73 New Wheels

Currently have 225/75R15 on my 2wd, single cab, long bed, 4sp, 390.
I want to go to 17” wheels, but I need to know what rim width and tire size. The current wheels are some universal garbage that doesn’t really sit well on the axles and are ugly.
Any tried and true suggestions are welcome. Thanks

Do you want a lower profile tire with the same diameter as your current tire?

Wider tire?

Or taller, bigger off road look?

Is your speedometer accurate?

What is your rear axle ratio? Are you ok with your current gearing and RPM at cruise?

Is your transmission a truck transmission with the granny 1st gear?

Or taller, bigger off road look? A little, nothing crazy

Is your speedometer accurate? Not a concern atm

What is your rear axle ratio? Are you ok with your current gearing and RPM at cruise? 3.50, not a concern

Is your transmission a truck transmission with the granny 1st gear? Yes granny 1st

. current tire height is really ok, mostly the current rims are trash and figured going to 17”, 8” would be a better option.

I run 17" x 8" American Racing TTO (Torq-Thrust original) wheels and Firestone 235-60x17 FR710 tires. The tires are the same diameter as the stock H78x15 tires that came on the truck, so the speedometer is accurate. The wheels have a satin finish rim and gray texture-painted spokes. Can't get a much more "classic" look than this.
