Help!!!! Unsure if new wheels will fit

[Coreygoodwin04]

Hey y’all, I’m currently looking at Method MR701s for my 2020 TB. It has a 4 inch Fabtech lift and currently on god-awful Fuel rims from the last owner. I would like to purchase the 701s in 18x9 with 5.8 inches of backspace. These all meet the minimum requirements of my lift (18x9 with 5” of BS) but on the method website, it says “Casting variations of the brake caliper may result in an incompatible fitment”. Anyone know what this means and whether or not I can buy this setup? Planned on putting BFG K02s 295/70R18 on which should fit perfectly but this message from Method is confusing me. All help is much appreciated!

I think the issues were related to aftermarket 17in wheels not 18in. But I’m not an expert, just a dude with a nice truck.

The 19+ trucks have a “bump out” on the caliper that interferes with certain wheel styles. It will rub on the rear of the wheel face, not sure if that makes sense or correct terminology. I’m not sure how to tell which ones will or won’t though.

I’d look for reviews/verified buyers with that particular wheel and matching vehicle or check out custom offsets website for the same.

Great advice. I’ll report back with what I find!

you should check with the dealer who will mount your tires and install the rims they would know . and whats wrong with Fuel love my 851s

Yes large fixed calipers are pretty much always tricky when it comes to aftermarket wheels. It's not the diameter, offset, or backspace that's the issue - it's the spoke profile...you can have the right diameter, width, and offset and still have the spokes hit the caliper simply because they don't flare out enough near the hub. The part that really sucks - you either have to find someone who has successfully put the wheels on a T1 truck or you have to be the guinea pig.

One approach i've tried before when I had to be the guinea pig - I just ordered one wheel, and then test fit just the wheel to make sure there was sufficient spoke clearance. I actually called the dealer in that case to let them know what I was doing and they agreed it was a great idea.

That is indeed a great idea. I don’t have much time as I’m leaving for school soon and wanted to get the work done while I’m at home with access to my other car. I ended up getting the MR701s 18x9 with a 3/8 inch spacer. That’s what one website said to do anyways… We’ll see I guess, I’ll report back as soon as I know

Fuels are great but I just personally like the Methods better. Going to get a 1/4 inch spacer to solve the brake caliper clearance issue and if that doesn’t resolve it then I’ll get bigger studs for a larger spacer or sand down my brake caliper slightly. I think the towing package makes for a wider caliper and I don’t have it so in theory I should be in the clear. Your truck is a beauty, just down to personal preference

Brakes are the same on all 1500 models. Towing package just has heavier duty springs and higher gear ratio. I run a 5mm(1/4") billet spacer on my truck to clear the caliper since the wheels are aftermarket ones I had on my 08 Avalanche. I bought 2 sets of 17" wheels and they both clear the caliper fine with no spacer. One is Level 8 brand from Discount Tire and the other is Falcon brand. I need to get my 2" lift on so I can install them with my 35" tires.

 

[Coreygoodwin04]

Update: took my truck into a discount tire (as recommended by method wheels for the best price) and after much research from both parties, we determined that the 17x8.5” MR701 wrapped in 285/70 K02s. Clipped the calipers and wouldn’t roll an inch out of the place! Can’t believe they didn’t notice it hitting during install. Hope my rims aren’t damaged, they ordered spacers (they paid for them which is nice), just hope my rims are okay. It was a bit of a cluster 10 minutes before closing when it didn’t roll out of the shop haha. Oh well, it will be great once finished

Why didn't the clowns test fit a wheel BEFORE mounting any tires??? That's what all wheel manufacturers recommend since they aren't returnable once tires have been mounted. I test fit both my Level 8 and Falcon 17x8 and 17x9 wheels and they clear the calipers just fine with no spacers.

Size comparison from stock tires if that helps

 

[GETGONE]

I always forget the stock 18's are only 32" whereas the stock 20's are 32.5" on Trail Bosses(265/60/20) but are a true 33" on regular trucks(275/60/20).

It kills me that GM put these trucks out with 32s when the midsize Colorado Bison gets factory 35in tires

ESPECIALLY on the 1500 ZR2!
