Biggest tires with factory suspension and low noise
 
This has been asked before but not with the exact combination so bear with me. :

factory suspension no lift or level
want to improve the stance of the truck (wider and potentially a little taller )
want to keep the low noise that I have already with the factory hankooks 275 / 55 / r20

had a chat with my local tire shop but their view was that anything bigger is going to come with a noisy tread and huge price tag.

Anyone got any recommendations and if possible pictures ?

I ran 305/50 20's on my 13 2 wheel drive on stock wheels.

Model year/configuration? 2WD/4WD?

Width and Height becomes a problem quickly. You pretty much have to pick one or the other. 295/70R18 required spacers and a level on one truck I know but they were aggressive which exasperated the issue (large lugs).

285/70R18 (just shy of 34") is the biggest I've seen on a Stock 2WD.
275/65R20 (just over 34") is the biggest I've seen on a stock 4WD.

If you want to improve the stance use wheel spacers.

If your going to go any wider without an aspect ratio increase you are going to exceed TRA recommendations for tire width on the OEM Rims.

Cooper makes some nice quiet mild All-Terrains in the various models of the AT3 line.

This is something I have been thinking about for my truck when the stock tires wear out. 305/50 R20's seem like they should fit and give a little more than an inch more width. They should be just a hair (.04921 inches) taller than stock.

They will likely clear especially on the narrow 7.5" Wheels.
You will have to find a small independent tire dealer most likely to mount them as most majors will not go outside TRA Recommendations which are 8.5" Minimum.

The Stock 20 inch FX wheel is 8.5 at least on the 13-14 Model Year.

I am running 295/55/20 Toyo AT2 on my stock suspension with no rubbing.
