**Unofficial Tyre Thread**

I found no difference in ride comfort between the two. But you could really feel the roll more in the F1s
 
That makes no sense, if the sidewall is sufficiently softer to encourage more body roll it must surely follow that it will have a slight effect on comfort too?

I can't see there being a huge difference anyway on a 35 profile tyre. Never noticed a difference in body roll when I moved from CS3 to F1A2 on the 530i.

What's the best way of storing tyres?
On rims or not on rims?

Just curious whether to stick my summers on new alloys over the winter or just leave the alloys in the box until spring.
 
How annoying, getting annoying road noise from my front F1A2's. Sort of an annoying resonating sound. On totally smooth surfaces it's silent but less than smooth ones it's there. Never had this with Eagle F1's before.

My sister just had to ditch four F1s off her S3 after 5k as it sounded like the wheels bearings had gone the noise was gradually getting nosier with miles, wheel alignment was spot on when checked. I assume the wheel alignment settings have something to do with how the F1s wear which can result in more road noise, I had a similar issue when my rear wheel alignment was out.

She has swapped to Continental 5s and they are so far very quiet.
 
Never had a problem with F1A2's in the past, noise levels seemed the same as CS5's to me.

Perhaps its a rim size / profile issue?

Might be worth seeing if +/- a few PSI sorts it out.
 
Yea, the F1A2 is normally praised for its low noise and I've never been anything but thoroughly satisfied before, hence why I picked them. It was right from 0 miles, too. I've only done about 50 miles on them so far. Perhaps it'll go away.

A shame because in every other respects my car is better, it is smoother, it grips better.. it's just a better car.
 
Supersports back on the 911.

Brand new on the rear, fronts are still the original 10 track days plus 10,000 miles with still a plentiful 5mm-6mm tread on them. :eek:

On the Pirelli Corsa's I could not go near the throttle in damp/wet conditions, no matter how much heat I got into them, the car would be sideways without much warning and very quickly with smallest squeezes of throttle. They actually felt like driving on grease/ice in the wet conditions and made the car very nervous, in the dry they were literally untouchable once warmed up.

The Supersports have 90% of their dry grip, but come these damp/wet conditions I can floor in 1st gear with little to no wheelspin, whereas the Corsa's would start spinning up in 3rd once past 5500rpm. The communication in wet/damp conditions on the Supersports is in a different league, the confidence I have in the car in such conditions is immense and the way it can cover ground on those tyres in the wet is rather mind boggling.

I've had cups, corsa's, PS2's, Pirelli Rosso's, Pirelli Pzero's, Bridgestone RE050A and F1AS2 on 911's/Boxsters and I can say nothing comes close to the MPSS as an all round performance/safe tyre on a Porsche, it really does stand above the others by far. The closest for wet grip and I'd rate as good was the F1AS2 but they did not inspire the same levels of confidence like the MPSS do. All the other tyres in the wet were just average or shocking. In the dry the cups and Corsa's once heated up were amazing, the Corsa's more so, but they did need some heat into them to really work. Whereas the SuperSports work right away and when warm grip practically as well on track and are better on road and compared to the other normal road tyres the MPSS is in a different league in the dry on the road.

Michelin oh why do you not sell them in 265/35/18 in the EU/UK market. :(

I'd rate them as such:-

Dry Conditions on track
1. Pirelli Corsa
2. Michelin cups
3. Michelin Supersports
4. Michelin PS2's (though they wore very quick, 2mm in one track day, compared to 0.5mm on MPSS, same driving style)

The others I cannot comment on track as never drove on track.

Wet Conditions on track
1. Michelin Supersports
2. Michelin cups
3. Michelin PS2's
4. Pirelli Corsas

Dry conditions on road
1. Michelin MPSS
2. Michelin PS2
3. Pirelli Pzero
4. Goodyear F1AS2
5. Michelin cup
6. Bridgestone RE050A
7. Pirelli Corsa
8. Pirelli Rosso

Wet Conditions on road
1. Michelin MPSS
2. Goodyear F1AS2
3. Pirelli Pzero
4. Michelin PS2
5. Bridgestone RE050A
6. Michelin cup
7. Pirelli Rosso
8. Pirelli Corsa

Subjective feel - Dry
1. Pirelli Corsa
2. Michelin MPSS
3. Michelin cup
4. Michelin PS2
5. Pirelli Pzero
6. Goodyear F1AS2
7. Bridgestone RE050A
8. Pirelli Rosso

Subjective feel: Wet
1. Michelin MPSS
2. Goodyear F1AS2
3. Pirelli Pzero
4. Michelin PS2
5. Bridgestone RE050A
6. Michelin cup
7. Pirelli Rosso
8. Pirelli Corsa


So any Porsche owners here, those the tyres I've had on mine or other Porsches borrowed from dealerships. The MPSS as a road tyre on any Porsche is pretty much untouchable. The weakness as mentioned here is the ride quality could be better and road noise levels lower. But do 911/Boxster owners care about such things? THESE ARE SPORTS CARS!

Just tried this, made no difference. Great :rolleyes:

The rest of the car is so quiet now it's really annoying :rolleyes:

Why is everything to do with cars crap? In any other industry if you buy something and it doesn't function correctly you can have another one. With tyres you must put up with it for the next 40,000 miles.

Maybe because they are brand new so more block movement, see if it calms down after 500 miles, just make sure you don't think its gone because you got used to it.

Record the noise now and then re-record the noise 500 miles later, same road, same conditions to see if suitable noise drop has occurred.

Last but not lease maybe try nitrogen instead of air?
 
Is there anywhere in the UK/Eu that stocks MPSS for 245/40/17. Will Need new tyres on the back of the slk soon, I noticed the yanks have this size and it's listed on the Michelin website, but have looked to no avail.

Proper rubbish how some popular sizes are not available in UK/EU yet are in USA.

265/35/18 is what I need, don't want to go with 255/40/18 to be honest.
 
To be fair, I would love to get some Amg style alloys on the Slk in 18", which would get the correct sizes anyway for the MPSS.

But, just purchased a house, so expensive mods are on the backburner for the time being :rolleyes:
 
Drove past KwikFit earlier, pretty sure i seen a sign saying 25% all Pirelli tyres when 4 bought.

Can't find anything on the internets about it though? Anyone else seen this? Know anything?

Its typical rubbish, they were doing the same thing on Goodyear when I went in once, the starting price is so high that even with 25% off it's still comedy expensive.
 
Im going to buy some F1 AS2 next week for my 330i.

price from blackcircles.com is :

2 x front 225/40 R18 Y £265
2 x rear 255/40 R18 Y £305

total £569 delivered only. I can get my uncles garage to fit.

Anyone got any where cheaper to buy from?
