For one thing, the difference between the two diameters is almost 2" .... a
HUGE difference when gearing change is considered. 25.5" compared to 27.4".
However, the subie 2.2 is going to handle this much better than a boxer or
some I4 conversionds will.

I have the option, in a 15 inch wheel, of

205 65 15
225 70 15

I'm wondering how much of a difference in torque and power the 225 70 would
make...

I realize that on the one hand the rpms in third gear automatic would be
reduced in freeway speeds

On the other hand it would slow acceleration and how fast you can go up a
mountain...

I have a suburu 2.2 legacy engine

Would appreciate any input, thanks.
