You're hitting the tire pretty hard maybe the sidewalls need the support of the tube. Maybe more tire pressure running tubeless?

I have never ran tubes but my TA brake and 904 can cut a .012 on a .400 tree so I'd say no.

Just wondering if anyone else has experience a significant increase in chassis reaction time when removing their tire tubes and going tubeless? My usual delay in my box has only resulted in .090 average lights after going tubeless and this is the same setting that averaged .016 RT before the change. It just seems like a big difference.
Can't answer your? but that is alot.I like running tubes cause it puts weight where in needs to be.I was told by old racer that the car would et better with tubes.His theory is it helps push the car on top- end. .090 bulb wow

I run tubes and a stiff sidewall tire for S/R S/G...I have carried .050 in the box on a .400 tree and have had as much as 1.165 in the box on a full tree when I leave off the wood. It does have a 23" tire in front also.
5.53 @ 125 1/8th on the launch control..more left in her!
