2014-2018 Silverado 1500 Bolt Pattern & Wheel Size Guide
June 1, 2026
What Wheels Fit a 2014–2018 Silverado 1500?
Updated June 2026 · Originally published May 2022Every 2014–2018 Silverado 1500 runs a 6x139.7mm bolt pattern (you'll also see it written as 6x5.5″, same thing) with a 78.1mm hub bore and M14x1.5 lug nuts torqued to about 140 lb-ft. Same specs on the GMC Sierra 1500 from those years. Stock suspension handles up to 33s if you pick your offset right. For 35s, plan on a 4 inch lift or taller.
The 2014–2018 Silverado hit that sweet spot where the truck is cheap enough to buy, tough enough to keep, and popular enough that the aftermarket makes everything for it. Whether yours is a work truck earning its keep or a weekend project headed for 22s, this guide covers the specs, what clears at each suspension height, and the exact setups we mount and ship most often.
One thing before we start: everything here applies to the GMC Sierra 1500 from the same years too. Same frame, same hubs, same fitment. And if you're looking at a 2019 Silverado LD or Sierra 1500 Limited on the used lot, that's this body style with a newer badge, so this guide covers those as well.

Max Tire Size by Suspension Setup
The question every Silverado owner eventually asks: how big can I go before things start rubbing? Here's the honest answer.
| Suspension | Clean Fit | Possible With Care |
|---|---|---|
| Stock | 32″ (275/55R20, 275/65R18) | 33″ with the right offset |
| 2–2.5″ level | 33″ (275/60R20, 285/65R18) | 33x12.5 on wider wheels |
| 3″ lift | 33″ wide (33x12.5R20) | 34″ with minor trimming |
| 4–6″ lift | 35″ (35x12.5R20) | 35s on 12″-wide wheels, minor trimming under 6″ |
What Fits on Stock Suspension
No lift, no problem. The go-to stock-height move is a 20x9 +20 wheel with 275/55R20 tires. That's factory diameter with a little more width and a lower offset, which pushes the stance out just enough to look intentional without touching anything.
| Style | Wheels | Tires |
|---|---|---|
| Small Wheel, Big Tire | 18x9 +18 | 275/65R18 |
| Daily Driver | 20x9 +20 | 275/55R20 |
| Big Wheel, Small Tire | We don't recommend going past 20″ on stock suspension | |
A proven pairing here: Fuel Assault 20x9 +20 with a Nitto Terra Grappler G2. We build that exact package all the time, mounted and balanced before it leaves the warehouse.
What Fits With a Leveling Kit
A leveling kit is the best money you can spend on this truck. It cancels the factory nose-down rake, installs in an afternoon, and opens the front wheel wells up for a taller tire. The classic combo is 20x9 0 with 275/60R20, a true 33-inch-tall tire that fills the wells the way the factory should have.
What Fits With a 3-Inch Lift
Three inches of lift means wider wheels and wider rubber without the rubbing homework. Far and away the most popular setup here is 20x10 -18 with 33x12.5R20. The extra width and negative offset give the truck that planted, filled-out look.
| Style | Wheels | Tires |
|---|---|---|
| Small Wheel, Big Tire | 18x9 -12 | 33x12.5R18 |
| Daily Driver | 20x10 -18 | 33x12.5R20 |
| Big Wheel, Small Tire* | 22x10 -18 | 33x12.5R22 |
*May need minor trimming to fit.
What Fits With a 4 to 6-Inch Lift
This is where the truck stops asking permission. Wheels over 10 inches wide clear without major surgery, and 35s become the normal choice instead of the ambitious one. A proven crowd favorite: 20x12 -44 with 305/55R20.
| Style | Wheels | Tires |
|---|---|---|
| Small Wheel, Big Tire | 18x9 -12 | 35x12.5R18 |
| Daily Driver | 20x12 -44 | 305/55R20 |
| Big Wheel, Small Tire* | 22x12 -44 | 35x12.5R22 |
*35s may need modifications to clear on a 4″ or 5″ kit. The full 6″ is the no-questions option.

Frequently Asked Questions
What's the bolt pattern on a 2014-2018 Silverado 1500?
6x139.7mm, which is the same measurement as 6x5.5 inches. It applies to every year in the generation (2014, 2015, 2016, 2017, and 2018), every trim, and the matching GMC Sierra 1500. The hub bore is 78.1mm and the lugs are M14x1.5.
Will 2019+ Silverado wheels fit my 2014-2018?
Yes. GM kept the 6x139.7 pattern and 78.1mm bore on the newer trucks, so the wheels bolt right up. Double-check the offset though, since factory offsets differ slightly between generations and that changes how the wheel sits.
What's the biggest tire on a stock 2014-2018 Silverado?
A 32-inch tire like a 275/55R20 fits clean. You can squeeze a 33 in with careful offset selection, but you're flirting with rubbing at full lock. A simple 2-inch leveling kit makes 33s a non-event, which is exactly why it's the most popular first mod on this truck.
Does this guide apply to the GMC Sierra?
Completely. The 2014-2018 Sierra 1500 shares its frame, hubs, and fitment with the Silverado, so every spec and size recommendation here carries over. Same for the 2019 Silverado LD and Sierra Limited, which are this body style sold one extra year.
Do 2WD and 4WD trucks fit the same sizes?
Wheel specs are identical. The 4WD trucks have front-end components that meet a big tire slightly sooner at full lock, so treat our recommendations as the 4WD-safe numbers. If you're 2WD, you've got a little extra breathing room.
