21" wheel/tire question...

P1 · 10-10-2016, 09:05 PM

Just bought some Style 375s for the X5 that my wife drives. I realize tire choices are quite slim. Do I go for RFT P Zeros or Michelin PSS tires, which aren't RFT?

How many miles is everyone getting out of their sets? And for those not running RFT, do you just carry a spare with you?

I have a two year old, so would hate to leave my wife stranded somewhere if I put on non-RFTs.

No offense to all RFT believer, but for me, I will go non RFT.
Both RFT and Non RFT are will do fine to drive with puncture. The only difference, with Non RFT, it will deflate. But even before you are running out of air or fully deflated, the TPMS will warn you.
90% of the time with Non RFT, when you got nailed, you can always just drive off to the nearest gas station or tire shop to get it plugged. Just don't pull out the nail or screw, and the tire pressure will hold up pretty good. If no nearest tire shop around, you can just add more air until the next stop.
Even so you are on RFT, by the time it is low on air, you can only drive so far at 55mph and I believe, you can't re-use the tire anymore.
Lastly, both RFT and Non RFT will not do any good on sidewall tear or puncture. In this case, the only option will only be spare tire or tow truck.

Oh, and Non RFT in general will give you better ride.

Thanks Ben. Any idea how long the Michelins will last me?

What are the thread wears between those 2 tires?
The lower the number, the faster it will be worn out.

My Michelin PSS (non RFT) lasted 50'000km.

On Belgian roads, that's impressive...

Alberta · 10-11-2016, 07:51 AM

Ahah yep definitely

I would say that we have the worst roads in Europe.

I currently have 20" wheels with P Zero RFTs and they are very comfortable, but are wearing out like I've never seen before. I cannot keep going like this.

In general, summer / sport tires are wearing out faster.
If you want to last longer, get the all season tires.
I believe the summer / sport tires on the 20" are rated at high 200's or low 300's.
The all season tires in general is rated at 400's, which should last you about a minimum of 35k miles.

I assume this is for a non-X5 M. All the US X5 Ms come with a spare.

RFTs are horrible for the X5 M. The car was not intended to be driven on RFTs. RFTs disrupt the handling characteristics of the car. I would not recommend.

It seems lots of users are getting great wear out of their Michelin PSSs. It's a great tire. Highly recommended.

Alberta · 10-11-2016, 11:41 AM

Agreed on this

Correct. I have a regular X5 35i, but since I bought 21" OEM wheels, felt this was the right forum on which to inquire about the right tires.

The spare you're referring to, is that the standard spare tucked away under the floorboard of the boot/trunk?

Yes. That's the one.

KubaM4 · 10-17-2016, 06:38 PM

21k miles on 21s rft... i liked them ... getting new ones tomorrow

gizmo958 · 10-19-2016, 04:37 AM

im using the Michelin pilot super sports on the x5m , any one have any experience switching to the pirellis . any noticeable differences? i need a new set so worth getting some opinions

trev230 · 10-19-2016, 07:40 AM

Pirelli run flats? I wouldn't do that on an M

How many miles did you get out of the Michelins?

My tires were replaced with Pirelli RFTs when I had an issue with a Michelin PSS. I am now in the process of having them switched back to Michelins after approx. 2000 miles. They are not comparable tires, which is the argument that I made with my SA. Not even close.

The Pirellis are harder and noisier. The main flaw, in my view, is that the tires do not give the level of control found in the Michelin. Stated differently, the Pirellis do not allow the same precision steering as compared to the Michelins. Driving with the Michelins tracked true to the direction of the steering wheel. The Pirellis feel as though you are perpetually hydroplaning. You have a tendency to drift even on dry and smooth pavement. I am informed that this is a characteristic of the RF tire.

I do not recommend. The Michelins are exceptional.

FWIW, my SA told me that the Dunlop RF tires (in 21") are even worse and wear quicker than the Pirellis.

P1 · 11-03-2016, 05:05 PM

Bought the Michelins. Now I need a spare tire solution. What does everyone use?

onfireX5 · 11-03-2016, 06:33 PM

BMW includes a spare with the M. Also an option for the X5.
