Think of them as tire cousins. But while they share some of the same DNA, the Dueler H/L Alenza goes a step above with a tread compound that can increase fuel efficiency by as much as 10% compared with the Dueler H/L Alenza.

QuietTrack™ technology also creates a quiet and all-around comfortable driving experience. With over 49 sizes to cover most new and popular vehicles, the Alenza AS Ultra tire pairs an exceptionally long tread life with a luxury driving experience to create Bridgestone's most premium SUV, CUV and truck tire yet.

All-terrain (ON/OFF) traction DUELER combines the high-level traction and toughness that full-fledged 4WD vehicles require.

High Load Capacity tyres are tyres which are designed to support heavier vehicles, such as electric vehicles, hybrid cars and SUVs. HL tyres, which despite being the same size and inflated to the same pressure, offer the higher load capacity needed by hybrid and electric vehicles with larger batteries.

Bridgestone Alenza AS Ultra Treadwear and Warranty The Bridgestone Alenza AS Ultra was engineered to deliver long-lasting tread life. With an evenly wearing tread pattern and highly resilient rubber compound, you can expect luxurious comfort and all-season capabilities that last.

The main difference for me is cost, Michelin tyres tend to me a little more expensive than Bridgestone but in my opinion both are very good products and research would be an advantage when choosing which tyre would be best for your vehicle and your needs.

The Bridgestone tyres are primarily produced in the headquarters factory in Japan. But after a few years, the firm began to produce tyres in other countries including the United States, Belgium, Australia, Brazil, China, etc.

An XL load index tyre can cope with a load capacity of up to 750kg (load index 98) and a HL load index tyre a load capacity of up to 825kg (load index 101). This means that a HL tyre's load capacity is almost a quarter greater than that of a standard tyre.

According to ETRTO, high load (HL) capacity tires are extra load tires that are designed to carry a higher load at the same reference pressure. The prefix “HL” must be stamped on the sidewall in front of the tire size designation.
