pizzamoney wroteSure. I can’t imagine taking a x5 to track. I will roll over in first off chamber turn.I get your point well taken and that is in normal street use. Track/Road Course devours rubber on extremely heavy SUVs very quickly and a wildly different scenario compared to grocery getting, family outings, etc.

mmm50i wroteFB market place is a very good advice. You can easily get a set of 20 with tires for $2k if you are patient. If you don’t mind 19”, they are often seen for $1k a set.I have 22" summer wheels and 20" wheels for my winter setup. The 20s are much more compliant. Before thinking about trading in your car, I’d definitely try switching to 20" wheels for your summer or all season setup.
Since the whole point is to test out the 20s, I wouldn’t spend the money on new wheels and tires from the dealership. You can find a set on FB Marketplace for much less, and you can always replace the tires later if needed.
jajus198 wroteIf total out of pocket is 4k including all other charges (taxes, fees, etc..) and it will make you happy I would do it. Life is too short.Sorry that's the out of door price. They gave me 10% off MSRP with incentives for the new 50e. The total difference comes down to 4k they are also still offering my initial 1.99 apr so my monthly payment went change as long as I make a down payment of the 4k
Just make sure it's what you want. For me the 50e was not but it may be for you.

eelnoraa wroteToo funny. The only worse I can think of would be one of those Siverado or F-250s with a "Carolina Squat". Could you imagine needing to brake into a turn with one of those. Look out Louise.Sure. I can’t imagine taking a x5 to track. I will roll over in first off chamber turn.
jajus198 wroteWise choice. I had a 2020 X5 40i xDrive ordered new for 3 years. It had the 22's with the Air Suspension on it, and the ride was way smoother compared to the 2017 X6 with the 20's, which I had before. The 22s were normal tires compared to the 20s, which were RFTs.Decided against the 50e, I'll try to work a deal with another 40i + air suspension or I'll just downsize my tires of find a higher quality tire
But that air suspension... I liked that one pretty much. Now, I have another X5 on order, which should be manufactured today with the same 22s (full black ones this time) and the air suspension.

TechCTU wroteThat is debatable. We don't know what options the 50e has compared to the 40i. We need to remember that the 50e has a higher sticker price compared to the 40i without adding any packages/options on top.Sounds like you have a local dealer that will work with you.
Aseelnoraa indicated maybe they will let you take a loaner for a week before buying so you don't want to trade again. Best case would be a loaner without air and 20's then a loaner with air. You can try both.
The dealers are in the business to make money, not to be your friends.
tooloud10 wroteIf the X5 PHEV computer works the same as my current PHEV, the mpg reading is wildly inaccurate and an overstatement.TechCTU wroteI wouldn't overthink the charging thing, I plug my 45e in whenever I have the opportunity and just drive the car whether it's on gas or electric.The 50e works if you don't drive much or you will have to constantly charge your car, sometimes 2,3 times a day if you want electric. It didn't work for my use case. The 40, or 60 is the way to go until next gen tech comes around in a couple years.
I don't know anyone that tries to charge their PHEV three times a day--most just charge overnight and enjoy the extra miles.
I am averaging 32mpg over 60k miles because of the hybrid system.
One of my irritants with PHEVs is that they calculate mpg in the same way as regular cars, in that they simply divide the fuel used by the mileage travelled, assuming that all the miles travelled under electric power are free, which of course they are not. They take no account whatsoever of the cost of charging the battery.
In order to make an accurate assessment of a true mpg equivalent, I work out the cost of charging and convert that cost into how many gallons that would buy. I tend to add those ‘gallons’ to the actual gallons used and divide by the mileage to give a genuine mpg equivalent.
To give an example of how the overstated figure in the car compares to reality, my PHEV, which I charge at home after every use, generally shows around 70 mpg on the fuel computer. When I work out the true mpg equivalent once charging costs are added, that drops to around 40 mpg. One of the reasons that I’m looking forward to getting my M60i is that I will be back to a car that quotes an accurate mpg figure that doesn’t require a calculator!
As for wheel sizes, we cannot get 20” on the M60i in the U.K. I wouldn’t want them anyway as the 20” X5 alloys make a premium car look low rent IMO. The standard M60i alloys are the 21” Y-Spoke with run flats. I’m not a fan of huge alloys as they are so vulnerable to damage, but we wanted black alloys and 22” was all that was available to us. We really get ripped off in the U.K. compared to the U.S. Cars are way more expensive here with less standard equipment, we only get a 3 year warranty, and we don’t even get a spare wheel / tyre 🙄
pizzamoney wroteI drove the X5 at the BMW performance center track and that thing is surprisingly nimble with tons of power. It does not drive like a boat on the limit. Feels amazing on track. Obviously there are way better options for track day but it was no slouch.Too funny. The only worse I can think of would be one of those Siverado or F-250s with a "Carolina Squat".

