Anyone running 265/70R16 (~30.6")?

(Not a "will it fit?" thread).
Background: I'm running MarkMC's 2" lift and on the verge of buying wheel spacers. The TrailBlazer is getting promoted off of primary daily driver duty and my 245/70R16s (~29.5") need replaced (within a month most likely). Asking on GMTNation instead of OffroadTB for a reason; I like hitting some light trails and mud puddles on the weekends, but my TB is still an asphalt/gravel queen for now.

Stock tires look like goofy recessed little doughnuts and I want to fill the wheel wells better. There's a ton of pics out there of 265/75R16 (~31.6"), but they're too big for what I do IMO. I want a happy medium size and can't find any real good reference pics.
Request: Any pics of people running ~30.6" tires, bonus points for those with a lift and spacers?

Why not go with 17's? I'm sure you could find a set of wheels pretty cheap as these trucks are getting plentiful in yards. And you could upgrade to the bigger brakes.

Lines up nicely with the body IMO :cool:

The spacers were a must, I got these tires first, and could definitely feel them rubbing on the steering knuckle. Cut a nice lil groove in them on the short drive home, spacers were ordered later that day. I ground down the knuckle a touch for clearance as a stop gap.

I'm running 265/60/17 (30.6") with just Mark's 2" lift.

I've heard that it really depends on the brand of it clears without spacers. Too close for me to try without imo.

Yeah, I heard that too. When I got mine, I was originally going to stick with 265/65s like I had before. I could wedge a finger tip between the tire and steering knuckle with those. The website of the tire shop I went to said they had some in stock, but they didn't. They offered me the larger ones at the same price, for the inconvenience, so I took the gamble. The taller size also made me bottom out over the speed bumps in my neighborhood, so the lift was needed too. One of those mods I always wanted to do, but didn't really NEED to do it :raspberry:

I've thought about a second set of rims (5 is only about $200), but my goal is to just go with a slightly more aggressive tire that is still good on the road such as BFG KO2s so there's really no need to ever swap wheels based on where I'm driving. Plus the 16" rims will give me more rubber with my goal of ~30.5" tires. See more explanation below.

Like I may have said, I really like the look of the ~31.5" tires, but I'm already working with the 3.42 gear ratio. I want to go bigger just to shake the little doughnut look, but not 2" bigger.

I love how the wheels look with spacers. Makes it look a lot less like you're riding on stilts ready to rollover at any moment... That's why I want a set!

Any pics, especially from the side? @djthumper is the only other member I've found advertised as ever running this exact size, but I can only find good isometric views of his.

I am doing a 2" front 1.5" rear strut (EZ) lift and getting 1.25 wheel spacers (2004 LS). I want to run 267/75R16 on stock rims. I do NOT want to trim anything. Above it says there are tons of pics of this set up, so I assume it will work? where are these pics? I'm new and am very curious about clearance and how far past the wheel well these may stick out. I'd rather they be even and not beyond the wheel well. Anyone know, or better yet, have pics?

Is the EZ kit the outside strut death lift type? I thought EZ was the ebay one of them.

You do realize that you will need to grind the stock studs to use the 1.25 spacers, correct?

Pics are a simple search away. here or on offroadtb.com

They wont really stick out, but I dont think you can have no rub without trimming with 265/75/16. Prolly should do some searching and see what they cut to fit. I know offroadtb has a chart of what fits and what hits for combining lifts and tire sizes

OK, good info. Does "outside the strut, death lift" mean the kind that sits on top and compress the spring (2" steel with 3 studs to bolt up to the bracket?) Now I am worried. I am aware that the studs need grinding at 1.25, but I like the profile and think if cuts and torque are correct, it should be fine for a mall crawler.

Fronts look like these,

That is the DEATH LIFT . Do NOT use that trash please!

I would not be afraid of 1 or 1.25 spacers at all, just know you will need to grind a touch.

OK, that isn't the exact lift, but similar design. I just snagged that pic from google images to give the idea. Is there an acceptable suspension lift? I'd rather not mess with a body lift. GM Offroad claims 265/75R16 fit with a 2" lift and no trimming...but now I am wondering (last line in pic below).

Look at Supreme Suspension or the adjustable Bilstein 5100 struts for lift.

I trimmed with 265/70/17 and a 2.5 inch lift, but I also used mine offroad. May be ok for your use without trimming. I also never used stock wheels, so that prolly created some of clearance issues.

Awesome, now I just have to figure out what a safe lift would be. I have 200, 000 miles and running strong with minimal (zero visible) rust and I want to do something to this truck before it sails to the boneyard having spent it's whole life stock. Thanks for the advice.

Not sure I understand the physics behind this making it a better option, but OK, I'll go this way instead. Last question: Do you recommend flipping the control arms when doing this? I had seen it suggested once or twice. I have been following forms for a while, so I know just enough to be stupid and dangerous. I appreciate your time man, Thanks

The physics is you cant extend the overall strut length safely. You force the ball joint to be the downward travel stop and and that can cause failure. Also it has been shown to destroy the splined disco that costs more than a lift by about double. Also will cause the CV to bind at droop.

You should flip/swap control arms with any lift.
