Best tires size for a set of 15'' Fuchs 9J and 11J
Hi guys, I have a wide body project, and looking for perfect matching tires for a set of 9J & 11J Fuchs.
I saw in many posts, for front, recommended size is 225/50, or even 215/55. For me, this sound difficult to fit on 9j and, as I saw also on Michelin webpage for example, none of those sizes are recommended for 9J. What tires do you guys have on such set of Fuchs? thanks in advance for your advice, Daniel |

Pretty tough finding 1988 tire sizes in 2018. What look are you after? The RSR look and the 930 look are a little different. I've been running those sized wheels on widebodies for decades and have a set of 345/35-15 Pirelli if interested in that look. They are a bit wide for an 11" rim but were commonly used back in the day. Shoot me an email if interested.

The michelin tb15 215’s work on the 9s and the 295’s on the 11’s. I use the 215’s on 8’s and also used them on 9’s.

Pirelli P7 Corsa Classic, or Michelin TB5 or Michelin TB15 The TB15 has a poor selection of sizes the 18/60 which is nominally equivalent to a 215/55 is spec'e for a 6 to 7.5" wheel, it's a real stretch to put it on a 9 the best match here is a 23/62(270/45) front and either a 26/61(295/40) or 29/61(335/35) rear. The TB5 range is similarly handicapped the 18/60(225/50) is specced for a 6 to 8" wheel, again a big stretch to fit on a 9 best match here is 23/62(270/45) front and 29/61(335/35) rear. Pirelli P7 Corsa Classic has better matches the 225/595(235/45) front and 305/35(305/35) rear would be best choice here

The 215 is wider than you think. It still bulges over a 8" and is near flush on a 9". The 270 is a taller tire at around 25.7" vs the 215/295/335 which are all around 24" tall. To me, the 335 is too wide for the 11" rims. I use the 335 on 13" wide rims. The photo is a tb15 295 on a 11x15"

Additionally, 215 front w/ 295 or bigger rear is a mismatch in width and grip

For 11j, I think 345/35 are too wide. I would prefer 285 or 295/40 for rear. See few pics below. ![]() ![]() ![]() |

If you are looking for period correct the '73 2.8RSR w/ 9 & 11 x15 ran 230/600 & 260/600
the 3.0RS on 8 & 9 ran 215/60 & 235/60

I'm still not sure if I can use 215/55. Waiting the picture, or other confirmation... thanks all for the involvement and help. Daniel |

the 18/60 is spec'd for 6 to 8" wheel, and is still a stretch on a 9, but still better than the stretch for 215 onto a 9. I personally wouldn't go more than .5" over spec. Can Hoosiers be used they have 245/40 & 275/35 x15 which would be perfect for track use, not so much for road use.

You'd need to ask Michelin about their tire specs.
Here are 2 shots of the tb215 on 9's The last shot is a 215 on 8's. Tread width is 7.750", side wall width is 9.875". ![]() ![]() ![]()

![]() Thanks for the info. Probably I'll go for this combo. What do you know about Pirelli Cinturato P7 Classic? Did you saw or use this type? I'm interested to see if these are also good for a track day car. thanks |

Good to see a refreshed conversation about this. Seems like the ever-shrinking market of 15" and wide tires is always a hot topic. I would like to bump this up, if you don't mind.
I would also like to add the question to the topic of how we feel about any of the discussed tires for normal road use. I've always liked the TB5/TB15's and seem like they would be decent, but always wondered about the compound and how long they would actually last on something driven regularly. |

TB15’s barely made it 5,000 miles (no track miles). Seems acceptable\ expected for this type of tire.
Current (Oct 2018) problem is replacing them, appears TB15 26\61 are discontinued and only similar option is the TB5(R) 26\61. Anyone know different? Tim |

There is the Hankook Ventus H101 in 265/50-15.
Unfortunately, no matching sizes for a front. It is 10.4" wide, so it will work with a 10-11" rear wheel. |
