Yes - they are 5b tires - but they are larger than 5.3 inches (the tires you used in the calculator are Savage tires - not 5b). My 5b bowties are 6.8 inches. So I guessed a little less than that for his tires.

yes sir they are B5's 62 isn't but 10 mph's or so more than i wanted as a top speed. i really would like to keep the speed i have BUT ! i would like for this to be a middle of the road deal nothing on the edge so saying that if i get a CC XL and drop to a 18 cause i'd like just a little less topend would the controller survive ? i'd also like to try 8s with 14 pinion and see if the truck felt more driveable. im far from a newb but this 1717 is just a heli motor gone wild ! i wanted to go as far as Brian015 build but i didnt have the chops !

But you are closer to 80mph top speed if my 6.5" diameter is close. Can you measure your tires so the calculation is accurate?

WOW not reading my own tread ! i need to lower the pinion alot more

6.2 would be fair 160mm is what this digital dohicky saids !
