dont forget this either then

o Do not exceed the maximum pressure for the wheel.
o If the maximum pressure for the wheel prohibits the increase of air pressure, then the
maximum speed must be restricted to 65 mph.
o The cold inflation pressure must not exceed 10 psi beyond the inflation specified for the
maximum load of the tire.


I do not argue that they can hold more psi......what I argue is that the TIRE manufacturer's do not know what the "consumer" is going to be doing, driving, loading with an ST tire......all they can do is what they recommend.


again......Goodyear is not the only company out there with reg's on there tires......but it seems to me that there are a lot of them that have a restriction to 65MPH on most application........We all know that most of us are NOT going to drive 65mph in most cases........and if a sign says 70 or 75 mph....we will go that fast most times.


BTW......I dont know what the scientific evidence is with inflating an ST tire 10psi more than what is recommended on the sidewall of the tire. it will NOT carry any more load than what the tire is actually rated for.....and going faster than 65mph and running 10psi more will only make it worse.....WHY?........due to the fact that the average tire will increase in temp throughout a driving.....thsu for every 10 degree's increase in temp......you will get a 1-2psi increase in tire pressure.........so if you go 10psi over....and a tire is 20* over.....it now has 12-14 psi more than what the sidewall of that tire is rated for.................Result.......Catastrophic failure
