Sumitomo Inflation Chart

[Chief O]

Hi everyone!

I just purchased a 2007 Damon Astoria Pacific with new Sumitomo ST719 255/70R 22.5 tires and can not find the inflation chart for this series anywhere online. Does anyone have a link or pdf?

Thanks in advance!

Thanks for the link but it is for ST747 and ST948 tires.

The Sumitomo website only links to this product description that does not include the inflation chart.

The 719 is the same S-Tech design and I'm confident the inflation table is the same.


There is very little inflation difference among tires that meet Tire & Rubber Association standards anyway - you could safely use a Goodyear or Cooper table for the same size & load range.


Strange that even the big Sumitomotruck tire data sheet doesn't have a secific entry the the 719.

Phew! A bunch of typos in my last makes it almost unreadable! Should say "...doesn't have a specific entry for the 719
