Stock is fine just hit it going 45 and youll go threw. But if I were you id just buy some cheap 29inch mud tires used.there is tons of deals on used tires on clist

 

oops, double post.

 

The best way to find out what it's capable of doing and not doing is to go out and try it. Get some decent tires and go out with someone.

I was in the same boat as you a while back and didn't have a clue, I hooked up with a guy with a jeep and a winch and we just headed out and did some driving. I was pleasantly surprised (and so was the jeep guy) at what all it would actually do. It kept up with the jeep no problems at all.I always used to trail ride alone so I never really tried anything that would even remotely come close to getting me stuck. Now I know.

Get out and do it!

 

Went and drove around a construction site in about six inches of pretty slick muddy clay. Had a buddy in the neighborhood with his truck just incase. Got my Chevy COVERED in mud and was so proud of what my blazer was able to handle. then it rained the next four days and my truck went from looking like a badass hurrican Sandy rescue vehicle to a daily driver that hit a puddle. Well, atleast I know what I can do with cheap tires.

 

I'm 16 and just went offroading for the first time today with my buddy who has a 2007 wrangler rubicon with 30" offroad tires I've got a 2003 blazer 4 door 4x4 with auto and Michelin street tires. short story. he got stuck

 

when i first got my truck, i went to the junkyard and grabbed a decent set of tires (only rears). they were cheap and still had some meat left on them. and pretty close to the same size as the fronts. switched them out in the winter and when i was gonna spend the weekend wheeling.

^^these are highway tires. they arent exactly off-road with the "all-season highway tread." there are some good tires out there without going to mud tires if thats not what you are looking for. im going with Hankook Dynapro ATm's. 50K tread life and rim protectors and all that stuff built into the tire. you just have to do some research and figure out what kind of wheeling you want to do. i plan on mostly dirt/sand and some snow from time to time, but nothing deep. there isnt any where out here that i can go legit snow-wheelin. so mostly just desert stuff.
research is your best friend when it comes to making big purchases.

 

Stock, I've had mine going through mud and water up past my door trim with uniroyal loredos. Performed as well as my buddies 08 silverado, until we went to the thick mud, then he got stuck and I just cruised right through in 2wd

 

I prefer the BFG All-Terrains.

First time I wheeled my stock Blazer I used the stock tires. Pulled into the park, a guy on a quad asked if I would help pull a heep out. Sure why not. Pulled him out, he pulled me out, and we wheeled the rest of the day.
