2011 BMW rim suggestions

Hey, recently I found out that both my rear rims were cracked and that both my front rims were bent. After experiencing a loss of air, I decided to buy rims now. I’m looking into forged rims 18inch by 8 front and 18 inch by 8.5 in the back. I really would like forged rims but I can’t seem to find any that are a reasonable price. I am only able to find over 650$ per rim and I wanted to know what site or rims do you recommend. I would like to spend up to 1000-1600. For the set.
 
Is there any reason you don’t want to go to 19’s.... there are various genuine O.E. BMW forged wheels that will fit at a fraction of the cost of ordering new aftermarket forged 18’s (which tend to be very expensive).

No compromise on ride quality compared to 18’s with the right tires either.

Yea I kinda wanted to keep the same size so I don’t need to repurchase all new tires since 3 of my run flats r in new condition
 
The tires I currently have are the 255/35RF18 for rear and the 225/40RF18 for front. I wouldn’t mind a 19inch rim if it was to fit these tire specs. Otherwise I’ll stick with 18 inch rims

You have cracked rims and you want to reuse runflats on new rims? :cry:

Lmao my other wheel does not leak any air at all and are new. It would be a waste of 300$ to throw out a perfectly fine tire. If it came down to it then I would replace the two rear tires and keep the two front ones.
 
I've got some split rims - no idea if forged or not- complete with 3 decent runflat tyre for sale(other at 3mm) no problems with leaks /bent/ cracked rims etc V spoke 294 18 " taken from my 35i E89. Wheels 11 years old but you wouldn't know itFull details here

These are the same rims I currently have on my car. They are cast alloy wheels. Thank you for the offer but since New York City roads are horrendous, I think forged rims are what Ill need to last another 30k+ miles on these roads.

I'm not suggesting throwing them out but I'd certainly be getting them on ebay and getting rid

This 100%, why look at very expensive forged rims to enable the continued used of the worst possible type of tire on a Z4?

You won’t find new aftermarket forged Wheels at low cost, it’s likely to be cheaper to buy new non-forged wheels and non-runflat tires and sell what’s on the car currently.

You can’t fit 18’’ tires on 19’’ wheels :? :cry:

I mentioned 19" wheels because I would just buy a new set of tires for the car if it was actually worth buying them. Also, what do you mean by the worst possible type of tire on a Z4. Are you talking about run flats in general, and if so, what tire would you recommend?
 
Yes, runflats or ‘run-craps’ as they get called here in the U.K..

Fitting non-run flats transforms the ride on a Z4 as you pretty much sit over the rear wheels (not literally obviously). It’s much more compliant and you’re much less likely to damage your wheels :thumbsup:

You need a small compressor and a couple of cans of tire foam, vast majority of forum users here ditch the run-flats.
 
Admend, hello..

IMHO if you have it that bad with potholes in NY then you need really two sets of actions..

You need to go to 17" wheels as they tend to be stronger AND the appropropriate tyres which have a much bigger sidewall.

We suffer where I live in the Scottish Borders with serious pothole damage, in part to longer, colder winters but mainly due to logging..by the time 2,000 40 tonne movements have gone through on a small road the destruction is significant.

So I run 17" alloy wheels with All Season tyres in winter and 18" wheels with pure summer tyres in Summer.

Over 4 years I've not had a cracked/dented rim despite extensive use in winter often at speed.

Most suppliers of alloy wheels here in the UK have standard disclaimers on using 19" wheels with low profile rubber on damaged roads.

Your problem is excacerbated by use of run flats as they have much stiffer sidewalls which transmit the shock of a pothole much more severely.

Forged wheels don't buy you anything as yes they are on a pound for pound weight stronger, but all that happens is that they reduce the weight for the same strength as a cast wheel..ie no improvement in shock resistance..just a lighter wheel, which does have other benefits.

Thank you so much for this response! I understand where you are coming from about the 17 inch wheels because I was told the same thing, to increase the amount of tire which will help with potholes. I will probably stick with 18s instead of 19s because like you said, I would need to reduce the amount of tire for the 19s to fit properly and I can't do that here in NY. I will just buy flow forming rims 18 inch but what tire brand for all season tires do you recommend?
 
Tyres as you may by now realise is very much a personal thing!

These guys did a good piece of work..not sure all the versions are available in the US?

Depends on what your bias weather wise is..

The Continental are more snow orientated versions

I use the Goodyear Vector Gen 3 which has a OK snow good everywhere else review

The Bridgestone Weathercontrol A006 gets very good reviews apart from snow

The previous masters Michelin this year lost out to the other guys..they have a new version coming out to put them close to the top but I don't think that's yet available.
 
I have one more question. Will 18x8 32 offset front and 18x9 35 offset rear fit the z4? I will be running 225/40 front and 255/35 rear
