In response to the AT's or MT's bit.
If you spend a lot of time on road go for AT's. i had Recip Trial's on my Jimny for 4 months, and whilst the road manners were good, i lost any excess power and fuel economy dropped by a huge factor. 5th was all but useless unless the surface was level or down hill.
Ive just put a set of 235/70R15 AT's on the jimny (same diameter as the Recips) and the difference is incredible! Put them on stock Jimny Rims too, they look great and are seated ok on the beads.
