>>1996790Have you ever inflated an inner tube outside of a tire? It's like a condom.
A road one will go to the size of a tractor wheel without deforming.
25-28 is a miniscule difference. The smaller inner tube is if anything preferable, and i would choose to buy that for a 28 rather than something which was say 28-35.
You can put a 1" tube in a 2" tire, just fine. You can even put a 26" tube in a 700c wheel although installation is a bit annoying.
Even the stated size of tires commonly has 2-3mm variation and i wouldn't be surprised if your '28' tire is actually 25mm, many are.
