I want to get a set of street tires and wheels for my 2013 500 EXC. Problem is I have no idea what size or brand to buy. I've seen a lot of Warp 9 and Behr Germany wheels for sale. And most sizes I've seen are 17 inch rims 3.5 wide in front and 4.25 wide in the rear. Are those good sizes to go with? What about the brands, has anyone heard of Behr? Are the Warp 9 wheels any good? Any input or recommendations would be appreciated. Thanks.
