[rgood81]

I Have A 88 Gmc Jimmy Sierra Classic...is There Anyway I Can Find Out If My Rear Axle Has Limited Slip?....and Second Im Looking To Get Either 34" Or 35" Tires Dont Know If I Should Get Swampers Or Mud Terrians, I Drive An Average Of 50 Miles On Pavement And The Other Offroad....ive Been Told If I Get Swampers They Will Wear Out In A Year Or Less....what Do Yall Think?

An average of 50 miles a year on pavement or what? If you want a good all-around tire that will wear like iron, get a BFG. To check for limited slip rear, look in the glovebox for code G80, or gun it on slick pavement or dirt and have someone look to see if both rear tires spin.

Explain It Better

I Meant I Run 50 Miles On Pavement A Month....and About The Same Or More Offroad A Month.....

evan with out a lim slip, a open rear end will spin both tires in real loose dirt,
IMHO the only real way to tell is to pull the cover

if you know the axle is original then look in glovebox on that white sticker glued in there and look through the codes for G80

G80 is lim slip\ GM calls it locking diff however,
good luck

If you only run 50 miles per month on pavement than a Swamper will last a long time...................
