Hey guys, new to the site. Been lurking for a couple of weeks just reading and trying to soak up as much knowledge as I can. Thus far though I haven't been able to find the exact answer to my question. I just bought a 2010 Silverado Ext. cab Z-71 brand new last week from a dealer I do some work for. A friend of mine just took a Truxxx 2.5" leveling kit with the 1" lift rear blocks off of his truck. The kit was only on his truck for about 10k miles. He just upgraded to a 6" lift. I think I'm going to put his Truxxx kit on my truck as this will be my daily driver.

 

I've just about decided I'm going with the Ballistic Jester 20 x 9 in chrome finish. This wheel comes in 3 different offsets, +12, 0, and -12. I think I'm gonna go with the Cooper Zeon LTZ. I'm just wondering what offset wheel I can go with and what size tire would be the most I could go with without significant rubbing. I don't mind trimming a little plastic but would like to avoid cutting metal. Here are the sizes I looked at- 275-60 and 305 -50. I know the 275 is a little taller tire but I really like the width of the 305. I don't mind the wheel sticking out a hair, maybe .5". Hope this isn't a repost of someone else's dilemma but I wasn't able to find the exact answer to my question through searching the posts. Thanks for your help.

Welcome to the site. I'm running 8.5" wheel with 5.5" of backspacing as well as the cooper zeon's. Awesome tire btw.

 

Anyways, with a 9" wide wheel, I think it would be the perfect offset. :uhoh:

What size tire do you think? Also help me understand the principle of the offset. Doesn't a negative offset push the wheels further out while a positive offset pulls the wheels in closer to the truck?

You're probably right Blackout. I just really like the way the more negative offset looks. I'm sure that's what you're running right? Wonder if I could get away with the 0 offset. It has a 5" backspace while the -12 has 4.5".

Yes sir, my wheels have a -25 offset and are 10" wide. I was a little nervous about it when I ordered them, but I love the way they look, so I understand where you're coming from. You could definately run the 0 offset wheels but you should probably opt to run the 275/60's. :P

That's what I'm kinda thinking too. I like a little depth to the wheel. Just looks sharper IMO. So you think no rubbing issues with the 0 offset and 275/60's?

With a 2.5" leveling kit you should be ok. You may need to use a zip tie or two on the plastic liner but I doubt it.

Thanks for all your help man! And BTW, love your truck! I'll post up some pics after I get the lift installed. Maybe a few months before the new shoes.

Well, I hate to keep coming back to this but I'm just wondering what I would have to do if I wanted to run a -12 offset. I keep looking at wheels and I just like the depth of the wheel better. I know it will undoubtedly stick out more but that look is just killer to me. So I'm just wondering what I would have to do lift wise to run that offset or will the Truxxx 2.5" leveling kit permit me to run that offset? And if the Truxxx kit will work, what size tire could I run?

You can run that kit no problem with those wheels. As far as tires I think I would stick with a 275/60 or maybe a 285/55.

What would a 18x9 with a -11 offset and 4.5 backspacing look like? I am lost on all this backspacing and offset stuff too. Would they stick out alot farther than stock?

They would stick out a good 2+ inches more.

So -12 with 275/60/20 is probably what I will go with. Let me ask you this thought Blackout, should I be concerned about ball joint stress with the 2.5" lift? I know I've read a few of you're posts on this site that were a little negative about that much lift with a spacer. I think the Truxxx kit is adjustable. There are 3 shims per side on this lift. I just wonder if I went down to 2.25" I could still run the setup on wheels and tires I just mentioned and save some stress or does it really matter. Just for the record, my truck will see the offroad very rarely. Really just bought the 4WD for pulling duckboat up a ramp and the occasional trip to the camp. One of those insurance things. :cheers:

 

Oh yeah, just to be sure 275/60/20 with -12 offset and 2.5" level = no rubbing?

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.
