Professional Opinions Please

Well, I'm not going to the sandbox as of right now so...the quest for truck mods is back on track.

First off comes the lift/level mod: 5100's.

Second comes the tire/wheel mod, and this is where I'm needing the help. I have been around the threads, used the tire size calculator, did my research on +/- offset and back spacing, and I would go to a tire shop if there was one on my little shithole island but theres not so...here it is:

I want 18 in wheels, 18x9 with -12mm or 0mm offset but I can settle with 18x8 or 8.5, and I want 275/60/18 or 275/65/18 tires. The 275/60/18's are very close in size to stock,


from the online tire size calculator

Am I off my rocker to put this tire/wheel combo on a stock suspension with a 5100 level on the front?

I have read the largest size tire to fit on stock is 265/75/16...but no one mentions a larger wheel size...perhaps I am dumb but I don't think I would need a lift to put a larger wheel on there and keep the tire size to match stock as best as possible...please state your thoughts, experience and ideas along with professional opinions regarding my sanity.

 

they dont mention wheel size cause most people stick with their 16's. if the diameter of the tire is the same and your not changing the width the rim size makes no difference if all the other parameters are the same or = to the max allowable diameter

 

I'm running 18x9's with +10 offset (approx 5.4" bs) on 265/65/18's with no issues.

 

I thought the 18x9 with 265's would look a bit weird but I guess not. You're not running a lift are you KPT?

 

I have the billy's at 1.75" and TSB rear. Doesn't look weird at all....
