It's an affliction that affects most gearheads: the desire to fit the biggest possible tires onto every vehicle they own. Your author gets overcome with this weakness on a regular basis, it must be noted. While off-road machines generally scoff at the type of abuse that could break a road-going machine in half, one still needs to plan ahead for bigger tires. Depending the size selected, changes to the machine might be needed - whether that's a lift kit, fender trimming, or some other suspension modification will be dependent on your situation.
