Time for new Tyres on my CLS63

[kritdawg]

Thanks all for the input, very helpful. I may end up taking the advice of @Cyclone1 in going a size up on the rear as availability seems to big a challenge. I’m pretty sure that they need replacing in time for my MOT at the start of Feb if I want a pass. I’m struggling to find Michelin or Goodyear in the right/current size for the rear.

@Cyclone1 any issues with running a slightly larger size on the rear?

Perhaps a level below what you're looking for but I've got Avon ZV7 on my C300 and they're spot on. The car came with them on the front, and it had Conti EcoContact on the rear, and there was a very noticeable improvement when they got replaced with more ZV7's. I know a C300 is putting out a lot less power than your C63, but there's a ton of grip on them, and no sign of any cracking or bad wear.

Edit: ignore me I've just seen the profile you need, am sure they will not be an option

I put Z7s on my E55k. I liked the kerb protection they offer.
My days of hooling around are over, so found them more than adequate, even for moderately spirited driving.
I'm obviously not trying hard enough

I ran a size up on the pre facelift CLS63 rears with no issue at all. Think they were 9.5 wide. I will go a size up on my current CLS63 when they need replacing. These are 10 wide so will definitely be fine. Rolling radius changes very slightly.

As an update, I’m now running 295/30 PS4S’s on the rear of my CLS63’s.

How are they? Also looking to change set of rears on my cls63s

They are great, no issues at all and ran the same size on my previous CLS63 also.

Is it OK to run a size up? I've a E63 AMG W212 which have the same tyre size as what you've quoted. The rears in 285/30 are a nightmare to source. Have you experienced rubbing with the 295?

Hi Steve, I’ve ran a size up on both my 218 CLS63’s with no issues at all. No rubbing etc. For the OEM alloys I have fitted (10 in rear) they are fine. They look a little less stretched, have a marginally greater contact patch, marginally higher side wall (30% of 295mm v 30% of 285mm) and the rolling radius change is also minor, so minimal if any discrepancy to mph reading. Also you could argue there is a marginal comfort advantage of running this tyre.

Thanks, mines a 65 plate 63 wagon W212, I'm not sure on how wide the alloy is I assume it'll be the same as the CLS yet I'd need to check. Nieve question here yet how does the side was increase of the profile remains the same at 30?

The side wall increases as the profile number acts as percentage of the tyre width.

So a 285/30 is;

30% of 285mm = 85.5mm (height of the side wall)

A 295/30 is;

30% of 295mm = 88.5mm (height of the side wall)

So a tyre at 295/30 has a side wall height larger than a 285/30 by 3mm.

Hope that makes sense.o

Yeah that makes perfect sense, thanks, everyday is a learning day lol

Would it be better to keep the same principle and do the same on the front? In essence keep the same staggered set up?

Last one, would opting for a 35 profile on the rear, unsettle the car as I've always wondered why the fronts were 30 and rear 35

I’ve never really considered the front as necessary. The rear going to 35 would be a larger side wall change so the better option is 295 as long as the allow width allows it.
