Mazda Mazda3 Tire Pressure (Recommended PSI)
TL;DR
2019-2025 Mazda3: 36/36 PSI cold for normal loads (both 16 inch and 18 inch wheels); full load raises the rear. 2014-2018 Mazda3: sources vary between 33 and 36 PSI - check your placard.
Where the real number lives
Mazda prints the factory-recommended cold tire pressure on a placard inside the driver's door jamb (or on the B-pillar edge of the door frame), not as a single number that applies to every Mazda3 ever built. That placard lists pressure by tire size and by load condition (normal load vs. full load), and it is the only figure guaranteed correct for your exact car. The owner's manual repeats the same table.
What we verified
For the current-generation Mazda3 sedan (roughly 2019-2025), Mazda's published owner's manual specifies 36 PSI front and 36 PSI rear (cold) for normal loading (up to 3 occupants), on both the 205/60R16 and the 215/45R18 factory tire sizes. Under full load (5 occupants plus luggage) the manual raises pressures, with the rear commonly moving up to about 39-42 PSI depending on tire size and engine. Winter (M+S) tire sizes carry similar front figures with a somewhat higher rear figure under load.
Older generation - lower confidence
For the previous-generation Mazda3 sedan (2014-2018), independent tire-pressure aggregators report figures that are not fully consistent across model years - some list 33 PSI for certain years and 36 PSI for others. Because we could not corroborate a single trim-by-trim figure across multiple credible sources for that generation, we present it only as a range here. Do not treat 33 PSI as universal for that generation - check your own placard.
Data table
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 4th gen (2019-2025) sedan | 205/60R16, normal load | 36 | 36 |
| 4th gen (2019-2025) sedan | 205/60R16, full load | 38 | 42 |
| 4th gen (2019-2025) sedan | 215/45R18, normal load | 36 | 36 |
| 4th gen (2019-2025) sedan | 215/45R18, full load | 39 | 42 |
| 3rd gen (2014-2018) sedan | varies by year/tire size | 33-36 (unconfirmed per trim) | 33-36 (unconfirmed per trim) |
Why front and rear (and normal vs. full load) differ
Mazda specifies separate front and rear pressures, and separate normal-load and full-load pressures, because weight distribution shifts when the car is fully loaded with passengers and cargo. Running the full-load rear pressure when only one or two people are aboard makes the ride noticeably harsher and can wear the tire centers faster; running normal-load pressure while fully loaded can cause the tires to run hot.
How to read your placard
- Open the driver's door and look at the edge of the door frame (or the B-pillar) for a white or silver sticker.
- Match your actual tire size (printed on the tire sidewall) to the row on the placard.
- Use the normal-load column unless you are consistently carrying 4-5 people plus cargo, in which case use the full-load (or maximum-load) column.
- Set pressure cold, before driving or at least 3 hours after the car has been sitting.
Summary
| Placard location | Driver's door jamb / B-pillar edge |
|---|---|
| 2019-2025 sedan, normal load (205/60R16 or 215/45R18) | 36 PSI front / 36 PSI rear |
| 2019-2025 sedan, full load (205/60R16) | 38 PSI front / 42 PSI rear |
| 2019-2025 sedan, full load (215/45R18) | 39 PSI front / 42 PSI rear |
| 2014-2018 sedan (unconfirmed per trim) | Sources vary 33-36 PSI - check placard |
| Measurement condition | Cold, before driving or 3+ hours parked |
| Do not use | The maximum pressure molded on the tire sidewall |

Frequently asked questions
Is Mazda3 tire pressure the same for every trim and wheel size?
No. Mazda's own placards split pressure by tire size (for example 205/60R16 versus 215/45R18) and by load condition (normal load versus full load). On the current generation both common sizes share 36 PSI front and rear for normal load, but full-load figures differ and rise into the high 30s to low 40s at the rear. Always match your placard to your actual tire size, not to a number you saw for a different trim.
Where exactly is the tire placard on a Mazda3?
It is a sticker on the edge of the driver's door frame, visible when the door is open, sometimes described as being on the B-pillar. It lists cold tire pressure in both PSI and kPa for the original-equipment tire size(s), along with maximum vehicle capacity. This placard, not a generic online chart, is the correct source for your specific car.
Should I use the pressure on the tire sidewall instead of the door placard?
No. The number molded into the tire sidewall is the tire's maximum cold inflation pressure (a tire manufacturer safety limit), not Mazda's recommended pressure for ride, handling, and even wear. Always use the vehicle placard or owner's manual figure, which is typically lower than the sidewall maximum.
Why does my Mazda3 recommend a higher rear pressure when the car is full?
Mazda's full-load pressure table accounts for the added weight of extra passengers and cargo, which sits mostly over the rear axle in a sedan. Raising rear pressure under full load keeps the tire's contact patch and sidewall stiffness appropriate for the extra weight; using the normal-load figure while fully loaded can lead to overheating and reduced tire life on long trips.
