It's very easy to wreck the NSRs handling with oversized tyres, and it takes a lot of suspension work to get the performance back. Of course, if you're prepared to put the effort in, then no reason not to go bigger, but I always strongly advise not to.

That's not just in regards to fitting over-sized tyres on the NSR rims, but also the fitting, for example, a wider NC30/35 or RS250R wheel with corresponding wider tyre.
