2015 Ram Chassis Cab wheels & tires
The spec sheet doesn't list tire sizes for this model year; here is what the owner's manual says.
- Cold tire pressure
- Not a single number: the owner's manual refers to the tire and loading placard (driver's side B-pillar or rear edge of the driver's door), which lists the pressures for your exact tire size and load.
- Spare
- Manual covers compact, full-size and tire-service-kit setups depending on equipment; the sheet does not say which applies.
- Lug nut torque
- 130 ft-lb (176 N·m) (Cone type), M14 x 1.50 thread, 22 mm socket
- Pressure monitor
- A tire pressure monitoring system warns when a tire is low.
Sizes and pressures vary by trim, wheel package and load: check the placard on your vehicle and the tire sidewall. Sizes from the manufacturer's specification sheet (2015 Ram 3500 Chassis Cab Specifications, 2015 Ram 4500/5500 Chassis Cab Specifications). Pressure and spare notes from the owner's manual.
2015 Ram Chassis Cab maintenance schedule
The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.
A dot means the service is due at that mileage or after that many years, whichever comes first.
Additional Inspections
- Inspect front suspension, tie rod ends, and replace if necessary
- Inspect the front and rear axle surfacesIf gear oil leakage is suspected, check the fluid level. If using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid.

Read for lake-effect country
Reading the 2015 Chassis Cab data for Great Lakes roads
We read the 2015 Chassis Cab owner data, service schedule and spec sheets with Kentucky driving in mind: frozen starts, salted highways, cratered streets and hills. These are the figures worth acting on.
The oil grade on a January morning
The fluids table calls for SAE 5W-20 or 5W-30 by temperature (5.7L), SAE 0W-40 (6.4L) and SAE 15W-40 or 5W-40 by temperature (6.7L Cummins turbo diesel) at 7 qt (5.7L), 7 qt (6.4L) and 12 qt (6.7L Cummins turbo diesel), with synthetic oil in the specification. Synthetic stock copes with both ends of this region's weather, from a subzero start in the Upper Peninsula to a loaded summer climb in the Smokies. Match the exact specification on the filler cap, not just the viscosity.
Cranking power for a lake-effect morning
A Chassis Cab left at a lake cottage or in a pole barn for weeks slowly drains its battery, and a cold snap then finds it with nothing to spare. A plug-in maintainer for stored vehicles is cheap insurance in the Great Lakes states.
Traction for snowbelt hills and hollows
This model year offers four-wheel drive. In Kentucky, the payoff comes in the first hour of a storm, before plows reach side streets, and on boat ramps slick with algae where a two-wheel-drive tow vehicle can spin. Keep the system's limits in mind on ice: driven wheels add grip for going, not for stopping or turning.
Trailer duty in the schedule
Regular towing puts the 2015 Ram Chassis Cab on the schedule's trailer rows: axle fluid, automatic transmission fluid and transfer case fluid service, first at 20,000 miles. A summer of hauling a boat to Lake Cumberland, Norris Lake or a Lake Michigan launch counts. The Great Lakes are fresh water, so a trailer's real corrosion threat here is winter road salt, not the ramp.
Tank size for hill country
The 2015 Ram Chassis Cab holds 22 to 52 gallons of fuel. Once you leave the interstate in West Virginia or eastern Kentucky, mountain routes can run a long way between stations, and the climbs burn more fuel than flat miles do. Fill up before heading into the hills.
Gravel hollow roads and the air filter
The schedule asks for more frequent air-filter attention in dusty conditions, beyond the normal replacement every 30,000 miles. Gravel roads up Appalachian hollows and coal-haul routes in West Virginia and eastern Kentucky qualify, so inspect the filter at each oil change if they are part of your week.
Data behind these notes: owner's manual capacities, the Mopar service schedule and factory spec sheets. Regional advice is general, written for drivers from Kentucky to Michigan.
2015 Ram Chassis Cab questions
How much oil does the 2015 Ram Chassis Cab take?
With a filter change: 5.7L engine, SAE 5W-20, 7 qt / 6.6 L; 5.7L engine, SAE 5W-30 (3500/4500/5500 trucks over 14,000 lb / 6,350 kg GCWR), 7 qt / 6.6 L; 6.4L engine, SAE 0W-40 synthetic, 7 qt / 6.6 L; and 6.7L Cummins turbo diesel, 12 qt / 11.4 L. Capacities are from the owner's manual; check the dipstick or oil-life display after filling.
What kind of oil does the 2015 Ram Chassis Cab use?
5.7L engine: SAE 5W-20, API certified (MS-6395); 5.7L engine, trucks over 14,000 lb (6,350 kg) GCWR: SAE 5W-30, API certified (MS-6395); 6.4L engine: SAE 0W-40 full synthetic, API SN (MS-12633); 5.7L/6.4L engines: Mopar engine oil filter; 6.7L Cummins turbo diesel, ambient above 0°F (-18°C): SAE 15W-40, API CJ-4 required (Cummins CES 20081 oils also acceptable) (MS-10902); 6.7L Cummins turbo diesel, ambient below 0°F (-18°C): SAE 5W-40 synthetic, API CJ-4 required (MS-10902); and 6.7L Cummins turbo diesel: Mopar engine oil filter.
When is the first scheduled maintenance on the 2015 Ram Chassis Cab?
At 20,000 miles or 2 years: inspect front suspension, tie rod ends, and replace if necessary; inspect the front and rear axle surfaces. if gear oil leakage is suspected, check the fluid level. if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid; inspect the brake linings, parking brake function. Oil changes in between follow the oil-change indicator.
Where can I find the 2015 Ram Chassis Cab owner's manual?
The manufacturer publishes it free on Mopar.com as a PDF (linked in the manuals section above), along with quick guides, radio manuals and the warranty booklet.
What MPG does the 2015 Ram Chassis Cab get?
The EPA doesn't publish a fuel-economy rating for the Chassis Cab: heavy-duty pickups, chassis cabs and full-size vans above 8,500 pounds gross vehicle weight are exempt from fuel-economy labeling, so there is no official MPG figure to quote.
Does the 2015 Ram Chassis Cab have recalls?
NHTSA lists 8 safety recall campaigns for the 2015 Ram Chassis Cab. The most recent: Wheels: lugs/nuts/bolts/studs (May 2021), Electrical system: wiring (May 2018), and Equipment (December 2017). NHTSA's data was last fetched November 8, 2026. Recalls are listed by model year, so a given vehicle may or may not be covered: enter its VIN at nhtsa.gov/recalls or ask a dealer to see which are open.
What are the most common safety complaints about the 2015 Ram Chassis Cab?
Owners have filed 20 complaints about the 2015 Ram Chassis Cab with NHTSA. The components named most often are engine (6), electrical system (5), and power train (4). 1 complaint involved a crash and 3 complaints a fire. Complaints are reports from owners that NHTSA does not verify, so treat them as a signal to look into, not a finding.
Specifications come from the manufacturer's spec comparison and its media-site specification sheets; maintenance schedules, fluids and publications come from Mopar's owner site and owner's manuals. Equipment and ratings vary by configuration; check the owner's manual or a dealer for a specific vehicle.
