I cannot put a replacement tire on my rear wheel, whatever I do, have spent half a day on this. It just should not be so extremely difficult, I have tools and it is not the first tire I am replacing in my life. It looks as if the tire is just too small, but it has been bought up to specs. The bicycle has 27.5 inch wheels, 2.35 inch diameter tires. This is printed on the front tire that is original, and I bought another with exactly the same numbers. Once I needed to replace a tube on the front wheel and had absolutely no problem in removing the front tire and putting it back.
The clue may be that recently I had the rear wheel replaced. It visually still looks very close to 27.5 inch but could it be that they managed to put a slightly different size for me? The size is not printed on the wheel. What is the "27.5+" tire size I see in the shop? Maybe this is my new size now? Or should I try 29 inch tire?
