Whatis your affordable solution?
The cheapest option would be to put some maxxix 751s in 235/85 at $200 a tyre. Yes they are wider than 7.5 16s but not by much. Much cheaper than changing wheels and tyres.
And think what you like. My experience is just different to yours. Doesn't make it wrong.
And isuzurover, my argument has nothing to do with swapping from 16s to 15s. I find narrow tyres fine in sand. But they need a flexible side wall.
