With that size tire you should do a speedometer comparison to a GPS to see
where you really are. That is  a large tire. Between the oversize tires and
slight bump in HP with the engine monitoring the transmission temperature is
a good idea. I have seen that tire size on the automatics cause just enough
continuous torque converter slip to heat things up and cause failures. If
you really doing 20 mpg indicated and especially if you actually traveling
further you are doing well.

A newbie question to you all--

I have a 2.2 WBX gowesty engine, 1990 Westy, Automatic,  with Generat AT2
Grabber 215/65/16  at 44 pounds

I usually highway drive at 63 mph, 3400 RPM, and average about 20 MPG.    Is
that about right?

What highway speed / RPM  do most of you drive at?   What is your MPG?

Thanks

Stan Shapiro
