Im also debating between -10mm or -38mm offset wheels. From what I read, 38mm can work with these conditions on 285/70/17
1. Remove mud flap
2. Aggressive BMC
3. Angle cut the black rocker cover
But if you want 295/70/17
1. Same as above
2. Pinch weld mod
There’s a few vids on YouTube regarding the pinch weld mod.

I would count on it.
more than likely

Tire size isn't really what dictates the necessity for a BMC.... it's the wheel offset generally.
For SCS wheels, anything with a -38mm offset will need it, no question about it. I have SCS wheels with a -38mm offset - it required a BMC.
I ran 285/70/17's on 0mm offset, with NO lift and I was fine after trimming the front bumper quite a bit. Hopefully that sheds some light regarding what you need to do.

-38 is borderline bro dozer specs lol. JK. You can look at the possibility of aftermarket UCAs, finding an alignment tech (easier said than done) that will move your caster forward 3 or 4 degrees, then trimming your front bumper cover such as they did in this link.

There are no guarantees and it's always trial and error in these situations.
The other side of the coin is you could have a dozen testimonials from people who have done it with "nooooo problem bro".
The main thing is to put what ever OCD you might have aside, and be ready to cut some plastic.
I went with the SCS F5 that has the minimal offset, no BMC, and had a 285 AT cooper work well.
Switched to the same size Cooper MT and it rubs in certain situations now.
At this point in the mod game I don't give AF anymore and just roll with it.
An aftermarket offroad bumper also helps a lot with forward clearance FWIW. But that may be a mod your not willing to get into yet.
Good Luck!

Im running the SCS Ray10 w/ -38 offset. You will more then likely need a BMC (I already had one before going to the -38). The reason I went with the -38 is to keep the tires off off the UCA's since I'm running 35x12.5.
Your lift is irrelevant, offset is your challenge here. You will need a BMC because of basic geometry of pushing the wheel away from the well. Having an ORP, your front fender will not be trimmed from port like a TRDP, so you'll need to do that as well (trim/push, takes 20 minutes). The BMC is a bit more difficult, but if you have a cutter and a welder, it shouldn't take more than a couple hours of driveway time to knock out.
I'm about to do the same next week, F5s (-38) w/STT Pros at 295/70.

Here’s a comparison of stock body mount vs bmc. You can see how chopping gives you that much more space. The bmc picture also has a cut out on the flaps.

These are not my pics. It’s a local guy who got bmc and also has -38mm wheels w/ 285/70/17. He claims no rubbing at full lock reverse. Only the stock bm is mine.

Ok, so here is my feedback on -38s and 295/70/17 on my '18 TRDP
Swapped out my TRDP wheels and 285s and moved up in tire size, here is what I've experienced so far
Mods:
1" level spacer up front
Removed mudflap
Fender Liner Mod
Normal driving is a relatively no issue, the only rubbing I have is on the front bumper, just need to trim it 1/2" and it'll be fine. No rub on the BMC at full lock (no articulation), but it just barely hits the rocker valance at a very specific point.
Again, this was just driving around town and normal driving conditions.

If you dont offroad you should be fine especially with 275s. I'm running f5's -38 with 295s and I had to do alot of mods. Still rub when I offroad . City driving is ok for the most part.
