Ok.. My stock tires are 265/75R16 Pro AT M and 26.5 x 0.75 = 18.55 / 2.54 =7.3 sidewall x 2 = 14.6 + 16 = 30.6" tires, right?
So changing to a 33" tire would be 2.4" bigger and add 1.2" overall lift?
35" tires would be 4.4" bigger and add 2.2" of lift over what I have now? And thats full diff lift..
And i would need a 3" body lift anyway to fit 35s, and so my floorboards would be lifted 5.2" higher than they are now?
Thats pretty high. It would help for rivers for sure.. Not sure if my wife would be happy climbing up or not, i'll have to ask her.. Might have to get her a little chrome step or something.
If I'm in water up to bottom of the body, do i have to worry about anything getting wet? People need breather tubes for their diffs too? And is it only the distributor that I have to worry about getting wet in the engine? And whats the height of that?
I have this 5-in-1 I got at Harbor Freight thats got an Air Compressor with PSI Gauge, a Jumper Battery, AC Power Inverter, USB & DC power, and Work Lights.. Is that enough?
I've never heard of a built in air system.. Does it take up much space? What all is involved? It sounds super cool..
265/75/16 =
265 mm x 0.75 = 198.75 mm so the sidewalls are ~ 199 mm or ~ 7.82"
So, 15.6" of sidewall + 16" of rim = 31.6" of total tire diameter, or, nominally, 32".
So, a 33" tire (Which might BE 33", or, 32.6", etc...) would be about
one inch taller in DIAMETER....and add ~ 1/2" in CLEARANCE.
A 35" tire would be ~ 3" taller in diameter, and add ~ 1.5" in clearance.

So....with 35's...you'd be ~ 1.5" higher.
With the 3" BL you'd add to fit them, your BODY would be a total of ~ 4.5" higher.
Your diffs and a few other parts under there have breather tubes....not to breath per se, but because they get hot in use, and, the air in them expands...and the tube lets the hot air out instead of making them pressurize/blow seals, etc.
If you go into (cold) water, the hot air is chilled, and, shrinks, so the diffs, etc, now need to suck in make up air, or be under vacuum/suck in water, etc...and, then, the same tubes let in make up air.
...so you have tubes, but, you make sure they're on and not torn, etc...and sometimes extend them up higher just in case....as in water, that's when you ARE sucking in air as the diffs are chilled...and you want AIR to be what DOES get sucked in.
Your distributor is on top of the engine....so your hood's awash if that's wet...and some Si spray etc, and even that being wet is fine.
Your air intake (IN-Take...) is where you don't want the water to be as high as.
That's about at headlight height at your wheel well...so if your tires are no longer visible, its time to pay attention.
This is why people get a snorkel...even if NOT for forging deep water, sometimes there's an under water rut, etc...and the ~ hub deep tame water suddenly drops one side down to the headlight....and its NOW deep water, etc.
