Tires

[SHADOW4]

Getting tired of the RTF's. ( they get more noisy by the mile )

Looking at Falken 452/453 or Michelin PS3.

Have:18x8 and 18x8,5 294 OEM rims.
225 front and 255

Any point in going up to 235/265? (on the 294 rims) I have 18mm spacers on the rears (for looks)

What happens with the TPM? As it really doesn't messaure pressure but tirespeed it should still work?

All kind of tips, experiences appreciated.

Thanks

Changed to a set of Falkens about 500 miles ago and love them. They are quieter; the car handles better in the dry and in the wet and the ride is much more comfortable. They were also a lot cheaper than a set of RFT. I'm off to the continent in a few weeks and one of my main concerns was that if I got a puncture then I would get stranded because most places do not keep RFT in stock. I should also say that I also bought a small compressor and a bottle of repair liquid just in case I get a puncture.

TPM stay the same with any tire. TPM measures tire pressure, FTM measures wheel rotation speed.

Do they have the hankook ventus v12 evo in Sweden?

Car and Driver gave them a great review as a budget tire. Dry grip exceeded that of the benchmark/baseline micheline PS2s.

I have them in 19s on the 35is and they're a great tire for the price.

Hi jparnes1, And the E89 does not have A true TPM wich not messaure pressure in individual tires but senses different rotationspeed on a punctured wheel from the others. I HOPE I am wrong but this it how it has been explained to me somewhere here around the forum. Usually I don't care how it works as long as it works.
But now feel I have to study this system.

Thanks, I will check them out.....

I went up to 235/265.

Love it.

Does it look beefier? Meatier? or what the english word are?
That's why you love it? It's what I am looking for :-)

No problem with the tires looking like they want to " popout" ?

What brand?

Thanks

I bought the Michelins and they've been great. A bit more forgiving than most RFTs.

I've had ps2's and the hankook evo v12, for the money the hankook cannot be beat. Great tire.

I've had the PS3's and changed them to Hankook. What a difference.

Won't the green slime hose up the TPM sensor if you have to use it?

E89's dont have sensors in the air valves.
They use the ABS system to measure the rotational speed of each wheel.
If a wheel shows a slow and continued trend of a different rotational speed to the others and its own past history then the computer will signal it as a potential slow leak / flat tyre.

I haven't heard anyone confirm what happens with a blow out on the E89.
HankHenry said the dash indicator came on with a blow out on his 335i - perhaps they use a similar system to the E89.

Doc, when I go to Vehicle Info / Vehicle Status, it says TPM (tire pressure monitor). What you're describing is FTM (flat tire monitor) which measures rotational speed. A quick way to see what you have is to look at the valve stems. Rubber ones (like on my 2006 E60) are FTM, metal ones (like on my Z4) are TPM.

Ahh, there's our problem...

The US manual has two options - see attached images. TPM and FTM.

The Manual in Australia (and I imagine in other places) has only one, and it is a standard feature, not an option. Its called RPA for Runflat Monitor, and the descirption is the same as the FTM.

The dash display in the iDrive calls it the FTM.

Perhaps this is a common standard outside of the US, which would explain a lot of the argument over this topic over the last couple of years...

Hey Dr Stig, are you still running RFT's or have you changed yours?

don't worry, i just saw your post in another thread re that your onto non-RTF's.

Yep. changed. I wrote the wrong name of the tyre in the other thread...

They are the Dunlop Eagle F1 Assymetric 2.

Love them.

U.S. models do have TPM valve sensors.

So either system should work with any type of tires.

Doc, thanks for clearing this out.

I switched all four to non-RFT tires at around 25K (which is when my fronts were getting bald, and having already changed the rears at 14.5K). I went to Bridgestone Pole Position S-04s. I have to say this was one of the best things I've done to the car. Runs much smoother now and the performance is terrific. Plus the cost is a LOT less than if I went with four run-flats.

I just ordered a set of these and will see how good/bad they are compare to the RFT RE050...
