As SpEEdyBL mentioned you will need truggy wheels with 1/2 offset or wider wheel adapter otherwise your front tires will interfere with your body while steering.

I used truggy arms to avoid this problem.
I posted some videos in this thread, this thread and in this one.

Traction increases considerably but you have to shift some wheight to the front of your buggy to avoid wheelies (Due to the higher rotating mass of truggy tires the tendency to wheelie increases). My conclusion after running my buggy with truggy tires was that my truggy with its longer chassis just handles those tires better and is easyer to drive as it does not loose as much grip on power while steering.

othello,

Thanks for your thorough reply. And thanks for the vids. I'll look at them.

What i forgot to mention. Runtime will be reduced with truggy wheels as you need more power to turn their heavier rotating mass and more traction means more power needed also.

There will also be more strain on your drivetrain and electric components and wear will augment.

You will have to adapt gearing to the bigger diameter of truggy tires: Use smaller pinions.
