Getting rid of the run flats
- Thread starter Nick7602
- Start date
Just to throw another grenade into the room............... I've heard reports lately of other manufacturers providing very good run-flat tyres.
It seems it is the Bridgestones that are the problem, not all run-flats.
Always have to go that one better Peter.
oke:

F@€£ing proof readers…f@£€king iPad keyboards :tumbleweed:
:evil: :rofl:Good morning Guys
Mmmm I have heard about the alloys cracking, which isn't good, will i guess have to get rid of those at some point to, but I desperately need tyres, superb and thoughtful advice Peter thank you as I really haven't a clue what works well with the Z, so its really useful to know, im not sure if a straw poll has been done before showing what works and what tyres to avoid…personally I just check EVO magazines findings to get an idea, that said every car is different.

As I said, for your car and probably until you’ve really settled in you could pick any of the following and wouldn’t go wrong..best to go to Camskill or Openeo and see what prices give what options.
My list FWIW for your car ..IMHO..in my personal order of preference taking cost into consideration
GY Assy 5
Conti Sport Contact 5/5P
Bridgestone Potenza Sport
Michelin PS4
Conti Premium Contact
Dunlop Sportmaxx RT2
Lots of other choices
For me the E89 with its front wheels waaayyy out in front I want something that gives me good feedback on the front end…the Contis were best for that followed by the GY..the Michelins I find ‘dead’ albeit they get rave reviews
Each to their own.

I think Michelins have slightly higher noise rating than Goodyears Asym.
So could be slightly harder and less grippy.
Reason why i have always stayed with the Goodyears last 9 years.
We seem to have lots of noisy tarmac in UK.
Occasionally you get a good stretch of road that shows quiet tarmac does exist.

I found on 2 separate E89s that whist it does affect the speedo reading on 235/35 19 and 275/30 19 at an indicated 55mph it true reading via
various GPS based devices was 54mph..at indicated 70 mph was 69 mph true. On 265/30 I assume it read fractionally lower..
I find this site an excellent place for great advice on all things tyres, https://www.tyrereviews.com the videos are highly informative. There’s sound advice on the forum too, however we all think our opinion and thus our choice is the best. You can’t go wrong with either Michelin, Goodyear or Continental, though I would suggest that you list the things that are important to you, not just that are important. The ones that are important to you and us tend to be subjective, feel and comfort, however, the ones that improve safety tend to be metrics that can be defined and compared, for example wet stopping distance or dry cornering grip. Take the Michelin MP4 and MP4s, one of the criticisms of the MP4 was lack of steering feel on a track, so the development of MP4S had a slightly stiffer wall, which gives better feel but at the cost of comfort and noise. Thus if comfort is more important than feel buy the MP4 or vice versa then the MP4S, however the differences are pretty small and I’m not sure I’d notice. I replaced old P-Zeros with 4mm of tread on the rear of my old SL400 because grip was atrocious, I replaced them with MP4S and the difference was night and day, it’s a common problem with P-Zero as they age grip drops significantly.
Tyre reviews make me laugh out loud, because even the best are based in part on pseudo-scientific tests and Mickey Mouse statistics.
Funniest of all, perhaps, is the way most of their final results are given in neatly arranged percentages, separating brands by 1% or 2%, with convenient clarity for reviewer and reader. Beautiful examples of results leading research.
The worst use drivers' data: 'Brand M is very good and 12.5% better than Brand C.' (Not included in this data is 'Mind you, I only drive the E89 3,000 miles a year. It had knackered Brand C runflats on it when I bought it, which I chucked away, and Brand M's the only tyre I've bought in the last 8 years ... well, Halfrauds had a sale on 'em ... and I never put new tyres on my previous car, the Corsa, anyway.') And so on.
Such fun.

Are runflats marked in some way to identify them as runflats?
I've got Bridgestone Potenza 19" - assume they are runflats but is there a way to tell?
