How many miles did your tyres last?

[ksher]

My Zed has done nearly 11,000 miles since June 2010. I checked the tyres today, and the tread depth is 5mm (front) and 4mm (rear). It is like a pair of Bridgestone RFT is needed very soon for the rear.

How many miles did your rear tyres last? The rear RFT on my previous E60 523i Sport lasted about 20k miles.

Hmmm, my mileage is a good bit lower than yours, although mine is just over 2 years old, but I've never checked the tyres. Is it recommended to let the tyres run right down to the legal limit... (1.6mm) ? How many miles are you covering for your daily commute, or is the wear just down to pleasure driving?

 

[ksher]

From home to office is 24 miles, i.e. 48 miles a day. Pleasure driving, all the times .

But I really think my two Z4 (E85 ane E89) have faster tyre wear, than other BMW I had before. Probably they make me drive more enthusiastically.

I am going to change them when the depth is 2mm.

23k on rears but had a puncture or would have got a little more, 28k on fronts

How did you manage that?

I swapped mine over at 22,000 miles and the rears had 3mm left and the fronts 5mm, I' would have probably got 30,000 from the rears. Have now done 35,000 miles and there is still quite a bit of tread remaining, probably another 10,000, think the Bridgestones are a wee bit hard

Want to change all four for some continentals, if I said that the Bridgestones were poor, that would probably be the biggest understatement of the century

sars, you mean you swapped the fronts for the backs? I think you can only do that with the 17's where the fronts are the same as the backs... in terms of size :?

Will you go for Continental runflats, or "proper" tyres?

Of course i drive within the speed limit, apart from the time i ended up on the speed awareness course.

Just drive fast and smooth, no burnouts and hey, i'm in a 35i - what do i have to prove on the road

Apart from the odd head to head with my mates boxster i'm not one for flooring it, don't do track days and around these country lanes it's not cool to drive like a lunatic. I don't ever want to come round a bend and end up taking out riders on horses, people on bikes or other drivers so giving it some welly has to wait for the autobahn

I think I should set my car in "Normal" mode all the times.

Yes I have the standard 17" wheels so they are the same, as I do 25,000 miles a year having 18" wheels, even if they do look pretty, add a lot of unnecessary cost. Current price for a continental rft for mine is £142 fitted, or £250 for the 18" rears

Will definitely keep the run flats, just not sure which brand to get, obviously excluding Bridgestone

I put mine in sport more and more, find i am getting better fuel consumption

 

[iwatchlive]

I'm on 19" all round, have over 19K on the clock and the fronts have ages on them. Replaced the rears at 16K. £260 a tyre.

roofless, 23K on the rears...phew I just love that. :wink: ...just wish I could do that myself :wink:

BMW say non run flats will invalidate the warranty on any steering and suspension issues......

I shall continue to fit rft, just not those manufactured by Bridgestone

even though i tend to be

:lol:

i do eventually get through tyres and when i will need to change them again this issue of warranty etc raises one question, does anyone have any experience of runflats other than the bridgestones and what would you recommend? other than non run flats

Starting to think about this myself, have probably another 6 months wear left in them, choice seems to be between

1. Continental Sport Contact 2 SSR (RFT)
2. Pirelli PZero (RFT)
3. Yokohama Advan Sport V103S (RFT)
4. Michelin Pilot Primacy HP (RFT)
5. Michelin Pilot Sport 2 (RFT)
6. Bridgestone RE050A (RFT)

These are for 17" & 18" wheels, any comments or advice?

That's interesting as I asked my dealer flat out about fitting non run flats, and they said there were no warranty issues, it was all about the safety and the fact the cars were designed to run them. They said I can fit them if I chose to without comeback. I pressed them on the warranty angle and they confirmed (both reps I was talking with) that warranty would be unaffected.

So, is there less chance of 19" rims cracking if we go for non-RFT tyres?

I don't think there's enough evidence to say one way or another. I'm using my own intelligence (!?) to think about how impact waves travel, and I would have thought, as the wheels seem to crack where the tyres meet the inner rim, that by absorbing impact energy in the tyre this can only lead to less energy reaching the wheel. Happy to be proven wrong, but most believe that the hard sidewalls on RFT's pass along the impact energy and make the wheel flex more, which results in failure ultimately.
