I am not being mean to Randall, but some food for thought for everyone.
I think that the "REAL" question here is, How old and what is the condition is your spare tire?
Do you even know if you have a spare?
Where is it in the vehicle?
When was the last time you checked the air pressure in it?
Do you have the knowledge and tools to change a flat tire?
Have you "Upgraded" the tool's to change a flat tire?
Added small 2x6's for jack support for "offroad" flat's?
Do you have chocks to help keep the vehicle from falling off the jack when you get the flat tir
