Most vehicles need new tires when tread depth drops to 3/32 of an inch. For all-terrain tires like those on off-road trims, you should also replace them every 6 years, even if tread looks fine.
Key Replacement Triggers
Replace tires when any of these apply:
- Tread depth at 3/32 inch or lower - Use the penny test (insert penny into tread; if you see Lincoln's head, tread is too worn)
- Age reaches 6 years - Check the DOT code on your sidewall; last four digits show manufacture week and year
- Visible damage - Cracks, bulges, cuts, or punctures mean immediate replacement
- Uneven wear patterns - Indicates alignment or pressure issues
- Mileage between 40,000 to 60,000 miles - Typical lifespan for all-terrain tires
- Reduced traction or handling - If your truck feels less grippy, especially off-road, tires are wearing out
Off-Road Specific Considerations
If you frequently drive off-road, inspect tires more often. Rough terrain accelerates wear compared to highway driving. Off-road conditions demand better tread for mud, rock, and debris evacuation, so don't wait until legal minimums (2/32 inch).
How to Check Your Tires
- Measure tread depth monthly with a tread depth gauge (available at auto parts stores for under $10)
- Look for cracks or bulges during visual inspections
- Check tire pressure monthly and maintain manufacturer recommended PSI
- Rotate tires every 5,000 to 7,000 miles to promote even wear
- Get a professional inspection if tires approach the 5-year mark
Cost and Planning
All-terrain tires for full-size trucks typically cost $150 to $300 each, so budget $600 to $1,200 for a full set. Track your tire purchase date and mileage so you know when replacement is approaching. Sidekick's maintenance reminders can alert you when tires near their replacement window based on your actual driving habits.
