Slicks keep going flat,leaks from sidewall.

[Born To Run]

My MT ET Drags 28x10x15 keep going flat after 2 days.
I put the pressure upto 20+ psi & they go flat in a couple of days.
I took them to the tire shop & we put them in the water tank,they are leaking from the sidewall in a perfect circle about 2.5" away from the edge of the rim,near where they wrinkle.There are like 100 little bubbles all the way around the circumference of the sidewall.The tires are only 1/2 worn according to the wear holes.
Any suggestions?????

do you have race tubes in them?

 

[Hitman]

you should be using inner tubes with slicks

No tubes!! Most drag racers don't use tubes,but if i do i will have to screw rim to tire as the tire moves 1/8" on a pass.

No tubes,why is the sidewall leaking like i explained??

 

[Hitman]

cause they are made for tubes is my guess. The sidewalls are too flexible.

Slicks without tubes will leak down over a period of a couple of days. Nothing new.

yup, slicks leak. i have tried this trick in the past. palmolive dish soap. coat the entire inside. i have had this work, and i have had it only help let the tires hold air only a day or 2 more.

tubes will slow you down, as much as a tenth. your rim should not be spinning on the tire 1/8" per pass, i would look into that. they should of spun about 1/4" to 1/2" total and locked themselves in. did you install rims dry? or with soap?

Most Slicks really need tubes, esp if you don't want this issue. You can try a rubber rejuvenateor/tire snot to try and fill in the pores but keep it away from the bead.

You should not be getting tire/wheel slippage like that though. I bet the installer used a bit to much tire lube to mount.

yes, slicks should be mounted dry. dismount, and clean with brake clean, and reinstall if this was the case. clean the bead of the rim as well. coat the inside of tire with dishsoap. it might not solve your problem, but it might get you week to week. and better control of tire psi at track.

My ET Drags hold air just fine.

I run my M/T drags tubeless but did coat the inside w/ dish soap before I had them mounted. It slows the seepage down some but they still leak around the side wall. I get about 2-3 weeks before they go flat. If you search around other sites, you'll see this is normal for the M/T slicks.

Some sets leak, some don't, some leak slowly.
That is why tubes are "required"
I've had 1 leaky slick out of the 6 I've owned.
If you run brackets or a class where missing a call due to a flat tire can cost you, might as well run tubes, if you're racing for fun, just make sure you have an air tank or a compressor available for just in case.

Tubes are not required.

I've never had my slicks go down between rounds when I didn't pit the car. In fact I often have to remove air as the tire has less cool down time between burnouts.

That being said, I've never run tubes myself, hence why I had the word "required" in quotation marks...

It's funny since M/T's site has a bunch of contradtions on "requirements" and if you talk to some of their staff they say it's OK to run tubeless.

The upside of running tubes are a stiffer sidewall and not having air loss issue over time. The downside is a stiffer sidewall and the need to run rim screws to prevent the stem from being ripped out when the tire spins on the rim.

I run rim screws on mine to prevent the tire from moving on the rim. I would have gone with tubes but I didn't want the stiffer sidewall and didn't care about the air seepage.

Same here.
Its a pain in the ass when the car is in the trailer for a couple of days & one tire or both go flat,then your straps are loose.

 

[StangMahn]

they go down on my uncles car all the time, that's just the way they work

 

[Hitman]

So basically, if you don't want them to leak, use tubes.

Maybe a can of fix a flat would do the trick???
