Recommended tires sizes for bored-out E38 M-Parallels?

[DrewZ]

Any Suggestions on Tire Size for E38 M Pars bored out for an E39? Does anyone have any experience with them? I have heard that they are difficult to balance.

As the original poster, I'm (sadly) still running 245/40/18 all around -- even on the 9.5" wide rear rims. I will probably pick up a pair of 18x8 front rims so that I can run a square setup and rotate front-to-back.

I meant to say I have replica m-pars not OEM. They are 18s staggered. Was wondering if anyone had experience riding on them

Bumping this up. I reinstalled my Style 42s with all-season tires as we transition into the cold months. My bored out M-Paras are listed for sale here:

I run 245/40/18 in the front and 275/35/18 rear on a 99 528iT. Standard M5 sizes.

The tourings have a lot more room in the back than the sedans do. A sedan with sport suspension may risk rubbing on dips

7 months late to the party, but as an owner of a sedan with sport suspension, and a 275/35-18 rear tire - this is not an untrue statement. It's generally just on the big whoops at speed, usually only when I have crap in the trunk or a full size adult in the passenger seat. I really need to stiffen up the rear and put in M5 liners.

FYI, did you know they make a spacer adapter (sells on ebay for $100 all four) that converts E38 bore to E39 while also giving you 15mm to stance yo sick ride?
