Wheel/tire fitment

I noticed my tires starting to wear today. Rather than just replace the tires, I was going to replace the after market wheels it came with. I may have missed it but I did a search for any kind of wheel fitment thread. What is the best tire/wheel size to go with? I was looking at doing around a 16" ish wheel. I just was not sure on width/offset. Then would need to figure out what tire side to run with out messing up my speedo or rubbing. What is your go to size for stock height trucks?

 

16-17” typically but could go taller. 6 x 5.5 139.7 lug pattern. 7.5 is stock most aftermarket wheels i like are 8- 8.5” wide but could go bigger again if thats your thing. I believe 5.25 or 5.5 is factory bs or somewhere around there. 4.5 is a good option for fitting in the wheelwell nicely and keeping bigger than stock tires off your control arms. Smaller the backspace number the more ‘poke” and issues with rubbing if you get bigger tires so 4.5 will stick out roughly an inch more than factory

 

What offset and tire size if you go with that?
