Revolutionary Tire Technology Comes Standard
In a significant advancement for SUV safety and convenience, Ford partnered with Michelin to equip select 2020 Explorer models with innovative Selfseal tire technology. This factory-installed solution represents a major leap forward in puncture protection, offering drivers unprecedented peace of mind on the road.

Key Models Featuring Michelin Selfseal Tires:
- Standard Equipment: Explorer Platinum and Limited Hybrid 4WD models
- Optional Upgrade: Explorer Limited 2WD and 4WD variants
According to Michelin's technical specifications, these specialized tires can automatically seal approximately 90% of tread punctures measuring up to 6.35mm (¼ inch) in diameter. The sealing compound consists of a proprietary natural rubber formulation that remains pliable throughout the tire's lifespan.

How Michelin Selfseal Technology Works
Unlike traditional tires that require immediate attention when punctured, Selfseal tires contain a viscous sealing layer bonded to the inner liner. When a foreign object penetrates the tread area:
- The sealing compound immediately flows toward the puncture
- Natural rubber particles fill the void created by the penetrating object
- Air pressure helps force the sealant into the breach
- The compound forms a permanent plug that withstands normal driving pressures
This process typically occurs within seconds, often before the driver becomes aware of the puncture. Michelin's testing indicates that properly sealed punctures can last for the remaining life of the tire without compromising safety or performance.

Self-Sealing vs. Run-Flat Tires: Key Differences
While both technologies address puncture scenarios, they employ fundamentally different approaches:
| Feature | Michelin Selfseal | Traditional Run-Flat |
|---|---|---|
| Primary Technology | Internal sealing compound | Reinforced sidewalls |
| Puncture Response | Automatic sealing | Structural support |
| Post-Puncture Driving | Full capability (if sealed) | Limited distance (typically 50 miles) |
| Ride Quality | Comparable to standard tires | Often stiffer due to sidewall reinforcement |
| Weight Impact | Minimal (2-3 lbs per tire) | Significant (10-15 lbs per tire) |
Industry research indicates that approximately 85% of tire punctures occur in the tread area, making Selfseal technology particularly effective for common road hazards like nails, screws, and sharp debris.

Real-World Benefits for Explorer Owners
The implementation of Selfseal technology in the 2020 Explorer provides numerous practical advantages:
Enhanced Safety
Reduces the need for dangerous roadside tire changes, particularly beneficial for families and those traveling in inclement weather or high-speed highways.

Cost Savings
Eliminates many service calls and towing expenses associated with flat tires. Michelin estimates that Selfseal technology can prevent up to 80% of typical puncture-related service visits.

Convenience
Addresses the frustration of discovering flat tires after prolonged parking periods. The technology effectively manages slow leaks that might otherwise go undetected until air pressure becomes critically low.

Environmental Impact
Extends tire life by preventing unnecessary replacements due to repairable punctures. Michelin's lifecycle analysis suggests this technology could reduce tire waste by approximately 7% annually.

Technical Limitations and Considerations
While innovative, Selfseal technology has specific operational parameters that owners should understand:
- Sidewall Damage: Cannot repair punctures in the sidewall or shoulder area
- Large Punctures: Exceeds capabilities for damage over ¼ inch diameter
- Blowouts: Provides no protection against catastrophic tire failures
- Tire Repair: Professional inspection still recommended after sealing
- Temperature Sensitivity: Extreme cold may temporarily reduce sealing effectiveness
Ford's tire pressure monitoring system (TPMS) remains critical for alerting drivers to any air loss that exceeds the Selfseal technology's capabilities.

Maintenance and Care for Selfseal Tires
Proper maintenance ensures optimal performance from Selfseal-equipped Explorers:
Rotation Schedule
Follow Ford's recommended 7,500-mile rotation pattern to ensure even wear and maintain sealing compound distribution.

Pressure Checks
Monthly pressure verification remains essential, as the system can't compensate for normal air permeation.

Professional Service
Always inform technicians about the Selfseal feature before any tire service or repair attempts.
Replacement Considerations
When replacing Selfseal tires, consider matching the technology for consistent performance across all wheel positions.
The Future of Puncture Protection Technology
Michelin's integration with Ford represents just the beginning of advanced tire technologies reaching production vehicles. Industry analysts predict several developments:
- Expanded Applications: Potential adoption across more Ford/Lincoln models
- Hybrid Systems: Combining self-sealing and run-flat technologies
- Smart Monitoring: Integration with vehicle telematics for puncture alerts
- Material Advances: Next-generation sealants with improved temperature range
As these technologies mature, they may become standard equipment across vehicle segments, potentially reducing spare tire requirements and creating new design opportunities for automakers.
