Sean.

I believe the manufacturers are allowed to make there tyres size within a certain percentage of true value.

Dell.

Yes I agree Dell

However it’s interesting how Michelin choose to increase tread with by a fair bit

No wonder people rave about how they ‘transform’ the cars handling.

20-40 mm more is a big increase on a footprint.

The 235 vs 255 above proves there is little difference in tread width on 2 different widths.

I always use to use Eagle F1 asymmetric 2 on the A3 & S3 and never had any issues either. If Michelin’s lowered their standards I’ll jump straight back to these again although I know they have the asymmetric 3s now, so would try those.

[RS3Dell]

So the question is........
Are Pirelli producing a narrower spec tyre ? And if so why ?
Are Michelin producing an over sized spec tyre (ie more tread) to make sure it out performs all the other brands......

Sean.

Going by your measurements & photos the MPSS are nearer there spec sizes,were the Pirelli are well undersize.

The Pirelli seem to be so undersize that they really don't sit the same as the Michelin on the rim as they look stretched,were the Michelin sit square on the rim & look over size due to there correct seizing.

Never had a moments problem with my Pirellis on the Barge and now the RS.

 

I find it hard that if some one drove 3 cars all with premium tyres on them that anyone would know whats tyres were on the cars !

 

Personally I think its all a bit of the Emperors  clothes situation !

 

Or im just not driving fast enough.

 

Audi spend £££££'s on research surely they put the best tyre on for each car ?

[RS3Dell]

Come to think about it every car ive seen with Michelin sport tyres on there sidewalls all look the same as they do on mine.

Not if the bean-counters have their say and they can save a few Euros per car! My last PFL didn't even have interior lighting as standard FFS!!! Some cars even leave the factory without being properly painted with a colour

Which is why you’d be better off with flung-dung tyres.

Cheaper the better.

I didnt say that did I !

 

When did I say cheaper is better ?

Thats a great bit of ferreting about on the web 👍 Now that make sense after lasts weeks posting about Pirelli v MPS4s & the traction light issue.

I don't have a PFL/FL but if i did & how I've l found the MPS4s on the 8P I'll still fit them in a blink of an eye there that good ! 😁

But not Chutney Ferreting Dell

Was in 2 minds about the MPS4S and now I may go with something else.....maybe Goodyear Eagle F1 assy 3’s like I had on my PFL.

😂 About the ferreting 😂

Sometimes its best sticking with something you've tryed & tested mate.👍

I do like to try something different..... variety is the spice of life 🤣

I've gone from the factory fitted Michelins to off the radar Avons which have worked beyond my expectations in more ways than one on the MTO7 bike.😁

[nardo rs3]

Had mps4 fitted alround last week,just done 1500 miles to Germany and back, good mix of weather conditions and no problems with traction.

[Fivepotfan]

Bit of an update now I have had the Michelin's on the car for a few hundred miles.

I noticed that some owners were saying that they run their MPS4S's at higher pressures and were reporting no issues with the flashing traction control. I tried inflating my tyres to 44psi front and 39psi rear and so far I have not had the TC problem re-occur. Ride quality is a bit harsher and there is a little more road noise too. With the tyres now being more scrubbed in, I would say that there is improved grip (not surprising given the extra rubber over the similar sized Pirelli) and the turn in feels sharper. I have also tried them in the wet and can report that in my opinion the Michelin's understeer less than the Pirelli's.

Since fitting the Michelin's the handling characteristics of the car have changed slightly and I am having to re-learn the adhesion limits and at what point the car will 'break loose'.

Very interesting topic been started here. a lot of this has been discussed before but not as much detail as here.

 

When I was at 2000 miles I hit a pothole and got a puncture on the front and as I always planned on changing to Michelins as I had Pirelli P-zeros on my last car and knew the were very soft.. I got it changed for a Michelin PS4S 255/30/19. So I had one Michelin and one Pirelli on the front. I did used to get the traction light flicker up on the odd occasion. I had also just got the MRC remap at this time so I thought it could have been that but in my head I knew it was the Michelin.

 

I then got new wheels a couple thousand miles later and as use know the p-zero is a lot more stretch where as the Michelin was more square. Because of this the Michelin now rubbed when I was on hard lock on the inside of the inner arch. It was not bad and I tried to file it down a bit but didn't seem to make it any better. Now at 9000 miles I needed to change the other front tire as I could see it getting low [other front P-zero]. So rather than having 2 Michelins that rubbed and didn't want to get 2 P-Zeros that last 9000 miles I decided to opt for Michelin PS4S 245/30/19 on the front. I was not sure if they would fit without rubbing so I decided to get 2 part worn ones with 5mm tread to test the fitting first. I had read somewhere online that due to the Michelins being a lot more square the 235 Michelins are as wide as the 255 Pirellis which the pictures posted above seem to prove. The pirreli I removed had cord showing all the way around on the inside which I think is absolutely shocking after only 9000 miles. Another reason why I didn't want them on my car.

 

I now can confirm they fit perfectly. No rubbing on hard lock like before and even though ive went down a tyre size they still have a wider tread in contact with the ground. Unfortunately now with 2 Michelins fitted to the front [still 235 P-Zeros on rear] the traction control flicker light is really bad so always has to be switched off. Ill try what everyone is saying on here and try higher pressures, currently I run 35psi rear and 39psi front to see if it helps a bit.

 

As im on it im wondering if the 245s will fit on the rear so I run a 245 square set up. Which in turn means wider tyres on rear will also give me better grip. At least I can swap the wheels around to see if they fit rather than having to fit new tyres to test.

[billymc92]

@drgav2005 I also had rubbing on ispiris and now changed to 245 front with no issues

[billymc92]

Michelin 255


Pirelli 255 [although this looks like 260mm if you measure the tread that only contacts the ground and not the rim protector on either side its only around 230mm[


And a few side by side shots. You can see how badly the inner of the P-Zero has worn after 9000 miles

Are you running standard ride height all round around if not how low are you running ?

No I’m lowered around 20/25mm. But I had this situation of rubbing before I lowered but when I lowered it did not get any worse. It just stayed the same
