Test Procedure
- Pre-test: Confirm tire is a 215/55R17 specification. Deflate tire to 25 psi baseline pressure before each run.
- Unit preparation: Connect the S5 inflator to the tire valve. Ensure the unit is fully charged or connected to the appropriate power source as per standard operating conditions.
- Start inflation: Begin inflation from 25 psi and start timing simultaneously.
- Stop timing: Stop the timer the moment the unit’s pressure gauge or auto-shutoff confirms 35 psi has been reached.
- Record: Log the elapsed time in min:sec format for the completed run.
- Repeat: Deflate tire back to 25 psi and repeat steps 3–5 for a total of 10 runs per unit.
- Switch unit: Repeat the full 10-run sequence with the second sample unit (2#).
- Post-test: Compile all 20 recorded times and review for consistency and outliers.
- Acceptance criterion: All runs must complete successfully; recorded times should demonstrate consistent repeatability across runs.
Test Data & Results
The table below contains all 20 recorded inflation runs across both sample units. The tire specification is 215/55R17 and the pressure range is 25–35 psi for every run.
| Unit | Run No. | Time (min:sec) | Unit | Run No. | Time (min:sec) |
|---|---|---|---|---|---|
| 1# | 1 | 01:17 | 2# | 1 | 01:06 |
| 1# | 2 | 01:18 | 2# | 2 | 01:15 |
| 1# | 3 | 01:26 | 2# | 3 | 01:15 |
| 1# | 4 | 01:19 | 2# | 4 | 01:23 |
| 1# | 5 | 01:19 | 2# | 5 | 01:13 |
| 1# | 6 | 01:03 | 2# | 6 | 01:17 |
| 1# | 7 | 01:12 | 2# | 7 | 01:27 |
| 1# | 8 | 01:17 | 2# | 8 | 01:26 |
| 1# | 9 | 01:18 | 2# | 9 | 01:11 |
| 1# | 10 | 01:23 | 2# | 10 | 01:09 |
Observations: Unit 1# completed all 10 runs with times ranging from 01:03 to 01:26. Unit 2# completed all 10 runs with times ranging from 01:06 to 01:27. Both units show a typical spread of approximately 20–24 seconds across their run sets, indicating stable motor and pump performance under repeated load cycles. No run failures or anomalous stalls were recorded.

Frequently Asked Questions
How long does the ETENWOLF S5 take to inflate a 215/55R17 tire from 25 to 35 psi?
In testing, the ETENWOLF S5 inflated a 215/55R17 tire from 25 psi to 35 psi in approximately 01:03 to 01:27 (minutes:seconds) across 20 consecutive runs on two sample units, with most runs completing between 01:09 and 01:23.
Is the ETENWOLF S5 inflation performance consistent across repeated uses?
Yes. Both test units completed 10 runs each without failure. The total spread across all 20 runs was approximately 24 seconds (01:03 to 01:27), which reflects stable motor and pump performance under repeated load conditions.
What tire size was used in the S5 inflation efficiency test?
The test used a 215/55R17 passenger car tire, a common mid-size fitment, making the results broadly representative of typical sedan and crossover applications.
What pressure delta was tested for the ETENWOLF S5?
The test measured the time required to raise tire pressure by 10 psi — specifically from 25 psi to 35 psi — which reflects a realistic top-up scenario for a slightly underinflated passenger tire.
