Jeep Grand Cherokee Tire Pressure (Recommended PSI)
TL;DR
There is no single universal PSI for the Grand Cherokee - front is usually 33 PSI across trims, but rear ranges from 33 to 36 PSI depending on trim and tire size, so check your placard.
Why there is no single number
The Jeep Grand Cherokee has been sold across several generations (WK, 2005-2010; WK2, 2011-2021; WL, 2022-present), and within each generation Jeep specifies different cold tire pressures depending on trim level and the tire/wheel size fitted at the factory. A page that lists one PSI figure for the whole model line is oversimplifying - some trims run 33 PSI front and rear, while others (mostly 20-inch-wheel Limited, Overland, Summit, Altitude and Upland trims) run 33 PSI front but 36 PSI rear.
What we could verify
For the WK generation (2005-2010), the Laredo and Limited trims on P235/65R17 and P245/65R17 tires are documented at 33 PSI front and rear. For the WK2 generation (2011-2021), Laredo and Laredo E trims on 17 and 18-inch tires run 33/33, while Limited, Overland, Summit, Altitude, High Altitude, Limited X and Upland trims on 265/50R20 tires run 33 front and 36 rear (the Limited on 265/60R18 is listed at 36/36). The SRT and Trackhawk performance trims on 295/45R20 run 33/33. Data describing the current WL generation (2022 and later) largely mirrors this same pattern in the source we reviewed, but because that generation's listing was not independently cross-checked against a second source, treat it as indicative only and confirm on your own placard.
Where to find your exact number
The only fully reliable source for your specific vehicle is the tire and loading information placard on the driver's door jamb (open the driver's door and look at the edge of the door frame or the pillar). This placard is set for your car's exact trim, tire size, and load rating as built - it overrides any generic chart, including this one. Your owner's manual repeats the same figures and also lists a separate, usually higher, pressure for full-load or towing conditions.
Practical tips
- Check pressure cold, before driving or at least three hours after the vehicle has been parked.
- Recheck monthly and before long trips - tires lose roughly 1 PSI per 10 degrees Fahrenheit drop in temperature.
- If your Grand Cherokee has a spare, check its placard-listed pressure separately - it is often higher than the road tires.
- Never inflate to the number stamped on the tire's sidewall - that is the tire's maximum rating, not the vehicle's recommended pressure.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| WK (2005-2010) | Laredo / Limited, P235/65R17 or P245/65R17 | 33 | 33 |
| WK2 (2011-2021) | Laredo / Laredo E, 17-18 inch tires | 33 | 33 |
| WK2 (2011-2021) | Limited, 265/60R18 | 36 | 36 |
| WK2 (2011-2021) | Limited / Overland / Summit / Altitude / Upland, 265/50R20 | 33 | 36 |
| WK2 (2011-2021) | SRT / Trackhawk, 295/45R20 | 33 | 33 |
| WL (2022-present) | All trims (single-source data, verify on placard) | 33 | 33-36 |
Summary
| Front PSI (most trims) | 33 |
|---|---|
| Rear PSI (base trims, 17-18in wheels) | 33 |
| Rear PSI (Limited/Overland/Summit, 20in wheels) | 36 |
| SRT / Trackhawk (295/45R20) | 33 / 33 |

Frequently asked questions
Is 33 PSI correct for every Grand Cherokee?
Only for front tires on most trims. Rear pressure varies - many base trims on 17 or 18-inch wheels run 33 PSI rear too, but several higher trims on 20-inch wheels (Limited, Overland, Summit, Altitude, Upland) specify 36 PSI rear. Check your driver's door placard to be certain.
Where exactly is the tire pressure placard located?
Open the driver's door fully and look at the door jamb (the vertical edge of the body the door closes against) or the lower door pillar. The sticker lists front and rear cold PSI, tire size, and the maximum load.
Should I use the pressure printed on the tire sidewall instead?
No. The sidewall number is the tire's maximum cold inflation pressure, not the vehicle manufacturer's recommended pressure. Always use the door placard or owner's manual figure, which balances ride, handling, and tire wear for that specific vehicle.
Does towing change the recommended tire pressure?
Yes, on many Grand Cherokee trims the owner's manual lists a higher pressure for maximum load or trailer towing than for normal driving. Check the towing or loading section of your owner's manual in addition to the door placard.
