No the hose on the spare works great. When we used 33s we would use a 10 ply spare of similar diameter and put it to max psi. Rigged up the locking chuck on one end of a coily hose and a regular chuck on the other. 120 psi in a spare was plenty enough to get 4 33x12.50s from 8 psi to mid to high 20s.
We finally quit when mu buddy's vintage spare exploded in his garage. Still a good method if you ask me just use a fresh spare
