'86 Bronco Suspension Lift?

[terry85021]

I have an '86 Bronco XLT with the 351w and am considering adding a suspension lift. Does anyone know what the maximum tire size, both hight and width, would be to go with a 4" and a 6" lift.

Thx,

BIGBRONCOS.COM has a spec sheet in their FAQ section, that details tire size/gear ratios, and expected RPM. I have seen 39x12.5's on a 6" lift, the Bronco had fender cutouts, but didn't look like it needed them.
