Considering 255/35/19 & 235/35/19 on 10J & 9J

This is what I mean about ‘over-tyred’.....

What are the offset dims?

It’s not an issue with ET, it’s the fact that tires are standard M4 sizes. The fact that they physically fit, doesn’t make them right... I’ve decided I’m definitely going to change them.

Re un-sprung weight, these are genuine M4 forged alloys, so lighter in a 19 than most 18’s and certainly the E89’s standard 19’ factory offerings

[Ed.Straker]

I was just intrigued how they sat in the wheel well..without the ET it’s impossible to work that out..I’ve looked it up now.

I see from that lookup that indeed the M4 alloys are around 3-4kg than the normal 19” crackers..

You must be the first forum member to be down sizing your tyres

I popped out and took a few pictures for comparison. Not sure if it’s the width/offset of the wheels as I’m on a 265 so only 10mm down in tyre size but an inch thinner wheel from you.

So that looks a bit more sensible, that’s comparing 265/30/19 to 275/35/19... the profile makes quite a difference to the bulkiness of the tyre.

The wheel and tyre, on my car sits under the arch (not by a lot) but it does, so the 10J ET 40 in itself isn’t a problem. I realise some are happily running 275/35/19 and maybe the extra grunt of a 35i or 35is justifies this

[True-Blue]

This is a 255/35/19 tyre on a 10J rim... looks ok, but appreciate some tire brands are better than others in terms of rim protectors, and some are naturally wider/bulkier etc...

The genuine M2/3/4 437m wheels are the exact same offset as the Z4 E89 wheels e.g. 326M. That's one reason I went for them too, along with strength and lightness from being forged. The forging process is impressive to watch!

My reading on the subject suggested not messing around with offsets. Scrub radius:

This is also a useful site for comparing tire sizes

Mainly because I think it looks a bit like a moon buggy!

and, I think having circa 250 BHP-ish it’s a bit ‘over-tyred’ - 255F / 275R - bigger isn’t always better, although I can understand why a 35i or 35is owner might want to go that big

I’m always interested on how the handling is affected by those sizes that are clearly a long way from the OE settings..

Without doing an A B swap you’ll never know..

Of course most oversized tyres/wheels are done for cosmetic reasons...

Again not sure how stretching a tyre over the widest rim works, but it won’t improve rim protection....

My e89 definitely feels more agile & lighter on its feet with 17” wheels/225 tyres, it doesn’t stop me from fitting the 19”s in the summer months though purely because they look so much better. It feels a little “clumsy” with the bigger wheels fitted

Rob, apologies if I’ve missed this, but what size tires do you have fitted to the Veemann’s?

Thanks again,

Yes so I can see that with a 30 profile, 265/275 works well... but, in theory, going down to 255/35/19 should also work but give a more compliant ride

255/35/19 & 235/35/19, m-sport suspension with no rubbing.

Great, thanks.

I’m guessing the Veemann’s are 9.5J rear.

I’ve found a couple of posts from @mr wilks also advocating 255/35/19 on 9.5J and as a 10j rim is ‘only’ 12.7mm wider, I’m still thinking 255/35/19 is the way to

[Smartbear]

Yes, 8.5f & 9.5r. I purchased the wheels/tyres from Mr Wilks, he knows what he’s talking about

After much research For my 35is - stock in every way - I am getting a set of M437 genuine alloys and putting 265/30/19 on the rear and 235/30/R19 on the front. Seems 275/255 is a tad too much.

Does that sound OK guys please?

This is the size of tyres and width of rims on our car. You can see from the pics how it looks.
