Re truing tires = no traction?

Re truing tires = no traction?
I've had an odd problem the last 2 weekends. My car was setup great, started with new tires, after the last qualifier I retrued my tires and had to replace a front, they were Parma cy/mag last week I was using grp cy/mag with the same results, after I cut them down I lost a lot of rear traction, mostly off throttle it would loop. I left the suspension the same, I re-did ride height and droop to make up for the slightly smaller tires (took off .5mm). The only thing I notice is the magenta "look" a little different after being re trued after the sauce is applied. Is there anything I should be doing before re-truing that maybe I am not doing?

I would say make sure they are dry (no traction compound on them).
I true mine forward and back, then I reverse the truer rotation and true them forward and back. They scrub in faster when they hit the carpet. I use 2 sets of fronts to one set of rears and swap the rears every round. The fronts I run each set 2 rounds swapping each round. I found by doing this the tires stay pretty much the same size and you wont have to true as much to keep the mm's the same.

why would you cut your tires again , unless they are wearing out uneven , ck your camber , when you recut tires even if you take 0.5mm of the tire , you got to break them in again and that would take a few laps ............ good luck

I did do about 5-6 laps before the main and I noticed the looping, so I softened the rear before the main trying to correct it, but it was still a problem. I didn't clean out the tires with motor spray, but they were dry.

when you recut the tire , did you smooth it out a cross the top with sandpaper or something like that helps for me when i cut my tires

I would do what turbo said and make sure the tire is smooth using a file or sand paper. Also if the tires were uneven and you made them even the tweak could have changed causing the car to spin out one way. If it was both ways the file is probably the answer.
