I think Dave Swingle said in another thread that the difference in the tire tread width between a 225 and 235 tire was something like a quarter of an inch. Whatever the amount was, it was small.
On my DeLorean with Grady front springs and stock rear springs, I wanted to have a matching set of raised white letter tires. I bought BF Goodrich Radial T/A tires with 215/60 tires up front and 245/60 tires in the rear. Previously, my car had Cooper Cobras with 215s and 235s, and the oversized fronts made the rear tires look small by comparison. The 215/245 combination looks very good.
Most of my cars are classics (look at my signature), and I've autocrossed and drag raced my 79 Vette with 255/60R15 BF Goodrich tires. They definitely hold up when it comes to spirited driving, though some larger rims with thinner tires might help with autocrossing. But, that would require changing the rims, which I don't really want to do. When the tires did come loose on my 79 Vette during autocrossing, it was very predictable, and I was able to get control back very easily. Keep in mind the weight distribution on the Vette is 50/50, but I was/am happy with the tires.
The Michelin Pilot and Falken 7xx tires that some used with 225s in the rear have been discontinued. I know DPI recommended Kumho tires with 225s in the rear. My friend has those on his car and they work fine, but I heard a rumor that they may have been recently discontinued.
Both of the tire sets I mentioned above are available at Pep Boys, though you may have to order some of the sizes. I had the tires replaced on both DeLoreans within the last year, and am happy with both sets.
