Please search and read this forum. Tire sizing, wheel offsets has been discussed numerous times. If that fails there are also tire size and wheel offset calculators found through google.

 

Yes, sure. I am searching and will continue to do so. But, so far I am still substantially confused to confidently say that wheels I mentioned will fit as well as tire sizes. I know this forum has many experienced and knowledgeable members. May be someone would be able to provide a direct answer to specific sizes I mentioned in the original post. Again, I appreciate all the help.

 

The sizes you posted will fit without a problem. Final fitment that you are trying to obtain will determine the size of the spacer you would want to run, if any. Some people like more aggressive fitments while others prefer a more conservative look. Take a look at the "Wheels and Tires Setups That Worked" Sticky and scroll through to see what setup you like. Once you obtain the specs of the setups that you like, then you can calculate to determine spacer sizes from there.

Just throwing it out there, I have a set of HRE 545R centers that can be built to whatever specs you like in 18" Step Lip and my set of 19" iForged Variants will be for sale in the next month or so. Let me know if you need any other help

 

I would think the 19X10 with the 50mm offset may be a little high and could rub on the inside. I would think you would need around a 10mm spacer.
The tire sizes would be 235/40R19 and 265/40R19.
If I can help with the tires let me know.
