Mastercraft Posted August 29, 2018 Report Share Posted August 29, 2018 According to the IR thermometer, all four of the inside duals are at 10 or 15 deg hotter than the outside tires. The outsides are all the same temp and the insides are the same. Outsides and fronts at about 100 deg. Air pressure at 110 on the fronts and 100 for the rears.

jeffw Posted August 29, 2018 Report Share Posted August 29, 2018 I have a TPMS with temperature, and the inside tires are always a bit warmer. 2007 Volvo 780 Volvo D12D, 465hp, 1650 ft/lbs tq., ultrashift Link to comment Share on other sites More sharing options...
Pete Kildow Posted August 29, 2018 Report Share Posted August 29, 2018 Heat from your brakes will also cause the inside to be warmer. Link to comment Share on other sites More sharing options...
Lance A Lott Posted August 29, 2018 Report Share Posted August 29, 2018 I once read a thread some where in which the person felt that crown of the road made the inside to have more pressure on the road. He advocated runing less psi on the inside tire as he felt that when it heated up they would be the same, causing even tire where. I felt there maybe a small amount of truth to this but I run my tires at the same psi. Link to comment Share on other sites More sharing options...
rickeieio Posted August 29, 2018 Report Share Posted August 29, 2018 I see the same temperature differences, but my steers are consistently a bit warmer than the rest. Makes sense with the most weight per tire. As to the road crown theory, the total road may be crowned, on straight stretches, but most often, in curves, the road is simple "tilted" to the inside to drain water, especially on larger roads (interstates). Even on a two rural lane, the individual lanes aren't crowned, or there would be a "gutter" between lanes.

Lance A Lott Posted August 30, 2018 Report Share Posted August 30, 2018 I could undetstand his point but came up with so many varyations in the road seface that I dismissed his conclusion. But that said i have driven on roads that hat two trenches in them and I can see that they might put more weight on one tire, however I think that it would be impossible to determine which tire it would be. My ton truck tends to wonder back and forth on those stretches of road sometimes bad enough that i drive between them. I would assume the difference in temp comes from slight differences in inflation pressure, tire diameter,brake heat and the outside tire getting more cooling from passing air than the inside tire, that would get my vote.
