It seems that they guy at Tyre Reviews chose an M2 to test the new summer tires. So we just got a nice custom tire review just for us

I was 100% to pick up a Michelin 4s for my next tire, but after seeing this and considering I live in rainy Belgium I might consider the Good Year.

Unfortunately no Michelin Pilot Sport Cup2 as reference, no Pirelli, Bridgestone, Dunlop...

Good idea to add the accompanying article.

I do like his videos, but maybe it's a matter of personal taste

A Cup2 tire would've made 0 sense among those tires, it's a different class of tire

And really? The logistics of a comparison like this are insane, testing all those tires back to back on a state of the art testing track literally designed to test tires is a huge feat. And we got lucky for us that they used our car an M2.

Guess you just cannot satisfy some people.

[vale007]

true, not satisfied, for me it is very unfortunate that the cup2 is missing, i choosed this over the PS4S and it would be interesting to see if it’s worth to run the cup2s or if the normal performance tire is very close in dry handling already.. for me the cup2s really feel like normal road tires, with less profile on it and a very high price..... i hope that there is a semi slick review upcoming, with a normal high performance as reverence, as it was promised by tyrereview a few months ago..to compare semis as well!

This guy does the cup 2s in another video. Says they are performance monsters in the dry when at temp but cool fast not going to get their usefulness from general road driving.

as it was mentioned above, they do have a Cup2 vs PS4s review:

IMO unless you live in a very low precipitation area I would not use the Cup2 on a daily driver, as with most semi slick track tires they are quite bad in the rain

In this Dimension ok, after there this so much standing available, which you do not find very often, true?

Michelin Semi slicks are dangerous in the wet? 10years ago maybe - today, not really! please compare the negative profile of Michelin cup 1st gen, Michelin cup+ and Michelin cup2*. The only Michelin which is not useable at wet conditions is the cup2R or cup2ZP corvette semi slick.

In 245/35/19 - 265/35/19 for the Michelin Pilot Sport Cup2s * this is not true that there is very bad handling in the wet, they are very different from the 1st generation Michelin PS Cup! (Which makes me think to switch to pirelli trofeo R)

Cup2* are even better in damp and light wet as the oem Michelin PSS, also in the wet if there is enough profile left and no big aquaplaning risk. we tested this even in the rain (wet, light wet, damp) on mountain roads, one M2comp on PSC2* the other on PSS.

It was dangerous to follow the PSC2* car with the PSS, there was more understeer and even turn in oversteer at same speeds which was not that predictable at the oem PSS M2c!

Also the noise comfort of the Cup2* is very good..

Subbing to thread because I need really good laughs. I'll just reply with a huge post to help fix everyone's imagination around tire rack "tests" lolololololol

You start complaining that there is no PS4 vs Cup2 comparison, I post that comparison for you. Now you start talking how the Cup2 is better than other tires.

It's clear that you want the Cup2 tire and you are grasping at justifications. Buy a Cup2 tire if you really want one, no law against it.

For me, living in a country where it rains regularly I am not willing to trade a lot of wet performance for a smaller gain in dry performance. For a daily driver that is. (you lose vs PS4 - 5m of braking and 3 seconds a lap in the wet vs gaining less than a meter and a less than a second in the dry)

Yeah, the actual dry performance difference between the PS4S and PSC2 is small. In that example above, the PSC2 was worth 0.45 seconds quicker time on a 1:16 long circuit lap. However, in the wet it gave up 3 full seconds to the PS4S and also in wet braking the PSC2 took 14% longer to stop.

The cup tire performance difference in the dry is the closest it's ever been to the top of the line "normal" tire versus anytime in the past (i.e. PS4S vs PSC2 now compared to PS2 vs PSC 14 years ago).

Grassroots Motorsports just published a test of the highest performing, no compromise, dry tires (i.e. the SCCA cheater tires all molded with 7/32 tread depth and TW200 ratings to meet SCCA street class rules). If anyone wants the ultimate level of dry grip (and also very good wet performance due to soft compounds), these three tires are very closely matched: BFG RivalS 1.5; Bridgestone RE-71R; Yokohama A052 (2019 revised version). All three of these substantially outperform the PSC2 on course. Of course Michelin makes the BFG RivalS.

It would appear Michelin is aware that the PSC2 needs help since the PSC2R is beginning to appear.

i understood that the cup2 on a Ford Focus ST (184kW/250Hp) are 5% slower in the heavy wet.. 230i coupe comes with 184kW/250hp, right?

the ford focus have no traction issue to solve from high amounts of power or torque at all, that’s why the (dry) handling time is that close imo.

i‘m only curious how close it is within the bmw dimension, if it is worth running cup2* or switch to PS4S(or pirelli or other) after PSS..traction wise the cup2* have no issues with even 550hp/750nm when warm..

@CSBM5

i‘m sorry i found no Yokohama A052 in BMW Dimension, there is no 18“ or 19“ for the rear.. which size US meant? also no BFG rival s 1.5s.. i‘m afraid the Bridgestone is not available in Europe..

I wasn't specifically referring to the M2 fitment. Here in the US, the top contenders use 275/35-18 all around on the 9" and 10" wheels for the original M2 in either the RE-71R or the RivalS 1.5. On the M2C, it comes down to the RE-71R in 255/35-19 and 275/35-19 although some are using the 285/35-19. Some have also fitted the 265/35-19 up front (minor rubbing) and 305/30-19 in the rear. It's what works in SCCA street class....

Seriously though for all-around street use, none of these cheater TW200 tires are really viable imo. I have an extra set of wheels and RE-71Rs for my M3 for autocross, and driving those on the street results in lots of road noise (tire engineer speak would call it "sizzle" over road markings too), very stiff over bumps, rapid wear, etc. Hence the point of the post was simply to point out the best, no-compromise streetable tires that exist today.

[vale007]

ok thanks for info; in Central Europe we need to get the dimensions in the car documents/papers, only max. 255/35/19 and 285/30/19 possible I think.

i consider michelin 24/65-19 slicks for trackdays.. if so i‘ll post some pictures! they come as approx. 270-275mm width on 9/10 oem rims.. which should allow me to run low camber (2 - 2.5degrees max) alignment as it should work with the Pilot Sport Cup2* for street use aswell .. hopefully

I was trying to find a fresh review of Pirelli P Zero tires. Couldn't find one. Wonder how they stack up against the other brands' new offerings. I used to run Pirelli P Zero tires on other cars (including m235i) and really liked them. It's been a couple of years, though.

[vale007]

there are even brand new pirelli corsa‘s on the market! ac-schnitzer run the 20“ dimension, which would be available for the m2, 255/30/20 square.. ac schnitzer use conti‘s i guess

[eeyang92]

In my experience running PS4S, they are an extremely solid street/track tire. Approaching 15k miles on my set and 2 tracks days since installation and they still have a lot of tread left.

I wonder how the treadwear on the goodyear and continentals stack up to the PS4S. My first set of continentals that came with the car only lasted 10k miles with 1 track day on it (although I may have swapped it early since I didn't like the lack of grip).

OMG, that test track looks like fun, I wish I could rent it.

[SpartanGA]

I hoped for Hankook to compare.

also I’d like to somehow have a wear comparison.
