Hi guys,
I know its an old thread, but its in the same topic so might as well.

Will I have any issues if I run 255/40/20 & 295/35/20 set? Please advise. Thanks!

[Hasser]

no issues on mine......except slight rubbing on the rear with a fullload ie. 3 passengers in the back and load in the boot

I got a set of 20" vorsteiners.

9 at the front 10.5 at the rear

and am running that set up on stock suspension.

Hasser, did you realise that the OP was asking for advice with higher profile tires? 255/40-20 front and 295/35-20 rear.

I think you run 255/35 and 295/30?!

[.BMW.]

255/40 and 295/35 are possible on F10 but the wheel offsets, are crucial, especially the front. Or else the front tires will rub.

This photo show 255/40-20 on 8.5x20" wheels with ET32, less than 1/10" clearance with the car on the lift and rubs with the weight on the wheels.



The front offset needs to be around 25-27, lower and the tire will rub the fender liner and higher the tire will rub the steering knuckle.

295/35-20 rear will probably fit, but I wouldn't use wider wheels than 10" and offset close to 40 or maybe a few millimeters lower.

Don't take decision only based on my advice, I use a square 255/40 setup not staggered with 295 rear tires. Also remember that these tires are about 5% taller than OEM sizes.

Oh yeah. Good point. Missed that slight technicality

[PJinCA]

my question about that tire size would be: wouldn't that affect the speedometer? that would be outside the typical 3% of oem diameter, isn't it?
I run the following sizes:
front: 20x8.5 with 245/35/20, et 19
rear: 20x10.5 with 295/30/20, et 35

Yes these tire sizes affects the speedo, but to the better.

With OEM sizes the speedo show about 2 mph higher than actual speed at 60, with 255/40-20 the error will be less than 1 mph (on the lower side).

a little off topic here but I need some education. I ordered a set of rims and obviously I took the advice of the "professional" but why 30 wall in the rear and 35 in the front? I haven't dropped my car yet but I kinda thought after I installed them that more rubber would have reduced the gap.
any reasoning behind this?? thanks

front 245/35/20
rear 285/30/20

[.BMW.]

First number is section width in millimeters, the second number is side wall height in percent of section width.

I.e.
245 x 0.35 ~ 86 mm
285 x 0.30 ~ 86 mm

[xxpanipuri]

that should work just fine. depending on offsets you may even be able to go 255 and 295 Michelin PSS

thats what i did f/r, no rubbing at all

I think that might be a little tall but I am running 255/35/20 and 295/30/20 on OEM 303m with ACS springs. Math says it is 1.3 percent larger then stock size if I'm not mistaken but, No issues what so ever. fills some of the gap that was left. I love it and plan on running the same when I need to.

Kumho ecsta ps91 btw

Ditto here. I want to run 245 / 40 in the front and 285 / 35 in the rear.

is the Ratios ok 40 front and 35 rear?

[aikhan4]

Running 285/35 on my vossen cv5 lowered on Megan Coilovers, no issues

Hi,

I am interesting for JR21 wheels. Which rims and tyre dimension (front and back) would you suggest for my BMW 5 F10 (non M version, 525d) ?

It would be great if will fit 20x10 front and 20x11 rear

Thank you.

I run this same set up on Forgestar F14 20" super concave w Michelin Pilot 4S lowered on KW no rubbing.

[5fifty]

I am running 20x9 and 20x10.5 with Michelin Pilot Sport
255/35-20 and 295/30-20

No rubbing, Stance looks amazing with Dinan Springs and Ride Handling

Any chance you can post a pic? Not the entire car... just wanted to see the clearance with your wheel/tires set up with the Dinan Springs, which I know are supposed to be a .5 inch drop. Looking to get 20’s as well. Thanks in advance.

Running 255 + 295.

What width and offset are your front wheels? Are they flush? I'm trying to decide between 20x9 et20 and 20x9 et35 with 255/35-20 tires in a square set up. I think both will fit, just dont know how flush the et20 would be...

Hi, this is the problem with my choice of wheels, because I am scared if will not fit well.
Could you tell me parameters for 20x10 wheels?
ET? Tyre dimensions? etc.?

Thank you.
