31" tyres, how do they behave on road?

After a recent trip, I discovered that 29" tyres don't cut it for rock crawling.

I'm considering 31's, with a T-case regear. How well do they behave on road? Will I still be happy driving at 120kph for long distances? How will it fair as a commuter?

Can't speak for a Jimny but my 31s on my Mitsy behave superbly.

It won't be the tyres that cause problems, it will be the modifications required to make them fit. A steering damper will help improve the feel of the steering. Correcting the caster angle will also help.

what are your plans for the T case regearing ??

I'll likely use one of the gear sets available from Jimny bits. I'll have to start saving my pennies though, I imagine shipping to South Africa is going to cost a packet.

Not sure what you've already had done to the Jimny, but you'll need a major suspension lift, possibly a body lift too, extended brake lines, arch cutting, and a few other things in addition to the castor correction and t-box conversion. Possibly also axle reinforcement, HD panhards, HD steering etc if it's loads of rock gardens you'll be visiting.
