I own a 1969 280 SL Euro model that has bundt wheels. I am currently restoring the car and will be swapping the bundt wheels for steel wheels and hubcaps. I purchased blackwall tires within the past year that are size195-70-R14. I have an opportunity to purchase 5.5" or 6" steel wheels. Two questions, 1): Which size wheels would be recommended for this tire size? 2:) Did Euro models come with whitewall tires or just blackwall tires? Any suggestions would be very much appreciated!
