Alloy / Wheel size

Hi,

I've got an M635, And I'm looking to purchase some alloys and found some from a '97 Seven series could someone tell me if they can be fitted to a E24? they are 245/55R16 5 Stud. Can they just be swapped does anyone know ?

Thanks

Tim

Sorry but I no idea when it comes to tyre size, but all four are the same I believe as above. What he said exactly 245/55R16 100W

If they are 8 x 16 will they rub ? or just when on full lock on front ?

One of the original tyre sizes was 240/45 R415, so you have an increase in width and aspect ratio.

8x16 should be fine (many cars are on 8x17), especially at rear, but your tyre size would then have to be as near as possible to the original metric proportions. This is partly because you do not want to affect speedo readings too greatly.

In terms of full lock at front, it sounds as though you might be slightly hampered by the current tyre size there.

Hi

Thanks for your posts, Give me something to think about !

The wheels will more than likely fit, but the tyres will need to be changed as they are just too big. I run 16x7 wheels with 225/50/zr16 tyres. To be honest the sixes with the larger metrics are if anything over tyred and the cars handle better with a thinner tyre. I personally think my six handles better with the 225 width tyres then with the 235/45/zr17 that i had on before although these handled 50% better then the previous metric rubbish. If you wanted to run a 245 width tyre you would probable have to go down to an aspect ratio of 45. IE 245/45/ZR16.

Out of interest what 7 series model have the tyres come from. Is it a late e32 or the newer model as if its a newer model i am not sure if these wheels are the same offset.

I'll stick my question in here rather than starting a new thread, since its relevent.

My 635 is an 1981, and is therefore pre-TRX. It still has the original 14" BBS wheels with period rubber. I've just bought (ebay) a set of 16" BBS crossspokes from an M635, but they are rims only.

I'm going to go for 225/50 for the rubber, but what do you recon about the finish of the Rims? They are going to be referbished, but should I go for standard powdercoat or polished?.

Its true that I don't know what they were on originally, but they came from a guy breaking a knakered M635 (bought his steering wheel as well to replace my 'Bus' wheel).  Here is a picture to see if that sheds any light. Currently got two wearing 205/55 and two with 225/50.

I'm gussing they could be after market add ons, as they have BBS centres rather than BMW ones.

Should suit me fine though, since they are the same pattern as my current 14" wheels, and recently came off a 6 so should fit fine.

Longer than standard bolts. Why is nothing easy?

Thanks for the help guys.

Heh,

I expected Rot, bad fuel consumtion, big service bills, difficulty in getting parts, many many hours of cleaning... but "longer than standard bolts"!!! thats just taking the p***!

Can't say I'm suprised though!
