Hoosiers and anything else without an E-marking are illegal in the EU (RA-1, NT01, RS-3 etc). And R888s and other semi's will soon be illegal too..good thing that they are currently too occupied with other issues to push through the legislation.
You must be a rich man for want to run the 225 an
d 235 R888s on the street at 1000$+ a set and rapid wear.

15x10 6UL, 245/580R15 Hoosier R80, Autokonexion +30mm fender. I also cut the lip off the fender (what you would normally roll on a steel fender) to make sure I still had 90* of wheel input at full bump.
It fits

Where did you get this info about other semi's becomeing illegal? I hope that's just a rumour, as that would eliminate avery wide tyre choice we have here for Miata's.

You're right I forgot about the E-marking thing. A few years ago it was alittle bit different in Holland, as you didn't need an E-marking on your tyres.

I personally lack 225/45-15 in anything else than R888 (RS2 is not an option).
Kumho V70A have worked nicely for me in 205s (1% faster than R888 and don't overheat as badly), but it has been a long time since they produced 225/45. Order 100sets and they will make a batch (so I've been told by Kumho Motorsports)...
I don't like the feeling of 225/50, feels like off road tires.

It will fit with flares (I had Jubiride in mind), even at a lower offset than these 6UL's.
I do not intend to slam the car so I don't believe hitting the wheel well will become an issue.
But I'm just thinking aloud here, I'm not really intending on making this happen anytime soon, but you never know.
Sometimes you just got something in your head and you have to do it, just to get some sleep at night :P.

The issue is the height. Because that's a 24.25" tall tire, you will need to run a taller bumpstop in order to keep the tire clear of the top of the fenderwell and shock tower. Because the bumpstop is taller, you lose bump travel if you maintain ride height, or you lose droop travel if you raise the car to compensate. The only way to maintain travel would be to run a custom shock that's sized to maximize travel at a 4.7-4.9" pinch weld height, and if you have that kind of coin, you should just be running R80 Hoosiers instead.
You will also rub the front bumper and the back of the fender when turning, both due to the height of the tire.
This is why you have to stick with a tire no taller than 23.0", regardless of how wide it is. The three popular Miata tire sizes are 205/50 (23.0"), 225/45 (22.9"), and 245/580 (22.9").

There you go opgedronken
245
22.7"
Just a measly 1050$ before shipping, so not much more then the toyo 225 equivalents. And its a streetable tire too (kind off).

Just noticed this. I promise you that the 235/50s will not fit, even if you flare the car. If you want 235/50s, and you expect to drive the car hard, you will need to tub the car front and rear and run a very low offset wheel. Flares only help with fender clearance - if you are driving a tall tire up into the top of the fenderwell, flares won't help.

I’m completely eliminating the stock fender wells just to run a 23.5" OD tire. 23.5X11 R16 to be exact.
23" OD is max you can run and have a proper working suspension in combination with the stock wheel wells regardless of what flares or fender lip mods you do.

I do not intend to track the car at all, there really are no feasable options in holland.
This setup would be purely street driven, and not intended to be the most "functional'.
I'm wondering then how do people drive on their 225/50/15, or a very commonly used size 215/40/17?
These are both about one centimeter less tall then 235/50/15.
The front fitment wouldn't trouble me that much as I wouldn't even think about using 235 there, more likely a 225/45/15.
As for the 245/40/15 Avon's they're actually pretty affordable down here, it's just that I'm shooting for a particular look

.i don't know about 215/40R17, thats probably an NC fitment if anything.

It's very commonly used on 17" tuner style wheels, atleast here in Holland it is.
I've dug up a quick pic of a reletively fat tyre in that size, and I have to say it looks pretty doable.
Edit-- 205/45/17 is slightly higher than 235/50/15 even!

Stock size on the MSM is 205/40/17, 215/40/17 can be run without rubbing at stock height. I ran 615Ks in 215/40/17 before upgrading to a 6UL/RS3 combo. Never had any rubbing at stock height on street or the one track day it saw. Once the car was lowered rubbing was easily induced with dips in the road or mid turn bumps at silly speeds.
No rubbing on autox courses with 225/50/15 V710s on 6ULs.
