i run 235/85/16 insa saharas on my 98 300TDI 90, They raise the 90 by about an inch or so and do fill the wheel arches a lot better. I find they preform very well in the scottish mud,clay and general crap also find them good int he snow. Havent had any scary moments in the rain with them after all its a defender not a bloody sports car so why would you want to whore it around a corner ?? As for wear i have had my set on for a few years now with a lot of tarmac driving and there wearing very well, they have fantastically strong side walls. Once they need replacing i will be getting another set of insa's maybe the special track next time
