not sure, but if you measure your stock rims and know how wide those and then measure how far from the fender they are by taping a peice of string to the fender with a weight on it and measuring from the wheel edge to the string you should get the difference and then take the stock width and add double the measurement you just took plus the offset. I dunno if this would cause any rubbing issues when you turn your wheels but this is how i'd figure out how to get the wheel all the way to the edge of the fender. there are also measurements you can take in your wheel well to figure out exactly how big of a tire and wheel you can fit in there, but forgot what exactly you've gotta measure for that.
