Tires: which tire size?, hercules tires, size tires

Question
On a 15x8 wheel, does one of these size tires wear better than the other? 265/75-15     265/80-15     10.50/31-15  Also do you know if Hercules Terra Trac tires arte radial? I know these tires will fit when I remove lift, but may stick out a little throwing dirt etc. on truck. Thank you for any help on this. Jack

Answer
Jack,

Wear is a property that is more or less independent of tire size and so long as the rim is within the acceptable range, wear shouldn't be an issue.

I do not know anything about Hercules tires, but if there is an "R" in the tire size, it is a radial.  If the "R" isn't there, then they either left it off by mistake or it is not a radial.
