sorry if this has been answered before, couldn't find a thread ...

has anyone switched the standard X5M front 21" wheels for 22" wheels? is there a reason this couldn't be done, in terms of the 4-wheel drive system, or balance etc?

i'm just thinking a 22" front wheel would help with the dreaded wheel gap, and surely swapping the front wheels for just a 1" larger wheel can't be an issue?

i'm booked in for a new MSS springs replacement next week, but just thinking about the wheel sizes being staggered ...

constructive comments welcome!

That's a lie.. I don't know of any horror stories about MSS Springs.

Please elaborate. I've only heard good things about MSS.

This is an illogical statement. That YOU don't know of any horror stories does not imply the above statement is a lie.

I had my few hiccups but they have been sorted out. Based on my experience, my analysis and the fix, you will have the same issue with HR Springs.

I have seen around to stay under 3% geometry change. The other day I read under 1%. The latter sounds quite extreme. I was thinking about doing the same and my worry is ending up with wheels you cannot find tires for. With the Oem setup, even if you change the wheel design, you are less likely to have this happen to you. That being said, you can use this tool and compare:

I have been eyeing a few Vossen sets and I feel very tempted to go that route, but still unsure about going 21 or 22 as well. Decisions, decisions!

Wheel size has nothing to do with gap. The net tire wall + wheel diameter will be the same. Only way to lower is via coilovers or springs.

you nailed it! All of us commented on the springs but didn't address the fact that sizing up to 22" (with OEM wheel size) doesn't make the gap smaller since diameter is unchanged.

ah, that makes sense, and i've heard that before on another car forum - i'm not very good on the "engineering" side of car ownership!

i wonder if having the wheels the same size would at least give an illusion of a smaller gap ... hmmm, maybe, but probably at best very marginal

thanks for the replies ... i was just thinking out loud really, and my car is in the shop on monday for it's new MSS springs, so hopefully that will do the trick

thanks all.

I love how helpful everyone is with questions and the such. Also to live quietly & vicariously through your's and everyone else's questions

I heard that there is a party here.

As other have mentioned.

No matter what size of wheels, the rolling diameter will still be the same as stock.

Yes, you can go oversize, but you'll have to keep the front and rear ratio the same since it is AWD system.

Downside in going oversize, you may rub on full lock, speedometer reading will be off, and may damage your transfer case.

Hope that help.

I have H&R in stock.
Do you want to put it on and gives us a feedback?

one of the "nicest" forums i've been a member of ... i exited certain "professional" / "day-job" forums due to the baffling aggression from some members, who seem to not understand that we're supposed to be a group of like-minded people who may disagree but don't need to fall out

thanks for that ... good to have proper experts give their view! i think my amateur idea has been exposed for what it is ... nice idea, but ......... no

Hello 155ND

I am over the hill from you here in West Yorkshire. I am getting an X5M at the end of June, and was wondering where you are having the MSS springs installed?

I can tell you I've ordered wheels larger in diameter expecting the same result MANY times but it made it worse visually lol. The tiny tire in the wheel gap made it look horrible. Then I finally lowered and now even the stock wheels look mint.

hi mate ... Autoworks Services, Swindon:

https://www.autoworksservices.co.uk/

Dale is the man ... BMW enthuiast, and worked with MSS to develop the X5M springs, and his own X5MC was the guinea pig car. I'll post up a review & pics on the other thread (MSS Spring - The 4x4 days are almost over!") shortly ...

[Alan l.]

Whats everyone take on running this combo for 22's all around?

295/30/22 Front
335/25/22 Rear
(Front and Rear delta -1.4%)

This was the setup that most people ran for the F15 and F85 without any issues but if you go by keeping it as close to stock variance as possible this is the size we should run:

295/30/22 Front
315/30/22 Rear
(Front and Rear delta +1.4%)

Here is the stock 21/21 combo for comparisons sake...
295/35/21 Front
315/30/22 Rear
(Front and Rear delta +1.00%)

[155ND]

hi Alan, i seem to remember one of your posts where you said that you thought the wheel gap looked less with the 21 / 22 wheels once the MSS springs were on ... this was exactly what i thought when i had the MSS springs fitted on monday this week.

this pic is the "before MSS" pic - my car is the left hand car before MSS installed, the right hand car is the shop-boss's car, with MSS fitted
