Our 2000 Roadtrek Popular 200 came with Firestone tires, which were very bad and were replaced in less than 2 years.
We now have LT245/75R-16/10 120/116S OPEN COUNTRY AT tires from LES SCHWAB. After 13 years of use, they still show no tread wear and they are very smooth running tires. I am replacing them this Saturday with the very same tires, not because of wear but for concern over UV affect upon the rubber. In my opinion these are amoung the best light truck tires in the market.
