1987 mgm battery size, diagnosing and fixing no crank

[Tiggie]

In ten miles, you should have noticed an improvement. Warm weather also helps.

How old are they?

I just have to say I am impressed with the engine and battery.

32-35 PSI (whatever gets the contact patch good) and driving to get the tires warm (some highway driving) should get the tires back in round within 10-20 miles depending on how thick the radial bands are and how creased they got. They may take a few hundred miles to get the fine wrinkles out, but the majors should iron out quick.
