Hey all...anyone have an idea of how much an ET Street would grow in diameter as speed increases?

The tire is a 26x11.5x15LT ET Street and MT lists it as having a diam of 26.2in. I'm assuming thats cold, not moving, etc.

Reason is, I am trying to relate some datalogs of when my car was on drag radials, to the ET Streets to compare the tune and the HP...but I need tire diameter to come up with a good HP graph with my logs. Surely the ET Street grows a little? I know the radial probably does not grow that much, esp not the 275/40/17 BFG I was running.

Thanks.

I emailed MT...they said for ET Streets its a max of 1.5" at 150mph. Thats what they list on their website for growth on "Mickey Thompson slicks", but I wasn't sure if that was the ET Drags or ET Streets-- apparently it applies to both.
