1996 stock rim:how big a tire?

1996 4x4 manual hubs. Bilstien 5100 front and rear, stock springs, shock set to middle setting. Tires that I'm running now are 31x10.5x15

It seems that 10.5 might be as big as I can go with the with since I'm already really close to the ucr. Can I get something a little taller?

Any suggestions?

 

You can certainly go taller, most of the problems with hitting the ucr have to do with tire width and backspacing, however the 1st gen has limited room in the wheel well so a taller tire means a lift and maybe a bit of trimming here and there.

 

I had the tire store try 32 x 11.50s on mine, but they had some interference, so I went back to 31x 10.50s.
