Because 20" and 21" are not ideal for performance

Perfect

Thank you RingMeister, I had been in Rovinj a couple of week ago, beautiful place.

It is! Great driving roads as well!

Did you have any rubbing? I am considering installing the same wheels in a F80 but with 265/30 and 285/30. Do you think 10mm spacer would be enough in the front? I will be receiving my car in a couple month and not a big fan of the 666 wheel from the Comp Pack and want to keep OEM so considering to go for the 343m wheel which I also think it is beautiful and reminds me the 437s as well. Thanks.

Seems like owners of stock 18 and 19 wheels can safely increase the rolling radius/sidewall height on stock suspension without rubbing.

I haven't played with all different configurations to find matching tires in different sizes yet,but I'm guessing for example I could do a 265/45/18 and 285/45/18 (an increase of 3/4" sidewall height over stock) and not rub unless perhaps fully loaded down.

Similarly, I wonder if the 19" crew could run 275/40/19 and 295/40/19 on stock suspension and wheels.

I know lots of people prefer shorter sidewalls (and gearing effects) as they upsize, but I think there's a lot to be said about carrying speed on this chassis, on real roads, and the benefits of more sidewall.

I have done several trials and errors with a lot of different tire sizes and at the end my combo seems to be the IMO the perfect one. You can have 265/30 with 295/30's with 10 mm spacers in front and rear directs. Congrats on your new toy and enjoy.

In stock suspension sounds very plausible.

Thanks Palomequet, appreciate the help and glad to hear I may be use to the tires that comes with the 666 wheels. The hard part is the waiting for the car to arrive... By the way, did you had any rubbing when the car is full? My is an M3 so I will eventually have 4 people inside and was curious to know if a full load I could have some rubbing.

I have been wondering this myself.

Anyone have an opinion on bumping up to a
20x11 et 37 on 295/35 for the rear? I know a 305/30 will fit so I assume this would fit as well. I know it will raise the car 3/4" but also delete that much wheel gap as well.

Here I was thinking I had to buy a set of 19s to get a 35 series tyre up front

You sure these down rub the inner fender liner - I've seen scuffs on my inner fender with ps4s 265/30/20 on 666

[sknobs]

255/35/20, 305/30/20.

Love it.
Next step is a small .8-1" drop in the front and I should be happy.

[Palomequet]

Congrats!!!!

[HotRodM4]

So, you guys are telling me I can put 255/35/20 PS4S tires up front on my 666m comp wheels without issues? 🤔

[Palomequet]

Absolutely

[Palomequet]

Perfectly

I did a lot of trial and error in another of my treads and I’m sure that you’re going to like the results. You can follow me in instagram at mflightmexico if you wish, to see the evolution into the F8X platform that I developed

I think there might be something off in the chart....

If the sidewall height for tire one is 3.5 inches and the tire height for tire two is 3.5 inches..... how come it's .84 percent different?


Or is it just a rounding thing?

Being less than 1%, I’m assuming the 3.5 number is a longer decimal with more numbers after the 5

I think 255/35r20 will rub when turning. That's a HUGE diameter tire. I am on 275/30r19 and I rub on the fender liner on full lock on 19x9et23.
