i am about to convert my 2001 90 to a convertible but I am also considering changing the wheels but don't know if I can, given that its been lifted. I wonder if anyone knows it's safe to put narrower wheels on, rather than shorte, as occasionally it's like wrestling with a two ton rhino (although, its great off-road). I bought it lifted so if it cant be done, oh well, I still love it. The wheels are 33 x 12.50 r15 (I think) currently. Photos below. Ange.
