Important Considerations

Load Capacity

The Duncan Mountain Wagon has a significant payload capacity. Ensure your tires can handle the weight:

  • Gross Vehicle Weight: ~6,000 lbs
  • Per Tire Load: ~1,500 lbs (with 4 tires)
  • Safety Margin: Choose tires rated for at least 2,000 lbs per tire

Terrain Type

Consider your primary use case:

  • Highway/Street: All-season or highway tires
  • Mixed Use: All-terrain tires
  • Off-Road: Mud-terrain or all-terrain tires
  • Heavy Load: Load range E tires

Climate Conditions

  • Snow/Ice: Consider winter-rated tires
  • Hot Climate: Look for heat-resistant compounds
  • Wet Conditions: Prioritize wet traction ratings

Maintenance Tips

Regular Inspections

  • Check tire pressure monthly
  • Inspect for cuts, bulges, or punctures
  • Monitor tread depth (replace below 2/32 inch)
  • Look for uneven wear patterns

Pressure Management

  • Maintain recommended 35 PSI for normal use
  • Adjust for heavy loads (increase to 40-45 PSI)
  • Check pressure when cold
  • Recheck after driving for 30 minutes

Rotation Schedule

  • Rotate tires every 5,000-7,500 miles
  • Follow vehicle manufacturer's rotation pattern
  • Balance wheels when rotating
  • Align suspension if needed

Common Issues and Solutions

Problem: Uneven Wear

Solution: Check alignment, balance, and rotation schedule

Problem: Poor Traction

Solution: Consider terrain-appropriate tire type, check tread depth

Problem: Tire Noise

Solution: Balance tires, check for cupping, consider less aggressive tread

Problem: Reduced Fuel Economy

Solution: Maintain proper pressure, consider low-rolling-resistance tires

When to Replace Tires

Replace your Duncan Mountain Wagon tires when:

  • Tread depth is below 2/32 inch
  • Tires are over 6 years old
  • Visible cracks or bulges appear
  • Uneven wear patterns develop
  • After a blowout or puncture
  • Performance noticeably declines

Cost Considerations

  • Budget Option: $80-120 per tire
