Chevrolet S10 Tire Pressure (Recommended PSI)
TL;DR
S10 pressures vary a lot by generation, tire size and load; typical unladen figures sit near 34-35 PSI front, with rear pressure climbing noticeably (sometimes to 40-50 PSI) once the truck is loaded.
Why there is no single PSI number for the S10
The Chevrolet S10 has been built in Latin America across several generations (1995-2011, 2012-2016, and 2017-present), each offered with different tire sizes (235/75R15, 245/70R16, 265/60R18 and others) and both 4x2 and 4x4 drivetrains. Pickup trucks also commonly specify a higher rear pressure for loaded conditions than for an empty bed. Because of this, a single pressure figure cannot correctly describe every S10 on the road.
What we could verify
Cross-checking several Brazilian tire-calibration references (owner-submitted placard data cross-referenced across sources) turned up the figures below. Treat these as a starting point for your specific configuration, not a substitute for your own placard.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 1st gen (1995-2011) | 4x4 2.8 Diesel, 235/75R15 | 35 unladen (45 loaded) | 30 unladen (50 loaded) |
| 2nd gen (2012-2016) | LT, 245/70R16 | 34 unladen (38 loaded) | 34 unladen (40 loaded) |
| 3rd gen (2017-present) | 2.8 trim, 265/60R18 | 35 unladen (35 loaded) | 35 unladen (40 loaded) |
Reading it correctly
Note the pattern: front pressure usually stays close to the unladen figure even when the truck is loaded, while rear pressure often increases by several PSI once cargo goes in the bed. Some early 4x4 diesel configurations show front pressure actually higher than rear when unladen, which is the opposite of what many drivers assume - another reason to check your own placard rather than copy a number from another S10.
Where to find your exact figure
- The driver-side door jamb placard (or sometimes the fuel filler door) - this is the manufacturer's figure for your exact tire size and trim.
- Your owner's manual, usually in the tires and wheels or vehicle load section.
- The tire sidewall shows the maximum pressure the tire can hold, not the recommended running pressure - do not use that number for daily driving.
- If you tow or carry heavy loads regularly, Chevrolet's towing/loading guide for your model year gives the adjusted (usually higher rear) pressure.
Bottom line
Use the table above only as a rough regional reference. Always confirm the number for your own S10 generation, tire size and load condition on the door-jamb placard before adjusting your tires.
Summary
| Market covered | Brazil / Latin America Chevrolet S10 pickup |
|---|---|
| 1st gen (1995-2011) 4x4 2.8 Diesel, 235/75R15 | Front 35 / Rear 30 PSI unladen |

Frequently asked questions
What is the correct tire pressure for my Chevrolet S10?
It depends on your generation, tire size and whether the bed is loaded. Data we could verify shows unladen figures generally between 30 and 35 PSI front and rear, with rear pressure often rising to 38-50 PSI when loaded. Check your driver-door placard for the number that matches your exact tire size.
Is the pressure printed on the tire sidewall the one I should use?
No. The sidewall number is the tire's maximum cold inflation pressure (a safety limit for the tire itself), not Chevrolet's recommended running pressure for your vehicle. Always use the door-jamb placard or owner's manual figure instead.
Should rear tire pressure be higher than front on the S10?
Often yes, especially when the bed is loaded - several documented S10 configurations run 5-15 PSI higher in the rear when carrying cargo. Some early 4x4 diesel variants even show higher front than rear pressure unladen, so this is not universal; check your own placard.
Why do different websites list different PSI numbers for the same S10?
Because the S10 was sold with multiple tire sizes (15, 16 and 18 inch wheels) across three generations, and because many online tables mix unladen and loaded figures. A number that is correct for a 2013 LT on 245/70R16 tires will not necessarily apply to a 2019 model on 265/60R18 tires.
