The front tires are definitely going. I will most likely do the 19.5-4-10 BMI karts tires that are deep lugged V treads on the front with 4 bolt hubs. The rear tires are going bye bye as well because 23s are way to small and it will get hung up on my rutted trials. It will have 26s or 27s on the rear.
And yes it was used for pulls the gentleman before me pulled it two seasons then put the engine on something else. I’m not stuffing a huge engine in probably going to do a 420 cc predator or a Honda.
