I found this article awhile back

https://honda-tech.com/zerothread?id=2327951

But i have a few more questions about the issue. I always thought the tire needed to be staked to the rim it seems that this is not true. Do slicks still have a hard bead that seals the tire to the rim ? Also do you need to run certain wheels to be able to stake them to the rim ? Could I run slicks on rotas or another non "drag" wheel ? Also if running a tube does it just install like a valve stem ?

to answer your last question, the tube has, if i remember, a 13/16" diameter stem. i know it is larger than a standard stem so it has to be drilled. pm slicksmh on here and talk to john.

I tried to mount those slicks last weekend and discovered that the bead is so stiff that I couldn't get the bead to seat in the rim. It's also recommended that no more than 35psi of air pressure can be used to seat the bead. I took it up to just over 30psi and it still wouldn't seat the bead.

The sidewalls aren't of any help getting the bead to seat either because the sidewalls are too soft to aid in pulling the bead over the lip.

I take them to the mechanic at the end of my street and he charges me $10.00 to mount them.

ok so what ive gathered is that you can mount them on any wheels. If your running them without the tube then you can just run the standard size valve steams. The tire bead although it says it should not take more than 35 psi to seat will sometimes take alittle more but thats normal.

If you are running tubes the valve steam size is different. Is this size standard on drag wheels, lenso, welds etc. ? But with running the tube it should be more stable at high speeds and hold air better but this will be adding more unsprung weight.

Nobody commented on staking the wheels to the rim ? Can you do this on any rim or just drag wheels ? Where do you drill the pilot hole for the screw ? And what screws do you use ? Also what is the advantage on staking them ?

Isnt staking the slick to the rim just for extremely high horsepower cars where the car hooks so well that if it wasnt staked the tire would spin on the rim?

Tubes are not required.
"Staking" the slick to the rim is more commonly referred to as using "Bead Screws". Mark the tire and rim with white shoe polish or something similar and make a few passes. If the slick slips on the rim more than an inch each pass, you will need to use bead screws. You can buy them at Jegs or Summit. You'll probably need like 8 evenly spaced screws each side of the rim.
You can use any rim, but real drag rims like from Weld, have much thinner metal/lips allowing more of the bead screw to penetrate into the tire bead.
If you are having trouble mounting the tire to the rim and looks like you need more than 35psi to seat the tire, stop and try to use more lube and/or make sure the rim is clean.

thanks man. So with welds is the valve steam size different to run the tubes ? Also running a standard valve steam is fine if running without tubes on normal wheels ?

And lastly do you guys normally balance your wheels or is it not neccessary since your taking so much material off each pass vs a normal passenger vehicle ? I would imagine you would get alot of vibration without balancing though.... ?

I balanced mine just like a normal tire

The sticky weights or bang ons ? It probably doesnt matter i know.

sticky if you want to keep your wheels nice


and for tubes you need to drill the valve stem hole bigger for the tube to fit, but you can still buy just valve stems that fit in the hole in case you want to go back to no tubes

You'll have to ask Weld about the valve stem hole dimensions. I think you may need a metal valve stem too, but check the rule book.

Balance your tire/wheel assembly to minimize the possibility of vibration. There is no standard way, many racers choose between one of the three, and there is no agreement; bubble, static or dynamic. No tire or wheel is made perfect, therefore you should balance. But the method is debated to no end. Bias tires deform and change shape as it is going down the track so the method may not matter, as long as it is done.

I believe stick on style weights is the only option on a race setup. You don't want the weight being flung off. Just make sure where the stick on weight is not in the way of any brake components.

would those fit a normal wheel or are they larger ?

What is the advantage of the metal valve stem ?

I don't think those are the correct valve stems even if they say the stems are available in chrome.

These are the ones I used on our Lenso's:

I think our Lenso's were already drilled for a larger valve stem or had inner tubes before we bought them.

kornerk12

well what stems do I use if im running standard size valve stems ?
