* 205/75R15: This was a very common size.
* 30x9.5R15: This was also frequently used, especially on models with off-road packages.
To know for *certain* what size tires came on your specific 1995 Jeep Wrangler, you should:
* Check the sticker on the driver's side doorjamb: This sticker often lists the original tire size.
* Check your owner's manual: This will also specify the factory recommended tire size.
If you can't find either of those, providing the trim level (e.g., Sport, Sahara, etc.) might help narrow down the possibilities.