- There are 21" wheels from BMW for your BMW; will improve perception of comfort vs 22" wheels
- Run flat tires can be harsh but that's still very subjective; run flat tires do get progressively harsher as the tread disappears with more miles accrued
- Go flat tires will improve comfort
There is no perfect answer. Only how much money one chooses to spend in pursuit of comfort.

Lgb0250 wroteIt only lowers 1.5" from normal to load level.No remorse per se. But, in retrospect wish I would have taken more time and bought an X5 with the DAPP and air suspension. Those 3” up/dn could help this old short guy while gettin in and out and I do miss the DAPP features that my Lexus RX gave me standard as part of their safety sense 3.0 Hate the idea of running boards but I may have to go that route.
jajus198 wrote275/35-22 + 315/30-22 = "Sportier", more firm ride.Hi,
I purchased a 2026 X5 40i about a month ago and I've driven about 800 miles without issue mostly.
The issue started recently when I started noticing a harsher ride and more road feedback than I previously was after a weekend trip over 60+ miles travel.
I have the 22" staggered wheels Adaptive M Suspension and no air suspension. Recently due to the harsher ride, increase in fuel costs, I'm really wondering if I should trade it in for a 50e or just get another 40i in the same build but with the air suspension. I'm bummed out about it. I did receive the latest 2026.03 idrive update but I'm not exactly sure what changed with the riding dynamics that made me so sensitive to it all of a sudden.
Anyway I paid a visit to the dealership they ran it through diagnostics and test drove it and found no issue of note although I swear something is different about my car. The tire pressure is sitting at 43front/47rear psi at the moment.
To make matters worse car is in the shop for ceramic coating this week but they haven't started my job. Not sure if I should pull it from the queue and just trade it in.
I know I could change tires down but I wasn't planning on that until there was a wear on them and now since my car hasn't hit 1k miles not sure what to do.
Financing currently at 1.99/60 mo. Promo has ended and now financing it back to 2.99 not the biggest deal but an additional complicator

There is some degree of performance vehicle DNA at the core of any BMW model. A person who considers the road charecteristics and manners of a 90s era Town Car to be the cats ass will likely not be satisfied with any BMW.
UK X5 Owner wroteSure, I’m aware of how it calculates but I drive a lot and much of my charging is indeed “free”—at least to me. That said, I do pay $30-40 extra per month in electricity at my home to charge.If the X5 PHEV computer works the same as my current PHEV, the mpg reading is wildly inaccurate and an overstatement.

I’m not gonna go do all that math to get the true numbers so my brain finds it a lot simpler to just think of it as “I pay about $35/month to get 32mpg while driving a large SUV. Considering fuel prices these days the cost to charge is basically a rounding error for me.
pizzamoney wrotei don't disagree. personally just tired of hitting the unavoidable pothole on a dark road. not very enjoyable.This is what would be expected with a BMW and not the water bed on wheels that some people are looking for and find desireable.

I’ve tried a PHEV as I didn’t want an EV with their range limitations, but have found it to be a compromise. Even though I can charge at home, I find having to charge it every night to be a complete pain. As with a full electric car, I never achieve the full claimed EV range, and when the battery is depleted it’s very heavy on fuel due to the added weight. I’m going back to a conventional engine with my X5 (M60i) but will probably go full EV next time. I’d like to think that it could be an iX5, but with the way that BMWs styling is going I fear that my M60i might be my last ever BMW, which will be very sad as I’ve had loads of them over the last 30 years 😞
UK X5 Owner wroteA few of us have developed spreadsheets for calculating the MPG and mi/kWh as accurate as it can be calculated given the tracking.

PunsGalore wroteI agree 100%. If you don't drive above 100 mph or haul heavy loads you can safely decrease your tire pressures. I had 20" wheels with Pirelli runflats on my X5 and when I switched to non runflats the ride did improve but not a lot but it's the easiest and cheapest thing to try. I would NOT trade now. You will lose at least 10-15% maybe more. A private sale would be a better route to take IMHO. I sold my X5 for several thousand more than I was offered by CarMax or Carvana.Not sure why anyone goes with the 22 inch wheels; get the 20 inch 740M style wheels, and it'll be much better. Heck even switching the tires to non run flats on your 22's will make a difference. Dont sell it
