That sucks, are they 19/20? Plenty of nice wheels out there. Some of the BMW performance are really sweet . But the runflats screw them

You'd get £250 each for the three you currently have

I seriously think my replacement of suspension parts. Bushes, springs and ball joints is due to the st roads in the UK.

Some parts of the motorways in the country are dangerous at high speeds also the undulations and so on.

I remember hitting a crater at 70mph. Car was fked

LM25 is not a very ductile material. Hence, loading past it's 0.2% proof stress results in permanent deformation. That induces micro cracking of the grain structure. The wheel is now very subseptable to fatigue failure, cracking until complete failure. Unlike steel, aluminium will eventualy fail through cyclic loading. And it's an even worse situation of the wheel it heated during the 'straightening' procedure, thus annealing it.

Thanks for that, cheers

My car is 11 years old and on 18" alloys and 35 profile tyres. You'd expect the wheels to be like 50 pence pieces by now but they're surprisingly round (albeit kerbed to fk). It's a Leon Cupra-R with this style wheel -

40 profile on my old LCR (and in the picture).

I believe it goes something like this...

photographic evidence and a civil engineer's report of the pothole being above regulation size must be tattoed on the skin of a flayed jackal and nailed to a pole in the village square once this is done and witnessed by twelve local elders the council is then allowed a decade to repair it before any claims can be considered

I've bought cars with buckled wheels but in 30 years and over a million miles i've never buckled a wheel, no doubt due to the fact i rarely have cars with low profile tyres (never less than 55s and rarely less than 60s) and usually commercial tyres.

Come to Aberdeen(shire) how I've managed 10+ years without buckling a wheel yet is beyond me (well, not it isn't actually, although I must wind up a lot of people behind me as I weave about to avoid potholes (in my lane, of course, not excessively etc.) and slow down for unavoidable ones (again not excessively etc. IMHO))

Have to say I'm surprised that a buckled wheel could be repaired, anyone got one repaired and gone of to do 10000's miles/trackdays on them?

I'm of the opinion that many new cars are supplied with wheels in a size that makes them 'not fit for purpose' for general use in the UK.
Da bling is more important though.

What car, what wheel? Just buy a spare from eBay, plenty around. Chances are a lot of people will buy an aftermarket set when they buckle one at that price and have 3 left over,
Singles are normally £150 ish for BMW 19s in good condition.
It's a new 740d m sport, no second hand ones availible

Probably cos they are all buckled

Seriously 19 or 20 inch wheels with rubber band tyres and the state of the roads in the UK I'd have spec'd the car with more sensible rubber

My RRS is on 20s as standard. The extra harshness from my previous FFRR which was on 19s is very apparent. 40 profile compared with 55. While dropping in and out of a rut I've also bent the o/s/r enough to deflate the tyre - it's killed the rim on the inside edge. Fortunately this was the day before I'd planned to swap over to my winter wheels + tyres. But I still dislike how compromised it is for an otherwise capable off-roader.

Being as heavy as the RRS and with such power it must have large brakes? Surely it needs some fairly large wheels to fit around the calipers?

You've never driven around Sheffield then! You can't drive around them there!

19's are the smallest wheels you can get on a new 7 series

The council around here make sure the drains are blocked so the enormous potholes fill with water. Well, frequently half the bloody road as well.

My E38 is on 18's for the Summer and 16's for the winter and the ride transformation is dramatic when I swap to winter wheels - I'm pretty sure on 19's or 20's it would be awful.

The only reason for bigger wheels is bigger brakes and judging by what I see most cars with big rims don't have big brakes so it really is a fashion thing and lets face it if the manufactures also gets added after-sales of new wheels due to buckling then they aren't going to be upset. Time for people to start voting with their feet or requesting smaller wheel options to be avaliable.

We were in Essex a couple of years ago and went down Childerditch Lane (Warley/Brentwood area)in the dark - Couldn't believe the state of this road, absolutely outragous Real Craters! Ended up swerving across the road and slowing to 20MPH (nobody from other way)
Have they fixed this road? I immediately put in a strong complaint via Fillthathole as soon as I could.
