I can't help with the trimming question but I can answer the fuel mileage question. You will gain between 10 and 15 lbs a tire in going up that 1 inch. You are going to lose some fuel economy just turning the extra weight, now factor in the increased rolling resistance of the wider tire, you will notice the difference in economy.

No trimming necessary. None even if you move up to 35

Finally installed everything this past weekend! Toytec 3/1 leveling kit with bilstein 5100 series rear shocks, 35×12.50 ko2's on 18×9 fuel hostages with +20 offset. Also added color matched bushwacker extend-a-fender flares.
Last pic is next to a stock crewmax
Looks great.

Finally joined after months of rummaging through every post and topic relating to the subject of leveling with 35's for my own 2017 tundra. not too sure if this will be the same for the older gen (2013 and below) or if its 100% accurate it maybe like 99%. Please correct me if I'm wrong because I wont really know until I pull the trigger. Hope this helps those who are doing the same thing.

To sum it all up it is essentially this:

At least a 3/1 level or equivalent will fit 35's on a 9" wide wheel (not sure about 10"+ wide don't see much of those in the forum)

Minimum 5.75" of Backspacing on the Rim, No Trimming of mounts or wells, just removing mud flaps. less backspace = more chopping or higher lift.

5.75" Back Spacing Translates to +20 offset and up on aftermarket wheels. At +18 offset you will rub a bit at full lock since its at 5.71" of back spacing. smaller offset = more chopping or Higher lift

Stock Wheels are +60 offset so if you're planning to add wheel spacers to your after market wheels it will reduce your offset. just convert your spacer inches into millimeters and subtract from the +60 or whatever wheel offset and that will essentially be your new offset if you have wheel spacers.

less than +60 offset will move the tire outside of wheel well +18, +20, +25 will be outside of wheel well at about an inch or less i think at about +35 it will be flush with the top of the wheel well.

Tire sizes:

18" Wheels

33" Tire Diameter
275/70R18 = 33.2x10.8R18
285/70R18 = 33.7x11.2R18
295/65R18 = 33.1x11.6R18
305/65R18 = 33.6x12R18
325/60R18 = 33.4x12.8R18
33X11.5R18
33X12.5R18
33X13R18
33X13.5R18

34" Tire Diameter
285/75R18 = 34.8x11.2R18
295/70R18 = 34.3X11.6R18
305/70R18 = 34.8x12R18
325/65R18 = 34.6x12.8R18
34X12.5R18

35" Tire Diameter
315/70R18 = 35.4x12.4R18
35X12.5R18
35X13R18
35X13.5R18
35X14.5R18

20" Wheels

33" Tire Diameter
275/60R20 = 33x10.8R20
285/60R20 = 33.5x11.2R20
295/60R20 = 33.9X11.6R20
305/55R20 = 33.2x12R20
33X12R20
33X12.5R20
33X13.5R20

34" Tire Diameter
275/65R20 = 34.1x10.8R20
285/65R20 = 34.6x11.2R20
305/60R20 = 34.4x12R20
315/60R20 = 34.9x12.4R20
355/50R20 = 34X14R20

35" Tire Diameter
295/65R20 = 35.1X11.6R20
325/60R20 = 35.4x12.8R20
35X11.5R20
35X12.5R20
35X13R20
35X13.5R20
35X14.5R20

Calculation if missing a tire size:

example:
325/60R20 = Tire width in millimeters (325) / Sidewall Ratio in % (60) Rim Diameter in inches (20)

1 mm = .03937 inches

325 x .03937 = 12.79 inches - Tire Width
.60 x 12.79 = 7.67 inches - Sidewall Height
20 + (7.67*2) = 35.35 - Overall Tire Height

That is essentially the culmination of my research on leveling with 35's. This was exactly the kind of information I was looking for when I was researching. Now go out there and save money cause this sh#$% is expensive haha.
Tak,

That is fantastic. I appreciate your work.

Hey guys I could really use some help here, I’m driving myself crazy! Here’s my setup: 2014 Crewmax SR5 TRD 3/2 Readylift Leveling Kit Fuel 20x9 with +20 offset
I currently have 295/60/20 Nitto Trail Grapplers and they basically shredded the passenger side front plastic liner behind the bumper (mostly at full lock) I’m looking to fill up some of the open space in the wheel well and I don’t want to do any other mods or chopping. Any tire size suggestions? Please help!
