Hi guys, I am new to the forum.

I am in need of new tires on my Magnum 425 4×4, and was thinking of getting Zillas. Unfortunately I can not get a set for the stock rims (12×6 front 10×8.5 rear) that I was just going to sandblast and paint. So now I am thinking of buying 12"Delta rims, and putting 25" or 26" Zillas on them. As I am new to owning a ATV, and know little about tires, I was wonder what people with a bit more experience thought of this. I ride 50% soft dirt, 30% hard trail, and 20% mud.

My big questions are:
Am I going to wear out Zillas too fast?
How are the Zillas going to compare to the Dunlop 25x12x10s that I had?
How is a 425cc going to handle these rims and tires

Thank you in advance.
