If you want to go to a different size without changing rim size, you can try a 215/55-15 which close the the OE overall diameter but 20mm wider.

There are a few other options below but if you go to a slightly less overall diameter the tire will not fill the wheel well as well and there is already enough of a gap above the tire if you have not dropped it already. (e.g. I have 205/45-17 (24.2" overall diameter) with a 1.5" drop and it looks perfectly centred in the wheel well. I know of others who have 205/40-17 (23.5" overall diameter) also with a 1.5" drop and they complain that their drop is not enough, but because the overall diameter is less the OE size the tire their is more space above the tire and wheel well.)

Quote:People are always asking what tires will fit. I think that it is accepted that up to a 215 section width works--225s are marginal depending on offset and/or spacers. In my mind the diameter is the key measurement--should be *around* 24 inches to keep the speedo happy. I have generated a list of sizes and corresponding diameters (+/- a couple of tenths on an inch depending on brand). I also tried to put some tall and skinny tires on the list for those of us who live where it snows...

Here it is:

175/70-14...23.8"
185/70-14...24.3"
185/65-14...23.5" OE size
195/65-14...24.0"
195/60-14...23.2"
205/60-14...23.7"
215/60-14...24.2"
195/60-15...24.2" OE size
205/55-15...23.9"
205/50-15...23.0"
215/50-15...23.4"
215/55-15...24.3"
225/50-15...24.0"
195/50-16...23.5"
205/45-16...23.4"
205/50-16...24.2" OE size
