Got my grandpa's old truck back, it's in shambles and will need alot of work to be road worthy. One thing being new tires and possibly rims. My dad always had wider tires on the back of his Chevrolet and I loved the look. Due to having four different size tires on all four rims I'm not entirely sure on what size they are in the first place but my original question is how do I go about putting noticeably wider tires on the back and leaving the stock front rim size the same??
