Tire help and questions
I'm looking to change the rear tires to a "stickier" compound. I'd like to get out of the dig a little better. I'm looking into "street slicks". Here is what I've found:
Nitto NT05R- I've read a few others on the forum using these. They might be the regular NT05's where there is no load or size problems (my questions are on the NT05R's): The 20" size is a 315 (too big for the stock wheel). I love the OEM 343's so if I went aftermarket to a 19" wheel the load rating is 1,477lbs for a 305/35. We have a heavy car! The oem Michelin PSS have a load rating of 1,819lbs. I'm thinking playing it safe and staying around here. Therefore, it looks like the NT05R's are a no go for me (load rating is too low on the 19's and 20's are too big for the rim) ???? Thoughts? Nitto NT555R- 305/35/20 load rating 1,984lbs (exceeds the oem PSS's). No 19" tire available for the NT555R. Anyone run into trouble running a 35 in the back? Any rubbing? Did I mention my car is lowered? Dinan coil overs. Mickey Thompson ET Street Radial- 305/35/20. I can't seem to find any information on the load ratings... Also, is this more of a street tire than a street legal drag radial? And again, same question on rubbing with a 35. Any other suggestions? I've looked at a few others: Toyo R888R etc and the size is not what I'm looking for. I'd like to put a 305 on. Ideas? Thoughts? Feedback? Thanks! |

Let me rephrase:
Is anyone running a 35 aspect ratio (height) tire in the rear with stock 20" wheels? If so, any rubbing or fitment issues? |

I bought a set of the standard stock 19s and now run a MT 305/35 19. Less issues with part throttle acceleration but I can tell it's not quite right. Putting the stock wheels/tires back on and instantly the problem goes away. Btw, the MT DRs are some seriously sticky tires that will still let you drive to/from the track. What I suspect is that there is a very close tolerance for speed differences between front and rear wheels. BMW seems to have not accounted for larger rear wheels that would then turn "slower" than the front wheels. I'm currently thinking about going one size up when my PS2s wear out in another 5k miles. I'm thinking I'll go with 305/30 20 and 275/35 20 up front. Morale of the story, make sure your wheels/tires are as close to the same ratio as the stock setup or you could have problems. -just my .02¢ |
