I didn't say 295 would be better for street and not track What I said was 295 PSS or PS4S on stock wheels are definitely an improvement over stock PSS 265s; however, there are couple reasons why you may not want to run this on a track especially if you have prior track experience. For example, 295s on a 10.5" wide wheel will give you better effective contact patch or traction compared to 295s on 10" wide wheels (stock wheels) because tire will be sitting better on the wider vs the slightly squeezed fitment on narrower wheel. This matters on a track and can make difference in terms of grip. Another reason why I wouldn't run 295 PSS/PS4S on a track is that they are too soft and get overheated easily. You can easily destroy the shoulders of these tires on track if you are pushing it. I prefer R-compund tires (such as Nitto NT01) for track duty since they provide much better grip, have amazing durability and they pretty much don't heat-cycled out easily. However, since you have no prior experience, I would highly recommend you to take your car to your first track day as is, without any track wheels or tires. PSS or PS4S will be more than enough for at least first couple track days and you'll learn and progress much quicker on street tires.

The reason I'm obsessed with wider street tires is that I'll be getting the CS tune after my break in and putting all that power down on stock 265 tires is just near impossible at lower gears. If you want to play it safe, you can also go with 255/35/19 front and 275/35/19.

The 265/ 295 combo is definitely doable but the 295 like others have said is pretty wide on a 10 inch rear.

255/35 and 285/30 would be ideal IMO, but Michelin does not make a PS4S in 285/30. I don't think a 285/35 would work.

So, I think I will go 255/275 as a fairly conservative choice, unless a new tire on par with the PS4S pops up in the next few months.

I think after I run my PSS down I will try the ps4s 295 rear 265 front, my only concern is whether the 295 is safe and gonna cause issues for me, I do lots of road trips states away etc, do you think I'd see any issues day to day usage?

As I said, I ran 295s for 2 years on the M4 which has the same 10" wide wheels and I know a ton of M3/M4 owners who are running 295s on stock wheels too. I did 20k miles on them (highway, city driving as well as couple track days when it was raining) and never had any problems. 295 on 10" inch wheel is still within the range of the wheel. It's not like you are trying to fit 305s on a 10" wheel which is out of spec and not recommended but I have seen people who did that craziness too.

Edit: Check out the F80 forum wheel/tire section. You'll see many people are running 295s on 10" stock wheels.

Be a baller and just get the 763 set with pilot sport cups the way they come from BMW.

I assume a 285/35 won't work on the rear of the m2C?

[FSU_Logan]

295 ftw

I ran 305 on a 10" for like 7 years lol but 295 seems to be the favorite for this specific platform and oem offset

Yup and BMW F10 M5 came fitted with 295's on 10" wide rear alloys from the factory so need to worry

Good sir,

Beyond better traction, do the wider tires affect ride quality in any way? Would love to hear your thoughts. Thank you!

Yes, slightly more road noise and a bit more harsh ride quality if you go with a shorter sidewall (e.g. 265/35/19 to 295/30/19) I'm used to the 30 sidewall from my M4 so it won't bother me but it's definitely something to consider. I would choose better traction over comfort anytime (I'm probably in the minority tho... )

I have one last event and I'll be selling the tires next spring to replace them for something else be it PS4S, S007A or maybe AD08R.

If they have your size Hankook RS4. Almost as fast as RE71R but lasts 2X as long, very resistant to overheating and pretty cheap. If R comp NT01, if full slick Pirelli DH.

Thank you!

You know, I was VERY surprised at how comfortable the ride is on the M2C. After reading all the reviews and watching all the YouTube videos on offer, I was expecting my teeth to be rattled loose. Instead, the car really feels quite comfortable to me.

So, I think the trade off you're proposing makes perfect sense. Will definitely be doing 295/30/19 and 265/30/19 when it comes time to replace tires.

Thank you so much for the insight!

One final question: Where do you typically get your tires from? Tirerack? I know the lazy thing to do is simply have the dealership order and mount, but wondering if all the cool kids know of a better way.

Thank you again.

Glad I was able to help

Dealer would be probably the last place I would go to get my tires replaced due to the inflated cost of labor and parts (tire in this case). I have couple local tire shops that are willing to beat the TireRack pricing (TireRack already offers pretty good deals compared to most other places). I'd say very least you can do is to order your tires from TireRack and have them shipped to a trusted shop nearby.

Thanks I was not aware since I never researched other pairs than 245/265 or 255/275. RS4 are 245/275, wondering if this could affect handling in a way I could feel it ?

After running RE71R street and track, I want a tire that is more civilised.


EDIT: I did some searching and the RS4 seems like a great option, there 245/35r19 has a Thread with of 9.1'' and there 275/35r19 one of 10.3'' wich seems to be a great match for stock wheels !
