Opinions on putting a 28x10.5 et drag on a 8" rim.
I just ordered a set of 28x10.5x15 ET drags and I have 15x8 wheels with the right bs to make them fit. I am trying to be a cheap ass and not buy the 15x10 wheels right now.
How well is this going to work on a 8" rim? Opinions? Pics?

will work fine, a 10" would spread the tread out better but M/T rates the tire for 8-10" rims per their website. Could have done 28x9 and that would have been a better choice but it'll work out fine.
obviously a 10" rim would be a bit better giving you a bit more contact and stability but the 8" rim will work fine. i went low 9's and a 1.29 60' with a 28x10.5 et drag on an 8" rim.

Agreed.
Add me (and I am sure a WHOLE bunch more) of guys that have run the 28-10.5 on a 8" rim with no problems. I went 9.00's-9.20's with a best of 1.29 60' and a glide on that setup and 9.70's with a 1.30 60' with a stick on that same setup
Edit, almost forgot:
I DID have teh tire screwed to the rim with teh glide, but NOT with the stick combo and tire would move on teh rim on teh stick combo

Cool, now the next question. Tube or no tube? I have run them both way's but I like no tubes for keeping them light. And the dam tubes are like $60 in jegs.

Never ran a tube, ever. Tires lose air, especially with screws, and need to come up with a tank/compressor at teh track, but again, no tubes, ever.
Some do not really have issue's with losing air with no tubes, I did.

I've run with no tubes all along, never put them in. They weigh alot, are expensive and won't stop you from getting a flat, just stop the tire from leaking. They will also make the tire work differently.
No tubes, I've been running on a 28x10.5S et drag on a f body bogarts for the last 2 years, they leak and if I don't air them up once a week they're flat if the car is sitting on the ground (which is why it sits on the jackstands all the time) I just air them up before I go to the track, and while at the track you're always adding or taking air out anyway so it's not a big deal there.
They take about a week to go totally flat, so even on an overnite on the trailer it's not a big deal really.
Screw the tires to the rim right off, 8 screws per side and you should never have any problems, other then the leaking.
Moroso bead screws are a tiny bit shorter too, and generally don't cause the tires to leak as much from what I have seen/dealt with over the years. Put the screws in the tires, then take it back out, squeeze a bunch of silicone in the hole and reinstall the screw. It should help stop them from leaking too badly.
Cool, now the next question. Tube or no tube? I have run them both way's but I like no tubes for keeping them light. And the dam tubes are like $60 in jegs.
Running a tube on a narrow rim does help keep the car stable. I'm running a 28x10.5 tire on a 8" rim and at 10 pounds the car felt unstable at high speeds. I put tubes in then and it feels a lot better.
BTW, go to a tire shop and you can get the tubes for about $15.00ea

You shouldn't be running the tires that low that's why they don't feel stable. There's no resaon to be running that tire at 10 lbs, anything less then 12 is probably too low. I've tried them everywhere between 10 and 16 and I had better 60 foot times at 13 then I did any lower then that.
Every car is different, but I hear people trying to run the tires that soft and I never understand why. You're not working the middle of the tire at all with that little air in them. If ya want to see what i mean, set them to 10 lbs and do a quick 3 or 4 foot burnout in your driveway. You'll see the edges are the only part making good contact when you hit it. Air them up until you get the widest most consistant burnout on tdry pavment, and I bet the car works better there.
Sounds screwy, but try it and see what the car does at the track with the tires aired there. I bet it works better.

I ment 12 but I guess I hit "0" instead of the 2...
Even at 12 my car did not feel stable, I do street drive my car to the track with slicks on it at 25 pounds and it feels fine.
no matter what tire pressure you run, during a burnout it will always heat the center of the tire, when you launch the car you want all of the tire to make contact with the ground. Here is a picture of my burnout and launch...

o.k. that makes more sense. I know I tried 10 once, and only once LOL.
Usually I have the best luck at 13 to 14, unless the track is absolutely garbage in that case I'll put them at 11 cold before the burnout and leave them at 12 the rest of the day (usually gain about 1 lb from the burnout)
Some of the instability could have been coming from having a wide radial trire on the front, alot of people don't like the way that feels @ speed.
Skinny bias ply front with the big slick makes the whole car move around a little, but it's less unnerving then just having the back walking around. Worst thing ya can ever do is try to drive the car strait at speed.... just let it walk around and do it's thing... you start countersteering down track and bad stuff usually happens.

8 inch youll be ok. like the others said 13-14 lbs works the best.Before you mount them get some liquid detergent for dishes and coat the insides of the tire with it and let it dry.Do it a couple of times,it seems to slow down the air leakage.It kinda seals up the pores.
tire pressure depends on race weight. a heavier car will take more tire pressure. a lighter car will require less tire pressure to hook and still be just as stable as a heavier car with more pressure. make sense?

X2 on the dish soap!! It helps alot with keeping the air in the tires.
