Hey everyone,

Got some questions for the group around wheels and tires. My m60 has the 21" wheels and as well all know the tire selection for those is absolute garbage and there are no all season options at all. Living in Colorado I need at least some all seasons, so I am thinking through my options and want to see what others think or have done.

Option 1 - Go to a square setup with 255/35 r21s all around. This I think is my first option but there are some considerations here. First is technically for the 21" wheels they say tires should have a load index of 101 in front and 103 in the rear. All seasons in that size come with a load index of 98. Load index of 98 = 1653lbs/tire or 6,612lbs total. m60 max gross vehicle weight is 6,404lbs so about 200lbs less than the tires are rated for. To me this seems fine, as I will never load the vehicle to max capacity so I am not worried about that unless there is something I am missing. The problem here may be finding people to install them. I can try to find a small local shop to install them but I am pretty confident that the bigger guys like discount tire wont due to not being high enough rated on the load. Am I missing anything here? Hopefully as more heavy ev's come our tire options get better for the 21s.

Option 2 - Go down to a 19" wheel. I would stay oem. A couple questions here. The options I am seeing have the same offset front and rear. Will those work on the m60? Or do I need the staggered wheels with the different offsets? If I do the set with the same offsets, is it going to look weird in the rear with that offset? (difference is ~1") I can't find any actual pictures of cars with the 19s. Do they set the 19" cars from the factory up differently or am I completely over thinking this offset issue? Benefit here is much greater tire selection, cheaper, "proper" load indexes, and better ride.

Option 3 - Go to a winter set and summer set of tires. Really don't want to go down this path if I can avoid it. Winter set would be aftermarket and correct the offset issue above is my thinking.

I'm no tire pro, but since the online configurator for the M60 has no square option for tires (all the options show staggered choices) I suspect BMW doesn't want you to use a non-staggered setup. If you just want to see what square 19" wheels look like on an i5, you can use my car as an example. It's not an M60, but an eDrive40 looks pretty similar on the outside and mine has the 19" wheel square setup.

This issue is one of the few why I chose to go I7 over I5. I think the 21 inch wheels look great on the I5 but there are absolutely no options to use those during the winter because there are no (as in not one) winter or all season tire option. The bigger issue is, as you mentioned, the load index....and I don't want to mess with that nor should you by putting on tires with a lower than OEM load rating.

All of the tires that could fit don't have a high enough load index....THAT'S the issue. On the i7 with 21 inch wheels, the tire sizes are slightly different than the i5 and the OEM 21 inch tire size for the i7 only has 1 all season/winter tire. However, there, you can change the i7 tire size a little and still be OK because all of those new tire sizes have the correct load ratings.

My dealer here has not once spec-ed a i5 with 21 inch wheels for this very reason.

So, your best bet is to use the 21's in the summer and a winter set of 19 or 20 inch wheels.

My Plan once I move back to WA is to get a set of All Black 19" rims with winter tires, then put Summer tires on my 20" rims and swap them out twice a year.

Hmmm well ok thanks for the replies everyone. I guess I will start looking at aftermarket wheels

That’s what I normally do. Winter was mild last year, only 2 snow days and it was light. I kept my 20” All Seasons. I will see what is expected this year. We have rain today, but the summer has really been extended. Not sure what winter will bring.

Just for everyone who runs across this thread in the future, please check load ratings on aftermarket wheels you are looking at. Most that I am looking at are bellow even the 98 load index tires that I was talking about before so if you are worried about going to a 98 load index tire you should definitely check wheel load ratings.

I cant remember all that I have looked at but here's some:

HRE - None of their flow form wheels. Rep told me 675kg (~1500lb) per wheel rating

Rohana - Couldn't find any

TSW - Mixed bag. They actually list load rating on their website which is nice. Some that do though are the Sebring, Lasarthe, Canard (20" only, not 19") for whatever reason it seems like their cast are higher rated than their flow formed.

Konig - Mrk1 no, Ampliform no, don't have a ton of sets that fit anyways, stopped looking

Enekei - No

Weds - Couldn't find load ratings. Didn't contact because I also could find a set I liked that would fit.

Vossen - HF3 and HF5. These are my preferred at the moment. Contacted for load ratings, will update when I get them.

Neuspeed - None that I saw

Niche - Mixed bag again but more do than don't if I remember.

Just wanted to give everyone an update and share additional information.

Contacted Vossen to find the load rating of the 19" HF5 and the first reply was that their wheels are rated to over 750kg. This is on the low side of acceptable for me, so I followed up the next day with the chat and asked if there was a style or size that had a higher rating. This time I got the reply that all of their wheels are "rated for well over 815kg".

Even with conflicting answers I figured screw it and order 19" HF5s with tires mounted from carID.com. I wanted to get them delivered with tires mounted because I'm lazy and didn't want to figure out hauling a set of wheels and tires back and forth to a tire shop. I chose carID because they have good google reviews and I was avoiding fitment industries after not hearing great things about them. Got a follow up email from carID saying they talked to Vossen and they won't fit. Strange as they are marked as "Guaranteed Fit" on their site and almost identical offsets to stock 19" wheels. I asked why they won't fit and was told the front wouldn't clear the brake calipers and needed a spacer or I could go up to the 20's which would fit. I said ok what size spacer, if it's a few mm then that's fine. Comes back and says actually that was a lie and Vossen says the caliper won't clear the barrel. Ok fine. I asked what 20" option are they recommending because the offsets on those do not line up super well to stock. Never got an answer but instead he tried to sell me a wheel with a load rating below the GVW. When I pointed that out, he basically said trust me bro they said its fine....At that point I was tired of both carID and Vossen giving conflicting and non-answers so I cancelled the order. It's been a week and still don't have a full refund. If I don't have it next week I will issue a chargeback on my card. I find it ridiculous that they can pull the money out of my account in minutes but can't return it in a timely manner.

So, I decided instead to go over to tirerack. They don't have as good of a selection and especially choices in stock (was worried about getting them before the snow starts flying), but I bought the O.Z. Racing Hyper XT. The setup tirerack has for the i5 is pretty aggressive with a 20x10.5" +41 rear wheel. I was worried about tire fitment and messaged them, and they said yeah no worries, order what tires you want and if they don't fit then your local discount tire will swap them out no charge. Ordered and they were delivered 2 days later. 285/35 R20 in the rear and 255/40 R20 in the front. Wanted to keep the stock 21" tire widths and 275 on a 10.5 wheel wouldn't look good in my opinion. 285 is barely enough but not sure I could fit a 295. Customer service and experience there was night and day different, only wish they had a little better selection for the i5. Also wish they would have come with black lug bolts but you can't win them all I guess.
