Similar question as original poster so no new thread:
My tv G rated tires increases from 70 to 80 psi or so after a long run at 90 degree ambient. Temps rise 5 to 10 degrees above ambient. Sunny side a bit higher in both, but not a lot as long as i am rolling. All of the above is without breaking for hours.
On the other hand, all my H rated 5er tires increases from 95 to 120 psi, or so after a long run after a long run at 90 degree ambient. Temps rise 20-25 degrees above ambient 90 degrees. Sunny side a bit higher in both, but not a lot as long as i am rolling. All of the above is without breaking for hours.
After a slow coast to a stop, hubs on 5er are not hot.
All tires are inflated to proper mfg recommended cold psi for next higher load than heaviest load on tire per axle, plus 5 psi for good measure. Seems like the H rated get hotter and have more temp increase. I would have thought it would be the other way around. I would think the H's are built to take it, but wondering if this is a common observation of tv versus 5er changes en route.
