Default New To Drag Radials...What Tire Pressure To Start With?

Hello All...

For years I've run 28x10.5x15 M/T drag slicks on the back of my 1993 Mustang notch back. I know drag radials are ultimately quicker when set up correctly (or at least Cleetus McFarland says so...) so I've ordered a set. My cars race weight is 3190 pounds including driver. Below is a link to the drag radials I purchased. My question is what do you think a good tire pressure will be to start with? Any thing else I need to consider suspension wise? It's set up with a 9" rear end, Menscer coil over conversion with a TeamZ anti-roll bar. Also has UPR upper & lower control arms & 35 spline axles. Thanks in advance for your input!

Start higher and work your way down depending on traction. Something in the low to mid 20s to start. Should be pretty quick to dial it in.

on my drag radials and my brothers we run below 20 . otherwise they dont wear evenly . Last year i drove a bunch and 18 to 19 was a good spot . I notice the barely uneven wear and im running 17 now and it feels loose when cold but it spins and goes straight .

Thanks for the input.

When I was on drag slicks I could take the car all the way up on the stall converter (5900 RPM with powerglide) and then dump the transbrake. I know the drag radials are good but that instantaneous dump has me a bit nervous. I'm guessing there is no other way to do it though. I'll find out....
