Tire size - not again

Need some advice from the wheel and tire gurus.
I bought a set of 8x16 et34 wheels a few month ago and more recently 20mm spacers and lug bolts.
I searched this forum over the last few days trying to find an answer to my question:
Do 225/55 R16 tires fit without issues or do I need to go with 225/50 R16 tires. The car is not lowered.
Thanks for your help.

I use 225/50 R16. That keeps the speedometer correct. I also know that a 225/55 R16 will not work without rolling fenders. You are pushing it with 55's even with rolled fenders.

See the thread

Try it out and let us know. Since the 55 are probably already on there, what do you have to lose? I bet it hits your 560sl air dam. So be careful when turning the wheel.

Maybe not, Fonzi.
I am running 225/50/17 (same width and diameter as 225/55/16) without interference on my 560.
However I am at et37, no spacers.

I just took a good look at my car. The tires are nowhere near interfering with either the fenders or the spoiler throughout the steering range. Also I don't see how the situation would change much with 20mm spacers, except perhaps in case of extreme spring compression.
My advice to RLT61: go for it. Worst case, you can remove those PITA spacers.

In my case the fender only hit when making a right hand turn over a bump. Also at the time I was running stock 560SL springs and the car was riding low up front. Mt best guess is that if I was running the current SLC springs to raise the car up to normal height it probably wouldn't have happened. But the wheel clearance should be designed to clear at the full travel of suspension at any steering angle. So the 55's with 20mm spacers will 99% of the time never be an issue if the car is not lowered and maybe just the rolling is all it would take to get the required clearance.

It will be close.

I think you missed a spot Dugald. They may not hit the front fender or the spoiler but have you checked the inside fender. See the 1st and 4th pictures in the link I posted a few posts back.

Also going to a 17" wheel gives your a decrease in overall tire width, which is why I was able to get 8.5" x 18" wheels on the front of my car. A 16" 34ET wheel will not even bolt onto a 560SL without spacers because the wheel will hit the steering arm. A 17 or 18" wheel will fit with a large ET because the wheel diameter will clear the steering arm.

Hey guys, the only time I have issues with the 225 50 16's is when I put the car in reverse and turn the wheel to maneuver or reverse park. I get slight rubbing on the front spoiler, series two @380 and early 500SL spoiler.

I guess it's pretty much "suck it and see".

Say what?
The width is independent of the wheel size, no?
225mm=225mm
