I have a 98 4door and want to run 31 10.5s on stock rim. Does anyone know if I can run them on stock hight?

I had a 98 4door, took 2 inch lift and 2 inch body lift to run 31s

 

for what it's worth, I ran 31's on my 04 with a shackle and torsion bar adjustment lift on some aftermarket 2wd offset wheels and they STILL rubbed pretty bad even after hammering on the fender and trimming the front valance...

 

Everyone's experience varies, but most people need a minimum of 2" of lift to run 31's on a 4 door Blazer. Your best bet in my opinion is to do a 2" body-lift to start, and see where you sit after that. I suggest that simply because it maintains the stock suspension geometry, while getting more room to clear taller tires. After that if you still need more room there are a few different suspension lift options for you to explore. Tons of info on the forum. Good luck!
