2003 Gr. Cherokee Tire PMS overactive with smaller sidewall tires

Depending on the manufacturer and type of tire, the tire pressure spec's will be different, The labeling imprinted on the sidewall of the tire will specify the recommended tire pressure. Most average tire pressures used for highway tires is 32 P.S.I.

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

Try the glove box door, if there's nothing there, 32 psi is generally considered a good default pressure. All tires have a maximum value written on their sidewall and if your truck is heavily loaded you may want to increase the pressure but don't exceed a value that is 5 psi lower than the maximum on the tire. This allows a little headroom for heat expansion.

the tire pressure should be on a sticker by the drivers door, if you can't find it there is a max pressure on the sidewall of the tires, set them close to that

If you do not have the owners manul then the tire manufaturers recomended pressure will be on the sidewall of the tire colest to the rim.Will be very small and give you load pounds@__ psi cold.32-44PSI but may be higher.

I would advise you to leave both sides with 235 45 17 this tire size would provide you with better handling and improved comfort also tires wil be more protected of suffering damage in the sidewalls caused by bumps and potholes just remember to keep them inflated at 38 +/- 2 psi.

well you can find the max tire pressure on the tire it self. it should say psi xx

On the driver door opening decal the recommened tire pressures if not there its in the rear door opening and it's in the owers manuel under tires. The kind of whells or options need to be obserbed as the differt options may have different recomended pressures and the rear may have a different than the fornt if all the stickers are gone and the owers manuel is too 32 PSI is a safe best bet some 50 or 45 series tires need as much as 45PSI never put more pressure in the tire than what it says on the sidewall but the maximun pressure is safe but might not give the best ride quailty

Normally anywhere from 32 psi to 40 psi. To know exactly what your vehicle calls for look inside the door panel. There will be a label there that shows load and pressure ratings for all of your tires. If you do not see the label look on the tire itself. There will be a psi rating on the sidewall of the tire.
