I just bought a 97 Jimmy and it was missing the owners manual.
I had 2 questions...
1/ What gas grade should i be using? In my old Ford i always used the
cheapest stuff but a couple people have told me i need to use the
"best" in the Jimmy.
Also, i have read a few things about there being trouble with the ABS
braking if you don't have the "right" tires on it. Should i just get
whatever tires the tire guy has or should i get a better grade name
There's no reason to not use "regular" in the USA, 87 octane. Can't
speak to the ABS issue except that my tire salesman (son-in-law) never
heard of it. My tires are oversize with no problems. Wheels with
incorrect offset could be a problem if they rub on the sensor but that's
just common sense.
You can put different size tires on the vehicle, as long as they
are all the same. Most of the GM vehicles can be reprogrammed
to deal with larger tires. You need to reprogram for correct speedo
operation, and the ABS also needs to be able to recognize the
larger tires on most of the systems.
