37s on level no rub offset
FYI, if you plan on fitting 37s on a level kit, they will rub. They don't rub enough to hurt anything but bothered the crap out of me. My solution was finding a wheel that still keeps them tucked under the fender. A +20 wheel is perfect. No more rub and still fits inside the fenders. I personally didn't want to stick out of the fenders.

The picture is a little deceiving. No flares needed.
20x9, +20 offset are perfect. I went to the shop and mounted up a 0 offset and they got way to close to bumper and inner fender. +20 with 37/12.5 are perfect for me. If I had to do the level kit again, I would probably go with a 3 inch. There is still a lot of rake in the truck with a 2 inch level. I'd probably go with the WICKED LEVEL. (google it) they look really nice. A larger level would give you even more room.

+20mm offset is the answer for anyone(myself included) who wants an after market wheel while trying to keep as much under the fender as possible. Vs the stock +40 8" wheel, a +20mm 9" wheel only moves the wheel .29" away from the suspension/radius arms.

I looking at going to Toyo 37x12.5r20 mt tires too. How are you reprograming your speedo, odometer and correction transmission shift points?
Ford computer does not go larger than 275/65r20...the largest tire size they offer (which is what's currently on my truck). I'm worried about the 37's in transmission shift points, speedo, odometer, navigation, etc. if it can not be reprogrammed. The 37's cause a 7.5% error.
What did you guys do?
Since you cant enter a larger tire size in Ford computer than the 275/65r20, luckily I have 3.55 rear end...can Ford dealer re-flash computer to 3.31 rear end?
This would correct all but about 0.5% error which is close enough.

Thanks ledman based on your pictures I will be getting +20 offset wheels. Not likely 37" tires but the wheels for sure with 35" tires.
Why are people concerned about correcting the speedo? Just drive a tiny bit slower if your concerned about the cops. My trade in truck based on numbers I had 9,000 more Kim's then showed on the odometer. That's money in the bank is it not?
