Imex Pins standard tires on proline rims for a medium to loose suface with proline grey foams work very well as do the proline 40 series bowtie i run a harder foam in the front to prevent little or no side wall roll for those hard packed sufaces, TRC grass tires work AWESOME on the grass the tire was designed for grass, MTR hole shots , i only have 1 set of these & have only used them the 1 time & was traction rolling on a hard packed surface (Need more practice on these, Imex Foams excelent grip on the tarmac i set an Australian MT speed record on these but they do blow off at 125kph ,Proline mulchers these are the best left for bashing ,A must for any racer is balancing all of your tires, i use lead .05mm thick sticky on 1 side,
