I ran over a nail and plugged it. The tire (35x12.50x17 gy mtr) loses goes from 30psi to 25 psi in about 3 days.

Does it make sense to have the plug pulled and go for a plugpatch, or what?

 

No cement, just a plug.

 

Thats why I buy my tires from Discount Tire. Lifetime flat repair, balance & rotation.

 

Discount tire does flat repairs for free no matter where you bought it. However I'm not sure if they can fix it if a plug is in it already. Pretty sure its against regulations

 

My buddy works a one can't fix it if it's plugged

 

I am pretty sure this is your problem. Always use cement along with the plug. You can probably push the plug into the tire and replug with new plug with cement. But first make sure it is the plug leaking my dipping it in a tank or running water over it to see if it bubbles.

 

unfortunately worked in a tire shop for years and saw that all the time. If you did not use cement that's most likely your problem. You can push the plug through, and redo it, but I would just take it to a local tire shop and have them do an interior patch and remount/balance. Probably cost $20 but worth it.
