Re: Wheel and tire size info needed!!
Dick Cepek and Mickey Thompson both make that size, but I'm not so sure they would fit.
I'm running 285/75/18 Toyo AT's with a 4-inch lift that hits the sway bar on the right side when holding full left steering lock. Both my cams on the right are maxed out to give 1.2 degrees caster, so I can't pull the wheel back any farther.
The rubbing is only on the right side, is very slight, and only when holding full left lock. I'm going to see if it's possible to shift the sway bar mount since there is 1/4 inch clearance on the left, but I doubt it's adjustable. Anyway, I knew this was an issue when I did my test fit and decided to go with the tires anyway.
The 305/70/18 is the same height as my 285/75/18 but a lot wider. My guess is they would rub more, but until you do a test fit you really won't know for sure.
BTW the 305/65/18 BFG AT I used to run fit fine and only needed the usual skid plate bend.

Front Susp: Stock coilovers, 4" lift ( http://www.tundrasolutions.com/forum...6-4-inch-lift/), just swapped extra spacers for Bilstein 5100s on lowest setting, wheel well height still 41.5."
Rear Susp: ProComp ES3000 #326510 (2.25" taller than stock), 1.25" blocks plus PRG mini-pack ( http://www.tundrasolutions.com/forum...and-new-truck/) gives 2.25" total lift, parking brake cable bracket spacers, wheel well height 43."
Front diff and rear ds drop; trailer hitch electrical harness tucked up above bumper.
After 20K miles swapped 305/65/18 BFG AT for 285/75/18 Toyo AT, still on stock 18x8x60 offset TRD wheels, about 1/8" clearance to sway bar. Like the extra height but miss the width. Next time either 305/70/18 or 35x12.50/18.
Added 5th 285/75/18 Toyo AT as spare. Foam pad above spare to help with bed bounce.
Bed Bounce: Stiffer E-tires are worse than stock P-metric; biggest improvement from PRG mini-pack, slight improvement from shocks and foam pad above spare. Still a stiff ride but tolerable now.
Best things about this truck: 5.7 and transmission, interior size and comfort, very quiet at high speed.
Worst things about this truck: bed bounce, no VSC in 4wd, mileage sucks above 70.
