Re: Split New Inner Tubes
A few snippets from the below PDF on tube production.
Advantages of butyl innertubes to end users (vehicle owners) In summary, use of butyl rubber innertubes offers a number of advantages to the tire end user such as: • Consistent inflation pressure. • Reduction in tire rolling resistance, due to the better inflation pressure retention, which may improve fuel consumption. • Longer tire life and more even-wear performance. • Longer innertube life due to better heat stability. • Enhanced tire durability. .... Low modulus innertube The concept of “low modulus” innertube compounding is an important parameter for innertubes designed for service in radial ply tires. Radial ply tires have a longer service life than bias ply tires. Moreover, the radial ply construction of such tires results in a higher degree of flexing of both the sidewall and the innertube fitted inside the tire. Thus, not only must the innertube last longer in a radial ply tire, it must do so under conditions that results in a higher stress on the innertube walls and particularly the innertube splice. In this regard, when compared to general purpose rubber innertubes, the advantages of low modulus butyl rubber innertubes could be listed as follows: • Compound processing: - Good flow and green tack, and, - Improved splice properties. ... Guidelines for splicing Splicing, like mixing, is an important step in butyl rubber innertube production and should be performed as efficiently as possible, since splice faults often form a large proportion of total rejects. The worldwide trend of increasing use of radial ply tires has meant that greater performance demands have been made upon the innertube splice which must withstand the higher degree of flexing of the radial tire sidewall and the innerliner splice must continue to do so throughout the much longer life of a radial tire. https://www.exxonmobilchemical.com/~...nual_enpdf.pdf |

Re: Split New Inner Tubes
After the bad experiences I have had with bicycle tubes (splitting in the seams)and tractor tubes ( same problem) in the last 3 or 4 years I will trust my old tubes. I still have the tubes that were on the A I bought in 1990 and even though I replaced tires and tubes back then (USA made) I put the old ones in my tire rack and I'm glad I did.

Why tubes would be more prone to splitting o long those lines, I don’t know but they are not seams IMHO.

Re: Split New Inner Tubes
Do your split tubes say "Made in DenmarK"? If so, they were not new when you bought them and were made for tractors years ago. They were dumped in the USA and as far as I know have a 100% failure rate in just the manner you experienced. Very thick rubber or technically a plastic or whatever tubes are composed of and they fooled a lot of people.

Re: Split New Inner Tubes
Lot of good info here! At my age and tire changing capability, I bought Coker tires and took my Model A ford up to my local repair shop. The owner told me he would remove the old tires, inspect and clean the rust on the rims if necessary, install inner tube rim protectors and new tubes. I have no idea where the stuff came from, all I knew was he stated he had done this before and had no problems with his parts source. And the car was ready the next day. It has been a year and no problems!

Re: Split New Inner Tubes
Been there done this...... use Berts tubes and you wont be sorry. They have the best available tubes.

Re: Split New Inner Tubes
in the last couple of weeks I was excited about buying new tires and metal stem tubes for my late 31 CCPU.
The tubes had metal stems like original. I installed them (extremely careful not to pinch tube) and two held air for about 25 minutes before I heard a "poof" and they lost air. I only inflated to 25 psi. The tubes were marked "made in EEC" I just found this post and am now educated on tubes. Will I be able to salvage the stems and put them in tubes from Bert's or Bratton's? Or Will they have new tubes with the metal stems already installed. Thanks Kris |

Re: Split New Inner Tubes
I bought tubes from macs
4 or 5 years ago, installed in universal tires from Coker, no trouble since. Check the pressure every spring, add a bit of air then usually. No idea what brand or where made.
