just wanted some opinions on how they feel before I splurge into buying them.
also some pics and info on rubbing is appreciated. btw, i have a leveling kit and have done the pinch weld mod.
Those should fit fine even w/o the pinch-weld-mod on stock 18x8, but BFG recommends an 8.5" rim minimum ... of course lots of members run 325s on the stock 18x8" rims.

idk
I've been very, very, happy with my KOs but they have gotten very slick in their last 10K miles of tread life, (in the rain), so I'm going to try the Toyo AT.
Found a funny size 285/75/17 which is slightly wider than my 285/70/17 BFG KOs, but an inch taller, and recommended for my stock 17x7.5" rims. These are E-rated 3-plys with 3970 lbs. load capacity at 80 psi!
So also consider the Toyo A/T with some interesting sizes, with these three 18s recommended for your OEM rims.
Toyo A/Ts, I think the best fit for stock 18s are these. All are E-rated light truck tires, (LT), [be careful on the Toyo A/T, because they also sell P-rated passenger tires]:
1) A narrow, 35" 3-ply sidewall, with over 4000 pound capacity if aired up to 80psi. Note: due to the large diameter, this first size may cause issues with your Titan's torque converter not locking up correctly, and causing improper shift points, especially when towing:

LT285/75R18 129S E/10 300420 7.5-8.0-9.0 66 17 34.8 11.3 4080 80 2S+3P+2N 3P (35X11.5R18)
2) Probably the best fit, is this 33" with a 2-ply sidewall, and over 3600 lbs. capacity at 80 psi
LT275/70R18 125S E/10 300620 7.0-8.0-8.5 55 16 33.1 11.0 3640 80 2P+2S+2N 2P (33X11.0R18)
3) Another 2-ply sidewall, but E-rated, and also with over 3600 lbs. load capacity. Since this one's only 32.5" diameter, your Titan's overall gearing will be a little lower, which might be helpful when towing, (especially helpful if you don't have a Big Tow package).
