I have an 85 Raleigh that until yesterday had never had its rear tire replaced over the life of the bicycle. Before I replaced it, the wheel seemed fairly stiff. I don't know if the old tire was so dried out it ed lending support or what.
I'm wondering if I need to get something adjusted or if a bit if flex is ok. Is this normal?
Edit: by flex, I mean I tightened down the bolts, so the axle is tightly locked to the frame. However, when I first took the bike off the rack, the tire stayed in the same place on the ground, but if I shook the seat side to side, it would hit a frequency where the axle would move side to side, but the rim would sort of flex backwards and forwards.
Also, by stiff I meant it didn't do this before, not that the brakes were rubbing or anything.
Edit 2: There were questions about how well maintained this bike was, the previous owner said it was used as an indoor exercise bike, and when I bought it it it was on the bike exercise stand. It didn't have a front wheel, and based on the wear on the rear tire, I don't think it was used much, so as far as I can tell, it just sat in someone's basement for 30 or so years.
