Is your truck lowered or stock height? If stock height, the sizes mentioned won't look right. There wouldn't be enough sidewall to fill the fenders. If lowered though, not a problem. I would go with either a 275/50/17(28" tall), 255/60/17(29" tall), or a 275/60/17(30"tall). These sizes will look good lowered or stock height.
