Wheels/Tire combo question

[gabrielh]

I'm pretty newb when it comes to wheel/tires sizing.
I have a 2011 3.0 with 17" wheels square setup 225 wide.
Car is all stock.
Trying to figure out if I should upgrade to 18 or 19" wheels. I see the popular 19" setup but I'm thinking in getting a setup with thicker tire and as flush to the body as possible. I daily drive the car.

What do you think of my setup?

BMW 437M replicas rims in 18x8.5 ET35, 18x9.5 ET35
Michelin PSS 225/40/18, 255/35/18

After trying a good few different set ups on both my E89s id say the above were virtually the perfect numbers Re the alloys themselves but 225 40 on 8.5js & 255 35 on 9.5js are a size under unless your car is slammed .

 

[gabrielh]

Thanks, so what size do you recommend?

Assuming not lowered & with E89s having a decent arch space then 235 40 or 225 45 fronts / 255 40 rear
Have you considered 19s ? With the right rubber there is little noticeable difference between 18inch + 19inch from a ride quality point

What is/are the benefit/s of 19s?

 

[gabrielh]

Thanks. Thanks. Yeah I'm considering 19"but recommended thickness is 35 front and 30 back and I'm affraid of the ride quality with that little tire. I think I read that 40 front in 19" might rub.
Also save couple hundreds $$ going 18" buy I don't want to regret it.

Well primarily your sports car actually looks like one as opposed to a coupe with 3 series wheels on
you stick to your 18s , ive tried both & 19s with non runflat 255 35 rears + 235 35 fronts means no deterioration in ride quality over stock 18inch wheels on runflats

There was no need for the My question was for information only. I knew people liked the look of 19s and just wondered if there were other reasons to have them, too.

Your answer - that 19s on non-RFTs ride the same (i.e. as badly) as 18s on RFTs - seems to be a high price to pay for that look.

Factor in 19s' cracking rims and the price becomes ... er ... even higher.

 

[gabrielh]

I ordered the 19" last night
So now, tire size...Look like 235/35/10 front is a given. What about the back? I see that the recommended setup is 265/30/19. 255/35/19 will work good as well?

Its a tyre thread, Buster is always going to be here with his opinion on 19" wheels

Throwing something odd-ball in, For summer tyres, currently Michelin PS4, I'm running 18" 8j ET30 rims with 245/35R18 tyre & 18" x 9j ET40 rims with 275/35R18 with 9j tyres my 35iS and absolutely loving it. I think you may struggle with 275s with a 9.5j ET35

275 35 on a 9j :? that's pretty wide rubber for that rim :? do they not look oversized ? any pics ?

 

[techathy]

Widest 35 profile tyre in ETRTO specs for a 9j. In terms of looking oversized on the width, if you've not got rim protection on the tyre it can do. No pictures, but will try to remember to take some over the hols.

Any particular reason why you went 275 35 instead of 255 40 ?

 

[techathy]

Visual balance with the front tyre width plus my car is pushing to 535Nm at the wheels.

So chosen simply for wanting most amount of rubber on tarmac ? how much does 535nm convert to BHP :?

 

[techathy]

245 at the front & 255 at the rear looked odd given the style of the rims (See photo thread, with 265/35s on the rear)
