[77newell]

The Toyos I ran on the 77 coach rear tires and inflated to 85psi lasted 10 years. I never checked them hot so I can't comment on 107 except to say that my tires were load range "G" which can be inflated to 115 cold (according to Michelin's site, other manufacturers should be the same) so there is nothing inherent about 107psi that is hazardous, if you have been running awhile that pressure strikes me as being on the low side.

Here is an excellent article about temperature and pressure: http://www.bridgestonetrucktires.com/pub...s1/ra8.asp

I know there is some way to get this link to act as one but I've forgotten how to do it.
