After waiting for 6 months, my EQA 250 reached me two days ago and I'm really enjoying the car.

While it's 33˚C in Tokyo at present, it won't remain this hot forever. I'm already thinking about my options for snow tires. One idea I have is too get used 18" M-B wheels and put snow tires on those. On one hand it'd be nice to save some money, but on the other hand getting good condition used wheels is "greener."

Does anyone know of problems that can/will arise with doing that? Thanks in advance.

You need to be aware that although wheels from a GLA look the same and will fit the EQA they are thinner material and may lack the strength for long term use on the heavier EQA. I found that out when I bought a wheel to use as a spare wheel for my EQA and while it is fine for that use, I would be wary of keeping it permanently on the car. You also need to use shorter studs if you use the thinner wheel.

FDR, thanks for that info.

My intention has been to use these ”extra” wheels only for three months a year. But, thank you for pointing out the weight consideration.
It could be the usage you propose would be ok as your speeds would presumably be reduced compared to summer time, there will also be a safety margin in the wheels fitted to the GLA as it has the ability to tow a trailer or caravan, as does the EQA but you maybe won’t want to be doing that in winter with your EQA.
GLA weighs about 400-500 kg less than EQA and tows 2000kg compared to the EQAs 1800kg

Is the 18" wheel size that fits the EQA unique within the M-B stable? Again, I know so little about this subject, but I wasn't specifically thinking of a wheel from a GLA. Would something from a C Class, for example, or something still older work - assuming the width of the rim is measured correctly?

I don’t know if any other cars wheels would be better, when I bought my spare wheel I assumed the easiest way to get a perfect replacement was to source a GLA wheel so I didn’t look any further when I got one. As long as the stud spacing, central hole, rim width and offset measurements are correct then any cars wheel will fit, these measurements are available online for all cars but the thickness of the wheel metal would only be found by actually measuring the wheel.
Try www.wheel-size.com for information on wheels, there you can enter your car and it will give wheel sizes and can tell you what other cars have the same wheels. According to that only the EQA and EQB have precisely the same wheels but you can get away with wheels having a slightly different offset (maybe up to 10mm, more than that could cause problems with clearances) if other dimensions are correct eg EQA offset is 53.5mm on a 7.5 wide 18inch diameter whee, Centre hole is 66.6mm, PCD is 5x112mm. GLA wheel is 53mm offset, other dimensions are the same.

Thanks for all the info you're providing about the considerations pertaining to this wheel situation. I'd already gone to www.wheel-size.com and put together this bit of data to give to shops when asking about wheels. Product Rectangle Font Screenshot Parallel
