According to www.mickeythompsontires.com , for a relatively heavy door-car with a suspension, they recommend you install inner tubes, or even stiff sidewall slicks.

Well, I don't have stiff sidewall slicks; but I do have racing inner tubes that came with my slicks. However, I'm reluctant to install the tubes because of the extra 3-4lbs they'd add to the rotating weight.

I'm not too worried about loosing air, I check them often enough to keep them up.

So - How many of you door-car racers run inner tubes in your slicks?

I don't run tubes, never have.
I have found that when mounting the slicks I run, if you use some hand dish washing soap inside the tire while mounting it, that just about eliminates all the little leak downs that occur during the non-racing time periods.

We run tubeless with M/T slicks. Dishsoap inside works ok, they leak down 2-3 psi per week.

In my old door car I always ran them tubeless. 26X9, 28X9, 28X10 and then the 14X32's when I tubbed it. Never a problem. Car was ~ 3400 lbs when I started and was ~ 3000 w driver after the back half.

Just coat the inside of each tire with dishwashing liquid (Joy, etc) before you mount them. Only do the inside side walls, not the inside of the tread. The soap will keep them from leaking down (at least slows it way down).

I run the skinnies tubeless too. With soap they don't leak down at all.

I think M/T just wants to sell tubes.

Sorry gang, I'm odd man out here, I run tubes. Always have. Granted it adds a little rotating weight, but it also stiffens the sidewall helping with reaction times and 60' times. And until my car gets faster (which I don't plan on doing) and start pinching the tubes, I'm going to keep running them.

Off topic, even with soap, some tires leak badly without tubes. KK's brother put some new Goodyears on at the end of last year, and they leak so badly (even though they are soaped inside), they would be completely flat overnight. He went so far as to build stands to put under the houseing so the rims wouldnt be on the floor the next day.

kv, you said the magic word about leaks (GOODYEAR). i agree with the other guys on the mt's 3-4 lbs in a week. badyears=flat in a couple of days. also for some crazy reason a tire will slip more on the wheel running tubes.

Not if you put screws in them.

but kv, if i am having no problems running tubeless why would i want to put tubes in them and then have to drill holes in my nice wheels to keep them from slipping? btw i have ran tubes before with the screws but i just feel like if it aint broke dont fix it. of course as slow as my car is it really dont make much difference either way!! lol

But even if I ran tubeless, with as hard as my car "hits teh tires", I would still have to screw them to the rim. Maybe I can see if someone will get a picture of my car and show how bad the tires wad up when it leaves.

Well - apparently this is more a matter of opinion, than of performance.

-- I've got to think Jerry's BBF,tube'd '69 is turning some impressive 60' times with serious bite. No tubes in his slicks.

-- I know Kid V runs 1.35 60'ers at 10 flat... With tubes in his slicks.

-- I recall Dave_C ran a 383" @ 10.70s on 14" Hoosiers....without tubes in his slicks.

-- SteveWs '66 is dang quick, wheels in the air; without tubes.

I guess I simply need to try it with & without in my own setup and see what works best; if I can even tell the difference. :\

Ryan

P.S.
(I appreciate all the responses and the pointer to soap the inside to help prevent leaks too.....)

We don't run screws, I've never checked to see if the tire turns on the rim. But if it does with tubes it'll take the valve stem off and cause a flat w/o screws.

I'd try w/o tubes first and if you have problems you can always add the tubes.

On a bad day. It normally runs 1.33-1.34, and has run one questionable 1.318, and several in the 1.32's. I think if it were to ever get into the 1.20's (very doubtfull), it would be time to remove the tubes for fear of tearing one.

yup ryan, it is pretty much a personal opinion. i have ran them both ways myself with no problems either way. but like steve said, if you do run tubes be sure to install rim screws. good luck

I 've run some 1.22 60 fts. If you do run tubes use some baby powder between the tube and the slick so they won't wad up so bad.

What happens when a soaped up slick gets a hole in it? How do you patch it with that soap film, and you can't tube it either unless you get the soap out, right? If it had a tube you'd just patch the tube and go.

SteveW,
,,,,you concern of, "...and you can't tube it either unless you get the soap out, right?" shouldn't be a problem; however, if you're having problems getting the soap out, check with this guy:

Yeah, I do. You breakdown the slick off the rim, then clean the soap out. Next you air dry it, and patch the hole. Followed by inserting a tube.

If you own crappy rims it doesn't matter what kind of tire you are running, they are going to leak down.
