Thanks for being a voice of sanity (to MY obviously somewhat misdirected zeal). Like I was saying Suhaib Sb, I would NOT run JUST the Swampers, since they'd probably end up killing me in terms of fuel bills, and would ultimately, be pointless for extended journeys on blacktop roads. The tyres I WOULD be using mostly, would be the 295/75/16 tyres I mentioned elsewhere. These are pretty big tyres, as tyres go...although nothing close to the 42 inch tyres, of course.
The engine-gear-diff setup (as well as the body mods, SOA, shackle reversal et al) should be capable of being used for the Swampers AND somewhat "normal" tyres, too. If one of the Swampers bursts (which is perfectly conceivable), I would be incapable of finding a replacement, immediately. If the machine were set up JUST for the 42ers, in such an eventuality, I would be forced to use tyres for which the setup might be completely improper. For the machine to be built EXCLUSIVELY around a specific set of tyres, would make tyre accidents VERY costly indeed.
Hence, my perceived need for the vehicle to be somewhat of an all-rounder (for lack of a better word). Yes...it needs to be lifted. By a LOT. It needs to be widened. By a LOT. Will it be exclusively geared and powered towards just the 42's? I don't think so. When 42's become common fare in Pakistan, perhaps we'll start building "specialised" vehicles, that way. Until that time, we'll probably continue to patch and interface our desires, with practicality, ease of use, economics, and availability.
IS there a "middle way" for such a combination of wheel sizes (385/110/15 and 295/75/16), in your expert opinion? If so, I'd be very interested in hearing more of your views.
