Hey everyone, I just purchased my first four wheeler last week. A white 2009 Rancher 420 ES on ITP SS212 wheels and worn down Sedona Ripsaw tires. (26x9x12 in the front, 26x10x12 on the back). I'm looking at getting new tires soon and I'm wanting to put a slightly wider tire on the front but I'm not sure how large the 420's can handle. I was thinking 26x10x12 Kenda Executioners on the front and 26x12x12 on the back but I'm not sure if they'll fit and if the 12" wide on the back will rob too much power. I'm gonna be playing in the mud quite a bit with it but I also enjoy riding just dirt or gravel trails at different parks. Any help I'd appreciated. I love this wheeler already. It has an HMF exhaust on it so the neighbors already like it. Aftermarket front and rear bumpers too. Thanks everyone!
