OIIIIIIIO "8" rims will be great but don't go any bigger you will roll your beads off if you intend to lower your pressure like you say."
Migh seem like a silly question, but why is this so? i understand that there's less pulling 'in' of the sidewall to the rim on a 10" rim as opposed to an 8" rim, is this why the bead tends to roll off - because the sidewall and therefore bead) is effectively more towards 90 deg on a 10" rim but closer to 45 deg with an 8" rim?
the reason i ask is because i have a number of sets of 8" rims but have just recently bought 2 sets of alloy 10's (1 set for each car) and wanted to use 10" steelies for play tyres. 10" rims look tough as guts...does practicality say though i should use 8" rims for a 33/35x12.5" tyre instead??
i also would tend to go off the recommendation for rim width on the tyre (that being 10.5" wide rims for 12.5" wide tyres for example).
