oh, i wouldn't know...my go to sets are the MPS4S :O
Does it not annoy you with the 4S the promoted oversteer, I get it, but like if I'm buying a tyre of that price i.e. the T005 price range, I don't want the back end breaking free even in an amusing controllable way, unless I make it do it, I was a drifter for years, and yes that's cool but you don't want that from normal or fast road use/smashing a windy set of national limit bends... Was a bit annoyed they do that?
I think if I got a Michilen it'd be a PS5, but I just cant bring myself to use them due to hating a soft sidewall tyre and rollover. But everyone is different and drives their own way I guess... I can easily get over the lifespan being shorter but I wont sacrafise handling/sidewall when it's in that price range, I'm sure you understand.
It sucks as some of the best older model tyres I've ran were Michilen, and ofcourse they don't make them anymore
I love Advans and Potenza's, but they're only good in the summer/dry, I like a tyre that does it all, but it's very hard to find a rain tyre that isn't a silly soft compound/flexy/squashy sidewall/prone understeer regardless of the drivetrain, the PS4 will do it on fwd/rwd and awd. It really annoys me. Yes it allows you to save some spicy moments and recover and bring it back, but aside from that it just ruins all the money I spend dialing in my alignment/all the work/parts/mods I've done to the handling of the car
And as I'm sure you know, a lot of amazing dry grip tyres are genuinely lethal in the wet, let alone with a quick car... And when you get silly things like understeer with a PS4, it really annoys me. Merc's love to understeer as standard, as they're more autobahn stormers/german muscle cars vs being say a ///M car, and yeah that annoys me, so imagine having that happen on a premium tyre yet everyone bangs on about them online like they're the best, I reckon 90% of it is people just being embarassed they're not as good in reality and just flexxing on the fact they buy such expensive tyres and just reshare misinformation.
I'd be fuming if I bought a PS4, paid to have them fitted/balanced, then went out and experienced that/risked a crash, not like you can return them, then you're stupid money into it/wasted and have to continue to use them.
So I'm glad I didn't find out the hard way. I couldn't believe it when my mates mustang did it though, being rwd, the last thing you expect is the front end washing out like a fwd...
They make old school rwd Porsches tram line too...
E36's from factory have slight promoted understeer, but it's easily fixed by adding negative toe to the front end and then they handle amazing.
