I sure do love tires. There’s something about a fresh set of rubber on an R/C machine that brings new life and a new set of possibilities into play. When it comes to crawler and trail truck tires, I have gravitated toward the big, beefy options from Pro-Line Racing’s XL lineup. While these tires fit a 1.9″ wheel, they offer greater width and height when compared to “standard” 1.9″ tires.
