I tried using some BFG drag radials, 225 wide,( I believe) to dyno my car with some success. However once the car hit around 750 hp, we could not keep it from spinning on a Dyno Dynamics dyno. Even using 6 straps pulling the car down and into the rollers. My question is, what size and type of tires is everyone having success with for dyno purposes?

See if the dyno shop minds if you use vht on the rollers . It works very well !

That should do the trick.

I had heard the VHT trick, guess it may be time to give it a try. I thought that maybe there was a wheel and tire combo that someone had figured out.

Dang Fastech I just noticed you are like 2 hours from me. Ever go out to the Knoxville meets? I'm planning on attending this summer.

235/60/15 radials would work better than the 225s. VHT or 3m super 77 helps a lot and you wouldn't even need to switch tires probably.

Also look to see the wear on the tires you have. Inflation of the tires also matters when dynoing a car. It will also matter the way the straps are routed. Is there over lap of the straps to keep the pressure down?

+2 you need that dyno sauce!

I bought some 265/50-15 tires to try on the Dyno Dynamics. Hopefully this is enough tire to get me well past 750. GoldieWang, I dont really attend car meets anymore. The closest thing to a meet I go to is the drag strip. I usually run the Civic in the Outlaw events at Knoxville Dragway and Brainerd Dragstrip.
