I am close to putting 33's on my 89 Blazer. After reading what some of the codes meant in my glove box, I found out that my Blazer has 2.73 gears. Should I even think about putting bigger tires on with such tall gears? I don't necessarily want to pay all that money to put new gears in. Any suggestions? And what gear is best for 33's. It will mostly be driven on the street.
