What is the recommended tire pressure for the RAM 2500?

The OEM cold tire pressure for the RAM 2500 is 55 PSI front and 65 PSI rear (cold). The factory tire size is 265/70R17. Always verify against your door-jamb sticker — your specific trim, wheel size, or load (e.g. fully loaded for a long trip) may shift the recommendation by 2–4 PSI.

What tyre pressure should I run for a RAM 2500?

For a RAM 2500 the manufacturer-recommended cold tyre pressure is 55 PSI front and 65 PSI rear (about 3.8 bar). This is the same number whether you say "tire" or "tyre".

Is 55 PSI correct for a RAM 2500?

Yes — 55 PSI is the OEM-recommended cold tire pressure for the RAM 2500 on its factory 265/70R17 tires. Adjust by +2 PSI for sport / motorway driving, +3 PSI when fully loaded, or −1 PSI when running a smaller wheel size for ride comfort.

What is the tire pressure in bar for a RAM 2500?

55 PSI converts to 3.79 bar. So the RAM 2500 runs 3.79 bar front and 4.48 bar rear at cold pressure.

Is the tire pressure the same on every RAM 2500 year?

For most RAM 2500 model years (2019–2024), the OEM cold tire pressure stays at 55/65 PSI on the factory 265/70R17. Some early-generation cars may differ — pick your exact year below to confirm. The biggest spec changes typically happen at a model generation reset (e.g. 2019 vs current).

Should I use the pressure on the tire's sidewall instead?

No. The number on a tire's sidewall is the maximum pressure the tire can hold — not the pressure your car needs. Always use the door-jamb sticker (or this database) for the OEM cold pressure that's tuned for your car's weight and suspension.

Should I check pressure cold or warm?

Always cold — meaning the car has been parked at least 3 hours, or driven less than 1 mile. Warm tires read 3–5 PSI higher than cold, so checking after a drive will fool you into under-inflating.

What category of vehicle is the RAM 2500?

The RAM 2500 is classified as a pickup vehicle, weighing about 2900 kg. Pressure recommendations are calibrated for that weight + axle load distribution — running significantly different pressures changes braking distance and wear pattern.

The RAM 2500 (2019–2024) is a pickup weighing approximately 2,900 kg with a 54% front weight bias. OEM cold tire pressure has remained constant at 55/65 PSI across all 6 model years. Front and rear pressures differ — typical for pickups where the axles carry uneven loads. OEM tire size is 265/70R17.

Adjustments

Weather, altitude, and load

Cold weather (below 0 °C): Tires lose roughly 1 PSI for every 10 °C drop. Going from a +20 °C summer day to a −10 °C winter morning, your 55 PSI tires read closer to 52 PSI — under-inflated. Compensate by inflating to 57/67 PSI when temperatures sit consistently below freezing.
Hot weather + long highway driving: Tires gain 4–6 PSI when hot from highway speeds in summer. Set cold pressure to the OEM number (55/65 PSI) — don't try to compensate by under-inflating cold. Always set pressure first thing in the morning, before the first drive.
High altitude (above 1500 m): Lower atmospheric pressure means a sealed tire reads ~1 PSI higher per 1000 m of elevation gain. Driving from sea level to a 2000 m ski resort, expect your gauge to read ~57 PSI for what was 55 PSI at sea level. This is benign — don't bleed it down.
Fully loaded (passengers + cargo): For a full house — passengers, luggage, towing — increase rear pressure by 2–4 PSI: 55/68 PSI is a safe target. The fronts stay the same since the steering axle load doesn't change much.

Common mistakes

Don't get this wrong

Reading the sidewall instead of the door jamb: The number stamped on the tire's sidewall is the maximum the tire can safely hold — usually 44–51 PSI. It's not what your RAM 2500 is tuned for. Use 55/65 PSI from the door-jamb spec.
Checking pressure when tires are warm: Tires gain 3–5 PSI after 5+ minutes of driving. If you check after a drive and see 59 PSI, you're actually running ~54 PSI cold — and you'll bleed it down to 55 PSI. Always measure after 3+ hours parked.
Using the spec from a different model year: Generation changes can shift the OEM number — different curb weight, different tire size, different load index. Pick your exact year above instead of trusting a forum post from a different generation.
Ignoring the rear when running loaded: Going on a long road trip with luggage + 4 passengers? Most manufacturers print a separate "max load" pressure on the door jamb (typically +3 PSI rear). For the RAM 2500, target around 55/68 PSI when fully loaded.
