Within the last 12 months, there has been a Forum post about rubber stemmed tubes and the problems with quality and the stems coming loose. What brand of rubber stemmed tube would you currently buy? A check of two major suppliers currently shows 21" tubes for $16.95 each; one at $18.95 each; two at $20.95 each; and another at $24.95 each.
I don't know what brands these suppliers sell. I don't mind paying the highest price if the higher priced supplier's tubes are better quality than the cheaper suppliers, but if he's selling the same tube as the others, I don't feel like padding his pockets.
I emailed the higher priced supplier, asking him if his tubes were superior to the others being sold and he has not responded to me.
Mostly buy Universal Tire products. Haven't gotten any 21" lately, but the 30" x 3 1/2 rubber stem from Universal are heavy duty, weight 2 1/2 lbs. They are marked Made in EEC.
Have some Lang's supplied, 30" x 3 1/2" rubber stem, with a single blue stripe, and they are light, only 1 1/2" lbs.
Seems more rubber is better?
I think Cooper was the last tube manufacturer in the USA and I believe they no longer make any. Sounds likely those from Europe might be the best. Give Universal a call and see what you can find out.
The tubes I have got from Lucas are nice and heavy. I got some from the big Mac that were real thin. I go for Lucas. Don
I went ahead and ordered from Universal Tire. FYI: I told them that I wanted 21" tubes. they said they sold two kinds. I asked if any were made in the EEC and they said, yes. That's what I ordered.
I also decided to use the EEC / blue striped tubes (30x3 1/2)
As they were nearly twice the weight as the alternative that was originally supplied by the vendor. I'm still very concerned about the quality and life expectancy of both the tyres and tubes offered these days. All four of my new tyres / tubes drop pressure from 55psi to 45 over a few days but do appear to hold that pressure from then on. My 21" 25 year old tyres/ tubes hold 26psi for months. Tyre issues are a real pain and will ruin your day out but what can we do? I too would pay much more for better rubber

I just ordered a set of 21'' Cokers with 4 Coker tubes. My fingers are crossed.....Ordered them thru Summit, free shipping paid for the 4 tubes.
Has anyone had any luck with a small amount of a product called Slime added to the tube? Seems to me that the new rubber being used now days could benefit from a internal type sealer. Have used it on many trailer tires around my rural get-a-way with good results.
