I have a 2 inch heavy duty lift and Terrafirma wheel spacers and wants to fit 285-75-16 tires. Will they fit?

 

i had a 32 inch tire on my 03 lifted 2 inch hd springs no spacers i think you should be ok, but you should check it will be pushing it

 

it's not just the tire diameter, it's the tire width AND the diameter which causes the tire edge to hit the front bumper or caster rods when turning....

285 width on a 32dia....probably going to hit the front OEM type bumper...

 

I have an aftermarket bumper put on made by Lucky 8. There already a lot more clearance.

 

Just depends on what wheel you are running. With the spacers you will definitely be hitting fenders when the axles bottom out both front and rear and pending spacer size and wheel you might have issues flexing as well.

 

Even my 265 75/16 rub with the terrafirma spacers.
They wider tires will rub on the fenders under articulation. This can be trimmed, but the rear means trimming into the rear door panel.
