Hi, looking into getting some semi slick tyres for my m140i to handle the extra power, would I be able to run semi slicks on the rear only or would this not be a smart idea?

Just get decent tyres all round and you will be fine. If you are feeling the need for something racey, Yoko A052s are amazing, legal, and b rated for wet grip
I’ve got 2 sets of wheels so was thinking having 1 set normal road tyres and the other semi slicks and can change them on the drive depending on weather. Would you just recommend to get 4 slicks the same?😂Just get decent tyres all round and you will be fine.

and ice. The OP's suggestion is the opposite of what people usually do approaching winter.Apart from track days, it isn't usually done in the summer either because they tend to wear out quickly

Yes. It might be the case that super sticky on the rear only would be good but you'd have to look into it in detail: tyre pressures, spring rates, damper settings, wheel alignment angles, etc.. A lot easier just to have a full set of each type of tyre.White-Noise said:
I have 2 sets as well. Really the car is for track use but I use it on the road. I generally leave the Michelin pilots on it unless it's going on track and it's going to be largely dry. The semis are ns2r's. They cope with a bit of damp but I wouldn't risk anything more.
Perfect thanks for the help, I was looking at the nankangs too I think they’re what I’d go with, many thanks again!Pachydermus said:
if you're pushing the grip limits of normal road tyres on a public road you're soon going to find yourself in a world of pain in multiple ways. Someone should point this muppet in the direction of the 10ps thread.
Never said anything about public roads you helmet thanks for the informative input thoughjmorton1627 said:

This makes a bit more sense. I used Yokohama A048's and Toyo 888's on the road and track for a while but the car was only used occasionally on road, basically for driving too and from tracks. Thats not to say it didnt manage a 200 mile round trip across Cornwall in January ice and snow. Once.If you have two sets of wheels then it would make sense to have one set with some decent road tyres. Don't even think about mixing semi slicks and road tyres. Semi slicks are not about traction or grip on the road. You wouldnt even get them up to temp.
I have a set of NS2Rs on my Fiesta ST as I used it for a track day last week, when I get time the PS5s are going back on, have two sets of wheels.
Tyres like that need heat in them to grip, they are by and large worse in daily use than the Michelins, they aren’t a ticket to extra traction all the time. A decent road tyre will outperform them most of the time, you can’t, most of the time generate enough load to put heat into them on the road unless it’s really warm.
For an M140i, if you haven’t got an LSD, maybe spend the money on that. Main problem is more power than they can really cope with as standard, never mind the ones with 500 bhp plus on tired suspension which was hopeless when new anyway, I had an M135i for three years.
So add in cold, wet roads, usually an auto box, wooly steering, wobbly suspension and masses of power you will of course struggle for grip, the rears aren’t that wide and the car isn’t all that heavy, plus it’s fairly short.
Semi slicks arent the answer, unless the question is drag racing with a decent burnout beforehand, x drive conversion or get something with 4WD.

This will only work if you fold the rear seats down permanently, which, according to a similarly-challenged poster many years ago, actually reduces the weight of the car.Bonus is you also get to drive a 2 seater BMW for nothing.
