The rears will be 5cm more “outboard” than standard, i.e. about 3cm beyond the bodywork. Ok if you want the Carlos Fandango look 🤔
 
Front Axle:

Standard: 18x8J ET47
New: 18x8.5J ET20

Tyre: 225x40xR18

The 225mm tyre is the minimum width you can use on an 8.5J wide wheel.

In terms of size, the wheel will poke out 33.4mm more than before. This is far too much and will stick out of the arches and almost definitely rub when turning the wheel.



Rear Axle:

Standard: 18x8.5J ET50
New: 18x10J ET20

Tyre: 255x35xR18

The 255mm tyre is the minimum width you can use on an 10J wide wheel.

In terms of size, the wheel will poke out 49.1mm more than before. This is far too much and will stick out of the arches.



Now to be helpful :D

I am also looking for some ARC-8s soon (switching from MV2) and the best sizes in my opinion are as follows:

Front Axle:
18x8.5J ET42

Rear Axle:
18x9J ET45

These sizes give a front and rear poke of 11.4mm more than before. This is good for me as I am running 12mm spacers front and rear so it will match those. Plus with this setup you have the option of fitting more spacer. Its quite difficult to fit negative spacers :P
 
Thanks All super helpful it makes sense now!

So in short none of the strom str2s will fit our cars?

None. ET is too aggressive. If you want CSL replicas (styling 127/163 plus 359) consider:
avus racing
vmr vb3 (v703)
riva dtm
atomic csl
Avant Garde M359
sportline 8s
apex arc-8
wsp italy
atomic csl
VEEMANN VC359
CB MODEL:BM10

This is a really useful list, thanks Panta Rhei!

Cheers mate so looking like Veemann or Riva will be the right price bracket and look. do you have any feedback on either of the reference fitment and quality. I do like the concaved look but still needs to be usable as will be tracked from time to time. I am running BC Coilovers and will run 18” wheels

Cheers
 
G'day mate,

You will most likely need to visit manufacturer homepage and find desired wheel and then check if they fit.
Fronts:
8J ET 35-50
8,5 ET 40-45
Rears:
8,5 ET 30-50
9 ET 35-45
OFC this measurements are approx and Michelin 225 can be Goodyear 235 :|
Fronts in Z4 are pain in the arse, because of wheel arch shape behind side marker.
 
Hi All,

Following on from this I have narrowed the wheels I’d like down to the below:

Riva DTM 18” which are
Front 8” ET 34
Rear 8.5” ET 37
£570

Or

Veemann VC359 18”
Front 8.5” ET35
Rear 9.5” ET45
£799

I want a nice looking good quality wheel. I am lowered although not crazy on BC adjustables and and would like to be able to use car for some track use so looking for best looking without rubbing.

Any advice for which of the above would be best please?

Many thanks
 
Just acquired my first e86 with 108 style 18” wheels with Bridgestone Potenza RE050A run flats. They still have around 7-8mm tread on all the tyres but I have never been a fan of run flats and want a better ride quality. I was thinking of changing them once they are due for replacement but based on my light use that could be a while.

Is there a recommended non run flat tyre for these 108 style wheels. I see many recommend the Michelin PS4, but do other tyres match this wheel better.

Any thoughts?
 
There is no connection between alloy and tyre brand in the terms of fitment.
PS4S - great tyres. 2 years on my previous 3.0si and I cannot say anything bad about them.
 
Thanks Panta Rhei - probably will go for the Michelin PS4 or 5 - Michelin’s have served me well in the past.
 
This is a great thread - loads of useful info. I'm another newbie, having just a week ago picked up my 58 plate z4 E86 Coupe. Before I bought the car I noticed that the MOT in May 2022 had advisories for all 4 tyres, perished and cracked sidewalls. I made a point of this to the dealer and eventually got them to knock some money off (£500) so I could put on new tyres all round. I've really no idea how the tyres got through the MOT at all and upon closer inspection I discovered they were the original Bridgestone runflats. I checked the DOT markings which gave the manufacture date as 4307. Wondering if I hold the "not to be proud" record for having the oldest tyres on a z4 Coupe. So now I've got the car that's top of my to do list, to replace the tyres. The runflats really do spoil the driving experience and as many others have said it is like driving on tram lines.
The car is really being used as a weekend driver, not a track day car, but likely to enjoy some spirited driving. Any callouts for tyres, appreciate it's really down to personal choice. I guess the obvious answer is don't get run flats :lol: Was thinking of Goodyear Eagle F1 Asym 5/6 or Continental Sport/premium contacts. Nothing can be worse than what's currently on the car Anything else worth considering?

Cheers.......

So I got my tyres replaced at the weekend on my recently purchased z4 E86. Went for the Goodyear Eagle F1 Asym 6 in the end. WOW what a difference to drive on from the original Bridgestone Runflats - vastly improved driving experience!

Will 108 tyres fit on 224's?

yes.

Although 108s would have had 225/40 x 18 fronts and 255/35 x 18 rears, but 224s on an M would have had 225/45 fronts and 255/40 rears.

I'll go check the tyres just in case. I bought them 2 years ago and sized them up a profile for comfort, they have been sitting in the garage because of COVID. My local tyre guy ended up going bust he was a one man band. They are supposed to be getting fitted next week but originally were going to go on 108's but I managed to get a hold of 224's so need to go on them now as the 224's are bald.

okay just to complicate things

I have 215/45 R18 (fronts) and 245 40 R18 (rears)

Will these fit on 224's? or will I need to put them on the 108's?

It's a 3.0 with M sport suspension.
