Last updated on 5 min read

The bolt pattern on a 2008 Dodge Ram 2500 is 8×165.1 mm (8×6.5 inches), which means it works with most stock and aftermarket wheels made for this setup.

What lug pattern is a Dodge Ram 2500?

All Ram 2500 models use an 8×6.5-inch (8×165.1 mm) bolt pattern, no matter the year or trim.

This has been the go-to pattern for Dodge Ram 2500s since the '90s—and even earlier in some cases. Funny enough, it matches what Ford and Chevy use on their heavy-duty trucks, so swapping wheels between brands is doable with the right adapters.

Is 8×170 the same as 8×6 5?

No, 8×6.5 and 8×170 aren’t the same—they’re completely different bolt circle sizes.

See, 8×6.5 inches converts to 165.1 mm, while 8×170 mm is a bigger pattern used on newer Ford Super Duties. Both have eight lugs, but you can’t swap wheels between them without adapters. Always double-check the exact measurement before buying anything.

Is 8×6 5 the same as 8×165 1?

Yep, 8×6.5 inches is exactly the same as 8×165.1 mm—just two ways to write the same thing.

One’s in inches, the other in millimeters. The number after the "×" always shows the diameter of the circle the lug studs make. This pattern’s been around forever in Dodge, Ford, and Chevy heavy trucks built from the '60s through 2026.

What’s the bolt pattern on a 3/4 ton dodge?

A 3/4-ton Dodge Ram 2500 uses an 8×6.5-inch (8×165.1 mm) bolt pattern as standard.

That includes every 3/4-ton Ram 2500, whether it’s a Hemi, Cummins diesel, or something older. The bolt pattern’s stayed the same for decades, though factory offsets and center bores can change depending on the year and trim.

Can you fit 8×170 on 8×6 5?

Nope, you can’t bolt 8×170 wheels straight onto an 8×6.5 hub without adapters.

To mount 8×170 wheels on an 8×6.5 truck, you’ll need an adapter that fits the Ram’s hub on one side (6.5 inches) and the Ford wheel on the other (170 mm). Always go for hub-centric adapters and re-torque the lug nuts after 50–100 miles of driving.

What bolt pattern is 8×170?

The 8×170 bolt pattern shows up on 1999 and newer Ford F-250 and F-350 Super Duty trucks as standard.

It’s got eight lugs spaced on a 170 mm circle. You’ll also find it on some commercial rigs and lifted trucks. Doesn’t match the Dodge Ram pattern unless you use adapters.

What size are stock Dodge 2500 wheels?

Most stock Dodge Ram 2500 wheels measure 17×8.0 inches with a 44 mm offset, though that can vary by year and trim.

Factory sizes range from 17×7.5 to 20×12, depending on options like the Heavy Service Package or Off-Road Group. With stock wheels, you can usually fit up to a 35-inch tire with a 12.5-inch width—if the fenders clear it, of course.

What lug pattern is a 2004 Dodge Ram 2500?

That goes for the 5.7L Hemi, 6.7L Cummins diesel, or even the older 5.9L Cummins. This pattern’s been locked in for over 30 years on Ram 2500s.

What will 8×6 5 wheels fit?

An 8×6.5-inch bolt pattern fits Dodge Ram 2500/3500 (1946–present), Ford F-250/F-350 (1955–1998), Chevy/GMC 2500/3500 (1967–2011), and the Hummer H2.

It’s one of the most common heavy-duty truck patterns in North America. If you’re buying aftermarket wheels, always check the center bore, offset, and load rating to make sure they’ll fit right and perform safely.

Is Ford and Dodge 8 lug the same?

No, Ford and Dodge 8-lug patterns aren’t the same unless both measure 8×6.5 inches.

Dodge Rams from the '60s onward use 8×6.5, as do Chevy/GMC trucks from that era. Ford’s older 8-lug pattern (pre-1999) is also 8×6.5, but their newer Super Duties switched to 8×170. Always confirm the exact measurement—not just the lug count.

What is 8×180 bolt pattern?

The 8×180 bolt pattern has eight studs on a 180 mm diameter circle, and you’ll usually find it on Chevy and GMC 2500HD/3500HD trucks.

Do Chevy and Dodge have the same bolt pattern?

Yes, the 3/4-ton Chevy Silverado 2500HD and Dodge Ram 2500 share the same 8×6.5-inch bolt pattern.

This matchup covers most 3/4-ton and 1-ton models from the late '90s through 2026. Still, center bore and offset differences might mean you need adapters or tweaks for a perfect fit.

What bolt pattern is a 2017 Ram 2500?

The 2017 Ram 2500 uses an 8×165.1 mm (8×6.5-inch) bolt pattern, same as every other Ram 2500.

That includes both the 6.4L Hemi and 6.7L Cummins diesel versions. The pattern hasn’t changed since the early 2000s, so wheels are easy to find.

Are wheel adapters Safe?

Wheel adapters aren’t safe for high-speed, heavy-duty, or performance use unless they’re high-quality, aircraft-grade aluminum units made for the job

Cheap adapters can crack, loosen, or vibrate at highway speeds. The NHTSA even warns that bad adapters can lead to wheels flying off. Stick to SAE- or TÜV-rated adapters, check torque after 50 miles, and avoid aggressive driving. Never use adapters on trucks meant for towing or hauling heavy loads—it’s just not worth the risk.
