Model T Ford Forum: Forum 2013: Same tube front and rear?

If you have a car with 30 x 3 in front and 30 x 31/2 in back, can you get by using the same size tube for both? If so, which tube? I think it would be wise to carry a spare tube, but does it really have to be two tubes?

OK, OK, I know the tubes come in separate sizes. Just wondered if they're close enough to get by with the wrong one in a pinch.

"......wrong one in a pinch." Hmmmm,........OK,.....I'll just let that one go Steve,.....ha,ha,........harold

Seriously though, I think that's a good question, because I'm pretty sure that I've read where the smaller tube could be used very successfully in either 30x3 or a 30x3.5, but as you say, altho' it might work, it might not be considered "good practice"!

I'v done it and it works OK. That's what they sent me so I used them. That rubber will stretch that extra 1/2 inch.

I bought some tubes from Lang's a few years ago that were stamped with both sizes on them. After seeing that I do not see why you couldn't use just one tube for both sizes.

the trouble is, the new junk tubes can not be stored folded up or they tend to crack on the folds. by the time you pull on out of your running board tool box, you will still have a flat tire.

Steve

Just inflate the spare tube and put it in the back seat. If anyone inquires ... your on your way to go tubing ;o)

I bought a tube recently from Lucas, and noted it says 30X 3 1/2, 30X 3, and 31 X 4. It doesn't make sense to me, and I'd hate to see what would happen if I used this tube in a 30 X 3! I hope they know what they are talking about.

I have used 30x3 1/2 tubes in the back wheels(32x4 1/2) on my TT before and they worked fine. Years ago, I also used 7.50x16 tubes in the 750x17 tires on my '65 Chevy 3/4 ton pickup. They worked fine also. Dave

Sounds like the tubes will stretch to fit just about any T rim there is. Bud, would you have to leave the tube inflated when you load it? Seems to me if you leave it inflated in the garage but deflate it to fit in the toolbox? My '23 will have 30 inch demountables, and having a spare tube for long tours would be a good idea, but I don't want to have an inflated tube in the truck bed to worry about.

Langs told me not to use a 30x3.5 tube in a 30x 3 tire. Ed

Steve I bet folks used the same tube for either front or back way back when.
People would get by the best they could and Model T's was the car to do it in.

When we got Karen's '18 Touring, it had 30 x 3-1/2 TIRES on all four corners! If you can stretch a 23" tire onto a 24" rim, I don't believe stretching a 23" tube on there would be much of a feat. Might be a better chance of pinching the tube? Maybe a 30 x 3 tube in the 30 x 3-1/2 tire would be better?

I picked up some tubes from Smith and Jones recently that had both sizes marked on them.

Ed, I agree with your statement. When I install a tire with a tube I always inflate it with the valve core removed to make sure the tube is not wrinkled. I let all the air back out and re-inflate it. If your inner tube is too big you won't be able to get the wrinkles out and the tube will probably leak before long. However, installing a smaller tube will not present that problem.
