i noticed the front passenger tire on my car has about 4 or 5 of these bubble looking things on the sidewall. i touched them and they felt really spongie. the tire says that it has steel sidewalls so that might help. i have 2 new tires in my garage but these still have 50% or more tread left on them. anyways, is this something that i should take care of right away or can i drive it tonight or at least a few more days without worry?

Heres a pic of one of the bubbles.

nm guys. I did my homework and im going to replace them right now. ill leave this up for a while though so if anyone gets this in the future... DO NOT DRIVE ON THEM!

they're gonna POP!

I had one tire ship to me like that...i was a fool not to request for a new replacement....i even drove it around for a while...then one cold night...BAMMMMMMM.....it exploded....that's a BAD sign...replacement them from where you bought it if they validate it...tell them what you said here, because that is a manufacturer's problem.

Yeh, any sidewall deformities I would not use. Its just problems waiting to happen.
