About 2.8 inches at the minimum
Yes, and you would have to get your fenders cut.
It depens on how much lift is on it, but without a lift you should comfortably be able to fit 33x8 sized tires on them with little or no rubbing.
i run 31/50/15 without a lift i get slight rubbing when flexed.
Absolutely yes, 22 inch rims can fit on a 1967 impala. They fit well, its the biggest rim to get without adding a lift to the car.
As big of ones as you can fit under it without them rubbing your fenders
yes, but for a full u-turn without cutting or rubbing you will need a 13 inch lift
Lift it up, and it is out
there will be alot of rubbing.. 33's are ment for a 3inch lift or more but for a 2 inch lift 31's look better and dont rub. I have an '88 without any lift and 31" BFGs and only get rubbing with wheels cranked to the stops. A 2" lift should be driveable with 33s" but serious offroading will require more.
yes, but you will lose turning radius, rubbing and bottoming out. strongly recomend 2 or 3 inch lift
yes but you need 30 serious tires
I'm running 275/60 r 20 and rubbing on both sides on the front. You'd have to have a lift to run 305/55 r20
Yes. In fact you can fit up to 22" without a lift, as long as you get a real low profile tire on it.
