Would a defective tire cause a bike to handle squirrly? My front tire seems to be suffering from tread displacement..cracking and pulging along the green side wall. I never put more then 80 psi. 100 is the max. just wondering. I'll swap it with a less attractive tire and sees what happens later.

A hundred and eighteen views and not one efing respond? Geeeez, I'm glad this isn't the suicidal depression forum!
Anyway I discovered a bunch of very loose rear wheel spokes. Extremely loose. Trued the wheel and problem solved.
I did the same thing a couple of weeks ago with the same wheel because of loose spokes. This time I only tighten the spokes to get it trued.
Didnt really want another tire yet.

Sometimes you just have to wait for someone to bite.

Anyway, as long as the tire runs true, it won't usually affect handling. A tire with a wobble, front or rear an make a bike feel like the wheels are loose and wobbling. Also a seriously underinflated tire can be very sloppy when cornering. Usually not an issue for folks who check their tires once in a while, but you can get fooled by a small leak, which drops the pressure without you noticing until you turn.

Are you still alive????
