I just had Pirelli Tires installed and don't like them. What you you recommend 185/65/15 or 195/65/15?
185 i/65R15 is the Toyota spec'd tire; installing 195'65R15 will theoretically increase radius of the tire by 6.5 mm (~1/4"), which will have ramifications, such as drag increase, stability reduction, through off the odometer. All slight, but... It will increase ground clearance of course, again, a slight amount.
