Bridgestone goes large and narrow

ERJ staff report (BC)

Tokyo – Bridgestone Corporation has launched a "Large & Narrow” concept tire, rated for higher than normal inflation pressure.

The company claims reduced rolling resistance, leading to improved fuel efficiency and hence reduced CO₂ emissions, along with substantially better wet grip.

Bridgestone cites the following technical advantages for the Large & Narrow concept:

• A more consistent contact patch shape

• A rolling resistance coefficient around 30% lower than that of conventionally sized tires (175/65R15)

• Reduced air resistance from narrower profile

• Wet grip performance approximately 8% better than that of conventional tires

The Large & Narrow tire is displayed on Bridgestone's stand at the Geneva Motor Show, starting today (5 March).
