Tyre recommendations for the Mk7

[nat225]

In that case, there is still a leak. Either from the tyre or cracked wheel section or even the valve stem.

Mobility is one advantage of run-flat tyres, since the driver doesn't need to stop immediately if the tyre is punctured - but only up to a distance of 80 km, and at a maximum speed of 80 km/h. If you drive in excess of these requirements, then it's very possible to suffer a blow-out due to heat buildup (in excess of its design capabilities).

If you suffer a slow puncture on a standard tyre on a highway or motorway, and the TPMS system warned you as such, you could probably make it to the next exit, or even onto a tyre shop if nearby. However, if you suffer an instant deflation, you could probably only travel a few kilometres before the tyre quickly overheats and eventually fails.

Vehicle stability and control is another advantage, as run-flat tyres retain similar cornering and handling characteristics even when deflated. This is why the fitment of a TPMS is compulsory in most jurisdictions, otherwise the driver wouldn't be able to tell if the tyre was punctured or not and would continue driving until the tyre completely fails.

Maintaining control when a vehicle suffers a blow-out on standard tyres is a bit more tricky, but is manageable in many circumstances if you remain calm and don't panic. If fitted, the vehicle's stability control system can also assist to some extent.

Tyre manufacturers generally recommend fitting run-flat tyre on wheels with an extended hump (EH2 or EH2+) contour, which ensures that the tyre will not separate from the wheel under zero-inflation conditions. How strictly this is meant to be followed depends on the specific make and model of tyre.

I have seen many bmw tyres replaced with non run flat. Often cost is the main issue. I wonder if they do carry a flat tyre kit (in lieu of the RFT) as basically those bmw cars dont have spare tyre.

Righto. Two month ago my left rear tyre got punctured (which was afterwards told by my dealer) and TPMS sign pop up every week. I've got to inflate tyres every week.

Did you get it repaired & then reset the TPMS?

It wasn't cost, it was the crap ride.

They are pretty anal, so bought the BMW Jack kit & various forms of spare. I think 2 of them got the HSV wheel & had the centre bored out for the BMW hub.

Yep, I reset TPMS after every inflating. Dealer repaired tyre when serving this vehicle. After that, TPMS stays "quiet". Thanks for caring.

Right

your post read as if the dealer had pointed out the problem & you were surprised the TPMS kept activating.

Yesterday I lost a tyre on the South Gippsland highway — just as I ran into the almost perpetual rain band approaching Korumburra (had slowed to about 80K) I hit the mother of all potholes.

Spotted it through the murk at the last second, but too late to avoid dropping the RH front wheel into it, fortunately the rear wheel missed it.

A few K's further on the tyre warning light came on — had to pull over & change the wheel in the pouring rain,

The tyre ( 225/45/R17 91W) with barely 200K on it (the car's new and the first I've had with low profile tyres...) is a writeoff.

Couldn't find the exact replacement here either (Polish made Bridgestone Turanza) so near enough will have to be good enough (same make, similar pattern ER300 Turanza ECO from Japan.)

Wasn't the only victim either — just a bit further on from where we changed the wheel (my first ever use of a spacesaver, the inventor of which should be dangled upside down next the the guy who thought up speed humps...) the police were supervising the loading of a number of cars with flats onto tow trucks.

Had to complete the journey and return to Melb. on the spacesaver with the warning light on all the way.

What really irks me is that, despite the road from where I hit the first pothole to the end of the recently rebuilt section of road (the parts that were not rebuilt were fine — must prove something...) being riddled with huge holes, there was no warning — they couldn't have just appeared overnight and it is a major highway.

Incidentally, the Leongatha tyre guy who changed the spare from front wheel to back for me said he'd been swamped all week with tyres and wheels damaged on that stretch (wouldn't accept any payment for the job. either.)

At our destination I heard it had been a subject on the local radio that morning, and on our way home there were trailer-borne illuminated signs in evidence. I'll have a go at Vic Roads, but don't really expect to get anywhere.

As far as I'm aware, the maintainer of the road (council, state or federal government depending on the road) has a duty of care to ensure it's in a safe condition. Sounds like in this instance there's plenty of evidence to suggest that this wasn't the case. I've heard plenty of stories where motorists have been reimbursed the cost of replacement tyres and rim/suspension repairs due to bad potholes that weren't repaired quickly, so you may be in luck.

Tyre recommendations?

As per title i've got some 18's coming my way just wondering if anyone can chime in with some tyre manufacturer/model recommendations.

Am i right in saying the GTI's come with 225 /40 /18 as standard?

Thanks.

Mate, do a bit of a search/browse - done to death several times over with a cherry on top. Mk5, Mk6, Mk7, R, Octy vRS - all same, same in 18s

[nat225]

Go with linglong or bob jane allrounder if budget is tight, just make sure u drive extremely carefully at all times.

Else go with any of the premium brand and u wont go wrong

Have a look at Hankook Ventus 1 Evo2 or the Goodyear F1 Assymetric 2.

I've got the Goodyears on my R and the Hankooks on the Tig, both amazing tyres that you can get cheap-ish if you look at the right places

Ended up getting some Continental Contisports $219 a corner.

On a side note: I'm still torn between 225/40/18 or 225/45/18 anyone have any advise on this? Or does anyone have photos of them running 45's? Thanks!
