2014-2018 Chevy Silverado Fitment Guide: Bolt Pattern & Tire Sizes
August 2, 2026
2014-2018 Chevrolet Silverado Fitment Guide
Quick Answer
Every 2014-2018 Chevy Silverado 1500 runs a 6x139.7 mm (6x5.5") bolt pattern with a 78.1 mm hub bore and M14x1.5 lug nuts torqued to 140 lb-ft. Stock tire sizes run from 255/70R17 to 285/45R22 depending on trim, a 275/55R20 (about 32") is the stock suspension sweet spot, and a simple leveling kit opens the door to true 33s.
So you own, or just picked up, a 2014-2018 Chevrolet Silverado. Now comes the fun part: making it stand out from the other three in the parking lot. This guide covers every number that matters: the exact bolt pattern and lug specs for each year, what came stock on every trim, the biggest tires you can run at each suspension height, and the wheel and tire combos already proven on real customer trucks.
Silverado Wheel Specs by Year (2014-2018)
GM changed nothing across this generation, so whether you drive a 2014, 2015, or 2018, these are your numbers:
| Year | Bolt Pattern | Hub Bore | Lug Nuts | Torque |
|---|---|---|---|---|
| 2014 Silverado 1500 | 6x139.7 (6x5.5") | 78.1 mm | M14x1.5 | 140 lb-ft |
| 2015 Silverado 1500 | 6x139.7 (6x5.5") | 78.1 mm | M14x1.5 | 140 lb-ft |
| 2016 Silverado 1500 | 6x139.7 (6x5.5") | 78.1 mm | M14x1.5 | 140 lb-ft |
| 2017 Silverado 1500 | 6x139.7 (6x5.5") | 78.1 mm | M14x1.5 | 140 lb-ft |
| 2018 Silverado 1500 | 6x139.7 (6x5.5") | 78.1 mm | M14x1.5 | 140 lb-ft |
The same specs apply to the GMC Sierra 1500 of these years. Chevy 1500 and Sierra 1500 wheels swap freely, which doubles your options when hunting a specific look.
Silverado Bolt Pattern by Generation
Here's the part that makes Silverado ownership easy: GM has used one bolt pattern on every 1500 since 1999. Wheels move between generations without adapters, as long as you match tire diameter and offset to your suspension.
| Generation | Bolt Pattern | Notes |
|---|---|---|
| 1999-2006 Silverado 1500 | 6x139.7 (6x5.5") | Same pattern, older body styles |
| 2007-2013 Silverado 1500 | 6x139.7 (6x5.5") | See our 2008-2013 Silverado guide |
| 2014-2018 Silverado 1500 | 6x139.7 (6x5.5") | This guide |
| 2019-2026 Silverado 1500 | 6x139.7 (6x5.5") | Wheels interchange with your truck both ways |
| Silverado 2500HD / 3500 | 8-lug: 8x165.1 to 2010, 8x180 from 2011 | Different animal entirely; those wheels will not fit a 1500 |
Got a 2019? Check the body first. GM sold a carryover truck called the 2019 Silverado 1500 LD that wears this 2014-2018 body style. If your 2019 looks like the trucks on this page, this is your guide. And when shopping used wheels, remember the 2500HD and 3500 are 8-lug: they will not bolt to your 1500.
Stock Wheels & Tires for the 2014-2018 Silverado
What your truck wore from the factory depends on trim, not year. This generation was also the first Silverado offered with factory 22s. Every stock size lands between roughly 31 and 32 inches tall:
| Factory Wheel | Stock Tire Size | Overall Diameter | Typical Trims |
|---|---|---|---|
| 17x8 (+24) | 255/70R17 | 31.1" | Work Truck (WT) / LS |
| 18x8.5 | 265/65R18 | 31.6" | LT / Z71 |
| 20x9 | 275/55R20 | 31.9" | LTZ / High Country |
| 22x9 (accessory) | 285/45R22 | 32.1" | Optional dealer accessory package |
Factory offsets sit in the mid +20s, which keeps the wheels tucked inside the fenders. That's why the most popular aftermarket setups on this truck drop toward zero or negative offset: same suspension, completely different stance. Our wheel offset guide explains how to pick the right number for the look you want.
What Fits at Every Suspension Height
These setups come from real customer trucks: combinations we know clear because they're already on the road. Find your suspension, pick your lane.

