Summer tires for BMW 744 wheels
Hi All, new here as I just purchased and took delivery of my first BMW (G05) - in white, X Line. Looking forward to growing in the BMW community.
The car came standard with 19” 735 wheels, which are a bit boring to say the least. I’m considering swapping to the 744 wheels in contrast colour (seen a few of you guys running the full orbit grey versions here). Comfort and low noise is high on the priority list, but I really am not fond of the 735 wheels... which is why I’m looking at the 744s. The car’s air suspension will hopefully help a bit (don’t think I’ll run the route of non-factory spec thicker tires). Anyway, it seems like the standard tires to fit to the 744 are Pirelli PZ4s... Could anyone confirm if that’s the case? Can we choose to use either run flat or not run flats? I read somewhere on here that 21 and 22” wheels can use non-run flat, which they found to be more comfortable than 19” on run flats. My 19’s are currently on Hankook Ventus Evo3 which are quite quiet and comfortable (not sure if they’re run flat). Thanks! |

You can put runflats or non-runflats on any size rim. Remember since your car came with runflats you likely do not have a spare unless it was included on your build. As far as ride and comfort that is up to the different tires, you likely will notice a difference from 19" to 21" due to loss of sidewall and switching to a high performance tire. Be cautious switching to 21"s as you are VERY limited in tire choices and there is only one readily available all-season alternative.

Not what you're looking for but maybe consider the 738? 20" plus a very classic design IMHO.
Might be good enough in looks but also meet your comfort criteria

Thanks guys!
Don’t think I’ll consider changing to 738 as it won’t be much cheaper than the 744 when getting new, and I like the looks of the 744 much more. I could probably pick up relatively cheaper near-new 740M 20” wheels as they come standard on local 40i M Sport package cars, but then I’m not fond of putting M-wheels on my X-line either... TBH if the car came with 738’s, I wouldn’t bother changing though as I agree they look pretty classic! As I live in the middle of a big city, I’m not very concerned about getting stranded too much. Service stations or help will usually be quite close by to do a quick patch. Being new to BMW and run-flats... using a non-run-flat tire won’t void my warranty will it? I also did a more detailed search on this forum (rather than scrolling through the pages), and noticed this old thread: https://g05.bimmerpost.com/forums/sh...&highlight=744 It suggests the following are available (will need to check locally for stock): Conti Premium Contact 6 S Run Flats Front: 275/40 R21 Rear: 315/35 R21 Pirelli P Zero- summer Run Flats Front: 275/40 R21 Rear: 315/35 R21 Pirelli Scorpion Verde - all season Non- Run Flats Front: 275/40 R21 Rear: 315/35 R21 Anyone with experience/thoughts on these? Based on Pirelli’s website, the Verdes would have better comfort than the PZ4s. I’m not after performance as I’ve resigned to the fact the one in my spec (with air suspension) will never perform around corners like the Cayenne GTS I previously drove. One of the reasons for the change was for better ride comfort/lower noise. I noticed on Pirellis’ website it also has P Zero PNCS tires (noise cancelling system), as an alternative to its run-flat technology tires. Any experience/thoughts on these? And just another noob question - is TPMS add-ons necessary when purchasing a new wheel? Or are wheel caps and tires all I need to get going? Thanks! |

As for the other questions: can't answer all but I always switch to non-rft at the first chance I get. Never had any warranty issues. Not sure if you have a lease but doesn't sound like it. I'm sure things would be different for leasing. Also, you mentioned you have an xLine which was a relief. I went xLine as well as I didn't want anything sporty but it was starting to feel like I was the only xLine on the forum. Was getting a bit lonely haha

It’s terribly hard to find tire availability here..! All the shops are small independent shops who don’t even seem to be bothered balancing the wheels after a tire change... I’ll try and call the Pirelli distributor and ask about PZ4 PNCS and run flats, and the Verde. Those in the States are so lucky when it comes to anything to do with cars! And Tirerack website is blocked from access here. |

I'm just coming to this point where I want luxurious comfort with just enough punchiness to get around. X5 fit the bill perfectly! Hopefully you are able to track down a set of tires! We are seriously blessed with our many, many tire distributors. Even easier for a squared set (thank the lord for 20's)

I put the Verde non-run flat all seasons on. (they are the ONLY all season I cound find as you have found out). Expensive but quite happy with them so far. I have the spare tire option since I anticipated this problem. |

The X5 is fairly heavy, and if you plan to tow anything, you really want a wheel that is rated for the vehicle as well as the proper load rating for the tires as well. So, choose one that is listed as an OEM one for the X5.
Depending on the brand, you may find two that look identical, but what you need is one rated for XH weight, so it's not just the size that is important. I know for the winter tires I recently put on, the same model tire was available in two different weight classes, and the XH was more expensive, but required. Not all RFT are created equal, either. Some ride and handle about the same as their 'normal' equivalent and they just keep getting better. The first ones were really stiff. Many vehicles today now come with RFT so it's not just BMW. It probably costs about the same for four RFT versus four regular ones plus a spare, jack, and wrench, but the combination ends up saving space in the vehicle and weight. Less weight saves fuel. |

My previous vehicle (Cayenne GTS) had 275/35/R21 running on P-Zero summer non-run flats square. Amazing around corners and handling but also terribly bumpy and noisy. I think it’s more to do with the vehicle’s suspension tuning than the tires though. So I’m not sure what to make out of it with the X5 on air suspension. I’m on R19 Hankook summer RFTs from the dealer and its a significant improvement in ride quality over the GTS. For the same reason, I’d be eager to get something which could maintain as much of this ride quality if I do change to R21. Certainly don’t want to go back to the ride quality of the GTS. Quote:
I’ve been trying to find an OEM tire list to no avail... the thread I quoted above seems to suggest the 3 (Conti and 2 Pirelli’s) are OEM. That said, I’m tempted to diverge from it by opting for non-run flats over run-flats for theoretically better ride quality and lower noise. It’s terribly hard to find any reasonable discussion on this online! |

Have never been fond of Pirelli. Would recommend going with Pilot Sport 4 SUV for superior grip/performance in both wet and dry. May be slightly noisier but worth the tradeoff.

Yes, I think the designation is XL rather than what I said was XH (was thinking extra heavy, but it's extra load).
If you have a 45e, I think you need the XL, regardless, because of the extra battery weight. |

BMW tries to have at least two suppliers for tires. Doesn't always happen, as with the i3, there's nominally only one, but initially, their expected volume for that vehicle was quite low. Seems just recently, another has shown up. The X5 has much larger volume, so being stuck with only one supplier could really hurt production/delivery from the factory if there were ever a supply issue, that, hopefully, was restricted to only one vendor.

In summary, it seems like there are at least the following options for 275/40/R21 front and 315/35/R21 rear for the Style 744 wheels: Continental Premium Contact 6S run flat summer Pirelli PZ4 run flat or PNCS summer Michelin Pilot Sport 4 SUV summer Pirelli Scorpion Verde all-season Those Michelins mentioned seem well regarded. I don’t have access to tirerack website unfortunately (geographically barred), but from the following link comparisons, the Michelin and PZ4s each seem good in their class. https://alltyretests.com/michelin-pi...v-test-review/ https://alltyretests.com/pirelli-p-z...4-test-review/ Any idea why the PS4 SUV aren’t compared against the PZ4? Is it because the PZ4 are not SUV-specific, even though they can work for SUVs? I don’t think the data is directly comparable, but I could probably compare them against their peers... the PS4 SUV seem to be pretty quiet too... |
