,000 lbs all in.

I've seen quite a few people run 37s with the 6" lifts and they seem to love it but the other side of the internet tells me my truck is going to fall apart. Given the low miles I put on the truck I'm not concerned about the MPG hit. Any input is appreciated. Thanks.

Unless you got 3.92’s don’t even think about 37’s

The rebel comes with a 3.92 ratio.

Get the 37”s you’d don’t wanna look like a *****. 3.21 to 3.93? Read the infinite posts. There’s barely a difference. They don’t use plastic gears.. little better fuel eco in high of 3.21 little higher rpm in low gears of 3.92.

Well this thread spiraled quickly. Thanks for the input fellas. Anyone else have any thoughts?

I’m running a 6in bds with 3:92 gears, 35x12:50-20 nitto trail grapplers-with 20x10 wheel. These 35s run very big to size, my wheel and tire set up weighs in at 119lbs. Driving the truck down the road you would never think you have that big of a tire under you. The gearing and transmission in these 5th gens are amazing.

6” RC with vertex coil overs on 35x12.50 grapps, rides better than stock.

Nice color match on the steps ….

Thank you they are the from rough country, they came black with a semi rough finish. After about two months they looked like sh$t so I had them painted for $100.00 per step, definitely way better painted.

Considering it’s a Rebel with 3.92s, 37s are absolutely fine. Lower numerical gears will be fine as well, as long as people keep the expectations reasonable. To shave a little weight, you can run the 11.5” wide ridge grapplers if you want. My truck mostly goes to the Texas Hill Country, which is big limestone rocks, so the clearance is more important than the tread width. Contrary to what many prognosticators of the apocalypse will affirm, your truck will not fall apart with 37s. In October, I drove mine 3500 miles to an elk hunt and back, complete with rallying a lot of nasty SxS trails. All still good after 2.5 years on the 37s. Do what you want and enjoy! Merry Christmas as well!

I had 35x12.50r20” Toyo RTs on the BDS lift and it felt like stock to me. I never once thought the truck felt strained in the slightest bit! I moved up to 37x12.50r20 Toyo MTs and it’s a hugeee step up from the 35s. 128lbs each wheel. It looks 10x better in my opinion but the truck certainly is slower and overall feels more sluggish and just like a big heavy truck more than it did with 35s. Would I do it again? Yes! The look is worth it and frankly it does still drive fantastic and have plenty of power. Am I bummed that it actually did perform better on 35s in every aspect? Yeahhh. One compromise would be to do a lighter 37” D load tire on an 18” rim. Then I feel like you wouldn’t notice nearly as much of a hit on performance because they’re way lighter as a combo and because the extra sidewall & D load should really cushion the ride more than the heavy E loads do with 20” wheels!

Completely agree, these trucks are great with big tires! One interesting point on load rating: the break over between E2 and D1 happens between 11.5” and 12.5” width. E2 and D1 are both 65psi max tires, just the E2 is wider.

I’ve never seen a letter + number on a load rating? I’ve always seen D load be 50psi max and E load be 65psi max. I’m not sure what that list applies to

plenty of others out there, but this one breaks it down pretty well.

main break over is “flotation” tires. So if you have 11.5” wide ridge grapplers, they are D1… same tire 12.5” wide is E2. Both 65psi tires.
