> [@LoudThunder](#): > > You will need to remember that the tire sizes are different and later, when (rather if…) you rotate the tires, the larger tires will affect the indicated speed of the vehicle. 1st thing the prior customer already put the wrong size on the vehicle, so the speedo would have already been off, the OP has put the correct tire size back on the vehicle and in the rear, so at that point the speedo will be correct… Now the difference in tire size is very minimal and only 0.2" between the two in diameter, and on top of that at 70 mph the speedo is only off by 0.6 mph, considering every obd2 vehicle I have ever tested, the speedo is off by 1 to 2 mph already, making you think you are going faster than you are… I have GPS tested this, radar tested this and Live Data VVS and ABS sensors tested this… Besides the smaller prior owner size would show faster anyway… As I already said not much mechanically different, but as Capri said, the main concern is handling/braking in an emergency maneuver… [Previous page](https://community.cartalk.com/t/what-happens-if-you-put-bigger-tires-on-the-back-of-a-fwd-car/198778.md?page=1)
