Front wheel spin?

I have changed all wheels on my racing mower build. I put some atv tires on stock mower rims, and I got some rear tire rims on the front,....and now the front tires kind of spin when turning, and the turning radius is compromised and wants to go straight? What is it that I should do to fix this?

Do you mean they slide on the ground and not turn? Having a locked diff can cause that, just lean on the outer wheel and let the inside one spin. And btw if the rims you put on the front dont have bearings or bushings they'll either wear and get really sloppy or seize up and make a real mess of your spindles and front end

Thanks Richie!

Yeah, once you lock the back, right off the bat, lack of steering is an eye opener.

Under steer be the technical term lol. But yeah they all do that somewhat with a locked rear. My simplicity does it if your really trying to make a tight turn, but usually it's not a huge deal. Mostly I don't have to turn that sharp.
