Kumho tires, help requested

[Boss Hoss]

Kumho changed their website manu specs in the last week on there 37 x 13.50 20 tire. The section width noted on the site when i bought my tires was 13.50 but now says 12.50. Does anyone have the ability to look into the site and see when the page was changed and what was changed...or able to pull up the previous spec sheet?

Also, does anyone happen to have the old spec sheet printed out? Online dealers have not updated their info so i have the spec sheet saved and printed(tire rack) but i would love to have one from Kumhos website. Any help appreciated.
