C17/18 TR25 inner tubes

[prothct]

I cannot seem to locate any inner tubes for a 5.25 X 18 tire with a straight stem, all of them are offset. The removed inner tubes say C17 / 18 5.25-6.00 TR25.

20 years ago I had the reverse problem. I could only get straight stems, which made it a PITA to pump up the tyres on wire wheels with the usual shop pump fittings of the time. So I had a tyre shop take off the straights and put on bent stems (about 80 degrees?). No problem since, although they are a PITA to put on and off their very narrow locking ring rims inside in the tyre (I always do it myself).

I finally did find some 5.00/5.30 X 18 motorcycle tubes, luckily they had four left at $16.00 apiece. Thanks for the tip!
