I see the usual bun fight has ensued!
Not everyone is going to like every single car that is made, there is some things i like about the car (F10) and others i dont but best to wait and see one in the flesh before you make a final decision. The wheels dont look that great and has been mentioned they look small for 19" but think this is down to the size of the car. Some people seem to forget that over the years cars are getting bigger and bigger if you go back to e39 its similar in size to an e90 now. Thats why it think the wheels are increasing in size, so that the car still looks in proportion. With smaller wheels cars can look under wheeled, the first time i seen the e90 when it was just released it was on 17's and looked like a big sofa on a wee set of castors it just didnt look right. @ Matt think its more to do with the suspension setup on the Sline Audis rather than the size of wheels. the crash and ride poor on 18" also. The 19" wheels on the e60 were a lovely wheel and the drove better with them compared to the 18" runflat in both a handling and comfort sense. The biggest problem for me just now is runflat tyres thats why i think i will move to another marque of car next... unless i buy a bmw that comes with normal tyres as standard. And dont say just change the runflats, if your spending £40k on a car it should comes with some decent rubber!! |

I thought things had shifted and now RFTs are an option on most BMWs?

No, RFT's fixed spec and they have over softened the springs on the F10 SE to compensate.

I have driven my car on 17, 18 and 19" wheels, and it does affect handling - I'm not making it up! Turn in is definately better with lower profile tyres - & best of all with RFTs. I think you should buy those 18" 162s you are after - they are the best SE wheel and will look great on your car and will improve the way it handles. You will notice this. If you get non-RFTs the difference in ride will be hardly noticable over the 17"s. |

jw - that sucks big time.
Wonder what will happen with the new 3er? Surely thousands if not millions of BMW customers have complained about RFTs? Have the inventors of RFTs got some dodgy pics of BMW and Audi Directors that they will threaten to sell to the media if their the cr4p tyres aren't used? I can't think of any other reason to use them. IMO the E9* is generally a big improvement over the E46 apart from the RFT tyres. In the case of E39 to E60, I think the ride REALLY suffered from RFTs - my inlaws 535d Touring was utterly hideous riding on them - so they sold it pronto. /// - if the radius of a 19" tyre is the same as a 17" one then why on earth do they "fill" the arches so much more?

Why didnt they replace them with normal rubber, transforms the car and the best thing about the e60 was it had room for the space saver, where the new cars dont..

Interesting about radii but surely tyres come with different profiles? It's not a set ratio. And go to a tyre dealer - the 19s look like truck tyres, the 17s don;t. You are also looking at fat rubber on 19s - say 265 so the profile has to be very slim to make it the same as a 17" 225/45. I may be wrong on this but I can't see how "arch filling" 19s are the same diameter as 17s. /// - I do like those wheels a lot - I saw a 325i with them (black E91 like that one) and really did like them but there are a few issues: 1) I have pretty new tyres all round - ditching them would be silly 2) I can choose any tyre I want - IMO CS3s are the best (Evo agrees too -they thrash all other tyres in this months issues) - even the tyres on those 162s are a lot harder to source. On 19s you simply cannot get the "best" tyres. The best tyres to me have more of an impact than the radius. 3) The wife loves the ride/handling of the car as it is - this is a proper petrol(or actually diesel) head wife who learned to drive in a new Scooby Turbo wagon and tested a new (at the time) Supra aged 18. 4) I love the sleeper quality of the car. A mate has been a few times to sort my bike out - we got talking about cars (he's not really into them at all) and when I mentioned that ours has nearly 300bhp he was utterly gobsmacked - I love that about the car. It's very very unusual I know, but the sleeper element is something I really do like and it's also useful down here in Cornwall where shoutyness is frowned upon. 5) Although they are small, I actually really like my wheels - slightly dished and with nice spokes and detail, the look pretty good from a angle IMO. Even Carlos likes them! They are "the wheels" on the Wonder Wheels box too... If the car had come with 162s though, I'd be happy but to pay £1200 for wheels and another £800ish for tyres doesn't really add up just to make it "look better" and slightly ruin the sleeperness (!) of it. They would be MUCH easier to clean though!! I also love driving the Jimny because it's SO uncool that it's almost cool. Especially in full hairdresser top down mode! Weird I know but then you all know I'm a bit special needs... Last edited by Em135eye; 07-02-2010 at 04:21 AM.. |

Remind me what you drive
For the record I like the new 5er. Yes it has it's quirky bits but, like most other BMWs (X1 excluded) it'll be a grower so may as well accept defeat now Definately needs BIGGER WHEELS though

http://www.etyres.co.uk/tyre-size-calculator.htm Put in your tyres - 225/45/17, and then 255/30/19. The difference in diameter is 2mm. My 17s are 205/50/17, which are actually bigger than the 19s by 1mm. Obviously the ratio can vary - but the idea is you make sure you get tyres/wheels that are the same radii for a given car otherwise the speedo wouldn't read right etc.! Bear in mind the diameter of any given wheel will change by around 12.8mm from full tread to legal minimum, hence the difference between 17 and 19 diameter above is negligible.

The great thing about the e60 was you had room for a space saver wheel if you choose to, you dont have that option now which is crap. |

Think Matt mentioned it was a while ago there was more nervousness (and lack of knowledge) from Dealers about changing RFTs to non-RFTs. Things have moved on a bit now. Lower powered E90's have non-RFTs as an option.

Irn - as Roger says, this was a few years back when dealers didn't know what was happening.
/// =- 205/50 is quite slim/high profile. Mine are 225/45 which probably makes a noticeable difference compared to 205/50s. Cheers for the link though! Anywhere I can find weights of tyres? Seems very tricky to find any. You are right though - 19s (255/35) are only 4mm larger than my 17s with 225/45s. Edit - tried 255/35 again and the difference is now 27mm compared to 225/45 - over an inch. Hmmm... Last edited by Em135eye; 07-02-2010 at 07:44 AM.. |

255/35/19 is not the right size and is TOO BIG for a E9x. The correct rear size is 255/30/19. You can also use 265/30/19 at the rear as it is almost the same diameter. The fronts are 225/35/19. The whole point is that you choose a tyre that keeps the diameter the same. My last car had 225/45/17s with Contis, Goodyear and Falkens, and I used to use the 205/50/17s on the same car. There was not alot of difference as the side wall is only 1.5mm deeper on the 205 over the 225 - they are pretty much the same size tyre, just a bit narrower. I chose them exactly because they are the same diameter as 225/45/17s. Regarding weights - these are not easy to come by - but the general rule is that tyres weigh less proportionally than wheels - hence moving to bigger wheels / smaller tyres to keep the same diameter is likely to increase the unsprung mass, but it depends on which wheels etc. |

I guess I just prefer smallish tyres - the same (but a totally different thing) on my MTB - I love 1.8" rubber, most get massively fat tyres.
30 is VERY low profile indeed. Just not my cup of tea at all. Cheers for the tyre size education though - clearly a hole in my knowledge. I think 18s are fine/good on an E9* - I think 19s are a step too far and for once an E90Post "player" agrees with me... |
