Just looking to see if anyone has tried installing 275/65/20 on a stock z71 Suburban. I’ve been looking at mine and it looks like only time it would run is at full lock considering tires are never truly the size they say they are.

Please explain how 18 inch wheel vs 20 inch will increase performance. I have 20s on a 4x4 with z71 package because amazingly that’s how the truck was built and equipped from the factory......

So I’ve done lots of research using search button, so I take it that using a 33 or 34 inch tire on a 16-up 1500 will be problematic due to the different UCAs? I have 17 Sierra 4x4 with a 2” RC leveling kit and torn between 275/60/20 and 275/65/20. It appears I have plenty of room on my truck and have no problems with slight rub and trimming if need be. Looking at Ridge Grapplers but leaning towards Open Country AT3 since the have the mountain peak and so many have Ridge Grapplers in my area. Thanks in advance!
