Run Flats by Hutchinson (Spartan)

[NWIP]

I now have about 2500 miles since having them installed. Really don’t feel any difference which is good but have noticed an increase in PSI rise (additional 5psi) after driving a while. I run 110 psi cold and would get a 18-19 psi increase prior to installing and now get 24-25 psi increase.

Be interested in others that were getting them installed if they notice the same.

Interesting observation, I have noticed that the front tires, which have the Retrobans installed, run about 5-10 degrees F hotter than the rears.
Thought it might be the tire size difference but may be the Retrobans now that you mention it.

Checking weight per tire load, fronts carry twice the load per tire than that of the rears which may have more to do with temperature.

We are having the Red Diamond ones installed at the Spartan factory next month.

Interesting info, will have to monitor on the way back south after the install to see what we get compared to now.
