not sure if this will help but a gen4 165 sitting on sled deck beside a 2016 174 tracks touch deck at about the same time but the 174 is approx half dimension on rear wheel longer. i would imagine the 175 would be about the same. so my guess would be 2.5 to 3 inches more track on ground but with spacing of paddles be same amount of paddles for both sleds touching at any given time
