What drag tire size should I use?

[Jim_PA]

I hope to make another trip to the track this year late summer/early fall.

My 60' times last year were in the 2.4-2.5 second range, and I have a feeling there isn't a whole lot of improvement on the 295/50/15's. My best 60' was leaving the line at about 1200 RPM's and just mashing it from there.

I'm running a 3.73 rear, and I was thinking about getting some slicks around 26.5 or 27" tall would be good for what I have -- is there a way to know what would be optimal? If memory serves, with the 295/50's I'm around 4500 RPM's at 100 MPH.

Drag radials or regular slicks? Brand? Thanks
