Tire Size Question; All Pro 2" Long Travel with spacers

I have a 2014 Long Bed Dual Cab 4x4 Tacoma.

I have just had the All Pro 2" Long Travel Kit installed. This allows (per all pro) for 33"s to be installed without cutting. I also have 1 1/4 inch wheel spacers (so my stock 16" rims would fit).

I have two questions.

The first is pretty basic. How wide of a tire will safely fit on a stock rim?

Second, with the additional 1 1/4 off space (+ the lift and width from the all pro)…how tall of a tire would fit with a stock bumper and no cutting?

 

To answer question number 2,
33" tire will be the biggest you can go if you do not want to cut, grind or modify in any way your inner fender wells, pinch welds, bumper, front cab mounts or fender flares

 

Thanks.

So my remaining question would be:

Can I put 285/75/16's on my stock Taco Rims?

 

Yes
