Euro 560sec widest tire

When I bought my sec it had 245/45/17 tires on chrome Mercedes double five spoke wheels. Those wheels are in real good shape but I bought some Lorinser RS90 wheels and now am wondering if I should be ok with 245/50/17. V Rated Continental on it. I’m under the impression that the 86 560SEC option 822 has the wider front fenders. Could someone confirm this. thanks in advance for any and all advise/suggestions.

Gogs.
