CSL Tyres
Hi everyone
I need to fit some replacement tyres on my CSL's. They are fitted to a Z4MR.
It seems to be suggested 235/35 front and 265/30 rears are the advised sizes? That's what is currently fitted too.
I can get them fitted at work and so far I have been offered....

What are everyone's thoughts on sizes, tyres and where to get them from?

There’s two sizes
225x40x19 (F) 255x35x19 (R)
or as u mentioned
235x35x19 (F) 265x30x19 (R)
Suggest you look for a fitted price, as I found for example Costco would do the 235 front fitted in MPS4s’ for £310ish (if ur a member) recently.
Then there’s the debate about tyre pressures, as I would suggest running a wider tyre you may need to compute a lower PSI as the weight is distributed over a larger surface area
18” recommended pressures
225=30.458 (30.5)
255=31.908. (32)
Therefore (225/235) x 30.345 = 29.161
235=29.161
(255/265) x 31.908=30.7
265=30.7
If you read a number of posts, quite a few said they had better M handling on a lower pressure which kinda supports this computation

Thanks both.
I'm swaying towards Michelin - prices fluctuate massively everywhere i call as usual!

Blackcircles are offering a 10% discount at the moment I believe.

I just came across that actually. £616 delivered for PS4's seems pretty decent!

The wider the tyre, the more vertical weight distributed over a larger surface area, where on cars I’ve owned in the past which have had different tyre sizes on the plate they’ve had different pressures.srhutch wrote: ↑Wed Feb 27, 2019 9:51 pmWhat’s the logic in you calcs there Jem?Jembo wrote: ↑Wed Feb 27, 2019 12:59 pm There’s two sizes

Confusingly some have had higher, some lower pressures with wider tyres.
This, coupled with some googled posts where people have found M Zed’s less ‘skippy’ on slightly lower pressures, suggested the pro rata formulae for debate...
