The shop recommence F:235/35/19, R:265/30/19 for tires

I have read some of the reply and post say that the tires spec of f10 is F:245/40/19, R:275/35/19

What is my choice of tire?

Last one is the best match.

245/40/19
275/35/19

I don't foresee any rubbing issue

[gapth8888]

Would i be able to lower it by 30mm? Will it have rubbing problem

Ps. I always carry 3-4 person(family car)

Anyone know how good is KW Spring?

[bobblehead]

Not at all. If you are choosing KW, then it's should be alright. If you want to confirm, you can contact your local KW reseller or tech rep in your local country, if none, then contact the US office directly for straight answer.

If your question is regarding adding spacers, then depending what's the thickness, then yes, it may rub.

Those wheel offset F:8.5J ET33, R:10J ET38, should be find with those tire spec F:245/40/19, R:275/35/19?

Sorry just for confirming i'm dont know much about wheel stuff

Thank for all reply will post some pic when it done

F: 19*8.5 et 33 is the factory spec for 535 & 550. Therefore, you are banged on. Tire: 245/40/19 is also the factory spec as well.

R: 19*9 et 44 is the factory spec for 535 & 550. Yours being 19*10 et 38 means you have 7mm less clearance from strut/suspension and your wheel extends outward by 19mm which is about as far as I like to see. The tire used on the stock staggered rear is 275/35/19, therefore, you are fine using the said size.


Last important note:
If I may suggest, instead of choosing R: 19*10, you should really consider using 19 * 9 et 44 for perfect matching with stock spec since HRE is customed made to your spec. and you can still choose 275/35/19 tire.

Sweet thank u so much

[bobblehead]

I feel R: 19*9 et 44 serves you better without any issue at all.

My wheel is already here do you think i still should go with those spec?

F:245/40/19, R:275/35/19?

Thk

[bobblehead]

Oh! tires of those mentioned spec. still the best fitment.

What tires are you going with ?

If $ is not a big concern, Michelin PSS is widely claimed as a favorable tires for our F10. However, it will need about 1500 - 2000km to break them in before they stick like glue on the road. They are alright (or just above average) in the wet condition.

PSS or PS2

Which u recommence?

Thku

I have PSS right now. Still breaking them in. Currently at 2700km and gradually they are a bit more stickier than as compared to brand new. I guess I will give it a 8/10 rating.

Other Ultra high performance tires I had in the past included GY F1 Eagle Asymmetric and GY F1 Eagle GS-D3. The latter is the absolute stickiest tire I ever had.
