Can I fit 285 75 r18 tires on 3/2 level +18 offset without bmc?

Okay so I've been reading for awhile now and i havent seen a definite yes yet. info says:
3″ Lift Kit
With a 3″ lift kit, the options continue to get better. However, the wider the tire, the greater the likelihood of trimming.
Max tire sizes are:

• 18″ rims: 285/75 R18 – 4/10ths wider and 2.8″ taller than factory.

Now it sounds like front will clear just fine but the rear with only 2" block lift, I will have .8" in height difference. Is that enough to make the rear rub?

https://www.tacomaworld.com/tirecalc?tires=295-70r18-285-75r18

according to this, the widely used 295 70 r18 is .57" shorter in diameter. Think that is enough to require me to get a bmc? 34.26" vs 34.83".

 

In my limited experience, I don’t know, but it seems that if the fronts are good, the rears will be more than fine. Use the offset calculator. I don’t know what your original offset is. For me, the rears were not in question, but I kept it all even with the fenders. This is a diff truck, but stock was 17x7.5 wheels with 15mm offset. 265/65/17 tires. I raised the front to level and left the back alone. After a shit ton of math, I decided on 17X8.5 at 0 offset. That kept the backspace 2mm more room than stock, and the wheel stance was about a 1/2” farther out due to the reduced offset and another 1/2” due to the 1” wider wheel. Calculator showed it at 1.04” wider stance per side. I was going to go 265/70/17 tires, and knew they would fit easy. On a quick mental change at the shop, went 275/70/17. Knew that was only a .4” wider tire. The rears were no concern because the fronts would fit and I wasn’t running outside of the fenders. And my height was only a step up and not a big one. If you are going wide stance, maybe the rears hit on up travel, but the fronts seem to me would have more issues. I found a site I can’t remember that had real installs, specs, models/years and what was needed as far as chop or boy. I didn’t rely on that, just where I started, the online calculators and searching this forum, google. I can’t rub my tires if I wanted to. Best of luck.

 

I have Bilstein 6112 on top setting and Total Chaos UCAs. I have run Toyo MT 285/75R18, Toyo AT 285/75R18 and Cooper AT3 XLT in 285/75R18 all with no issues and no BMC. I now run 37x12.5R17 Cooper AT3 XLT on the same lift with a BMC and am also fine unless I obviously bottom the truck out while at full left or right. It will rub then.
