fizzer Posted December 15, 2013 Report Share Posted December 15, 2013 (edited) For all those who think "the tire manufacturer knows what is best for their tire, moreso than the car manufacturer!" To be fair I only looked up 3 manufacturers, but you'd probably find the same story elsewhere. Edited December 15, 2013 by fizzer Quote Link to comment Share on other sites More sharing options...
jporter12 Posted December 15, 2013 Report Share Posted December 15, 2013 The tire manufacturers make certain sized tires that can be used on a variety of vehicles. The auto manufacturer determines the proper inflation level of those tires on their vehicle to maintain the best combination of wear, handling, and ride quality of the vehicle they have designed. Over-inflation is much less likely to cause a safety concern as long as it's within the tire manufacturer's spec., than under-inflation as seen in the late 90's with the Ford Explorer tire debacle. Ask almost anyone working at an auto repair shop, tire shop, or quick-lube place, and they're going to tell you that they go by the tire placard on the vehicle, as they should.I would probably lose my job if I refused to go by what the tire placard says. One more thing to throw into the ring on this discussion is that vehicles with tire pressure monitoring systems may throw the light on if the pressure is too far out of the range that the manufacturer has specified.

jporter12 Posted December 15, 2013 Report Share Posted December 15, 2013 I max out my tires then reset the TPMS light. I don't think that will work on all vehicles. The purpose of the TPMS system is to warn of a pressure decrease though, such as a leaking tire. Quote Link to comment Share on other sites More sharing options...
