I understand that. Most tires (I don't know about the Firestone ones) have a rated pressure of 35 PSI. People (and dealers) put lower pressure in them to soften the ride. The lower the pressure the more the tire flexes and heats up. 32 is exactly the number I use and would use when going on a cross country interstate trip. Even at max pressure, the tire is going to flex and heat up and thus build more pressure. But you are right I suppose that in this case temperature of the rubber is more critical than pressure in the tire. I have never owned a tire that I only inflated to 28 PSI. > ---------- > From: audrey skrzyniarz[SMTP:[log in to unmask]] > Sent: Friday, August 11, 2000 11:14 AM > Subject: Re: General RANT by Ken > > Darwin , firestone is saying to increase the pressure from say 28 lbs to > 32 lbs not to lessen it in the heat as most of us may like to do to help > the wear factor.
