RE: TRX BMW tire alternatives for 533i

["Karl Zemlin" <zemlin@xxxxxxxx>]

When I bought my '85 353i it was wearing 220/55 TRX's.  No problems.

It now wears 225/50-16's.  No problem there either.

| Phil,
| 
| Your 1999 post read "Tire size was the same as 535i:  200/60VR390,  220
| is a common replacement and cheaper since it also fits Mustang 5.0's I
| believe."
| 
|  Though I bought four 200/60VR390's for my 533i in 1999, tire rack and
| others are currently reporting no inventory and no due date on when
| Michelin will do their next production run.  That got me looking at
| alternatives -- 180/65HR390 and 220/55VR390.
| 
| I am reluctant to remove 10% traction of the 180's while I think the
| additional 10% traction of the 220's would be ok.  The diameter of the
| 220/55VR390 is within  0.7% of my current tires and the extra 0.8" width
| of the 220's seems minimal but is the focus of this inquiry.
| 
| I understand my wheels are 165mm by 390mm.  Do 220's properly fit the
| 165mm dimension of the wheel?  The 220mm is at the sidewall and some
| taper exists to the width at the wheel mounting area.  I am asking how
| critical is the molded taper.
| 
| Since I am looking to use the same wheels, offset is not a direct issue
| but have folks found that the additional 0.8" tire width works in the
| wheel wells.
| 
| Thanks in advance for your help.
|
