the sidewall is much weaker than the tread and is subject to much more stress. the risk is the side of the tire ripping open like a zipper while you're driving.
edit to clarify - failed plug in tread = flat, usually. pailed plug in sidewall = possible wreck, rollover, et al, plus whatever havoc your debris wreaks after the tire shreds on the interstate.
while your tire rotates, it flattens out on the road and expands when no weight in on it. At 80MPH your side wall expands and contracts probably 15 or more times a second. At what point does it seem that placing a plug on that part of your tire seem like a good idea?
Hahaha people are so dramatic. It's like they've never had flat tires before. Driving slow on shitty tires is no biggie. Tires aren't filled with explosives and gasoline guys
Driving slow on shitty tires is normal to you?
You do realize that even at 40mph a front tire suddenly blowing out is enough to send the vehicle spinning right?
I'd rather not have some pauper come crashing into me on my commute and this happens all the time down here.
"BOOM" and you see some rusted out Civic full of illegals go caraveening across three lanes of traffic, crashing into cars like a pinball machine.
The suck is it's usually other's dying and no one in the Rustbucket Express...

Since we have NO vehicle inspection here in FL I also see a lot of WTF are you still driving that around!. OP, your better off buying a used tire if $$ is tight than relying on a sidewall repair..
