Hope taller tires won't hurt pinion angle too much

I agree with furry stump.
I don't think the extra height will change the pinion angle.
It WILL change (slightly) your instant center in regards to the anti-squat line and center of gravity .
How much it will change, I don't know. You might have to play with shock settings and Calvert bar settings (again).
I'd sure run it with no changes except for the tires, first.
