Hi guys,

I'm looking to replace my tyres on my M235i - with OE m436's

As many of you know the front suffer from uneven tyre wear, so i'm debating weather to stick with the OE;

Michelin Pilot Super Sport - from: £119.70
225/40 ZR18 (88Y)

or change. Is anyone running the following;

Michelin - Pilot Sport 4 - from: £97,90 each
225/40 ZR18 (92Y)

or any other recommendations are welcome..

The cost is not the issue here..

I was asking for advice on which is the better tyre, just because it's more expensive doesn't mean it's better.

I know some people changed to the Michelin Pilot Super Sport 225/40 ZR18 (92Y) as the sturdier side wall gave less uneven ware issues.

"The replacement for the Michelin Pilot Super Sport has been announced - the Michelin Pilot Sport 4 S"

"Where does the Pilot Sport 4 sit?

- While Pilot Sport 4 replaces the Pilot Sport 3, it's an improvement on the Pilot Super Sport, not a "new" Pilot Sport 3, in design and technology. In comparative testing in 18" sizes, Pilot Sport 4 outperforms the Pilot Super Sport in 99% of everyday situations, with the added benefit of 10-15% improved wear. The other 1% is on a dry track where the Pilot Super Sport would outperform the Pilot Sport 4 by a couple of tenths of a second around a long track. For more track focused track drivers we will expand the range of Pilot Sport Cup 2 over the next few years."

I have exchanged a few emails with Camskill who have been very helpful regarding the MPSS and PS4S situation.

I enquired about a 18" MPSS size that is currently out of stock. I was advised that Michelin ramp down summer tyre production at this time of year and start back up around January (makes sense). This specific 18" MPSS will be back in stock in Feb/march time.

Regarding the PS4S, Michelin haven't released a production date for any 18" sizes meaning no plans to release any in the next 3-4 months. If/when a production date is released the tyre will be 3-4 months away from being available.

I'm looking to change tyres next month and if the MPSS size still isn't available then I will just go PS4. I've heard they are very good from a few owners running them.

Hope that helps.

I've had the Michelin - Pilot Sport 4 - 225/40/18 (92Y) fitted to the Front - £230

I'm getting Michelin Pilot Super Sport - 245/35/18 (92Y) fitted to the Rear this weekend - £314

£544 all in, for new tyre all round. Not too bad considering some of the prices I've seen online while shopping around.

On Michelin's Instagram they announced the MPS4S back end of last year. In the comments someone has asked when 18" will be available in the US. Michelin replied saying March in US.

Anyone know how long after the US the UK market gets tyres from Michelin?

Here's the URL to the post, take a look through the comments:

Has anyone tried 235 up front?

The wheel is tiny, at only 7.5" wide, and I believe the optimal tyre for that is 225, but just wondering what to do to increase front end grip.

Would the rear 8" wheels fit on the front (in terms of clearance?). Might just swap rear to front and get a set of wider rears.

225/40 are already bigger than the 245/35 rears (on diameter), going to a 235/40 might be a bit much? (2.6%) 235/35 would be a closer match, but they're extremely rare.

If you run rear alloys on the front you'll need a spacer to avoid fouling the strut.

Thanks mp, fair point. I prob would've run 35 profile tyres to keep rolling circumference the same.

Shame the front can't take more than a 7.5" wheel. How strange!

Any idea whether there is more space under the rear fenders?

There's nothing wrong with running a decent quality, hubcentric spacer. Porsche fit them as standard on a few 911's.

I run an 8" front wheel with a smaller offset that stock rear, 18 x 8J ET40 , which fits nicely and allows me to run a 245 square set up.

There's plenty of room at the back, you just need wheels with very large offsets to run wider tyres. What were you considering?

Thanks mp, thanks Hoss.

I was actually hoping to run square also: 245/35 all around.
I wanted more front end grip but didn't want to sacrifice the playability of the rear end, so upsizing the front without change to rear.

I'll have a look at that offset Hoss. Mind if I ask what wheel that is? Also, lowered springs?

What's the rim protector like on the MPS4 (photo?) And any reason why you went MPSS on the rear?

Marco, would you mind confirming whether my thoughts are correct or incorrect please:

- front wheels are 18x7.5 ET45, rear wheels are 18x8 ET52
- reason for the lower offset front is to make sure the thinner 225 tyres are set square to the car (outside of front and rear wheels are aligned instead of more narrow at front).
- if I put the higher offset rear wheels on the front, the inside of the wheel will be 7mm closer to the strut?

So my best bet would be to get a new set of wheels with a low enough offset to avoid fouling the strut all around.

Hi Jahjaman

I'm using GFC AFF-1 wheels in Space Graphite for my VO M135i. I bought the GFCs from Eurodivision in Melbourne. Here's their link: . My car's on Eibach Pro Kit springs. Here's some pics on the Eibachs and GFCs, before I fitted the 245/35s up front: (scroll up for the pics). I like the Eibachs because they are a good compromise for a road car. Not too low and not too stiff.

The ET42 on the GFC wheels allow the 245/35s to clear the front struts and the rear dampers without the need for spacers. My wheel/tyre combo sits nicely within the guards and won't attract undue attention. Spacers are illegal in Oz unless the vehicle manufacturer supplies them, as in the case of Porsche. BMW do not.

Like MP and me, you should like the MPSS 245/35 18 square set-up. The stance on the car looks better, but, more importantly, I found with the 245s on the front, the car feels more balanced overall. Loving it!

No, a rear wheel mounted on the front would be 13mm closer to the front suspension (the offset from centreline + half the difference in wheel width). 7mm + 1/4"

For a square 245/35 set-up, ideally you need
18 x 8" wheels, with an offset ET 35-42.

35 would look quite pokey/aggressive, 42 looks more subtle and OEM. Mine are ET40.

I'll get a photo when I can with the current weather conditions the car hasn't had a wash in a few weeks.

I liked the MPSS tyres and had no reason to switch away from them, the fronts needed to change due to the uneven wear.
