20x9 with -12 offset & RC2.5 -- which tires?

I just ordered up a set of 20x9 wheels in a -12 offset (I wanted them to stick out a bit, as I'm added fender flares to the truck). I have a Rough Country 2.5" level kit installed.

I really want to get a set of the Toyo Open Country M/T's.

I've been digging into wheel and tire threads, but all it does is make my head hurt. What's the biggest/beefiest tire I can wrap the 20's in, that won't cause me to rub (don't really want to ziptie, cut, or mod if at all possible).

Thanks in advance!

You should easily be able to fit a 275/60R20 in there (32.99x10.83x20) The K2XX trucks have more room under the wheel wells than the NNBS for sure, and I think also the NBS trucks.

I don't know whether you want a tire that's wide, or tall....kind of a tradeoff in this case. I've seen guys fit a 275/65R20 (34.07x10.83x20), but that was on stock wheels which have around a +24 offset IIRC. So those wouldn't fit on a 9" wide wheel with a -12mm offset.

IMO, I think 275/60R20 would be the perfect fit for you.

EDIT: Just checked, the M/T doesn't come in that size, but there are other options on the market for sure...take a look at BFG KO2s, those are a great tire, as well as the Toyo Open Country A/T II.

Awesome, thanks for your input n8dh! I don't mind wide or tall, kind of want the max on both without any rubbing.

I also realized that while I have my truck in my profile, I didn't include it in the post -- I have a 2014 Chevy Silverado Z71 (with the RC 2.5" leveling kit) in case anyone is wondering WTH I'm driving lol.

Thanks!

I saw a local guy with a 2015 Silverado running Toyo Open Country AT II's in 305/55/20 on stock wheels and a 2" level. I'm running the 295/55/20 Open Country A/T II's on 20x9 0 off sett my 2013 with a 4" lift. I think you need at least a 285.
