Hi all , first post recently got first Range Rover a P38 '95 petrol .I have got a set of 5 L322 wheels to put on . I know about the spacers and the wheel nuts needed . Question is they need new tyres so do I stick with the same 255/60 x 18 0r should it have a smaller profile to adjust the circumference to match the 255/65 x 16 standard wheels ?
