Mein Auto: 335I
Issue with tires

I own a BMW 335I Sports. I got my tire recently changed at Sears Auto center, the mechanic over swapped the right tires and put the front tire on the rear and the rear on the front.

I noticed it and asked him to change it after a couple of weeks, what he did was he just swapped the whole wheel, i am now not sure if that is fine. Can someone help me understand this and let me know if i need to swap the tires or swapping the wheels are fine. Also let me know from where i can find if the rims are rear or front so that I can be careful in the future.

Tire Specs:
Front 225/40 R 18
Rear 225/35 R 18

Please help me with this, thanks in advance.

When you have different tire sizes front and back, the tires do NOT rotate front to back. If they are non-directional tires, they can alternate side to side on the same axle - otherwise they stay on the same corners they start on.

They need to return the car to original configuration...and you need to stop driving it until they do. Blowing up differentials in BMWs is expensive. I can't swear that the difference in size between a 35 profile on one side and a 40 on the other side will result in differential damage, but I absolutely would not try it under any circumstances.

If the rims are the same front and back, then you can rotate front/back IF and only if you run the same size tires all around. You can only cross them side/side if the tires are non-directional.

Arun,
Slightly confused. Your rear tires should be 255/35R18. Your front wheels are 18" x 8.0", and your rear wheels are 18" x 8.5" (8.5" is the rim width). Did Sears put the 225/40 tires on the 8.0" front wheels and install them on the front? Mount the 255/35 tires on the 8.5" wheels and install them on the rear? If not, they've screwed it up.

Have them refer to the "tire information placard" on your driver door jam and start all over again.

Thank you for all your reply. I am also equally confused and baffled with Sears have done with my tires.

To get the Specifications right -
The rear wheels are 225/35 and the Rims are 18''X8.5''
The front wheels are 225/40 and the Rims are 18''X8''

Now i am not sure which tire is one which Rim. I would like to know where in the RIM can i see the specification of the rim ? This way i can confirm myself and tell the Sears guys that they have screwed up the tires and ask them to get it all corrected.

Thanks a lot for your replies.

Arun,
This is rather astounding. If you READ DIRECTLY off the tire's sidewall...the size that is molded on it...do you see "225/35R18"? I rather think that you'll see 255/35R18 unless you've had some severely...erroneously applied tire from a previous tire change!

Did Sears fit a 225/35R18 to your REAR tires? I wouldn't put it past them! (although an odd size).

Your posts are getting more difficult to comprehend.

In the world of automobile maintenance, Sears Auto Centers have earned a very, very special reputation.

It is well deserved! When you trust your car to Sears, you can say: "It was a job, done."

Have you heard of TireRack?

Thank you for guiding me on how to read the tires specifications that was helpful.

The rear wheel has a specification 255/35 R 18
The front wheel has a specification 225/40 R 18
This after the wheels were swapped yesterday.

Is the size of the rims same from front and rear ?

If they are then my car is fine and I don't have to worry. If not I have a doubt if they have put the 255/35 R 18 tires on the front rims and vice-verse.

This is a difficult question to answer quickly. But in this matter, Google is your friend! Recommend you explore how it can answer this and much more!

dont know about your area but here in illinois very few take their precious bimmers to Sears auto center !! Pls take to some bmw friendly wheel or indy shop. Anyway, the tire/wheel info is in the door jam (driver side). Get under the car with a flash light and see what all info you can read from the wheel. I think wheel offset and related info is printed on the wheel. That way you will know if the right wheel is the right place. The tire info is easily visible anyway..

Going to Sears is like going to Walmart for your tires. Guys make $10.00 an hour and have no clue what is going on. They just try to read what is on the computer and hope for the best!

Well i took it to Sears and the tire issue is resolved as far as i know.

But i learned something from this Sears is not a great place to take a good car. I went there since it was close to my house and they had the tires i wanted and they gave it to me for the rate i got it in tire rack.

Thank you all for the reply and helping me out in this issue, i found this website which is useful for finding the right tire size and the rims size the tires would fit in, thought i shall share it as it might be useful.
