are tyres for e36 m3's very hard to install?

[m3f_porschetec_4d0a5fb1fc]

i just had my mich PS-2's installed by a local tyre shop. cost me $140 for 4 supplied tyres, balanced and fitted. i nearly passed out. apparently the reason for the charge is that the m3 rim is a very difficult wheel to work with. the rim needs to be faced down and the tyre removed and installed in the reverse of conventional rims. is this true?

by the way........i have 2 SO-3's for sale if anyone is interested. 225/45/17 @ 5mm tread depth. $60 the pair

Never heard of that before. I have always just had them installed like any other wheel/tire combo.

Maybe they do that to protect the front lip from scratches on the mounting machine

It is Absolutely untrue that they are any different. More than likely they see a BMW and think deep pockets, and that the owner is alien to the ways of tires. I mount all of my own tires at a friend's shop and I mounted up some 235 45 17 pirellis over the weekend. The rim was face up. It helps to use a pry bar rather than a tire lever to seat 17 inch tires, but it is not at all hard. They take maybe 60 psi to seat which is not much. For my own investigation of what will fit i first mounted them on the front wheels, then on the back, to see if i got any rubbing up front. Low pro tires of that diameter are hard to mount in general the M is no more difficult. BTW town fair tire will do it in CT for under 50 dollars. Land Rovers are difficult because trhe rim has a double lip design so that the tire bead sits in a valley, this alloys the tires to be aired down without fear of breaking the bead.

In addition if you put the wheel face down, it will get scratches from the jaws on the machine, if it will even sit on there at all. The jaws are roughly 2 inches tall so that would require at least a 2 inch outer lip to grab onto. When dismounting, its true that the outter lip should face in to prevent dammage, but that is no harder than simply putting the wheel on the other way. Nearly all machines have an adjustable tool rest that will not even graze the outer lip of the wheel if the operator takes the time to adjust it when mounting.

i know what ur talkin about.. i dont know what it is.. i went to a place and they wanted 80$ a tire :rofl2: .. i was like.. fug that.. went down the street and paid 80$ for all 4.. both places were very well known around my parts and had won awards.. but the one that mounted them for me races E36's :agree:

I have personally mounted and balanced more M3 rims can I care to say. The M rims are some of the biggest PITA rims that BMW has, due to the lip. The worst being the rear rims on the m-coupe's. It's taken up to five techs before to mount one tire on one rim.



I am glad I don't have to mess with that **** anymore. Although, once I need new tires I'll probably head back to BMW and ask them if I can use their tire machine again. And yes, I mounted and balanced my own rim's and tires.



I have cussed out a ton of M rims too when I worked at BMW. Kind of funny. Mother****ing tires get your ass on the god damn rim! AHHHHH!

I am used to truck wheels and tires, so i thought they were not too bad of a lip to deal with, so long as you used a pry bay. But charging more is ridiculous in my opinion. At landrover we used to inflate the tires to about 80 psi and chain the wheel to a lift post, then hit the tire with a mallet in order to seat the bead talk about cussing.. especially with michelins.

[m3f_Sirius_880bd69485]

You have to take into account the sidewall of the tire too when you mount the tires. Truck tires have nice big sidewalls, which flex easily. Low profile tires are a pain because the sidewall doesn't give much when you need it to. Run flat tires are the worst, as their sidewalls are like steel. :banghead:

i too have installed quite a few tyres. (porsche only). as i didn't have the time to do it myself i thought i'd take them to our local tyre shop. so i was pretty shocked to hear how much they charged per rim. it didn't help that the rear tyres looked like slicks. so i said....f*** it. let them do. but i was certain i could smell some BS. but then i've never mounted a tyre on an m3 wheel. so i was none the wiser. still never heard of reverse mounting tyres. :nixweiss:

[m3f_Sirius_880bd69485]

Reverse mouting is when you put the tire on from the backside of the rim instead of the front.



This helps on some rims that have especially large front lips, as the tire will slide onto the rim and seat easier than doing it from the front.

[m3f_porschetec_4d0a5fb1fc]

yeah thats whats they told me. they said only bmw does that style of mounting.

[m3f_Edgy_592e912c16]

My mechanic says the same things Sirius says. He's also mentioned some kind of tool that many shops don't have to make the job easier, never explored it further since I've never had him do any tire stuff for me.

Funny you should say that badgtho. Are you talking about the one on High Ridge Road? I like those guys a lot, and went to them for many years when I was up there. Unfortunately when I had my special order Toyo's put on there back in 2002-3, they TOTALLY botched the balancing. I had to get it redone. In their defense, they refunded me the amount I had to pay.

You can reverse mount any tire you want. Just flip the rim over. :???:
