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

Are you saying that's above the 1" that the taller tires provide?

No. They aren’t “lifted” more than a 35 truck. It’s just taller rubber. At least according to all past press releases.

I want to put the exact tires on my stock 23. Did you have any rubbing before adding your lift? I don't jump the truck but I do go hunting and very mild off-roading. Goal in 37s on stock everything but I do not want the KOs/3s. I need a 3 peak rated tire.

I didn’t have rubbing, but I only drove home and to the grocery store…less than 1 mile total. They looked like a tight fit, I’m willing to bet they would rub if you hit something right with the tire turned.

Stock suspension. R wheels with 37 K02. No rubbing so far with 400 lbs on the bed.

I too fitted 37” 12.5 k02s on my 2021 35 raptor. Only time it rubbed was super hard braking with wheel turned all the way to the right. I trimmed the fender liner for the time being and it is gone. No more rubbing. I plan on getting a new fender liner and install it once i put the collars on for 1.5” lift. I need to fix this stupid clunk from day one before modifying the suspension. Truck drives great with 37s with no ill side effects so far.

Did you figure out what the clunking was? I have that same issue forever and the dealer keeps jerking me around

Good morning!
Has anyone had luck ordering the OEM 37 through Discount Tire? I seem to be having trouble finding it on the site.
Alternately, would the local ford dealership be a better place to order/install?

I have a fresh set of 17x9 FP1s courtesy of Justin in the garage now and the 325 K03 seems like it will not be available any time soon. Current K02s are already toast after 24k miles.

Picture of the truck for credibility. Hope everyone is doing well.
