Stock suspension package info
 

First, I did try the search feature, and obviously didn't find what I was looking for, so please cut my some slack if you think this is a stupid post.

So I'm going to so be replacing all four tires and maybe the spare (if i change tire size). Everywhere I look online has three different suspension packages on the 2000 4dr 4wd LS Blazer; standard, premium ride, and touring. I'm the (atleast) third owner of this Blazer, and I don't have all of the information on thing, despite hunting and searching on my part. So my question is two fold. First, how do I identify which package I have; and Second, does the package I have affect the BF recommended 30x9.5 R15 tire size on stock suspension?

I'm trying to RPO codes, but so far not much luck, so any help would be much appreciated!

Okay, so I looked up the VIN and I've got the Premium ride suspension. So my second part still stands. Thanks!
