yea i wonder if anybody has put there hypertech setting for tires at the max. like 33" or 35"( cant remember how high it goes). if the odometer runs off the speedometer then it will read less miles than actually driven. that might be kind of illegal but a good idea.

 

The mileage your engine has is 79k. because the difference of 5 mph on your speedo doesnt matter due to the fact that your engine was still rev'ed up to a higher rpm therefore making your engine work harder.

It also gives all the critical dimensions of the two tires.
