Buying a spare wheel for my C-Class

[puffin]

Hi all-

I'm planning a trip on the continent in a few weeks and wanted to buy a spare wheel and tyre in case of emergency.

My car is a 2018 AMG-line C250d with different types front and back (225/45Z R 18 and 245/40 R 18 respectively). I understand that I can get a standard 18-inch space saver that will fit both, but I'm concerned about the longevity of the tyre, particularly if I get a puncture in the middle of nowhere. So I then thought about buying a second hand wheel and tyre. Plenty of places offering them but not sure what size to get.

I can only buy one size of course, so what would people recommend ? Assuming that the puncture was in the 'different size' wheel, would I be better to drive with a 225 on the rear or a 245 on the front for say a few hundred miles ?

Thanks.

Hello and welcome , I can't really answer your question , but if you ever have to drive with wheels of a different circumference never fit them on the axle that has the differential.

Thanks. Thinking further, the 245 may be too wide and may not fit on the front.

I would be surprised if either of the standard wheels & tyres will fit in the spare wheel well, hence the supply of a space-saver as a spare.

There's no space-saver tyre nor a well in the car

if you are buying a full size spare with staggered wheels then buy a front. a rear could effect steering or foul on suspension parts, but plenty of room on the rear driving wheels where you wont feal any difference.

Then where are you going to store the spare wheel, wheelbrace, lifting jack, wheel chock?

simple, you bolt the wheel on the front bumper/grill.

There's only two of us in the car so plenty of room in the rear footwell. As I said, it's only really as 'insurance' for a trip around France.
