The same all the way around...maybe?

[woodwiz]

Been thinking of upping my tire sizes on the 70RR. I currently am running the BFG 235-70r-15 redlines from (coker). Would like to go to a Cooper 245-60r-15 or 255-60r-15. Any opinions on mixing these sizes putting the 245-60-15 on the front and the 255-60r-15 on the rear? Or would it be best to run all tires the same around? The spare is a 235-70-15,would i get in trouble running it briefly as a spare in case of a flat?
Thanks,

You can do harm to a sure grip with miss matched tires on the rear in just a small amount of miles.

It is nice to able to rotate the tires

You guys are right on all accounts. Besides a 245-60-15 is plenty wideand rotating is a bonus and not fubar'n the rear end makes it a small sacrifice.
Thanks!
