Recommended bar for a Chrysler Ram Van

Drivetrain: rear-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

European and UK handbooks usually quote bar. The Chrysler Ram Van catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Size estimates on this page include 215/50R17, 205/55R16 and 225/50R17 — interpolated from the catalogue midpoint, not a second factory sticker.

Chrysler Ram Van placard versus sidewall

The tyre-information placard on a Chrysler Ram Van sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Estimated pressure by tyre size (215/50R17 and others)

215/50R17 is the first planning size here. 225/50R17 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch

Load notes

Load moves the rear of a passenger car first. If the factory placard already has a “laden” column, use that instead of these sketches.

Condition	Front (est.)	Rear (est.)
Driver only	34 psi / 2.34 bar	34 psi / 2.34 bar
Full occupancy	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	37 psi / 2.55 bar

How to set the Ram Van

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Ram Van numbers in your head.
Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
If one corner is 4 psi down, hunt for a nail before you blame the weather.
Log date, ambient temperature and the four readings.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Ram Van.

Ambient	Gauge (front mid)	Bar	kPa	Note
−5 °C (hard frost)	31 psi	2.14 bar	214 kPa	Gauge reads low; do not overfill once warm
0 °C	32 psi	2.21 bar	221 kPa	Gauge reads low; do not overfill once warm
8 °C (UK winter morning)	33 psi	2.28 bar	228 kPa	Gauge reads low; do not overfill once warm
20 °C (set cold here)	34 psi	2.34 bar	234 kPa	Baseline
30 °C	36 psi	2.48 bar	248 kPa	Do not bleed a hot tyre
38 °C (heatwave tarmac)	37 psi	2.55 bar	255 kPa	Do not bleed a hot tyre

Chrysler notes

No special Chrysler exception: the Ram Van uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

Spare and inflator kit

A matching full-size spare on the Chrysler Ram Van usually follows the higher axle (often the rear, near 32-35 psi). A space-saver is commonly 60 psi / 4.1 bar — read that tyre’s own sidewall. An inflator kit is not a spare; check the sealant date.

A cheap gauge and a monthly habit will do more for this Ram Van than nitrogen upsells.

Questions about this Ram Van

Front versus rear on the Chrysler Ram Van?

This row is 32-35 F / 32-35 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.

How often should I check a Ram Van?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

Should I bleed pressure after a motorway run?

No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.

What is that in bar and kPa for the Ram Van?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

Is the sidewall number correct on a Chrysler Ram Van?

No. Sidewall PSI is a maximum. The Ram Van placard is the operating target, near 32-35/32-35 psi.
