Question regarding tubes and rim screws
Do tubes add stability in the top end of the track?
How often do you have to fill up the tire with air if you don't have tubes?
Do you have to use tubes if you screw the slick to the rim?
At what point, 60ft wise, do you need to use screws because of the slick turning in the rim?
Any passionate arguements either way?
My rims are already drilled for screws...I guess it would look pretty ugly if I didn't screw them in
Thanks

--If you run the slicks at low psi, yah.
How often do you have to fill up the tire with air if you don't have tubes?
--every 2-5 weeks depends sometimes you get lucky and sometimes some are leakers
Do you have to use tubes if you screw the slick to the rim?
--no
At what point, 60ft wise, do you need to use screws because of the slick turning in the rim?
--i have gone 1.48's without them spinning
Any passionate arguements either way?
--up to you
It is a crap shoot what is going to happen with screws. Might take weeks, might
be flat in one day.
I run tubes in all my tires now, it is alot less headache.
I key is to rub dish washing soap on the inside of the slick before you mount them.

this year i have 26X11.5 et streets with not tubes or screws. i bought the setup used so don't knew who mounted them, but they leak really bad, they will be totally flat in less than a week.
at 12 psi they are pretty hairy in 3rd and 4th gear going down the track, but it doesn't bother me too much.
i have some wheel screws laying around, prolly gonna take the tires off and screw them and re mount them, but no tubes

so Sean when you gonna let me borrow your 27" tires so i can see if i can quit spinning through the sixty foot
I figured as much weight is out of my car, I'll sacrifice the rotational weight of the tubes for some stability on the top end. I'm not running your average 26x10.5 tire either.
I got a call from Burt "my very good friend" and Burt said the tires are still leaking and they are not leaking from the rim seal, rim screws or the valve stem. I said whats left brother? He said they are leaking through the sidewall. Thousands of little bubbles.
I saw the thousands of little soap bubbles comming from the sidewall with my own 2 eyes. Same thing happened to my brothers slicks a month ago. Hard to believe but this DOES happen.
I now have tubes installed in these leaky set of slicks. I'll use these for the brackets.
I have another set without tubes I'll be running next time I get to the track.
Yes it is a little squirlley at the big end without tubes but not too bad.
