Wheel Offset?
I am looking to get new wheels/tires for my SL500, but I can't get the whole offset issue figured out. Tell me if this is right:
1) Stock is 35/40 on my Turbine wheels.
2) SL55 wheels are 30/33 and have a WIDER stance?
3) So if I get 25/28 wheels, will these stick out even more? Can these even fit?
Basically, as the offset get smaller, the wheels stick out more?
Thanks

FLF55, it depends on the width of the wheels. If the wheels from the SL55 and the SL are the same width, going to less positive offset will push the wheels out. The difference between the 33mm offset and the 28's are only 5mm or less than 1/5 of an inch. If the wheels are 1/2 wider then you're talking 5mm plus 1/4 inch (or 6.35mm) so 11.35mm sticking out ( 7/16 of an inch) further out. One inch wider rim, the 5mm plus 12.7mm or 17.7mm sticking out ( 11/16 of an inch). The same width would look fine.

If same rim width, the LOWER the offset - the LESS rim sticks out .
So it all depends on the rim width.Offset is how far from the center of the rim is the interior contact point with the suspension (where you mount the wheel). Overall, for any car, the lower the offset - the better. I've seen the MB recommendations for wheels and offsets. Some 19/20"x11j wheels had as low as +15mm offset and, on the other end, 18"x8.5j wheels with +45mm offset - all for R230.

I know this is an old thread, but just in case someone is looking to change their wheels, The larger the offset, the further inward the rim will be. the lower the offset, the further out.
Here are the pros and cons of each:
Lower offset: Better clearance from the back of the rim to the suspension parts, better clearance from the face of the brake caliper, but possible fender rub (depends on wheel and tire width.
Higher offset: Less clearance and possible interference with the brake caliper, plumbing, and suspension parts. No problem with fender clearance as the wheel is inset farther.
