2025 Silverado LT 2.5" motofab spacer in front with suspension max UCAs. 

1.5" suspension max rear block, also roadmaster active suspension which gave about another 1"-1.5" of lift. Peak suspension sway bar relocation brackets. 20x9 4Play OE Wheels cv65 +26mm offset. 285/65R20 Firestone Destination Xt tires.

Only rubs on driver's side at the front of the wheel liner just before full lock. I think it's due to the alignment, the shop couldn't get the caster on that side as good as the passenger side.

I know the K2 guys have one of these threads so I figured we should too. Think it’d be useful for others. Post pics of your setup! Make sure to add specs of the wheels/tires, spacers, suspension, rubb

2025 GMC Sierra 1500, Denali Ultimate.   Just changed out my factory wheels and tires for a much better look in my opinion. The new wheels are a OE knockoff of the 22" Escalade wheel.  Tires are 305/45/22    

 

Factory height,  absolutely no rubbing whatsoever.

Finally the time came for new tires. Had 42,000+ on the original BFG KO2s and they weren't bald, but getting pretty well worn so I decided it was time. I will say that I was impressed with the BFG KO2s they were probably the best AT tires I've ever owned and I've owned alot of different ones. This time I decided to try a mud tire.....these are Nitto Trail Grapplers M/T:

They are 305/55/R20 and I have them on Fuel Flame Blackout rims 20X10 -18 and with the new tires there were issues with rubbing the wheel wells. I anticipated this and made an appointment at a nearby body shop for immediately after the tire purchase and mounting. it was only really a few millimeters that made the difference but they not only trimmed plastic but metal as well. The mud guards were a problem and so this time they went away completely. I had bought the mud guard replacements from Sharptruck.com and I had them installed, although they also had to be modified quite a bit.

I do really like the look of these new Nitto tires, however I would say that if someone wants a quiet ride they are not for you because they are noisy on the highway. I have not had them in the rain yet so we'll see how that goes.

Hopefully someone can help me out here.....  got a 2020 sierra elevation does anyone know if I put a 3.5 inch rough country lift on it would I be able to run 35x12.50 with factory wheels?  Am I correct in assuming I'll have to have some spacers? I believe 2 inch would work...correct me if I wrong.

Depends what your factory wheels are. 17's, 18's or 20's? And how wide. Needs to be at least 8.5" wide for a 12.50 wide tire.

New truck, 26 RST 4x4 with LZ0. came with 265/65/18 on it and I was hoping to go with 275/70/18 that I had on my last truck. Previously I had a 2020 RST 2wd with a 3" front lift (top strut spacer and 2.5" rear block) and had no issues. Was wondering if I would need to lift again to prevent rubbing.

 

If I were to lift it, would I need to invest in the half shafts that the trail boss has?  if I recall, the trail boss uses longer half shafts for reliability.

Swapped out the factory RST 20s for these factory ZR2 18s. The difference in offset is perfect for a Silverado without fender flares.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
