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.

245/45 or 235 45 are correctish size for fronts, 265/275 40 for rear

The stock tire size on the SEC is 205/65-15. It has an overall diameter of 25.5". The car's speedometer is calibrated on the stock tires. So any deviation from that diameter will cause the speedometer to either understate or overstate the actual speed. The 245/45-17 tire has an overall diameter of 25.6" which is pretty close to stock. The 245/50-17 diameter is too far off at 26.6". If your car is lowered on shorter springs, clearance will be an issue.

For 17x8 rims ET11, AMG recommends 235/45-17 all around OR 235/45-17 for the front and 255/40-17 for the rear.

For 17x8.5 ET18-Front: 245/45-17 and 17x10 ET17-Rear: 275/40-17.

This car has 255/45-17 with a diameter of 26". The tire size you're asking 245/50-17 is way too big.

Tire diameter is way too big, it is not the 245 width that’s the issue, it’s the 50 series taller tire that’s the issue . It will fit but look like an off roader 4x4

get a 245/45/17

i have 235/45 on my cars I like it a little better for steering feel. 265 rear is ideal, but harder to find. I ended up with 275 but its worked out fine. I dont mind some fatty tires nowadays. 255 is smaller diam and looks more rubberband ish
