Re: Changing Rims
whats your current set up?
In general, running larger rims will decrease the sidewall size which will make your handling slightly sharper and ride a bit harder as there is less play in the tyres.
Run flats usually have hard sidewalls compared to non run flats. The effect of this is that the ride should be a little more compliant. Also, the compounds used in run flats are rather hard compared to non run-flats. Hence you might be able to get more traction and grip from switching from run flats to non run flats.

It'll improve your car's handling. Ride should be about the same seeing that you're on runflats (harsh) now.

Re: Changing Rims
Sure it will, it will improve your handling and road holding. Please let me share with you a mistake I made. I changed to 18" as you have also indicated but looking back, I should have changed to a lightweight forged 19" rim with matching tyres. It will look very much nicer and handle better. The lighter rim will also help you marginally with your initial acceleration. As for ride comfort, the 17" runflats are very hard so I believe there will be a minimal deterioration of comfort if at all if you are changing to a normal 19" tyre. Hope this helps.

Re: Changing Rims
I expected that too but because the 17" runflats are so hard due the the compound they use to make it last after a puncture, the difference is rather minimal. For the same reason, the tyre noise is also louder with runflats. Of course, it will also depend on which normal tyre you end up with. I use the Dunlop Sportmaxx and it is pretty quiet and I read inthe forum that Michelin PS2 is also quiet. However, as to which tyre to use, that is a whole discussion on its own but if you search the forum, you can find several threads on this which can help as well. Well in the end, it is up to you but just wanted to share with you my personal experience with my mistake. I feel that the wheel well for the E90 is very big and so an 18" does not fill it adequately. Anyway, your call.

Re: Changing Rims
Oh yes, agree with hitmee, must lower ride to make it look good but that will again affect your ride comfort slightly. As for offset, I can't remember what mine is. Any rim gurus can help here?
Anyway, it you do decide on 18" please consider my 18" BBS CH. PM me if you are going that way. Thanks.

Re: Changing Rims
19" Rim.....
Put on some good tyres like sportmaxx, bridgestone or PS2, dont spend a fortune on rims n giam-siap on rubber( I dont mean condom)...
lower the damn car with Eibach springs.....
replace the shocks with KONI FSD.....
Your E90 will look like a E92 Coupe from far after that. All the above recco-ed by fello hiadess on this forum and until today i have no regrets. Tomolo I am going to cheong to genting again to try my luck at the casino. Am crossing 2nd link at 6.30am ...anyone going up as well? if I kena jackpot there I sure come back and change to a set of forged rims.

Re: Changing Rims
am on the lookout from upgrading mine from 16 inch stock to 18 inch rims for E46...
Some dummies question that I have:
1) don't need to lower ride rite?
2) don't need to change brake etc,
3) harder ride, do you mean it is less bouncy and u could feel the road more or?
4) the extra wheel (does people normally buy an extra one to match the new size rims install vs still keeping the old spare ones in the trunk (which is not usable as it is of a different size 16 vs 18in), how do bros overcome that.
thanks in advance for the tips before I slowly venture into changing my rims

Re: Changing Rims
1) No need if you choose not too, but will look much much much much better if you do.
2) No need cos you must be using stock brakes if you're asking this.
3) Yes, you will definitely need more road. You can overcome this by changing your shocks to Koni FSD's
3) Your spare tyre will till be useable. It's not meant for you to drive fast or for a long time with. It's just for you to get to a tyre shop ASAP so that you can still reach there to solve your puncture. Even your stock rims is already bigger than your spare. No issues there.
Like what a few people here said, go 19"s once and for all if your budget permits. It will make a HUGE visual difference compared with 18"s...

Re: Changing Rims
Offset figures are not fixed for a particular car. Typically, deviation of +5 to +7mm from the factory measures are acceptable.
For your car, the stock offsets should be +34 front and +37rear for 8J and 8.5J widths respectively so u work it out from there. Most likely than not, u will be getting 8.5J all round if you are not going staggered so look out for offsets ard +35 all round..swee2x
If u want staggered set up then must play with the offsets n widths to ensure proper fitment.

Re: Changing Rims
Hi TripleM,
Need your advise, What do I need to do to make a set of rims from an E46 go onto an E90? Looks a little sunken into the car body both front and back and the back already has a 10mm spacer. Is it advisable to carry on using these rims on the E90 but perhaps put 20 mm spacers in the rear and a 10mm spacer at the front? Will this affect handling, alignment or stability of the steering wheel? Appreciate your opinion on this. Thanks.
