Anyone using 265/35 rear and 235/40 front tyres on 19's 326M?

[Wrs]

Not noticed either to be honest.

Mr Wilks helped me with selecting this tyre choice but to be fair I was switching from the 326 to CSL style alloys (which were 9.5j). I just (wrongly?) assumed the tyres would be ok to go back on the 326 alloys when I reverted back.

If you post up some pics that would help a lot , the numbers on tyres / rims & offsets only really factor when you edge towards the limit either way , 265 35 on a 9.5j is heading towards the boundary (imo) but still workable if the car isn't super low , 265 35 19 on 9j is pretty much the boundary for a sports car although it would most likely beyour front arches that gave sign of rubbing with a 235 35 19 8j ?

No worries - will do over the weekend. I can't say that I have noticed any rubbing.

It all makes sense now with your tyres recommendations here http://www.z4-forum.com/forum/viewtopic.php?f=49&t=91142 being based on 8.5j & 9.5j alloys vs the 326's. I didn't give the tyres a second thought when I had them switched over to the 326's . Only covered 1-2k miles since though.

Thanks a lot. The arches look like they can take a full boot and two passengers.
For now I think I'll go with 265 tyre width but will try to get more info on the possible 35/40 or 30/35 aspect ratios. If I get 35/35 looks like there will be 10mm difference in rolling radius between front and back and I still need to learn what that means :headbang:

I am running 245 / 19 Contis front and 275mm / 19" Contis in the rear. Ride quality is dramatically better and handling on Mulholland Drive with the bigger rubber is significantly improved. Plus, the fat tires make the car look that much more aggressive.

How is it on other roads? :lol:

I mention Mulholland because it is rather famous twisty road. It's good on other roads as well :rofl:

Which profile did you go for - 30 rear 35 front or the 35 rear and 40 front.

35 front and rear.

Any photos from any of the sides?

I now need new tyres very soon as I am on 4mm and was just about to purchase the 265/35R19 and 235/40R19 today but still not sure about rubbing. Car clearance will be around 15mm higher and the arch gap will be 15mm shorter so on paper it should work.

With the size you've got I'll have around 3mm more clearance and 3mm less arch gap compared to my current setup 255/30 rear and 225/35 front.

Did you find out what the difference means?

OEM sizes of 225/35/19 and 255/30/19 give a 14mm difference in circumference front to back, I'm about to hit the button on 235/35/19 fronts and 255/35/19 rears on OEM 326m's as per recommendations on here but that gives a difference of 44mm in circumference front to back! :?

Bear in mind 326s are 8j front & 9j rear.
Ideally 225 35 19 works well on the fronts . I tried 225 40 19 on previous e89 & had very minor rubbing when pressing on
265 on rear 9j ? 245 or 255 is ideal width so if you must go 265 then go 30 profile .
I had 255 35 on my 326s & for me it's the best all round fitment for comfort + wheel protection.

I had thought the consensus was to step up to 235/35/19 Front and 255/35 Rear on the 326's when moving away from the RFT's? Now I'm just worried that
A) I've got the sizes wrong? and
B) The big difference in overall circumference front to back, or doesn't this matter? :?

Size is fine, the only difference is your front wheel. Which is 10mm wider than what Mr Wilks posted. Probably cost slightly more, but performance wise should be the same, or at least very very similar.

Ive no doubt the 235 35 will work fine & without issues but generally speaking that size would be for 8.5j 19s & not 8j .
