265 70 16 tire as spare?

Just got a free 265/70/16 Firestone destination AT tire to use as a spare. I'm running 265/75/16 wildpeaks, will there be any issues using this spare don't wanna grenade my differential.

 

If you do have to install it, put it on the front and don't engage 4x4.

Even if its on the rear for 50 miles it will be fine as a temporary measure.

That said I wouldnt bother swapping the spare out even if its an AT unless its the correct size.

 

Don't get a flat.

 

Ok gotcha ill keep searching for the correct tire size. Is it the weight of the tire that would throw everything off I was under the assumption if the height is correct then it would work?

 

So i managed to get a brand new BFG rugged terrain 265/75 R16 TA for $20 on offer up to match my wildpeak 265/75 R16 AT, will this work as a spare even though the BFG is a TA?
