Biggest tires I can fit?

I have a 2011 6.7 FX4 f250, wanting to put 2.5 leveling kit. Keeping the stock 20" wheels what's the biggest tire I can fit. I've seen 37s w/ stock 20s on a truck and looked like at a glance it was just a leveling kit. Of coarse a dealer is trying to tell me I have to buy a 3" lift to fit 37s I just don't believe it.

Anybody's input on what you know or what you've heard would be appreciated

37x12.5 on stock wheels are going to rub the radius arm at full lock. Why not stick with 295/65r20?

Also since you have a 250, you do need to lift the rear 2.5" as well. So your salesman wasn't too far off.

With the factory offset and 37's you will rub at full lock even with a 4.5" lift...so a leveling kit isn't even going to be close to what you need. There is a guy on here (can't remember screen name), with a 2012 KR with a 4.5" lift and 2" billet wheel spacers to clear 37's on the factory wheels...his truck is white on gold and is either in the 2011 pics thread or the Carli pics thread.

To answer your question on the factory offset and a leveling kit you should clear 35's no problem...I'm sure I've seen numerous trucks on here with that configuration.

2012 F350 KR
Carli 4.5 Performance, Machined Fuel Kranks 17", 37" Toyo MT's, H&S Mini with custom tunes, H&S Cac, S&B CAI, 5" FLOPRO, EGR/DPF delete, Full replacement front and rear bumpers, toolbox, and bedrails by South Texas Outfitters, Rigid LED's, B&W hitches...and this thing is finished!

if you do a 4.5" lift and bushwacker cutout flares you can run 40" tires but they will rub on the radius arms ... if you want bigger tires, do a lift with a low offset wheel to avoid rubbing anywhere

Beware!!!! The King Has Returned
