I've just ordered some new 18"alloys and tyres for my bmw 318is coupe. Will I be able to fit them myself or does it need to be done professionally? I don't have a lot of mechanical experience but I am fairly competent and my friend has offered to help..

all you need is tires, rims, lube and tire irons and lots of time.
what the worst that could happen? scratch rim? or broken bones or teeth :)

I'm assuming that you've done your research to know that the 18" rims and tyres would fit your car without the need for rolling the inner fenders.
I'm also assuming you ordered the rims with tyres pre-mounted and balanced.
Then it's just a matter of jacking the car up, removing the old and installing the new.
With the E36, it's not the scratching of the rims you should be worried about. It's that darn jack design. Make sure your car is on a flat surface, engage park or 1st gear, and pull on the brakes hard. Chock the remaining wheels with wheel chocks or bricks. The E36 slide-in pin design jacks are notorious for having a high risk of falling off by allowing the car to roll either forwards or backwards. If you have an alternate jack such as a hydralic jack, I would use that instead.
Removing the wheels is straight forward, but when you install the new ones, make sure you tighten the bolts in a "star" (and not "circular") pattern. This would prevent uneven pressure on your rotors/hub. Also, the correct torque on the wheel bolt is about 75lbft. Without a torque wrench, you need to know how much pressure approximately to push by hand; yet not over-tighten. If you over-tighten, you risk warping your brake rotors after a short while of driving.

You need to have them done professionally. You have new rims... you don't want to risk scratching them. Also... a professional will install the valve stem and put a sealant between the tire and the rim, both are things that you need the pro to do.
It's not expensive... whenever I get new tires it's normally around $30 to have 2 done no matter where I go. Even walmart can do it for you... but I would stick to a place that has the equipment to fit the tire to the 18" rim properly without scratching them, call around and ask places if they have the equipment necessary to fit low profile tires to large rims.

Yeah so long the tyres are on the rims already and are balanced (you need to somehow make sure they are). Otherwise you need an air compressor, a hydraulic tire mounting machine, and a dynamic wheel balancer...

i am assuming that the tyres are already mounted on the rims. did you make sure before you bought these that they will fit on your car? if yes, then its no different than changing a flat tire. if you need further info, drop me a line.

Well, i don't know if u CAN do it or not, but it wouldn't be a smart idea anyway even if u knew how to do it
