Different Tire Sizes?

Full Discloser: I am not a car person!

I have a new 2023 GLC 300 4Matic SUV. I just noticed that it has 235/55 R19 tires on the front and 235/50 R19 tires in the rear. Is it normal to have different size tires front and rear?

Thanks

Doesn't sound right. Different size tires are normal when the wheels are different widths (i.e. staggered setup), but I've never seen front and rear tires with the same width but different aspect ratios. Essentially your front tires have slightly more sidewall than the rear tires, and that shouldn't be. Check the tag inside the drivers door for the OE tire specs. I suspect it will show both front and rear tires should be size 235/55/R19.

It does seem wrong to me. I’ll check the door and have already reached out to the dealer.
Thanks

Actually, I have the same situation. The difference is to consider the stability and safety.

I am not sure the real reason.

19 inch AMG wheels are staggered. 235/55 R19 tires on the front and 255/50 R19 tires in the rear.
From MBUSA:
“The staggered-width 19-inch AMG® alloy wheels are fitted with all-season tires.”

Hope this helps.

Hi,
I bought my GLC in June this year. However, all my tires are of the same size 235/60 R18. I read on the internet that usually all tires are of the same size, however, if they are different, then they can be different for front and rear axles (that too if the manufacturer recommends), not on the same axle. I suggest you check with the dealer.

Regards,
Ram

In Canada, with the AMG package you get Staggered setup with 235/55R19 front and 255/50R19 rear.

Just want to ask, are the photos in your profile current? I ask because the car shown is not a 2023 (X254), it appears to be an earlier year (X253).
