Tires: Tires on F 350 Dually, aluminum wheels, f 350

Question
Can four of the six tires be of one brand and the inside rear be on another.  This type of rotation saves $400.00

Answer
As long as the tires are closely equal in wear then the brand has no effect.

If you are asking me how to properly rotate the tires then I will give you the pattern that I use on my F350 4x4.

Left Outside to Right Inside
Left Inside to Right Front
Right Front to Left Inside

Right Outside to Left Inside
Right Inside to Left Front
Left Front to Right Inside

If you have aluminum wheels then four tires will have to dismounted, remounted and balanced.

If you have simulators, and you DO NOT have any vibration, then balancing is not required.  Rotation only should suffice.

Hope this answers your question. If not please write me back and I will see if I can help.
