What size tires to run
Hello. My dad and I are currently restoring a 70 C10 short bed and I have a set of the 6 lug 15x8 rally wheels that I plan to use. The truck will have the 2.5 drop in front and 4 in rear. I want the tires to fill the wheel wells nicely but not be too big. What are your thoughts?

225 75 15 front and 255 70 15 rear for a staggered fitment . Or 235 75 15 if you want same size all around.

Or 15x8 with 255/70/15 tires all around with 4 1/2" front and 4" rear drop like mine. You should look at all the many pictures in the picture threads. When you find a look you like then see the drop and tire specs.

P275/60R15 fits the 8 inch wheel nicely, and is s little lower profile...my opinion...

Re: What size tires to run
a set of 255/70/15 -29" tall tire will keep your speedo close your rpm's lower and you'll still be able to rotate them .
