Fitment Question Asap please
Wondering if 18x9 +33 235/45 fit onto stock suspension with a 1.4 inch drop? Im aware of the poke but concerned about rubbing.

You do not want a 235/45/18, it is WAAAY to tall. 225/40, 235/40, or 245/35 are your options. |
If you're not worried about the poke, then do it and then get spacers if it touches the spring perch

3 wheels have slight curb nicks. |

Also, 225/45 is too tall. Even a 235/40 is too tall at 3.3% larger than OEM diameter, but it will work. It is outside the 3% plus or minus the OEm diameter, that is the general rule of thumb for going up or down in tire size. A 235/45/18 is 6.9% larger or 26.3" tall!!! 215/45/17 is 24.6" diameter (OEM tire) 225/40/18 is 25.1" diameter 235/40/18 is 25.4" diameter 245/35/18 is 24.8" diameter |

Not to say that Leonardo isn't great; he's a great resource! Just like this - https://www.ft86motorsports.com/wheelitfit/ |

I have ran all these tire on 7 different wheel combinations. I was on springs, then coils too. 215/45/17 225/45/17 245/40/17 215/40/18 225/40/18 245/35/18 Anyway, the math is very calming for my brain. Thanks again! Edit: after 4 staggered setups. I am 100% sold on SQUARE being the BEST! |

Or should I run 225/40. Sorry I'm a tire noob lmao. Stretch lowkey scares me because the roads here are shitty |

Just keep in mind that since these tires are a little bigger than stock diameter, your speedo should be a little off with 235/40, but it's really no big deal for a DD and you'll gain about 1/4" of ground clearance which is VERY useful. The main thing is that the 18X8.5 +35mm is probably the best fit on stock struts, so you're on a good path... If the speedo is an issue for you, just go with 245/35/18 since it's the closest to stock diameter, as you can see on previous posts. As a bonus, with your 1.4" drop and these bigger tires, there will be no more fender gap on your car!! :happyanim: |

So maybe the ECU learned and compensate or it's just good/bad luck...:iono: Either way, that's my point when saying it doesn't really matter and the improved ground clearance makes it well worth it IMO. About the TPMS, I have those on my wheels and I think they can be installed on any wheels, but other members might give us more info about that. |

I also heard the stock ecu reads higher than what you're actually doing but idk haha. My speedo is digital so idk if i might be able to tell or not |
The speedo does not compensate or correct it's self. (how could it? it does not know the car's actual speed!)
