Has any one ever used tubes in their tires? At least on the front?

Not good. Years ago on the stock car I used to run tubes all the time, but with the low tire pressures on the modified there is too much, deflection, heat and abrashion between the tire and tube. I had to run a tire with a tube the other day and so I put it on the left front and ran the pressure a little higher than normal and it worked. I sure would not do it on a regular basis and never never on the right rear.

I have to disagree I cannot explain you r bad experience with running tubes. I rarely can afford new tires or wheels so I run tubes all the time. I have had good success with them. In fact I got hit in the LR pretty hard and ruined the rim but because of the tube the tire stayed up and I finished the race and made the feature.

I have run some really low air pressures without trouble as well.
Just my luck maybe dont know.

my thoughts exactly, I would never run one on the back, but i have several tires that only have 1 race on them that got knocked down during a race. $85 dollar tires with one race are too big of loss to disgard. The front left seems like a good place since it just skims the ground anyway.

i know what you're saying george. the tube and the tire don't like each other. even with baby powder, they will chafe each other and eventually wear a hole in the tube, especially on the RR. however, i've had good luck running tubes on the front of the car.

I always run tubes on the front and have never had a problem ,Have tried them on the rear once with no success.
With low pressures(15lbs)and a rough track I have blown two tires off the bead on the right front without tubes.With tubes since then on a rough track no problems, Gives me the extra confidence when throwing it in on a rough track.

I have run tubes in both rears several times without problems ( hoosier e-mods LR 10lb / RR 12lb ). The trick is getting the right size tube, if it's not big enough it will not contact the full width of the tread patch, or both sidewalls. I have not had to use any for awhile now so I can't remember what size they were. It was either a truck or tractor tube.

I tried running tubes in my car, didn't work too well. I found out that the tractor type tubes do work best. I ended up only running one on the right front, the rears always popped, and it wasnt needed on the left front.

I found that I could run with one on the RF and the rest just didn't need them. this is of course assuming that you have a beadlock on the RR. Left side doesn't need them

I've ran as low as 6 lbs in my left rear with a tube on my IMCA Modified and never have had a problem with the tube.
I only use Carlisle brand implement tubes they are part #11L-15/16 SL
TR-218 A Valve
Product code : 032247
Here's a link to their site http://www.carlisletire.com/

These tubes are thicker than a normal street tube and the valve stem has a nut that clamps it to the rim.

To everyone that has had a tube problem, was the valve stem area messed up? You might hve spun the tire on the rim and pinched the valve stem.
