better yet, dual wheels which are a bit smaller, so that in normal
conditions on hard surfaces they don't touch the ground, but come into play
when needed. Would suffice to have something like 235/85 for the main
wheels and 235/70 for the extra ones, I should think. hmmm, lessee...
235/85 gives you a nominal radius of 15.86", 235/70 gives 14.47". Aye,
that'll work, provided the 235/85 is reasonably well inflated, you get about
1.4" of clearance.
That will help save the wheel bearings, too, as most of the time it'll only
get the normal loading.
so... I'll get designing a suitable clamp system... actually, a sod-off
spacer set and some rather specialized wheelnuts would do, I expect.
