nice looking ride. I personally have 235/60/16 tires on my spare 95 SC rims and they fill the wheel gap nicely. My car is lowered so it gives a nice look. for me the gigantic wheel gap is no good at all. you certainly could use more sidewall to even out the stance. If you could get a 235/60/16 without being on a rim and just place it beside the rim and tire thats on there now I'm sure you would like it, they are also fairly wide but not huge. GL with picking some out.
