Good logic

Thanx Tuco for the clear explanation and good logic. This form is very helpful and I’m looking forward to using it more!

 

Yeah thanks Tuco.

 

My pleasure guys.

 

Attached is a spreadsheet I made for myself. You can choose a rotation schedule with a total of 4 rotations (one column, shown above), 9 rotations (two columns), 14 rotations (3 columns), or 19 rotations (4 columns). You only have to enter data in two cells in the spreadsheet - one is for the treadlife warranty in the upper left (yellow) cell, and the other is for the the odometer miles at tire install in the upper right (yellow) cell. The spreadsheet will automatically calculate the rest, and let you know at what mileage to rotate.

I suspect most people will choose the 2 or 3 column schedule. The 1 column schedule has too much of a mileage discrepancy, and the 4 column schedule seems like overkill to me.
