To my knowledge, the regulations covering tires REQUIRES the maximum inflation AND the maximum load be printed on the sidewall of EVERY street tire. The printing is allowed to be pretty small and sometimes wheel covers will cover it up, but I think it has to be normally visible even on a mounted tire.

Having said that, there are a number of different interpretations of those regulations and 2 different versions for load/inflation are used

a) Max Load XXXX, Max Inflation YY This is NOT a recommendation, and its does NOT state a relationship.

b) Max Load XXXX at YY pressure. This is also not a recommendation, and it does state a relationship.

Now to prove this, go out to your car or truck and look. The printing is frequently near the rim and pretty small. Do NOT look at your riding mower or your tractor. The regulations do NOT cover those types of tires. However, it does cover motorcycles!
