Wheels and Tyres
Frequently Asked Questions (FAQ)
Updated: 1 May 2007

Introduction

Hi everyone. Members are often asking the same questions on wheels and tyres so I have compiled the following FAQ for this topic based on what members have posted.

1. What are the standard wheel and tyre sizes for BMW 1er?

7JX16 ET:44 .......... for 205/55/16 tyres
61/2JX16 ET:42 ..... for 195/55/16 tyres

7JX17 ET:47 .......... for 205/50/17 tyres
71/2JX17 ET:47 ..... for 225/45/17 tyres (only rear)

71/2JX18 ET:47 ..... for 205/45/18 tyres (front)
8JX18 ET:49 .......... for 225/40/18 tyres (rear)

2. What do the different BMW OEM 1er wheel styles look like?

See this .

3. What is the stud pattern for the 1er?

pcd is 5/120

4. Can I replace my RunFlat Tyres ("RFT") with conventional non RFTs on my BMW OEM wheels?

This is a highly contentious issue. From a practical perspective, the answer is yes, however 1er owners should satisfy themselves regarding:

a. Your BMW warranty. It appears that using non RFT at least voids your BMW warranty in relation to anything related to the use of non RFTs.

b. Your insurance. ie that your insurance company does not consider using non RFT on a 1er to be a modification which voids or otherwise creates an exception to your policy. The general consensus appears to be that non RFT are not considered a modification to your 1er that changes your insurance.

c. Legal requirements. Are there any relevant legal requirements in your jurisdiction to carry equipment to deal with any flat? Regardless, owners should consider how to deal with flats from a practical point of view.

d. Your safety. Cars fitted with RFT generally have greater control after any (especially sudden) loss of tyre pressure at speed.

The run flat tyre indicator works fine with non RFT as the 1er uses an . Don't forget to reset it per the 1er owners manual.

5. OK, I've decided to get non RFT- what do I do about any flat tyres?

Try using the BMW Mobility Kit (see ) or use a similar third party product.

6. I cannot find 18" non RFT that are identical to OEM spec- what can I use?

Widest specs that keep the speedometer as accurate as possible and understeer/oversteer bias with no guard rubbing is 225 40 18 front and 245 35 18 rear (see ). Those wanting more oversteer bias may consider 225 40 18 for both front and rear.

7. Will 255 tyres fit on the rear?

Tyre manufacturers generally specify that 255 tyres are too wide for all wheels up to and including 8" in width. However, TUV has certified some 255 tyres for use with 8" wide wheels. See . Members generally report no rubbing issues for 255 tyres on the standard BMW 18" 208M wheels.

8. What tyres should I use?

Depends on your priorities. See for a recent tyre comparison using the 3er.

9. What non RFT are BabyBMW members putting on their 1ers?

Pirelli P Zero Rosso
225 40 18 and 255 35 18 (Roofer)
225 40 18 both front and rear (Vasalis, )

10. Where can I find more info about tyres?


I'm happy to add any other questions which the forum is able to work out so hopefully we can make this a fairly comprehensive document that will be useful to all. Please post specific edits as a reply to this topic and I will amend the above based on what is accepted.

As always on BabyBMW.net, all care was taken when compiling this information but people should satisfy themselves whether this is indeed appropriate for them before acting on the same.

Thanks to all who contributed to this info and helped me compile it. Any errors/omissions please let me know.

cheers

Stupid question, but I need 4 new tyres for my 13 118d Sport on 17s. They currently have 4 X 225/45/17 on all four, but looking at the OP, should I not have 205/50/17 on the front?
What wheels do you have? :?
Standard Sport ones, look like this:

Does anyone know if the width size of an alloy can have an impact on the wheel bearing? My car has come back with an advisory for the front wheel bearing on its MOT, its running 8.5J aftermarket all round on my 2012 1 series. Its under warranty and this is covered, but wondering if BMW will kick up a fuss if the aftermarket alloys are directly related to causing the problem? Many thanks

The width - not really, but if the offset is different than stock it can add more load on to the wheel bearings. If you are running aftermarket wheels I would expect them to refuse the claim (although it's not a given).

I have a mild knock over bumps (suspect a top mount), but I'm going to wait until I've refitted my stock wheels (my winter rims) before having them investigate, why give them any wiggle room.

Hi,

I'm moving from a 118d m-sport to a 220d m-sport convertable and I'm assuming that my 118d winters - 205/55 R16 all round - won't fit the 220d m-sport as it has R18s fitted? So i'll need to source a new 2nd set of alloys for new winters, so could anyone suggest a suitable sized alloy for the 220d m-sport?

Thanks,

Your new R18 wheel size does not dictate brake size/clearance, which is the important aspect. I would trial fit a front and a rear before discarding your existing winter set-up.

Having just bought an '09 120d M-Sport (E8:cool2: that has aftermarket 18" TSW wheels fitted, I'm considering swapping back to original issue ones. Does anyone know if an M-Sport would have been supplied with staggered 18s when new, or would it have had 17s, with 18s as an option? Will any original 17s fit, same width front and rear, perhaps with slightly wider tyres fitted to the rears? I'm thinking that 17s would keep the cost down come winter - living on a hill, I always fit winters at the back end of the year.

I'd expect all BMW 17" 1 Series wheels to fit your 2009 120d. The original size probably would have been a staggered set of Style 207m wheels, with 205/50/17 front and 225/45/17 rear tyres. They're a pain to clean though, very spokey.

I'd be after something like a staggered set of Style 142 or Style 262?

I've found a set of 256s that I think would look good on our E88 M-sport, they need a refurb, but they're very keenly priced. Only 'issue' is that they're not staggered, just 7j ET47 all round. Are they going to look lost under the arches, or would some 215/225 (not sure re profile) tyres fill them nicely? Any tyre size recommendations gratefully received - as would be advice along the lines of 'don't get them, they'll look silly'! :lol2:

I have a set of 719M Jet Black alloys that I want to fit winter tyres onto. However I'm struggling to find the tyres that I want in the correct sizes.

If I stick to stock sizes, I can get Conti TS850P and Michelin Alpin PA4s in 225/40 for the fronts but nothing is available in the 245/35 rears.

However I can get 235/40 sizes.

Therefore what would be the preferred set up. Either:

225/40/R18 front with 235/40/R18 rears

Or...

235/40/R18 all round (front and rear) for a square set up?

Thanks.

They'd look a bit lost under the rear arches tbh. I'm guessing you'd prefer to avoid silly wheel spacers and longer wheel bolts?

Per the M-Lite FAQ Sticky, most people run a staggered set-up with 225/40/18 92 fronts and 235/40/18 95 rears.

Ah, OK. I've just looked at an E88 that lives round the corner from us - it's got one of those M-stripey grilles on, mentioned in another thread! Anyway, it's a 118d on 17s, and tbh I thought they looked OK......hmmmm, decisions, decisions....but yes, I don't fancy using spacers at all.
