Anyone find any light weight wheel for the i4 that doesn't cost both my arms and legs?

I found some super expensive BBS 19" that's forged for ~$5K, back ordered for 6-9months. No one could give me a better time frame.

I would prefer 18" but haven't found any that's reasonably priced ($3K for a set) and doesn't look horrible.

For reference I have a i4 eD 40 on order with 19" m sport wheel. Would like to get back some of the range lost vs the 18" and hopefully improve handling as well

I think if you check the range different between the 18” vs 19” isn’t that great at only 19 miles in optimum conditions. What you will fork out for rims and tyres you will never get back the cost in savings at the plug (so odd saying that instead of the pump) LOL

Maybe vossen? Hre? Or 305 wheels forged wheels

Yeah, the 18s that come with the i4 eD40 are ugly as sin. I'll never understand the gray/black wheel look. Just looks dirty like a 1970's car with missing hubcaps. I oped for the 19s as well but at the time of ordering didn't realize range would be affected. You would think since increasing tires size affects range BMW would have more options in 18s.

You're also going to lose some range due to wheel design versus aero wheels. Not sure you'll gain enough range to warrant replacing with $5k of wheels and tires

VS Forged or La Forged

The problem with the range is not 19" vs 18" it's rubber compound and contact patch.

You would probably be better off looking for a 19" tire with less rolling resistance.

The other issue you will have is finding a wheel with the load rating.

Remember this car weight 5000lbs and fully loaded with people and stuff you could get to almost 6000lbs.

This means you would want a wheel with a minimum of 1600lb load rating. A wheel with a lower rating is going to be subject to bending or cracking.

Just a thought.

Light wheel on a Heavy car. Probably can't be too light.

Contact patch should be same as the stock 18" I plan on running the same square setup as stock 18"

Found Volk te37 Dura are rated at 1518lbs. I rarely if ever have more than 1 other person in the car. This will be my commuter car. So they're plenty strong enough IMO. The problem of cost is still an issue, since they're $1100 a piece.

I guess no one else besides me is looking for light weight wheel :dunno:

I found plenty of Tesla folks running forged light weight wheel on their heaviest cars, eg S, X. :dunno:

I wouldn't run cheap light weight cast wheels but so far forged wheels seem to hold out on the Teslas.

Your problem is budget, not availability of lightweight wheels.

I guess I really don't understand the reasoning. Is it that you just don't want a 19" wheel?

A sticky 18" tire will have higher rolling resistance that an efficient 19" tire.

I recommend finding a 19" with lower rolling resistance.

It's not the 19" that's causing the 20 mile difference in range. And to be honest depending on how you drive 20 miles difference in range could disappear.

I think you are looking to spend money on something that doesn't make sense.

It's your money.

yeah usually the budget is always one of the issue just a matter of if I want to spend more not a matter of if I can spend more

unsprung mass is still unsprung mass and 18" wheels are lighter than 19". Not like I'm going to put R compound tires on the 18" so rolling resistance shouldn't make a big difference. also 18" tires are lighter and cheaper than 19" tires.

long term makes more sense to me personally to go with nice looking/light weight 18" vs 19" :dunno:

having said this, I haven't found a reasonably priced 18 or 19" forged wheel so I may give up on this endeavor

You right the unsprung mass is greater on the 19" combination, but I don't think you are going to notice a difference. Maybe in ride quality if you didn't get adaptive dampers.

I think overall range isn't affected by the weight of the tire/wheel because this car weighs so much anyway.

I can understand if you want 18" wheels.
When I had my E90 people were split on 18" or 19". I went for 19" on my E90 as that's what BMW had as a sport wheel.

For this discussion though, my car on order is an M50 with 20" wheels and fender arch extensions. I want as much grip as possible.

We've just started adding some wheel choices in our online store today, but we're in the UK. Contact AC Schnitzer US for your prices over there.

Choices are:

19" AC1 cast 8.5J front and back (12.8kg each)
20" AC1 cast 8.5J front (14.1kg), 10J rear (15.7kg)
20" AC4 flow-formed 8.5J front (11kg), 9.5J rear (11.9kg).

All have sufficient load rating for the i4. No tow bar allowed though.

Just my 2 cents.

BMW spends a good chunk of research and development dollars on the wheels they put on their cars, specially on the M variants and M inspired cars. The process is extensive, it takes BMW about half a year to design a wheel. If you ask their experts they will tell you each wheel is "designed to its maximum".

Any aftermarket wheel you get will be inferior to the OEM wheels you get with the car.

To get the range back over the 18" wheel/tire I suggest getting a.low rolling resistance 19" tire.

I personally don't think the 20 miles range loss for the 19" combination is something the OP should worry about. Having had 3 EVs before, unless you routinely drive to battery depletion you will never see that 20 mile difference.

It seems like the potential pro of added 20 miles to the range is significantly outweighed by the cons of added cost, lesser engineered wheels.

Not bad
