Got my 330e in December (just before Christmas) now done 28,000 miles and had first service (delayed service due to coronavirus and dealers not calling me back) my rears are still good with a few more 1000 miles left in them.

Pressures checked on the idrive all ok. I drive a mixture of light and hard dependent on mood. Mostly motorway

She should be due for some rears soon. But gotta wait till it reaches the lease companies minimum.

Mines even more strange as only one of mine wore down in the middle.

I had it checked by the garage in relation to tyre pressure (2.6b) and all were at the same recommended pressure.

Now the other one is getting a little low.

Had the car since Oct and done 13000 miles.

I had a Lexus IS300h F Sport before the BMW and in the 3 years of having it (70,000 miles) only ever had to change the tyres due to punctures.

As many have suggested, lower the pressures on your new tyres and don't rely on those shitty air machines in petrol stations. Get a tyre shop with proper gauges to check them monthly.

I pretty much dismissed this as my pressures are correct with iDrive and the door jam but having looked at this thread again and seeing yet more of the same issue I'm going to ask my local dealer to have BMW look into it when I put the car in sometime toward the end of next week.

Hi

I've got the 330i with the 255 Bridgestone turanza's also got terrible mileage and the only wore out in the middle. I played around a lot with preassure the first and second set of tyres and nothing helped. As a matter of interest, it wore out faster when a ran lower preassure.
After a lot of research the general consensus is that this specific tyre suffers from centrifugal growth. So like a dragster tyre middle of the tyre gets taller as speed hence the middle wearing out quickly. I'd suggest changing brands.

My 330e kicked up a warning of low pressure in the front os tyre - I was then shocked to discover all tyres were significantly under inflated - now I am not too sure - it says reccomend front is 2.6 bar and rear 3.0 - but this seems a lot. I’ve inflated them to that but don’t want to be chewing tyres every 6 months!

Far too high that. I'd say 2.3 / 2.4 Bar max.

My dealer suggested 2.7/2.8 for the 255 Bridgestones
If not likely to get tyre warning pressures if they sit around in the low 2.3/4..

You shouldn't get any warning - just inflate to 2.3Bar and then perform a TPMS reset, which will recalibrate the system to your chosen pressure

[HighlandPete]

Just a little reminder in these pressure discussions, are we all on the same page?

Door plate recommendation, or TPMS 'real time' pressure and recommendations?

[Beemer5to3]

I got off the door plate generally, with a view that adjustment may be needed based on external temperature, and use the monitoring system as a guide. Will always check properly with a pressure gauge though.

I once read that you can run into insurance issues if you don't use the manufacturer recommended (i.e. door plate) pressures. Don't know how much truth there is in that, but knowing the insurance industry I wouldn't be surprised.

I imagine if you had no air in the tyres at all and wrote your car off then the insurance examiner may have something to say.

I know it's not Apple with Apples, however on my G30 (i'm soon to get a 330e)... I have following:-


Front: 245s (2.2 iDrive and Door)

Rear: 275s (2.2 iDrive and Door)


Reason I mention that is rears on 330es are 255s and so 2.6/2.8 just seems very wrong, even with Extra weight of batteies, G30 must be as heavy over rear axle...


I found the Pirelli's were rubbish and wore out quickly, I've had Goodyear F1's for nearly 2 years now and they are as good as new still - 13,000M



Cheers

Always set to the door plate setting, and measure the pressure with a pressure gauge. The main purpose of the TPMS is to detect a significant drop in pressure, the absolute readings are not all that accurate.

My previous 320d F30 touring never did less than 20,000 miles on a set of rear tyres (Goodyear Eagle F1 255/35/R19), so I'm far from happy that I'm getting barely 55% of that on my new G20!

The car came fitted with Bridgestone Turanza's (255/35/R19 (96Y)) - has anyone else noticed such poor tyre life on the 330e or have suggestions for better wearing alternatives (other than the Goodyear Eagle F1), as I need to change them ASAP.......

Thanks for any help.

Mine arrived on the drive 1st September 2020, went in for the HV battery investigation recall on the 15th December 2020 with 1921 miles on the clock, nothing more than local Hybrid mode. The technicians video brought to light that the rears are at 4.8mm 🙈. Car is fitted with 19" Turanza's as yours.

It's a company Lex Autolease vehicle so no worries about when and how much, but even so, that's a shocking amount of wear.

4.8 after nearly 2000 miles

First time with run flats so checked mine today after reading this.
7mm all round after 3300 miles. Pirelli P Zero 19" runflats.
Plate on door for light load 39psi/2.7bar. My screen shows 38psi.

[Blackers]

The non run flats on my 330e have plenty of tread left after 11k miles although some of that mileage was on winters but both sets have over 6mm left

Slightly OT but if you have non-runflats on a 330e what do you do if you get a puncture?

And back to topic, it seems like the Bridgestone T005s are no good on the rear so what's the recommended alternative without decreasing performance much? If we keep to pairs on each axle can we mix front to rear. The T005s seems fine on the front.

You get a repair kit in the boot. Guess a blow-out would require a recovery truck.

Ah I see. So if I got hold of one of those repair kits I could consider non-runflats, which is useful to know.

In my opinion, those repair kits are a complete waste of time. I don’t have a spare in my car at the moment; every puncture (and there have been many) has required a call out to the AA.
My company now insists that new lease cars have a spare. As the 330e I have ordered doesn’t have that option, it got upgraded to 19” wheels and run flats.

I've had no issue with the gel cannister and compressor (only needed it once though).
