Thinking about selling my new 20"
The MB dealer quoted me
8.5 X 20 front for CAD$863
9.5 X 20 rear for CAD$1068
Local price on the Pirelli Scorpion Zero A 235/45/R20 is CAD$376.95
and 255/40/R20 is unknown, they only have the Bridgestone which is CAD$327.95
By my estimate my rim and tires are over $5K, and I know my wife will run into the curb in no time.
So, I have bought myself a set of 19 inch rim and tires from Tirerack for less than USD$1K, I figure with shipping and tax/duty it might be close to $1.5K and replacement Bridgestones are only $170. So in the long run it will definitely save me a bundle $$$.
I will drive from the dealer directly to the tire shop and have them swap out for the 20s.
My question is "Should I keep the 20 inch or sell them"

Thanks for the advice.
Also, there is alway wheel and tire insurance. For $1k in US they cover rims and tires for 5 years.
To F18BEN, you always should keep the same overall diameter to avoid any callibraions, as EPS and ABS would also need calibration. The way it works is when you decrease size of the rim you increase the tire sidewall (thickness between rim and ground) and vice verso when ppl go to 22's.

The difference between an 18" rim and 20" rim is only 1" of rubber. That is still not enough to clear a normal curb.
Smaller rims are also narrower while tire width is the same, so you have sidewalls bulging out more which prtects the rim. Also extra hight of the tire would make tire as tall as smaller curbs.
That's why I was surprized that 20's are an inch wider than 19's but tire size is the same...we need 255 on 20's not 235.
Keep them for summer fun and buy a set of snow tires on 18" aftermarket wheels for the winter, that's what we and many here have already done.
Good luck and have fun in your new GLK when it arrives!
