TBone,

I just happened to have a set of R888's that I used for my recent drag strip fun last weekend. I put them on the rear in the 295/30/19 config on my stock M5 rims.

The tires just barely fit on the rims (almost too much width for the rim) and they tuck perfectly in the fender well with almost no room to spare.

I think they helped my 60' times, but I still need practice in heating them up to proper operating temperature. Their optimal operating temp is 200 degrees F according to a review I watched on these tires.

I wouldn't use them for anything other than autocross or the drag strip.

I drove 60 miles to the drag strip and 60 miles back home on them with no problems whatsoever. I also could not get a 1st->2nd or a 2nd->3rd gear scratch on the street with these so I know they have more grip when warmed up.

Hope this helps.

Regards,

Darren

Thanks guys!

Looks like the best strategy is to wait. If the 295s won't fit up front, I will need to wait for 265 or 255s.

Darren, did you get any wheel rub in the rears at the autocross?

NB, I await with eagar anticipation :) Cheers.

No rubbing when I used the stock M5 wheels on the rear. I did not try these tires on my front wheels.
