Initial Impressions

These tyres came on a new Toyota Landcruiser in Jan 2024. I was disappointed to see Dunlops fitted as I usually drove on Pirelli or Michelin. Now 3 years and 30000 miles later I’m really pleased with how well they’ve worn. At 18000miles I changed front tyres onto back as they were beginning to show wear at the shoulders. This may have extended their life. They are not as quiet as Michelin but at half the price I can live with the Dunlops. Vehicle was serviced recently at Toyota garage and I was told still a few thousand miles to go and remarked how evenly they wearing down. Will change them at first sign of wet or wintry weather. Overall really pleased with them.
