Installing winter tires plus rims

[Layton]

I have a 2002 325I with sports package (17" rims and performance tires) I ordered 16" winter tires and rims online and they will be mounted and balanced when they are delivered.

Is it easy to change the wheels myself or should I go to a tire shop? I realize I need a torque wrench to properly tighten the lugs but other than that is it just a matter of removing the old wheel and placing the new one? Also, if anyone knows what the proper torque is, could you let me know? I couldn't find anything in the owner's manual.

Since I'll have to do this twice a year, I'd like to do it myself to save time and money. Thanks.

you can change a flat RIGHT?
do that 4 times and you'll be golden.

Don't waste your money on a torque wrench if all you're going to do is put the studs back in.

Rule of thumb - tight as possible. Those are extremely strong studs and hubs - there's NO way you could put "too much" torque on them using your arms.

Though if you get a torque wrench you might be tempted to do other repairs! Like oil changes, or fuses.

Thanks for the help!

BE CAREFUL! Before you know it, you might find yourself adding your own windshield wiper fluid.

88.5 foot lbs is the proper torque. You'll need an alignment tool to help you mount the wheels because bmw's don't have studs to place your wheels on. You must tighten the lug bolts in a cross pattern, first one then the furthest bolt, then again until all five are torqued. Then double check each bolt again using the cross patern. Don't forget to check the torque one more time about 2-300 miles later to ensure everything is OK! After doing this changing a flat becomes a breeze! Enjoy your ride... [driving2]

You have an alignment tool in the tool kit in your trunk, but I have never had a problem getting the wheels back on without it. It really isn't that hard - the wheels still rest on the center hub surface. You just have to line the stud holes up with the holes in the rim. It isn't rocket science.

Buying a hydraulic floor jack ($50 - $100 depending on quality) will make the job go a lot faster, but you can also use the jack that came with the car.

One thing that might trip you up the first time - after you get all the lugs removed, the wheel might still be "secured" , you sometimes just can't pull it off by hand. The wheels fit pretty snugly to the hub and a little dirt and oxidation can make them stick together. A few good whacks with a rubber mallet (ON THE TIRE not the rim) while spinning it will free it up. If it's really stubborn you can whack it from the back as well, but don't crawl under the car to do this unless you have additional support besides the jack!!
