Has anyone observed a difference in dyno numbers between the SM7 and SM7.5 tires?

 

It's been a few years since I last dynod my SM, and today it was a few hp lower than it used to be.  I am trying to narrow down possible causes, and one of the few differences between the car now and the previous dyno is the tire.  Any insight here is appreciated!

What value is a few HP?

 

Roller dyno or hub dyno?

I have not seen any difference that I could attribute to tires
