Patching OEM tires
I'll get to the point:
1st. Is it OK to patch the OEM tire?
2nd. Because I drove probably 500 miles on this low tire, should I need to change the differential fluid right away due to possible overheating of the fluid? (Diff. housing and drain bolt didn't feel hot after driving 150 miles on low tire.)
3rd. What are the tell tale signs that the fluid overheated?
(Paragraphs below is why I'm asking these questions)
I noticed that my car was pulling a little to the right, but not all that serious, I wrote it off as sloping road; they usually are for drainage purposes. As I drove home I noticed it getting worse. When I got home, I re-measured the tire pressure and noticed that the right rear tire was low, 7 psi lower than the left rear. Turns out there was a finishing nail in the tire.
Upon searching the forum, I found multiple posts indicated that having different tire pressures between the left and right rear tires can cause the differential to be "working" all the time, which in turn would cause the differential fluid to over heat.
I changed the differential fluid, when there was about 8,000 miles on the car. It was the factory fluid and it came out black. Replaced it with Mobile 1 70W-90, the car now has 9,800 miles on it.
So further questions:
4th. Did I place any substantial wear on my differential?

Plug the tire from inside. You should break tire down and use a special plug that is inserted from inside through the tire to outside. It has a patch made on the plug that seals on the inside and you do not have to make the hole larger and break the steel mesh.
If you use the old standard plug from outside to inside you have to make the hole larger by breaking the steel and water can enter and rust the steel wire.
Tire Centers Inc. which is owned by Michelin will only use the inside to outside plug...
