The 235/35-19 on a 8" rims & the 255/30-19 on a 8.5" rims is not a fare comparison.

I think the 8.5 rims would suit a 245 tyre tbh.

both are on a 8.5j rim in the pic

The tyre side wall in the right hand pic looks like a doughnut (curved surface) before it meets the rim. Can't be good for the tyre performance as any hard cornering must roll over onto the side wall.

Tbh i can't see what all the fuss is about how the tyre looks on the rim if that's the recommend tyre fitterment by that manufacturer on them rim sizes.

Michelin have been manufacturing tyres which over the years have won major championships in all forms of motorsport inc motorcycles so what do we really know about it.?

So..... a bit of an update on the Michelin's I fitted to my car in place of the OEM Pirelli's.

Once the tyres were fully scrubbed in I have to say that the grip in dry or wet conditions is in a different league to the Pirelli's. You would have to drive the car at a totally insane speed on a public road to induce any significant levels of understeer when compared to the Pirelli's.
But it's not all good news. Now that I have covered around a 1000 miles with the Michelin's I have noticed a strange tendency for the car to wander or tramline slightly on some road surfaces, almost as if the car was being driven in a crosswind and an occasional gust would need steering corrections to counter it to maintain direction. Then there is the harsh ride which is not helped by the increased tyre pressures to counteract the traction control issue. I would only use Dynamic mode on very smooth roads as it was just too bone hard on any other surface.
I have attributed this to the 255 section tyres fitted to the front. As mentioned in earlier posts in this thread, the 255 Michelin is a fair bit wider and has a much more square shoulder than the equivalent sized Pirelli, I have also never been completely happy about the bulged look of the sidewall of the 255 Michelin when fitted to the front 8.5J alloy. It's as if it's squeezed onto the alloy.
So I have now fitted the 235 sized Michelin's (but 35 profile) to the front which is now the 'square' setup that some owners have on their cars. The tyre now appears to sit properly on the rim without any bulged sidewall and the ride comfort has been improved to where I can actually drive around in Dynamic mode again without smashing my spine to hell. No surprise that grip is slightly less than with the 255 section tyre (but still better than the OEM Pirelli) and the turn in is not quite as sharp but so far I have had no issues with traction control or the strange random wandering or tramlining. Overall, this seems to be the better setup for my car (I have Eibach Pro springs fitted too).

....and the 235/35 Michelin. The side wall looks much better and has a higher profile (35 versus 30)

Interesting read this.

I too have the staggered 8.5 (front) 255/30 8.0 (rear) 235/35 Pirelli’s

I’m lowered on h&r including mag ride re calibration, I’d be interested to see if this mps4 setup works to soften the ride further with the square tyres?

And improve the handling.

Interested. I tried the 245/30 Michelin’s on front (235 on rear) and still had all those issues listed above. I’ve just went back to the standard RO2’s as couldn’t be bothered will all the issues again. Hopefully the 235/35/19 all road works

I think the 30 profile tyre is the issue. They look fine for that mean lowered look, and the narrower sidewall provides amazing turn in and grip, but the downside of the Michelins is a harsher ride with a tendency to tramline (I ran them at 42 to 44psi at the front to quell the TC issues). Also with the 30 profile there's the risk of contact with the dreaded pot holes on our UK roads.

The 235/35/19 Michelin I am running at the front (42psi) seems to suit my car setup just fine and in my opinion offer better allround performance than the Pirelli's.

I think I’ll try the same route as you once these wear out (about 4K miles no doubt) or will had a pot hole over the next couple months

It's interesting hearing these complaints about the Michelins as the RS3 runs the same tyre setup as my old C63, albeit backwards  :lol:

My C63 came on Continental Contact Sport 6's and the wear rate was shockingly bad.

Switched to P4S's all round and was superb, grip on another level and wear rate dramatically improved.

I managed 18 months on a set of rears before I sold the car with still plenty left as opposed to 6 months for a set of Conti rears....

 

I haven't been that impressed with the standard Pirelli setup, especially in the wet the front wants to wander more than it should, and I was hoping to go to Michelins but this concerns me somewhat.

Anybody evaluated MPSS Vs P4S's?  Might be a good middle ground.  Trouble with the 255/30 profile is it's always going to be a stretch and very thin, but many say to inflate the Michelin more IIRC having read a few more posts on this.  There's another thread on this somewhere where someone was saying it much improved after increasing pressures marginally.  See if I can find it.

Fivepotfan fitted MPS4s to his FL & the 255s looked over size on the rim compared to the stretched looking oem P zeros.

He found that by increasing the tyre pressures a small amount it seemed to cure the traction light issue.

I had traction issues with mine as you know Dell ;) I just turned off TC which stopped it. Another button press for the "startup procedure" !

I have been running the 235/35 section MPS4S on the front 8.5J alloys for a few weeks now and have to say that I am very happy with the ride comfort, handling and overall grip. I have also not experienced any traction control issues at all other than the 500+ps overwhelming the tyre grip when really nailing the throttle.

What has really impressed me with the MPS4S is the levels of grip over the Pirelli's in all conditions, I didn't expect them to be that good in the wet or cold temperatures but they have surprised me and have out performed the RO2's that I took off the car.

On the dinosaur 8Ps we don't have all these tec/push buttons options & neither do we have traction light issues with MPS4s 😂 which as Fivepotfan stated are a great all round in all conditions tyre.👍

Maybe once these Pirelli’s wear down I’ll try the PS4S 235 all round

Now that I have tried the various options of different tyres brands and different sizes and profiles...…..if I had a clean sheet and started again I would probably fit 245/35/19's Michelin MPS4S all round (preferably on a set of 8.5J REVO RV019 alloys). In my opinion these would offer a decent level of ride comfort but also give good grip and least amount of hassle with the traction control.

Unfortunately I don't print my own cash so the 235's all round is a good option and works well on my car (it has the Eibach Pro lowering springs)

 

Pic below is the REVO RV019 8.5J alloy and 245/35 tyre combo I spotted on a saloon. Looks just right with the sidewall not bulged so it actually allows the tyre to work properly (ride comfort as well as grip)

I had the 245 front 235 rear and it was awful. But it seems to be the staggered that cause it so hopefully as you say 245 all round would work fine

Makes sense, the smaller front wheel width is the main difference.
The C63 runs a staggered setup with a 9" wide rear wheel as opposed to the 8.5" on the front of the RS3 which would explain the bulge you're talking about.
245/30 might be a good compromise, but doesn't look like many suppliers have em in that fitment unless you go to the likes of oponeo or tyreleader. I wonder whether MPSS might be slightly more narrow in the 255 fitment, really would depend on the makeup of the tyre.

If it's as bad as you say it almost sounds like it'd be worth going 225/35 and 245/30.

If the fronts at 8.5" look dwarfed by a 255 wide tyre I'd imagine an 8" tyre will have similar issues with a 245 width at the rear.

Or is your setup not staggered?
