Is it true that if a nail is emedded in a tire too close to the sidewall the tire has to be replaced?

If its also almost baldIs it true that if a nail is emedded in a tire too close to the sidewall the tire has to be replaced?
Yes.


Where the tread is, the tire has layers of weave to hold a rubber plug in and is stiff enough for a patch to hold on to.


Because the side wall needs to bulge out when you hit a bump, the side wall has little or no weave for the plug to be embedded in and flexes to much for the patch's glue to hold up. Simply after hitting a bump, the fix WILL fail and you have an old fashion blowout.Is it true that if a nail is emedded in a tire too close to the sidewall the tire has to be replaced?
If it is almost bald,it's too much of a liability to the tire shops because if they patch a bald tire and it blows up,DOT can fine them and you can sue them because they let it leave like that and by DOT standards,3/32in.is legally worn out.The tire shops have a certain area in which they can patch it known as the ';crown'; of the tire. As for patching a sidewall,don't do it.If they were to patch a sidewall(and you can if you know what you're doing),the sidewall of the tire flexes with the movement of the vehicle and the patch would come right off making the tire very dangerous.It's all pretty much a liability issue and they don't want the responsibility.
In Texas, it is a law that if the nail is in the sidewall, the tire has to be replaced. I've had this happen to me on three occasions in 20 years.





Apparently patches in the sidewall don't hold well, and cause structural weakness.





I buy the best tires available. It is the only thing between you and the road and going off the road at 60 mph in the rain. (Which I've also done. Tires are cheaper)


And I buy the insurance because it has in fact paid off well.
ok, tire anatomy 101. if you look at the cross section of a tire, the part that has (or is supposed to) have tread, has steel embedded in the rubber. whereas the sidewall has only nylon reinforcements since it does a lot of flexing (like when you hit a bump or pot hole). and as common sense tells you, steel is stronger than nylon. so if you where to put a plug in the sidewall, the, every time you hit a bump the hole would move around the plug and eventually re-open the hole. but if the tire is almost bald, just be smart and get a new one.
Consider the sidewall as the structural part of the tire. The steel


belts are under great stress at this point and are susceptible to


separation and blow-outs if they are damaged.





Especially if they are almost bald... Now there's really no reason


to even think of repairing it...





Good Luck with your new tires....
If the nail is even close to the sidewall, on the part of the tire known as the shoulder, it can't be patched. The curvature and flex will loosen the patch immediately.


Being almost bald, you should replace it anyway. One way or another you will have to replace it soon.
if the hole is in the sidewall then a plug won,t work there because the tire flexes while your driving. if it,s bald then it,s time for a new tire anyway.
yes sidewall patches have been deemed unsafe by the federal government
Buy a new tire. You don't want to risk a blowout. I know it sucks but it happens to many people. Just bad luck.
Because you can't put a patch on the sidewall.
