# How do I check and maintain proper tire pressure on my 2021 Tesla Model 3?

Use the touchscreen to check tire pressure on your 2021 Tesla Model 3. Tap **Controls > Service > Tire Pressure**. It shows PSI for each tire. Tesla recommends **42 PSI cold** for optimal range and safety. Check when tires are cold, meaning after the car sits for 3+ hours.

## Quick Steps to Check Pressure
1. Park the car on a level spot.
2. Wait 3 hours or drive less than 1 mile.
3. Open the touchscreen menu: Controls > Service > Tire Pressure.
4. Note the PSI for all four tires.

Here's what you need to know:
- **Cold pressure**: 42 PSI front and rear.
- **Low pressure alert**: Below 39 PSI triggers a warning.
- **High pressure risk**: Over 45 PSI wears tires unevenly.

| Tire Position | Recommended PSI (Cold) | Check When |
|---|---|---|
| Front Left | 42 | Monthly |
| Front Right | 42 | Before trips |
| Rear Left | 42 | Cold tires |
| Rear Right | 42 |:::::: |

## How to Maintain Proper Pressure
Keep tires at 42 PSI to save energy and extend tire life. Proper pressure boosts range by up to 10%, says Tesla's 2021 Model 3 manual (Source: Tesla Service Manual, 2021). Low pressure cuts range 5-10% and raises crash risk, per NHTSA data (Source: NHTSA Tire Safety Report, 2025).

**Action steps**:
- Check monthly or before road trips.
- Use a gas station air pump or portable compressor.
- Unscrew valve cap. Press chuck onto valve stem. Add air until 42 PSI.
- Recheck after driving 1 mile, as tires warm up.

In Newton, MA (02466), visit Mobil on Washington St or Tesla Service Center in Dedham. They offer free air checks. AAA reports proper inflation prevents 11% of tire failures (Source: AAA Tire Maintenance Study, 2025)," says the AAA Research Team.

Winter drops pressure 1 PSI per 10°F. Add 2-3 PSI in cold MA weather. Tesla's system alerts you, but verify manually. Rotate tires every 6,250 miles per Tesla schedule.

Sidekick tracks your 2021 Model 3 maintenance reminders. It flags tire checks based on your drive data from 1,200+ Tesla owners. Owners who maintain tires save $250/year on replacements, per Sidekick data (N=850 verified EVs, Q1 2026).

## Common Mistakes to Avoid
- Skip hot tire checks. They read 4-6 PSI high.
- Ignore rear tires. They often run lowest.
- Forget seasonal changes. Adjust twice a year.

Follow these steps, and your Model 3 stays efficient. Tesla tires last 30,000-40,000 miles with good care. Questions? Check your owner's app.
