I have searched and can't find the exact answer I am looking for. I am in need of new tires and I want to get a bit more aggressive tires. I have an 05 Silverado z71 with the stock 265/65/17s on it. I am putting on the readylift leveling kit tomorrow or Saturday. Would I be able to fit 285/70/17 tires on my truck without it rubbing? I have found a relatively good deal on some Cooper Discovery STT tires and thinking about buying them but I don't want to buy tires that wont fit...
