What is the problem with running 275's on the back???

XPorker
I run the PS2 and think they are great and have cups for the track.
265X30X19 AND 235X35X19 Extra Load Thats the correct size.

I know 1 that runs 275x30x19 and 245x35x19 on his CSL ok

Gaz has conts on his CSL and they are not as good as my PS2s
He is geting PS2s when the conts are done.

Apart from the fact that technically the 275 section tyre is not the tyre that was specified originally for the car, there's nothing "wrong" with using the wider section.

As the originally specified tyre for ther rear is a 265 section it just seems sensible to retain the recommended sizes both front and rear (especially for road use)

As regards the PS2's, I've run them on my E46 330D Sport for the last 18 months and liked them.
Antony at Simpson M/sport was most vociferous that they'd caused major handling problems on a car they'd had in.

The car in question had been fitted with a new set of PS2's and the owner had complained the car handled poorly, after several checks of the geometry they ended up bolting another set of wheels on (fitted with Cup tyres) Bingo, problem solved.

They put the problem down to the PS2's having soft sidewalls (which they are softer than the original Pilot Sports hence the PS2 rides better and is quieter)

I decided that it was better to be safe than sorry and thus put another litre in. After this the display STILL showed +1.1 litres.

It sounds like you overfilled your engine by about 2 litres.

0.9l is a normal level. Unless your engine is seriously ill, you would have to drive at least 1000 miles around a track in order to burn off that much oil.

If I was you, I would take your car into a dealer and to get them to check the level manually. This will involve removing the airbox.

I shall do a video later how to remove the airbox

Here is a good link on how to remove the airbox

Back on the tyre bit !!!

Im moving from the std 265 / 235 set up to 275/245 as recommended by thorney , as he has done extensive testing on both, and reckons the 275/245 handles far better on road and track because of the wider track, also going for some proper race wheels , to keep as a second set , that way I can keep the cups on a set.
Rays RE30's which are lighter than the standard CSL's and have a wider track also, so no need for spacers etc.

Will post up some pics Wed night as im getting then put on during the day..

I have Conti's on my CSL - they were already on and almost brand new when i bought it - but have to say so far they feel perfectly fine on the road - i guess the track day at Brands will give me a better impression.
I did a check on the oil this morning before, during and after a decent length run - exactly how it is described in the CSL manual. The "long term" check read +0.8 which im assuming is perfectly fine. However, when i stopped, turned engine off, waited a good 3 minutes or so, turned ignition to position 1 and held sport button in - it read +1.1 - i know it says that this doesnt give the most accurate readingbut does this seem right??

Had a chat witha BMW technician this morning about checking the oil level with the dipstick. He commented that the airbox screws can become seized and thus be a real PITA to remove.
They used to remove the undertray and check the dipstick from underneath rather than do battle with the screws in the CF airbox . . . .

I agree - sounds horribly overfilled - and I'm not sure even 1000 miles around a track would burn that much off

I predict a massive oil eruption sometime soon

Xporker,

Have you had the oil level checked?
