Do you know the offsets on those rims? And you'll be rubbing with that 255 up front, most likely. I can't help you without knowing the offsets, however.

 

Thanks for the info everyone! The wheels were put on this past weekend so I will take and post pictures sometime this week. The front is rubbing a tiny bit with he 255s so I will just change them up to 245s when I lower the car in a few weeks. The 285s in the rear are working out very well with no rubbing at all but I am having the fenders rolled in all 4 corners just in case anyway. I'm definitely very happy with the way everything turned out and hope everyone will like it as well.

 

What are the offsets on those wheels, and are they hub-centric (72.56) or did you have to use hub-rings?

Post some pics up

 

Dude your 05 530i has absolutely NO torque and hp to spare with 225hp and 200 foot pounds you cannot afford to lose any and with your wheels you have done just that. Why is so many people giving incorrect recomendations with tires sizes for 20 inch wheels.

For one your 255s and 285s are too big and will rub when pushing the car at all. The recomended sizes to maintain the same rolling diameter which as posted elsewhere not only keeps torque/hp the same but keeps the suspension, shocks, struts chasis in balance since it was designed for a certain diameter rolling .

Stock is 245-40-18.

245-30-20 and 275-25-20 is the setup you need to have no issues or problems and not lose torque due to having an INCH bigger rolling diameter.

I calculated it on the other thread but you are losing 4-5 percent torque with having an extra inch in diameter of the wheels. You are basically adding a gear into the whole setup and as everyone knows, taller gears mean less torque.

So you have effectively lost about 10 foot pounds of torque which is a lot when you only have 200! but to each their own.

 

I always appreciate the input of others when it comes to cars since I have always been into cars my entire life so thanks; however,

Number 1, I did not purchase my 530i for speed, horsepower gains, or to go fast because I bought this car as a daily driver that looks good.
Number 2, my previous car had 767whp so I thought it was time to just get a car that I can relax and cruise in.
Number 3, when I start to miss horsepower and going fast which will probably be sometime in the next few months I will go to the dealership and
purchase the Porsche that I am planning to get and then worry about horsepower and torque again.

But like I said, I always appreciate others opinions so I hope you will appreciate mine. My plans for this car are simple, make it look good and not worry about horsepower or speed.

 

Hey Frank,

The offset for the wheels are 18 for the front and 20 for the rear. The wheels are not hub-centric so I had to use hub-centric rings. There is absolutely no rubbing on the rear at all and the front rubbing is very minor. However, even though it is minor, it does aggravate me so I will be switching those out to 245s when I lower the car in a few weeks. I will have pictures posted up at the end of this week because I am away on a business trip. Talk to you soon man.

 

The offsets for the wheels are 18 for the front and 20 for the rear. As stated above, absolutely no rubbing on the rear and very minor up front. But I will still change out to 245s in the front when I lower the car. Thanks!

 

Thanks man. Any idea on the weight of the wheel (w/o the tire)?

 

Sorry for the late reply. I have been away on business for the last month and just got back. I had a Supra which put down 767whp on Race/Meth. I've been looking at the Porsche 911/997 Turbo and just absolutely love them, especially if I were to send the car over to Protomotive. As for the wheels, I'm not exactly sure how much they weigh without the tires; however, I will definitely find out for you. I will post pictures up sometime this week. Talk to you soon man.
