What are the biggest tires I can use with my stock differentials and transfer case knowing that I'll be using it for offroading?

 

IMO 32s max on an IFS

 

Skinny 33's or 32's. Lift and trimming is required for both. I like my skinny 33's, but if you wheel in DEEP snow then wider 32's might be better. I have had a few issues since stepping up to 33's and absolutely no issues when I was running 31's. It is a personal preference thing. Also, make sure you know what gearing you have. 4.10's would be awesome with 32-33's. If you have anything higher than 3.42's (3.07's for example) don't go any bigger than 31's or you will cry every time you leave a stop light. LOL!

 

Just for some comparison. I parked beside a stock blazer.



Stock tires are 29". I have 33" = 2" over stock
Stock has no body lift. I have 2" = 2" over stock
Stock has no suspension lift. I have lift shackles, add a leaves and a T-bar crank. = 1.5-2" over stock
_________________
Total = 5.5-6" over stock

Time to get out and play!

 

I would probably say 31's. Stock front end, and rear end can handle that, as well as the gears. 31's can still strain the stock axles with 3.42 gears. Mine is sluggish on the take-off.

By the way...Lebanese food is tied with Mexican food as my all-time favorite!

 

How can I tell what ratio my gears and transfer case are?
I hope the places where you eat Lebanese food are preparing it the right (proper Lebanese) way! I went to some Lebanese restaurants abroad that were not that good nor "real".
For example; here's a recipe by a Lebanese chef in the USA for a Lebanese famous salad "Tabouli"(Tabbooleh), he adds cucumber to it, which is never done here in Lebanon, and if things are not very fine chopped (and use only leaves of parsley and mint, not the whole thing) it will not taste good :P

Check the RPO codes in your glove box OR Decode your vin number at compnine.com

 

very nice blaze

 

I tried that website but it didn't work with my number, knowing that I used the same number before on a different site for Carfax a long time ago and it did work! Here it is: 1GNCT18Z1K0178068
And regarding the codes in my glove box, well I don't know how to decode them...

 

I found divisional RPO description online. Attached
