i just bought goodyear silent armor 275/65 18 i was wondering if i would HAVE TO put a 2"spacer lifton the roverfor them to fit properly?

will the 275/65 even fit the wheel well?

 

They will fit the Rover wheels, as for the lift, I bet you will find you need it especially if you have over 60,000 miles on your suspension. Rover suspensions have a tendency to drop with use and a Old Man Emu may be something to look at.
