Any drawback with fitting 7" wide wheels on a saph?
After a long search I've finally found a set of wheels I like that are also very good quality, but they only come in 7" wide

not ideal, so what are my options, can I safely fit 215 wide tyres or should I keep looking?
7"=177.8mm
7.5"=190.5mm
8"=203.2mm
Obviously none of the above are technically equivalent to a 215 tyre, but there is a big diff between 7" and 8" wide wheel for example.
Might be a relatively straight forward question to some but I've never run wheels that narrow since I bought it back in 2001, and I certainly don't want to be running 205 width tyres either.
