Tire tubes or not?

Wondering about tubes in slicks and other DOT legal racing tires. I am honed in on bias-ply only. Do you need tubes if you don't plan on racing? I'm ***uming people use tubes so if the bead slips, you don't have a blow-out? I have a set of goodyear eagles (full slicks) mounted on steel rims with tubes. I had to weld up the "factory" valve stem hole and drill a new hole because the factory hole was in the wrong spot (14 inch wide wheels - The factory hole is near the bead, where the tube's stem was closer to the middle.) Problem is, I want to buy some aluminium rims and mount some M&H or MT ET street type dot legal grooved slicks but I don't want to drill a new hole or weld up the old one and **** up some spendy rims. So do these tires REQUIRE tubes to hold air? Anyone got any idea's? What psi should be run?

 

I would believe that most all slicks require tubes. Some of the smaller ones may not but Check with the manufacture to make sure.

 

In my experience with truck tires, when the rim slips inside the
tire with a tube in it it tares the stem off the tube and goes flat.
The best way is to drill holes in the rim and screw the bead to
the rim.
Good Luck

 

I drive on wrinkle wall street slicks -MT ET Streets- 28x12.5 on an 8 inch rim- bulges just right and i when I air down, it keeps a full patch.

Always ran tubeless, till this newest set, one bled down pretty good, so i put a tube in it, the other bleeds verrrry slowy and i haven't gotten around to putting in the tube.

The tubes i got with the tires (package trade from local guy) had bigger valve stems that required a bigger hole. So we opened one up.- I dont know if there are different size of stems on tubes (these are my first). Haven't wanted to do that to the other one, since it doesn't bleed fast enough. (lazy)

I ran for a while without tubes till i got a set that bled. Even if you find the bleed, you wont be able to patch one from inside as the rubber on the inside is only about 1/2 a mil thick over the belts.

I'd say about 30-40% chance on a bleeding tire.

If you air down lots at the track, you'll need rim screws, or the tire will spin in the rim and take the valve stem right off the tube. Put talc in the tire before you put in the tube.

i say run them without tubes first.
