How do I know if I need new tires?

You may need new tires if your tread is worn to 2/32 of an inch or less, or if you notice cracking, bulges, or uneven wear. If braking distances feel longer, the ride becomes rough, or your steering pulls—especially in wet weather—get your tires checked right away.

What This Means

New tires aren’t just about tread depth. Look at the tread and the sidewalls: if grooves are nearly gone, rubber is separating, or you see bubbles/bulges, the tire’s safety and grip are reduced.

• Tread depth: Use a gauge or the “penny test” (head down). If you can see Lincoln’s head clearly, tread is likely too low.
• Uneven wear: Inner-edge wear can suggest alignment issues; patchy wear can point to suspension problems.
• Vibration or noise: Thumping or a persistent hum can indicate belt damage or cupping.
• Dry rot: Cracks in the rubber—even if tread looks okay—can be a warning sign.

Why It Matters

Low tread reduces traction for stopping and cornering, which matters most on Ohio roads where weather can shift quickly. The National Highway Traffic Safety Administration (NHTSA) reports that about 1 in 4 crashes involving wet roads are related to tire issues. [Source: NHTSA]

For used GMC owners in Findlay, that can show up as longer braking when you’re heading to work, hauling kids, or towing—conditions where consistent grip is essential.

Your Next Steps

1. Check tread today: Measure tread depth across multiple spots, not just the center.
2. Inspect for damage: Look for sidewall cracks, bubbles, nails, and any cords showing.
3. Watch how it drives: If braking feels less confident or the truck pulls, schedule an inspection.
4. Don’t forget the match: Ask for recommendations on tire size, rotation schedule, and whether you should replace in pairs/sets—especially if you’re using a GMC for family trips.
