Tire Inflation
Bones:
That is a substantial difference. Might be a question to ask the manufacturers. A 9 pound difference would have a big affect on the ability to handle & sbrake.
Or when in doubt, just go the averages. :)
DrewKaree:
Think about the question for a second.
What you're essentially wondering is this:
Do I follow the people who manufactured the tire, and made their recommendations based on their tests of the product they produced.
Do I follow the people who made the car, but needed to spec tires to this vehicle they produced, which may or may not be the exact same model tire you currently have on your car.
I have ALWAYS (and will continue to do so) followed the manufacturer of the tire and their recommendations as to PSI, after all, it's in their interest to cover their butts so that the product they produce can be pointed to in court as giving the proper information required to avoid problems.
Besides, Bones can't even stay on his bike, "tyres" or not, and mebbe he sustained a hit to the head in his assident, so what does he know? :P ;)
JCL:
Often times the side of the tire has the maximum inflation, not the recommended inflation. The max inflation is needed for the max weight. This would be unusual for most conditions.
If the tires are stock, or basically the same, then go with the car manufacturere's recommendation.
A little off either way isn't a big deal. A large amount of underinflation plus high speed and temperatures is dangerous, so keep an eye on them.
There are ways to test for correct inflation if the tires are quite different from stock, but I doubt you really need to use them.

I used to go with the tire manufacturer's recomendations but then my mechanic told me I need to go by the vehicles recomendations....
basicaly he told me the same thing JCL just said........

He then said if I was hauling a heavy load or towing something heavy I may need to add more air to adjust for it..........
