When I’m trying to fit bigger, wider wheels on my car, and I just need a bit more clearance, I pull this out of my bag of tricks: the Eastwood fender roller tool. Most fenders have a flange on ’em that’s parallel to the ground, and it can potentially cut your tire. Bolt the fender roller onto the hub, turn the handle, and that flange will be curved up flush against the outside-fender skin. Sometimes that extra 1/2″ is all you need.
