Radial VS Bias Ply tires for pulling

[roachie]

Blowing the dust off of this one.

Does anyone have any info to add since this was brought up?

Back a few years ago i done a test with bias and radials and found that the radials hooked alot better ( went from mid pact to winning with a tire change ). but the radials like to bounce more then a bias tire. I found that airing the tires up helped the bounce!!!
