Tires for '75 FJ40 (no lift) current 32x11.5 R15 (1 Viewer)

[Tenn 75 FJ40]

In need of new tires and shocks which have been on for 20 years. Obviously seldom driven. I understand truck will ride better with narrower tread (don't do off-road).

Questions:

1. If I increase to a 33 is there any chance it will rub?

2. If I decrease width to 10.5, will this give me what I am looking for or do I need an even narrower tire, 9.50?

3. Can I still use 15 rim, if I go with 10.5 or 9.5?

4. Brand recommended ?

5. recommend shocks as will?

6. Other thoughts?

Thanks.
