Do i need a fullsize spare?

[B-ROCK]

If i'm running 295/75r16, can i get away with a stock spare. I only need it to get me home. What size is your spare compared to what your running and where is it?

I have a 93 Blazer, and don't really want to put it on the roof.

You don't NEED a fullsize spare, but if it were me I would run it on the front if you have a locker/limited slip/G80, even if it meant pulling another wheel and tire to switch em around.

Cons to running it on the front would be a slight pull to 1 side while driving and it may cause your ABS light to come on temporarily, better than taking a chance on the rear diff though

So the difference in height between 31"-33" shouldn't be a problem then?

What if the 33"are on rims with different backspacing? ie spare tire on stock rims?

Not on the front it wouldnt matter other than what I listed above...would be fine on the rear too if it's an open diff
