I'm sticking with my 295's lol

Off topic, M2 looks best in Sunset Orange, but you know this.

[ryansandiegoM3]

265 rear. cute. thats my front tire profile

[cwhands]

I didn't have to sign anything when I took delivery of my car (f80) with the 763m and PSC2s.

Interesting.

Why do you feel 275MM VS 265mm? Can you really feel the difference> we talking 10mm difference

[The Automotive Enthusiast]

BMW had a similar waiver for the e46 BMW M3 CSL.

[Anubis80]

I ran cup2s on a focus rs. Heavily modified but even stock the tires, even with AWD, felt scary in the rain.

Great great tire for dry grip but horrible in any other situation.

1. Take delivery with cup2s for warmer months and buy a set of PS4S for the winter. There are a couple of months where the temp will occasionally drop below 32F. 40s and wet will happen.

2. Just get a set of PS4S and use 100% of the time. I'm not buying a second set of wheels.

3. Run the cup2s and accept being careful in cold and/or wet.

As is, I have to be careful in the cold and wet. Mainly wet with my Pirelli p-zeros. Any standing water causes issues. Luckily I can change driving modes for a 50/50 bias front and rear to help. No such option with CS. I'm leaning towards Option 2.

PS4S isn't going to solve your problem in the cold. You shouldn't be using any summer tire below 45 degrees.

[GoneIn4Secs]

Keep the cup2 for the track and run the ps4s on the street,

But they are are both summer tires and if you plan on using the car in the winter consistently, then you need set of winter tires, otherwise good luck getting up your driveway slope on a frosty day!

Yep, trust me, summer tire in lower temperature can become rock hard, with no adhesion, which causes the vehicle to slide, like a lizard on ice - but not in a good way.

A lot of people upgrade to 295s on stock 10" wheels on the F80/F82 platform. I did it myself on my M4 Comp and even going from 285 to 295 was a big improvement in terms of traction. Did not notice any complications at all. If I still had my M2C, I was going to put 265/30 front and 295/30 rear on my 763M wheels once my stock tires are dead. Also, F10 M5 came with 295s on 10" wheels from the factory

Ps4s has pretty much same operating temp as cup 2. Just FYI. I learned the hard way.

The difference is like night and day- Before the car felt like is was riding on top of the tires and the damping was just there to keep thing's smooth. The car is now putting down 26lbs of force per tire after the corner balancing. After having the suspension dialed-in I never see the need to go with wider tires. The car feels so connected wide and flat now that- I feel 265/245 is the perfect fit. I would highly recommend before you go trying to squeeze bigger tires- to get your cars suspension dialed -in first. I can now feel the tires are evenly flat and making full contact with the road. I never see any need to go bigger then what BMW has tested and sized this this car.

Interesting. I'm in VA also. Where did you get this done?

I have run Cup2s on my E92 and F82 cars in California. In the winter they can occasionally be a bit dicey - in the "cold" as well as on a damp road. When it's raining I always needed to be very conservative.

And on a track the shoulders of the Cup2s last for about 20 minutes if you don't have serious negative camber.

In contrast, I find the P4S to be a much better all-rounder. The grip is much better than the regular PSS and the wet performance is streets ahead. Of course, it helps that I'm running 275/30r20 and 295/30r20

[Nikolas]

A waiver is silly. Porsche doesn't require it with their cars that come equipped PSCII. All the GT cars come with them.

Considering they wanted to use the PSS the 275/35 is a worse choice, being just .1" wider, .3" taller, and a pound heavier.

The 285/35 is an even worse choice than the 275, as it's 25.8" tall, the same as the front tire, so you're losing rake, and also creating some minor handling issues that would need tweaking.

I'm going to agree that in the PSS the 295/30 would have been a good rear choice, but for balance the front would have needed to be 265/35, which is .3" taller than the rear, giving you the same rake and inherent handling issues.

With regards to using the PSS, they chose the overall best sizes.

No Summer tire does, that's why they call them Summer tires. It's only the guys that try to use Summer tires as All Season tires that have issues.

But it's certainly possible since they have the 19/20 763M from the M3/M4 CS.

And this is because of the 30-series sidewall that is the same height as stock. There is more lateral movement (taking a set will take a fraction of a second longer), but it's so minimal that one would not notice.

This would literally depends on the make/model of the tire you choose.

[bjcarls]

I'm pretty sure I had to sign a waiver when I purchased a 2005 545 with summer tires. Either that or it was a 2001 Audi with summer tires. This is not uncommon.

And I would argue that PS4's at 35 degree's, dry roads, in south with stronger sun will brake and handle better than snow tires at 35 degrees. The one true kryptonite is snow, ice and freezing. The rubber on a summer tire will turn rock hard.

I'm not surprised. This is the US after all, people sue for coffee being hot

PLEASE tell us you're joking.

Paraphrasing—- it gets cold here so I'll switch to MPSS4's for the winters.


Result- Hey guys, I slid off the road in cold weather and nailed a father and his kid walking down the sidewalk ...but I had my winter PS4's on can somebody explain why?

I run 265/35s front and 285/35s rear. Works fine (not OEM wheels).

It rarely drops below 10°C (50°F) in winter here but even still my Cup2s are essentially gripless when cold. Once warm, however, they are significantly better than the original MPSSs in terms of dry grip. I do more track kms than road so for me, with camber plates, the Cup2s are an easy choice. The outer edge of the tyre wall apparently has reinforcement and they actually last MUCH longer on track than MPSS.

I think the comments on this thread about excessive Cup2 track wear refer to standard camber cars combined with over-driving. From what I have seen of other cars at track days a driving style that is excessively late on brakes and basically force the car around the corner unbalanced leaves massive tyre wear. An Alfa Guilia QV at a Phillip Island track day last year got only 2 sessions (40 minutes!) out of brand new P-Zeros before hitting canvas- I followed him a few corners and he was really chucking the car around then correcting and re-correcting with massive understeer. Had the bloke slowed down more and balanced the car before turning in he would have been faster overall and his tyres would have lasted a few track days. These are the blokes that then complain their tyres are shit...

I'm with other comments here - Cup2s for track and Pilot Sport 4S for road. Cup2s definitely not for a daily driver. And at $2200AUD a set for my size Cup2s, fitment of camber plates will absolutely be your best investment as they extend track day longevity by 2 or 3 times. The camber plates pay for themselves after 6 months of regular track days.

PLEASE share your experience with us. I've spent 3 winters with summer tires on my underpowered civic. I'm always interested in the personal experiences that others share.

Easy you're being blatantly irresponsible.

In the unfortunate event that you are involved in an accident on summer tires during temperatures or conditions they are clearly not designed for I hope you're held accountable as being negligent.

Summer tires are always noted by their manufacturers in regards to their operating temperature.

A personal experience, don't worry I didn't forget about that.

A tractor-trailer ran a red light in front (perpendicular) of me when I was on my MPSS's... even with all The safety features of my M235 (back in 2014) it did not allow me to stop in time. I was about 2 feet too long in stopping. It was an early cold snap in September... unusual for the area I was in.


Had I had my winter tires on I would've stopped in plenty of time.


They are called SUMMER tires for a reason.
