This is a pair of Pre-mounted BIG BLOX X2Tires. Pro-Line’s extremely popular BIG BLOX tire in X2 compound is now available Pre-Mounted! Introducing the Ultimate Long Wear tire – Pro-Line’s BIG BLOX. Customers and Racers continue to demand higher and higher performance out of 1:8 Buggy Race tires while also requiring tires that last longer and longer. After much consultation and input from top-level Pro-Line drivers both in the U.S., Europe and across the Globe, Pro-Line has developed the BIG BLOX Race Tire to meet these lofty expectations. Large center lugs formed into a grid pattern provide the base for the long wear characteristics and unmatched mechanical grip found by all test drivers. The BIG BLOX tire also pays homage to Pro-Line’s rich racing heritage with Bow-Tie shaped lugs that scoop the Earth and propel your Buggy to the top step of the podium. Great care was taken in detailing the side tread to achieve the same smooth side bite and steering feel found in Pro-Line’s highly successful Multi-time National Champ Blockade Race Tire. The Large Lugs on the BIG BLOX allow racers to choose softer compounds than previously possible while still lasting through long A-Mains. Step into the Big Time with Pro-Line’s BIG BLOX now available in Pro-Line’s new High-Speed and Long Wear European style X Compound. Now you can run exactly what Team Pro-Line used to take on the very best drivers at the IFMAR World Championships!
