5th Gen Ram 1500 Bolt Pattern & Tire Size Guide (2019+)

5th Gen Ram 1500 Fitment Guide: Bolt Pattern, Wheel & Tire Sizes
Updated June 2026 · Originally published May 2022Every 5th gen Ram 1500, meaning the 2019 and newer DT body, runs a 6-lug 6x139.7mm bolt pattern with a 77.8mm hub bore and M14x1.5 lugs torqued to 130 lb-ft. That includes the TRX and the new RHO. Stock coil-spring trucks take 33s clean. Slim 35s fit a leveled truck if you pick carefully, and a 3 inch lift makes 35s routine.
First, let's settle which truck you own, because Ram makes this genuinely confusing. The 5th gen is the DT body sold from 2019 to today, including the 2025 refresh. The tell: six lugs per wheel and the big RAM letters across the grille. If your truck has five lugs and the crosshair-style grille, it's a 4th gen or a Ram 1500 Classic (which Ram sold alongside this truck through 2024), and you want the 4th Gen Ram fitment guide instead. Count your lugs before you order anything. It's a thirty second check that saves a return label.
Good news once you've confirmed you're in the right place: the DT is one of the best-fitting trucks on the market. Big wells, wide stance, and factory sizing that already leans generous. Here's everything that clears at every height, with the setups we build most.

Max Tire Size by Suspension Setup
The question we get asked about this truck more than any other: what's the biggest tire that fits? Here's the straight answer for standard coil-spring trucks.
| Suspension | Clean Fit | Possible With Care |
|---|---|---|
| Stock | 33″ (33x12.5R20, 275/70R18) | Low-profile 22″ setups (305/45R22) |
| 2–2.5″ level | 33″ wide (33x12.5R20) | Slim 35s (35x11.5) with careful offset, possible trimming |
| 3″ lift | 35″ (35x12.5R20) | 35s on 22x10s, minor trimming |
| 4–6″ lift | 35″ on 12″-wide wheels | Show setups like 24x12 -44 on 35s |
Got Air Suspension? Read This First
The DT's optional four-corner air ride is fantastic to live with and mildly annoying to fit tires around. The truck self-levels, drops at highway speed for aero, and kneels for entry. A tire that clears at ride height can kiss the liner when the truck lowers itself, so air trucks should size one step more conservative than the chart above, or plan on minor trimming. Big lifts also need air-specific kits, since standard lift hardware assumes coil springs. The good news: our fitment team flags air-equipped trucks automatically when you shop by VIN, so what ships is what fits.
TRX and RHO: The Factory Monsters
The supercharged TRX (2021 to 2024) and its successor, the twin-turbo RHO (2025 and newer), share this generation's 6x139.7 pattern, so the wheel catalog crosses over. Everything else about them is wider and taller: flared fenders, more travel, and 35s from the factory. They don't need lift math to run big rubber, and most owners shop 18 inch wheels with high-clearance offsets, including beadlock-capable options. If that's your truck, call us and we'll build around its extra width from the start.
What Fits on Stock Suspension
No lift required for a serious stance on this truck. The most popular stock-height setup is 20x10 -18 with 33x12.5R20, a full 33 with real width, straight onto a factory-height truck.
What Fits With a Leveling Kit
A leveling kit kills the factory rake and buys front-end breathing room. The go-to combo is 20x10 -25 with 33x12.5R20, and it's the single most common package we ship for this truck.
| Style | Wheels | Tires |
|---|---|---|
| Small Wheel, Big Tire | 18x9 -12 | 33x12.5R18 |
| Daily Driver | 20x10 -25 | 33x12.5R20 |
| Big Wheel, Small Tire | 22x10 -24 | 33x12.5R22 |
What Fits With a 3-Inch Lift
Three inches is where 35s become a bolt-on instead of a project. The most popular setup: 20x10 -12 with 35x12.5R20.
| Style | Wheels | Tires |
|---|---|---|
| Small Wheel, Big Tire | 18x9 -12 | 33x12.5R18 |
| Daily Driver | 20x10 -12 | 35x12.5R20 |
| Big Wheel, Small Tire* | 22x10 -24 | 35x12.5R22 |
*May require minor trimming to fit.
What Fits With a 4 to 6-Inch Lift
Four to six inches turns the DT into a presence. Wheels past 10 inches wide clear without surgery, and the 22x12 deep-dish look comes into play. The build above says it all: 22x12 -44 with 35x12.5R22.
| Style | Wheels | Tires |
|---|---|---|
| Small Wheel, Big Tire | 18x9 -12 | 35x12.5R18 |
| Daily Driver | 22x12 -44 | 35x12.5R22 |
| Big Wheel, Small Tire* | 24x12 -44 | 35x12.5R24 |
*35s may need modifications on a 4″ or 5″ kit. The full 6″ is the no-drama route.
Why Buy the Package From SD Wheel

Frequently Asked Questions
What's the biggest tire on a stock 5th gen Ram 1500?
A 33 fits clean on standard coil-spring trucks, with 33x12.5R20 being the proven combo. Rebels clear a bit more thanks to their factory lift. For 35s, plan on at least a leveling kit for slim sizes or a 3 inch lift to run them comfortably.
Will 35s fit a leveled 5th gen Ram?
Slim 35s (like a 35x11.5) can work on a leveled truck with careful offset selection, and some builds need minor liner trimming. Full-width 35x12.5s on a level are pushing it. A 3 inch lift makes the whole conversation easy, which is why it's the popular path.
What's the bolt pattern on a 2019+ Ram 1500?
6x139.7mm (6x5.5 inches) with a 77.8mm hub bore, M14x1.5 lugs, torqued to 130 lb-ft. Same for every DT year from 2019 through the current trucks, plus the TRX and RHO.
Will my 4th gen Ram wheels fit?
No. The 4th gen and the Ram 1500 Classic use a 5-lug pattern and this truck uses 6. Nothing interchanges. If your truck has 5 lugs, head to the 4th Gen Ram fitment guide.
Did the 2025 refresh change any fitment?
No. The 2025 update brought new styling and the Hurricane engine family, but the bolt pattern, hub bore, lug hardware, and clearances carry over. Everything in this guide applies to the refreshed trucks, including the RHO with its factory 35s.
Fitment data verified June 2026. Sizes assume sensible wheel widths and coil-spring trucks unless noted. Air ride or TRX/RHO? Call us and we'll run your combo against the fitment database first.
