Be careful with your spare tire.
I carry my spare in the bed of the truck. On Saturday, while camping in Pennsylvania, 2 hours from home, I put the baby stroller in the truck and broke off the tire valve on the spare tire.
Luckily we didn't need the spare on this trip.
If I had loaded the wheel facing down it would have been safe, but I now question the age of that valve stem since it broke so easily.
This week I'll stop by the tire shop and have the valve replaced.
Next weekend I'll be adding a spare tire mount to the trailer where hopefully it will be safe from baby strollers!
