Road trip tire safety: the five minute check before you load the family
The best moment to check your tires is the moment before the trip becomes real. Once the cooler is in and the kids are in, it will not happen.
Pressures first, and cold
Find the placard in the driver door frame, not the number on the tire wall, and set them before you drive anywhere. A tire that has been rolling reads high, so a warm check flatters you.
Then tread, with a coin or a gauge
Look across the whole width, not just the middle. Wear on one edge is an alignment conversation. Wear in the centre is chronic overinflation. Either way you want to know before a wet freeway tells you.
Do the check before the trunk is full, or accept that it will not happen.
Then the walk around
Sidewalls for cuts and bulges, tread grooves for embedded metal and stones, valve caps present. Look at the spare, which is the tire everybody forgets and the one you only need on a bad day.
Load changes everything
A loaded vehicle needs the pressures on the placard for a full load, which are often higher than the everyday numbers. If you are towing, the trailer tires carry the most and get checked the least.
The part you can do once
A treated set seals punctures as they are made, so the most common cause of a ruined afternoon is handled whether or not anybody did the check. It is not a substitute for the five minutes. It is what makes the five minutes less consequential.
In short
If you want the puncture risk off the list before the next trip, start by finding out whether a certified applicator covers your ZIP code.
