Punctured Tyre Near Sidewall - Repairable?

[3Putt]

Picked up a nail near the tyre's sidewall - DOH!

What determines whether the tyre is a throwaway? Don't want to get riped off by the tyre shop!

dunno but if we had runflats like bmw it would be a throw away .

It depends on how close to the sidewall it was.
The more important question is how far did you drive before you noticed.

If more than a hundred or so meters you would have been riding on the sidewalls destroying the structural integrity of the tyre.

It wasn't a blowout - just a slow leak. Still had 25psi.

The puncture is right on the edge of the tread, at the sidewall. But not in the sidewall.

If the rubber thickness there is similar to the tread, it should be repairable. Any thinner, it becomes a safety issue...

Most tyre places err on the side of safety, for a very good reason. If their repair fails and you crash due to tyre failure, they might be held liable for all damages and injuries.

If the hole isn't actually in the tread itself I would be looking for a new tyre - or two if the other one on the same axle is more than 40% worn. There are a lot of stresses on the edge of the tread, particularly on front tyres - this could dislodge the plug they normally use to repair tubeless tyres.

Replacement is expensive, but how much is your car (and the lives of the people it carries) worth ?

I hate it how I almost always get a "throwaway" puncture on a near new tyre, why can't it be on a worn one that I weas just about to replace anyway ?

in my experience with flats over the years i have found that if its anywhere near the sidewall then they throw it. as stated above ^^^^.. they will err on the side of safety.
if its in the tread you are more likely to get it plugged and repaired depending upon the size of hole.

Vic Roads has a vehicle standards bulletin on the subject.

It refers to the Australian Tyre Manufacturers Association but I couldn't find a specific document or website from them.

If the spare is as new and matches the other wheel/tyres for size, style, type, brand, etc, buy a new replacement for the puncture, put the spare on the matching axle, and put the worn tyre back in the boot as the spare.

Totally agree about the safety side of things. I used to be a volunteer firefighter and have seen more than one accident caused by tyres letting go.

(OT bit) I've also done quite a lot of brake testing on trains, which led to a few interesting discussions with an ex-father-in-law (from Vicroads) who reckoned that a 60-tonne B-double with rubber on asphalt travelling at 100km/h took longer (distance and time) to stop than a 120-150 tonne 3-car passenger train with steel wheel on steel rail at 115km/h. He reckoned up to 1km for a B-double or semi in emergency braking, no way any Melbourne train took that long to stop in emergency.
