Installed 37's on Gen3 35 Raptor - no issues.

[hyrepower]

I have this tire size on my 35 truck.

Fuel Block 18x9 +1 offset
Falken Wildpeak AT3W 37x12.50

There was definitely rubbing before RPG 1.5. After RPG there was still some very minor trimming to do. Mostly the inside bottom portion of the flare.

It rubs a pinch weld slightly if turning and going over a curb just right. No rubbing on the pinch weld during normal driving.

I will probably trim the pinch weld or maybe knock it back flat and out of the way, not sure yet.

I’ll take a few pictures of what I trimmed tomorrow.

Falkens are the biggest tires made and +1 mm offset is a bit too much. I would say +6 mm to +18 mm would be ideal.

That you for the reply. I appreciate it. What’s crazy is that I don’t even have my truck yet. I’ve been waiting for so long that my dealer is giving me a 37 that’s in transit instead. No mark up.

That doesn’t sound like a bad deal!

I had a 2021 37 with an RPG perch. Used the factory 37’s with Fuel Block 17x9 +1. I don’t remember rubbing with that setup.

I’m in the process of switching to KO2 37’s and back to a 17” wheel.

This setup will be for sale if I ever get approved for the Garage Sale. Falkens will work with minor trimming and RPG

You will have no issues with BFG KO2's, they are a bit smaller than the what you had. What made you switch back? Too much rubbing? It was a good looking set up. But I guess it needs to work and not just look good.

When you guys mention you may have to trim a bit, is there a way to trim without making a mess or an unsightly hole? I mean, it is plastic. Why am I thinking trimming, at least for a street truck, should be avoided?

 

[So-Cal-Al-52]

You typically trim the pinch welds behind and under the plastic wheel well liners in the front. If you are strictly street driving then trimming may not be needed. If you go off-road and compress the suspension while turning then you might have rubbing. If someone performs trimming that knows what they are doing then you won't notice and most of it is hidden.

I am switching back just to go to BFG again. I have 99% clearance now with minimal trimming, so it will make a good set for someone.

New with sensors and lugs I paid around $3500. I’ll probably ask $2,400 when i post them for sale. Great looking setup for $2,400

Just put Maxxis Razer AT 811 - 37x12.5x17 on.

Had the same tire on my gladiator, so I knew I'd be pleased with it.

I'll be the odd man out. I've rid myself of 3 sets of k02's - never liked them Personally, so I've tried quite a few types.

I have a level kit RPG that came with the truck -o idea what size.

But..

Tires don't rub yet, that I know of.
I'll get some pictures later..
Was -30/40 today

Has anyone swapped in a longer bumpstop up front to restrict travel?

Update:

- Installed the 37x12.50x17 on factory wheels.
- Executed a height calibration. Rises much better in my opinion, maybe it's a placebo in my brain.. no idea.
- Speedo is off 3mph at 75 mph, nothing major.

Here is where I'm confused. I contacted my dealer, asked them to calibrate my speedo. Their response was they have not been able to calibrate speedometers since the 2015 model.

I have forscan, so I plan to tackle it - if anyone has any advice on that, please drop a note, but I do intend to scour the forscan thread and google sheet but I'm always open for, "Oh do this instead".

Anyways, super happy with the 37's - can't tell anything wrong with power so far - might run with the cobb tune next...
