Tire Advise Needed for 17" wheels

The wheels on the truck now are 17" ultra wheels if I remember correctly, the current tires are the firestone 225/65/17 front and 235/65/17 rears, as far as the fender flares the serve no purpose other than for looks I kind of like that muscle car look where the fenders are flared to clear wider tires. I am working on making a set for the rear dually fenders that will match whats on the front. My inner 17" wheels that Trevor did had to have the center bore machined larger and then a hub centric spacer built to center it all up on my truck, but then you can keep the same size tire and wheel for the inner and outers on the rear well worth it.

I agree 100%. The same diameter inner/outer rear wheel is the only way I'd roll.
