What are you guys doing and why ?
I am sure there are different opinions,,,,

I "blew" up a tube this weekend at Martin,,,,,,just sitting in the PITS !

Brand new slicks,,,, (but the tubes were not)....

rim screws,,,,,

heard a huge BOOM,,,,,,,,then a hiss,,,,,,

tire was flat,,,,,pulled the tube out,,,and it ripped all the way around......lucky this didnt happen going down the track....

was able to get the tire mounted,,,to hold some air,,,,,,,

Now the side wall seems to be "bulging" out,,,and is touching (more like HITTING BIG TIME) on the inner wheel lip of the rear quarter,,,,,,was not doing that before,,,,,,

I have to pull both tires off and compare the thickness now,,to see if there is in fact a difference in the side wall bulge,,(ie,,,tire with tube,,,vs,,,tire without tube),,,or did something in the rear of the car move around,,,,

I have heard the tubes keep the side wall stiffer ? and the slicks will last longer ?

any downside to running tubes besides the cost ? ( and hassle ? )

thanks for any comments......
