I run LT285/70 R17 (<33”) with stock spare 285/60 R18 (<32”) I rarely, if ever, find myself more than 45 miles from civilization. 35 years driving without a complete blowout. I’m comfortable with this size spare to get me home if I can’t make it with onboard air in a slow leaker.
I’m sure others that trek far from the beaten path take a different approach.
