Tires are the most underrated safety feature on your car. They're your only contact with the road — four palm-sized patches of rubber that determine whether you stop, turn, and grip in every condition. Yet most drivers don't think about their tires until something goes wrong.
This year-round guide covers everything you need to know about tire care — from monthly checks to seasonal swaps.
Monthly: Check Pressure and Inspect
Tire pressure changes roughly 1 PSI for every 10°F change in temperature. A tire that was perfect in September can be dangerously low by December.
- Check pressure when tires are cold (before driving or after sitting 3+ hours)
- Use the PSI specified on the driver's door jamb sticker — not the number on the tire sidewall
- Don't forget the spare tire
- Visually inspect for nails, cuts, bulges, or uneven wear
Under-inflation causes edge wear, increases blowout risk, and hurts fuel economy. Over-inflation causes center wear and reduces traction.
Every 5,000–7,500 Miles: Rotate
Tire rotation moves each tire to a different position to ensure even wear. Front tires wear faster because they handle steering and bear more braking forces. Common rotation patterns:
- Front-wheel drive: Front tires move straight back; rear tires cross to the front
- Rear/all-wheel drive: Rear tires move straight forward; front tires cross to the back
- If tires are directional: Front and rear swap on the same side only
Regular rotation can extend tire life by 20–30%. Most tire shops include free rotations with purchase.
Spring: Post-Winter Assessment
After months of cold temperatures, salt, and potholes:
- Inspect all tires for pothole damage — look for bulges in the sidewall
- Check alignment — winter potholes frequently knock alignment out of spec
- If you're running winter tires, swap them off when temperatures consistently stay above 45°F (7°C). Winter rubber compounds soften in warm weather, reducing grip and wearing faster.
- Clean salt and brake dust from wheels and tire surfaces
Summer: Heat Management
Hot pavement accelerates tire wear and increases blowout risk:
- Reduce speed on extremely hot days — road surface temps can exceed 150°F
- Check pressure more frequently, as heat causes pressure to rise
- Never deflate hot tires to the "correct" PSI — they'll be under-inflated when cool
- If you notice any vibration, have tires balanced immediately
Fall: Winter Preparation
- Measure tread depth. Replace tires that are below 4/32" if you'll be driving in rain or snow. The legal minimum is 2/32", but traction drops significantly before that point.
- Consider dedicated winter tires if you live in an area with regular snow or ice. The performance difference versus all-seasons is dramatic — shorter stopping distances and better cornering grip.
- Store off-season tires in a cool, dry place, upright or stacked horizontally. Keep them away from direct sunlight and heat sources.
Winter: Maximum Vigilance
- Check pressure weekly — cold air causes rapid pressure drops
- Clear ice and packed snow from tire surfaces before driving
- In icy conditions, reduce speed significantly and increase following distance to 8–10 seconds
- If you have all-season tires in moderate winter conditions, ensure they have at least 5/32" of tread for adequate snow traction
When to Replace
Replace your tires when:
- Tread depth reaches 2/32" (the legal minimum) or 4/32" for wet/snow driving
- You see sidewall bulges or cracks
- The tire is more than 6 years old (check the DOT date code on the sidewall)
- You notice vibration that persists after balancing
- Wear is uneven despite regular rotation — this often indicates alignment or suspension issues
For SWIFT Hosts
Your tires directly affect renter safety and your reviews. Keep a visual tread depth check in your between-booking routine, maintain proper pressure, and don't delay replacement. A blowout during a rental is the worst possible experience for everyone involved.
Proper tire care keeps your car safe, your renters happy, and your operating costs low. Host your well-maintained vehicle on SWIFT.
