Wear of tyres and replacement?
 

Hello

Have any of you of to replace their tyres of their X5 E70?

How much of kilometers or miles did you cross with the tyres of origin?

In Europe, many persons say that tyres in 20" make no more than 25.000 kilometers (= 15.500 miles).

Thanks a lot.

I have the 20s with around 10,000 miles. I reckon the rears will do another 10,000 but not too sure about the fronts. Wear is pretty even across the tread though.

Yep, 15-20K on the 20" is about what you will get. If you use the "sport" mode often you may get a little more. They seem to wear more on the outside edge so the "sport" mode prevents body roll over on the edge.

I just replaced my 20's with 13k miles - they started to make a terrible road noise. When we pulled them off, the inside on the rears cupped badly causing the noise. THe rear seams to squat and cause this. BMW advises that this is normal, i dont agree. We did the alignment and everthing was in spec. Its a shame because i had plenty of thread on the rears. I put on 19's with all seasons.

Any one have this problem??? - I will take pics and post.

Wow - only 20K....I'm surprised they must be super soft or something. Whats the point of the warranty if they only last about a year....

We can say thus well that the tyres of X5 E70 know an abnormal wear what does not keep silent about the case with X5 E53.

Would the Run On Flat technology be an explanation this too fast wear?

With my X5 E53, I had made 45 000 kms (28.000 miles) without changing tires (19 " Michelin Diamaris).

With my X5 E70 I am thus going to have to change tires twice as often????

No more opinion on this subject? :confused:

a bit of topic but what sort of money are you expecting to pay for new tyres on your 20" any idea ?

Here are the prices for a change of tires 20" in France:

- 2 front tires 275/40/20 DUNLOP RUN FLAT with installation: 930 € (1.370 USD / 690 GBP)
- 2 rear tires 315/35/20 DUNLOP RUN FLAT with installation: 1 018 € (1.498 USD / 755 GBP)

Almost 3G's for four tires :yikes: :yikes:

YES!:thumbdown :(

Yes ! :banghead:

Can we replace the tires Run Flat of origin by classic tires not Run Flat?

Yes...but, you will need to "cover yourself" in some manner if
you get a flat.

In France, a lot of people says that BMW forbids to replace tires run flat by tires not run flat.

What is it somewhere else?

According to me, if the dimensions (275 / 40R20, 315 / 35R20), the indications of loads (front: 106, rear: 110) and of speed ( W ) are respects, there is not an incompatibility.

It is just necessary to buy a spare wheel or a kit of reparation.

No?

I have no idea what BMW NA's position is for the US...whatever the
official line here, it is probably based on marketing inputs, (read: buy
replacement tires from the stlr), and/or the lawyers writing the disclaimers
for the company.

Yes: one will need a spare wheel/tire or a plug & go kit and small compressor.
At the least, a couple cans of Tire Goop, which sometimes don't work and
provide a mess for the tire changer to deal with.

I run non-run flats on our Vette and have a small plug & patch system
and a mini compressor; I don't want to have to use them, however.
I have done a plug & patch on a motorcycle tire during a trip and it
got us to the next city for tire replacement, but working on a small
width m'cycle tire, easily accessible, is not quite like hammering on
an X5.

The problem with these newer cars going to runflat tires is that initially,
most tire stores and even many dealers will not have that size(s) in
stock. Couple that with some adroitness needed to change out a run
flat tire and it's not necessarily a magic carpet situ.
My 25Cts is up...

My rears are gone at 11,000 miles. The inside of th erears are to cords. Clearly there is alot of Negative Camber (factory effort to eliminate oversteer in favor of understeer), but also the toe in must be excessive to have created teh cupping and feathering of the tread blocks. I feel foolish to writing this but I never even thought to check the rears this soon. My wifes drives this X5. I track M3s AND 911s so I know a few things about alignment.

I am pissed that these really expensive 20 inch run flats are gone so quickly. Yes yes I know low profile tires go quickly. I am going to do a custom alignment to see if I can get the scrubbing reduced before I spend a chunk of change on new rubber. The fronts have had pretty even wear.

Does any one know the factory Alignment specs for the 4.8 X5 Spport package with 20" wheels???

Any comments from anyone who has chosen to differ from factory specs?

Any comment on a tire choice? I do not like the Run Flats and will not buy them. They follow every imperfection in the road like Track/race tires. Is there a High Perf. tire whick is decent in rain and occasional snow?

Thanks for your help!

would it be safe to assume that regular wear and tear is covered if you have the tire warranty package?

Non-runflat 20s that are all-season.. your only choices are the Michelin Latitude Tour HP or the Toyo Proxes S/T. Michelin to play it safe but the Toyos have a very sweet looking tread. I went with the latter.

How do the Toyos compare to the run flats? noise, ride, handling, tram-lining, feel? price difference?

Dunlops, 21" on 215 rims, 275 front, 325 rear. Just hit 20,000 this morning.
Mine are going well, I really look after them - so no dirt roads etc. Will easily reach 30,000kms.

Cheers,

Noise is the same as my run flats which was very minimal in my opinion on local and highways. People suggest they get louder as it wears but I personally don't expect to put that many miles on them anytime soon. And again, runflats weren't even that loud for me.

Ride & feel is much better - the bumps in the road are no longer "thumps" in the road. It actually feels like I'm on rubbers now. Biggest difference here.

Handling is slightly better, more stable, but not a huge difference even though they are noticeably wider. No experience in rain or snow yet as it's only been a week.

Tram-lining I have no experience with as I drive only local paved roads.

Price difference - the Toyos are definitely cheaper - like $200 ea. compared to $350+ for runflats, on top of the fact that you need an entire new runflat should something go wrong with it. No $10 patch jobs here. The Toyos are also slightly cheaper than the Michelin non-runflats. I would've been very satisfied with the Michelins non-runflats (which I got as OEM runflats) - they felt very good and handled well even in snow, but I felt I owed something less boring a try. One look at the Toyos and I was hooked. Good ratings there too.

Hi

Does anyone know of non-runflat tyres for the OEM 21’’ rims (275 Front & 325 Rear)?
I still have yet to find any non-runflat tyres for the Spider Spoke 128 rims.

Kind Regards

One quarter inch tread depth with even ware on both front and back.

Are the Toyos a slightly wider tyre over that of the Diamaris at the same size of 285/45R19 does anyone know?

My understanding is that most run flats have short tread life and wear-out around 20,000 to 30,000 miles. Yes or no?

Do the larger 20's wear out sooner? Or is that the 20's are dry weather high performance tires that haver softer treads and normally wear out sooner?

I must say that I am not a fan of run flats, I find that blow out on my normal tires are very rare (has never happened to me ), I did have a slow leak that the air pressure monitoring system pick-up.

Don't really see the advantage of run flats?

Just about Tyres: X5 2007, 19" wheels , I scrapped the Run Flat's and installed Pirelli 255/50R19 Scorpion zero, load index 107 , $560.- each. It's fantastic very very smooth no more bumping all the time and very little noise. Now it is the 125k vehicle.Thanks to Conquest Tyrepower Adelaide, Australia.
