Braking News- Max Speed on ST type tires

[Herk7769]

eTrailer is posting the load rating at a given PSI.

I don't recall them doing that before. I stand corrected.

Just messin' with ya'.

Seems 2150 pounds equates to 65 PSI

2150# @ 65 psi is a tire relationship not a wheel relationship.
The wheel does not know what the air volume is of the tire.
Have to consult Load/Infl charts.

??? Sounds like double talk.

The ref of pounds load and inflation pressure when discussing the max rating of a wheel.

I don't know how "2150# equates to 65 psi" should be interpreted unless in reference to an inflation of 65 psi as it relates to a tire load capacity.

Just wanted to point out that you need to know the volume of air (tire size) to equate inflation pressure with load capacity.

Wheels have specific inflation limits which usually relate to the rim flange strength. The load capacity is usually limited by the disk portion of a wheel (where bolt holes are). Since these are two different portions of a wheel they are not tired to each other.

Hope this clears up the confusion.

The reference Herk cited is from the wheel specs. Specs:
•Rim dimensions: 15" diameter x 6" wide
•Bolt pattern: 5 on 4-1/2"
•Wheel bolt size: 1/2"-20
•Offset: 0
•Pilot diameter: 3.19"
•Load rating: 2,150 lbs at 65 psi
•Limited 1-year warranty

Has nothing to do with tire size or volume of the tire itself. It merely states that the wheel will take a load of 2150 with 65psi of air in some size tire. Clearly the limit on the wheel.

I find this thread kind of funny. We are only talking about the difference of 10mph which will only save you an hour and a half on a 10 hour trip and will eat up more gas. When pulling my trailer I try to keep it at 65mph and when I feel adventurous I push it up to 68mph. Part of my enjoyment when traveling is traveling.

Excellent observation. I agree wholeheartedly as that's exactly the way I feel. Don't understand all the controversy over 10psi. Kinda senseless to me.

X10. PLUS I think if you are within about 80% of the MAX load range your're better off going up one LR on your tires and wheels. We have seen how close these rigs get to max load and what happens when a tire shreads. AND how poorly some of the ST tires hold up.

IMO