Stock Suspension Fitment
The most common setup for this generation on stock suspension is a set of 20x9 +24 wheels with 275/55R20 tires. Same tire size the LTZ wore from the factory, but the lower offset pushes the wheel out to the fender line and completely changes the truck's stance.
- Small wheel, big tire: 17x9 +0 wheels with 265/70R17 tires
- Daily driver: 20x9 +24 wheels with 275/55R20 tires
- Big wheel: We don't recommend running wheels larger than 20 inches on stock suspension.

Leveling Kit Fitment
A leveling kit is the most popular first upgrade on these trucks, and on this platform it earns its keep: it unlocks true 33s. The go-to package is 20x9 +1 wheels with 33x12.5R20 tires.
- Small wheel, big tire: 17x8.5 +0 wheels with 285/70R17 tires
- Daily driver: 20x9 +1 wheels with 33x12.5R20 tires
- Big wheel, small tire: 22x9 +24 wheels with 33x12.5R22 tires (may require minor plastic trimming)

3-Inch Lift Fitment
A 3 inch lift buys you wider, more aggressive setups without rubbing worries. The most popular combo at this height is 20x10 -19 wheels with 33x12.5R20 tires.
- Small wheel, big tire: 17x8.5 +0 wheels with 33x12.5R17 tires
- Daily driver: 20x10 -19 wheels with 33x12.5R20 tires
- Big wheel, small tire: 22x10 -18 wheels with 33x12.5R22 tires (may require trimming)

4-6 Inch Lift Fitment
A 4-6 inch lift changes the entire personality of this truck. Wheels over 10 inches wide clear without major modifications, 35s become daily-drivable, and the parking lot officially belongs to you. A proven favorite: 20x9 +1 wheels with 35x12.5R20 tires.
- Small wheel, big tire: 17x9 -12 wheels with 35x12.5R17 tires
- Daily driver: 20x9 +1 wheels with 35x12.5R20 tires
- Big wheel, small tire: 24x12 -44 wheels with 35x12.5R24 tires (6 inch lift and plastic trimming required)
Max Tire Size at Every Height
The question behind every question: how big can I go? Here's the honest answer for a 2014-2018 Silverado, height by height:
| Suspension | Comfortable Max | Notes |
|---|---|---|
| Stock | 275/55R20 (~32") | No rubbing, no trimming. The safe ceiling |
| Leveling kit | 33x12.5 (33") | True 33s clear with the level installed; widest 22s may need minor trimming |
| 3" lift | 33x12.5 (33") | Adds room for wide, negative offset wheels under the 33s |
| 4-6" lift | 35x12.5 (35") | 35s daily-drivable; 24x12 monsters need 6" and trimming |

What is the bolt pattern on a 2014-2018 Chevy Silverado 1500?
Every 2014-2018 Silverado 1500 uses a 6x139.7 mm (6x5.5 inch) bolt pattern with a 78.1 mm hub bore and M14x1.5 lug nuts torqued to 140 lb-ft. This is identical for every year and trim in the generation, including 2014 and 2018 models, and the GMC Sierra 1500 shares the same specs.
Is the lug pattern the same on every 2014-2018 Silverado?
Yes. The 2014, 2015, 2016, 2017, and 2018 Silverado 1500 all share the exact same 6x139.7 (6x5.5 inch) lug pattern, so a wheel that fits one year fits them all. GM has used this pattern on every Silverado 1500 since 1999, which means wheels also interchange across generations.
What size tires come stock on a 2014-2018 Silverado?
Depending on trim, a 2014-2018 Silverado 1500 came stock with 255/70R17, 265/65R18, or 275/55R20 tires, plus 285/45R22 on the optional 22 inch accessory wheels. Every factory size lands between roughly 31 and 32 inches tall, including on 2014, 2015, and 2018 models.
What is the best tire size for a 2014-2018 Silverado?
The best tire size depends on your suspension. On stock suspension, 275/55R20 is the proven sweet spot. With a leveling kit, step up to 33x12.5R20. A 3 inch lift keeps 33s while adding room for wider wheels, and a 4-6 inch lift comfortably runs 35x12.5 tires.
What is the biggest tire that fits a stock 2014-2018 Silverado?
The biggest tire that fits a stock 2014-2018 Silverado 1500 without rubbing is about 32 inches, and 275/55R20 is the size we recommend for a worry-free daily driver. If you want true 33s, plan on at least a leveling kit; they clear comfortably from there.
Do 2019 and newer Silverado wheels fit a 2014-2018 Silverado?
Yes. The 2019-2026 Silverado 1500 kept the same 6x139.7 bolt pattern and 78.1 mm hub bore, so wheels swap between the generations in both directions. Just match the tire diameter to your suspension height and double-check offset, since factory offsets differ slightly between generations.
