Attention All Tire Professionals!

Dean,
Got out the Load Guide and did some calculating...
The below is calculated on a single wheel application and would not apply to a Dually TV.
A G614 G Rated at MAX inflation of 110 PSI carries the MAX load of 3750 pounds per tire. So if your 4 tires when weighed are 15000# total or 3750# per tire than your PSI would be 110# per tire BUT if your 4 tires only weigh 13660# or 3415 per tire than your inflation should be 95# per tire.

At 110 PSI the MAX load would be 3750#
At 105 PSI the MAX load would be 3675#
At 100 PSI the MAX load would be 3550#
At 95 PSI the MAX load would be 3415#
At 90 PSI the MAX load would be 3300#
At 85 PSI the MAX load would be 3170#
At 80 PSI the MAX load would be 3042#

The above information came from Goodyear's Load/Inflation Tables.

quote:Anytime you run low air pressure it causes heat in the tire and you don't want that. You will for sure have a tire failure.

100% correct.

quote:A proper air pressue will let the tire roll much better and that will get you better fuel mileage.

Also 100% correct

quote:what ever the side wall says thats what I run.

That's the MAX PSI and should only be used so long as the tire is carrying the MAX load.

quote:Tires run cooler when the inflations is correct.

KEYword is CORRECT.

Watch the videos

Michelin RV Tires

Quite lengthy. Second video is more appropriate to this thread.

Good vids Whayne. Should be included in the info packages when you buy an RV. Wanna bet most new driver know very little about either tire care or what to do during a blowout.
