So a truck with 3:73's and 31" tires will dyno the same as a truck with 3:73's and 36" tires?

That's exactly what I thought matt. I saw the same thing at a local dyno. Guy with a 6L had 35" tires and dyno'd....came back with stock tires and put down like almost 20hp morenoooooope.
sorry to burst anyones bubble but if you have a look thru Waynes turbo testing thread, partway thru he upsized to 38s and it hurt the numbers substantially.
Tire size will not affect the max number on the dyno. It will only change the rpm band and the graph. We have been dynoing for 15 years and have done thousands of dyno's , the dyno dosen't know or measure the weight of the tire period, it will use a calculation based on the gear ratio and tire height to achieve the number.
The same truck with different tires may change a few horsepower due to your not going to get the exact run everytime, load etc. Also straping the vehicle down won"t be exact either. Keeping that in mind it may change a few horsepower, I have seen 5-10 hp. difference, with the tire size you are referring to. There is no way your going to get 50 to 100 hp, with tire size.
Well I guess your right, I just dynoed my truck with 34 in. tires and I put down 599hp and then put a set of 195/60/16 which are 25.2 od. and I dynoed at 903hp.
I'm stating a fact that we have not seen a difference, take it for what it's worth as you can see my post's are low for a reason. That's because I'm out in the shop working on these trucks everyday, 5 days a week. And have been doing it for 32 years. Not to mention I have owned a 6.0 since 2004.

If you have the right software and correct the readings right you can make up some for tire size. A good dyno operator can effectively compensate for gear ratio's, tire size and other aspects to give a more accurate number.
Not saying anyone's right or wrong but not all dynos, dyno software or dyno operators are created equal.
Only one way to settle this. Bring the trucks to the track lol. 600 on stock fuel with no nitrous. Dont bye it. His turbos may work. But dont buy 600
