yes it will the speedo would read low. You'll be going faster than you think. This is due to the larger circumfrence. Check with the tire mfg and see what the rotations per mile are the two series tires. The ration of these two values is how much the speedo will be off. To check it ride down the freeway at exactly 60 MPH it should take 60 seconds to travel one mile (by the mile posts). Use a friend to take the times between the mile posts. In some states the highway patrol will check your speed to verify your speedo.
