My rear wheel rim is a bit wobbly side to side - about 2mm at the maximum. That's a lot, I think, since the tire contact area being larger diameter than the rim wobbles even more than the rim. I think this could be causing or at least contributing to the wobbly handlebar syndrome on my bike.
Some have eliminated the wobbly front end by switching to a different pattern tire, replacing the OEM Pirelli GTS with Michelin City Grip. I'm inclined to go with the sportier Michelin Pure Power SC but that's a topic for another thread. So, before replacing tires, I'll see if the wobbly front end is due to this wobbly rear wheel in my case. I have a spare rear rim with another Pirelli GTS mounted on it (both brand new and balanced from the factory). I'll mount that new rim/tire to see what it does and if it wobbles.
After I take off the wobbly rear wheel rim and tire, does anyone have ideas on how to straighten them? Or perhaps I could straighten them without removing them, by gently pushing in the section that is currently butting out?
Once I get the rim straight, I'll worry about new tires (the rear Pirelli GTS rides like an off-road tire as soon as I lean even a tiny bit into a turn - it's cupped even though it only has just over 2,K miles and has always been properly inflated (cupping is normal, just the tire pattern on the Pirelli GTS seems particularly susceptible to that).
Suggestions? What is the torque for the rim holding bolts?
The rim is not damaged due to hitting something (it is perfectly round radially, only wobbles side to side). I imagine these can be straightened somehow...
