2016 Silverado Z71

2.5 inch front/ 1 inch rear with bilsteins all around

OEM GMC A/T 20x9

33/12.50 Toyo M/T

 

Rubs pretty bad on turns at about 3/4 lock (pulling out of parking spots, etc.) - more forward than reverse....strange?

 

Rubbing is consistent on the UCA's on both sides (due to bulky stamped steel arms), and that seems to be the only point of contact.

 

Need recommendations from anyone running wheel spacers please! are the hubcentric ones with the studs the best option? what about reliability? Wheel spacers scare me, but love the look of my truck and as it sits and it took me forever to find these wheels at a good price so they are staying....

That looks awesome. Too bad it's rubbing bad. Would new control arms solve the problem?

For those of you running RTs on 17s what PSI are you running? My local place airs everything to 40ish so I'm at 42-45psi right now and want to air down to 35 truthfully but would that be too low for this tire?

Nobody can give your the correct answer as every vehicle will be different. I would personally air them down to where you want to be in your head and then chalk test. If you still have a full contact patch then you're good. Personally I never noticed a difference between 35 to 45 PSI. But I also had fox coilovers up front so those helped to I'm sure. And I'm also 27 so my bad feels no pain yet lol.

An exhaust and intake make a big difference. Also, as stated your calculation is off (for the worse) dive you changed tire sizes. I gained about 3 mpg with my Diablo tune, Borla ProXS and AEM filter. I haven't even changed over the MIT yet. I'm hoping to get a little more after I do that as well.

 

That being said, the days of 20 mpg around town are still over hahaha! I can get 18 at best. Usually 15. Highway maybe 21 at best... I used to be able to get mid 20's on the highway. I was disappointed but it just looks sooo much better and the rim protection offered by these Duratracs is a huge plus.

 

Your truck looks sick btw.

Did you just install one of the canned diablo tunes? Or a custom?

I just got my diablo tuner in yesterday and am currently messing around to find which tune I want.

Haven't gotten to drive it much yet though.

Lol i'm only 26, i don't have Fox' up front, just bilsteins. 45 was definitely noticeable.

 

Excuse my ignorance but what's the chalk test?

I did a canned tuned. I chose advanced 91+ tune. There's a thread on here with a link for the exploded menu online. It's not as good as it should be but it's better than the manual it comes with. Truck is light years different than stock and now my speedo/odometer is correct.

Nice! I will have to keep playing around with it then and see what I can get.

I can already feel a difference in the shifting, I need to correct my speedo as well and change the shifts. Excited to see how good it gets.

Thanks man, I appreciate it! It really is a shame that its that bad. Planned on a narrower tire, but came across these for 1k with stickers still on them so I couldn't pass it up. Now I'm here.....looking for information on wheel spacers......hah

The correct answer is to get narrower tires or rims with more negative offset. There is a sticky about spacers....BORLA seems to be the best, but run them at your own risk. They work great, until they don't.

Test fit a tire on the front to check clearance. Has about a finger width clearance at the fender liner so should be fine without pulling the liner back.

What brand steps do you have on your truck. I like those.

DeeZee NXT. I added filler pieces on the back to fill the gap between the boards and rocker panels.

    • I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!
    • I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be. 
    • I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!
    • I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify. 
    • I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
