I'm digging the R888's in the rear (pun intended). This thing launches so hard. Stock tires in the front. The R888's are slightly larger than the stock rears at 315 30 20 vs stock 305. I have always heard that mismatched tire size ratios can cause issues. Although didn't think it would happen with a very slight mismatch.

A couple days ago the car started running rough and then presented these errors and went into limp. I shut the car off and on and codes were gone. Car drove fine. Went to the dealer and while the current memory had no codes they were in long term memory so dealer cleared them.

Curious if you guys with rear R888's or diff sized tires than stock in either front or rear have triggered these errors.

Cheers.

 

R888 ran fine for me with stock size Michelins on front..I just took them off..had them on since spring..what a treat to get back on the std Michelins...much more quiet and smooth

 

Had the R888’s in that size, but 19” F & R in the 997.2 TTS with no issue. On my 991.1 TTS, I run MPSS 4’s in stock size in the R and 255 in the F with no issues.

No issues with the tires! Ran a 9.71 with them a few yrs back and still run them today.. No faults at all!.

No issues when I temporarily ran R888s in the rear with stock sized Michelins in the front

 

Sometimes that error can happen randomly. I've seen it at many levels of power and with different set ups. Cycle ignition and it goes away never to come back usually.
