Meaty tire setup on 20 possible ?
Meaty tire setup on 20, specs 20x9.5 et22 & 20x11 et40 possible?
Has anyone run 275/30/20 on a 9.5 & 305/30/20 on a 11. Have pics of how it looks? I know 265/30 & 295/30 is the preferred sizing on a 9.5 & 11. but I would like a tad bit more meat if possible. 295 looks good on a 10.5 but a little stretched on a 11. Would running a 275/30 & 305/30 Mercedes spec ps4 help? Since the tire runs a bit more narrow than a reg ps4. |

275/30/20 on a ET22 will work.
305/30/20 on an ET40 will likely rub, you need ET44 to clear a 305. A 10mm spacer would fix that. This assumes stock suspension height.. |

Looking into MPhas springs.
Et44 does seem to be the sweet spot. Was hoping there might be a chance wit et40 Not sure about the 10mm spacer. That would push the rim/lip further out, making the et40 to et30. |

305/30 on 20x11 et40 shouldn't rub at all. I now have 19x12 et45 with 325/30/19 lowered, no rub at all! Before I had 20x11.5 er47 325/25/20 before lowered and no rub either.

305/30/20 will rub without question on a 20x11 et40. I've tried so myself with MPSS. If you have a thinner tire, perhaps from Toyo, you may be able to get away with it if your camber is around -2.3 or so but I rubbed with a camber of -2.2 on a Michelin PSS N0 sadly.

Do anti-spacers exist? I think that would work. |

After some more research.
The most popular sizing for 20x9.5 et23 & 20x11 et40. is 265/30/20 & 295/30/20 Doesnt seem like i can go up in size, except for the front too a 275-30-20 and keep the rear at 295-30-20 Fitting a 305/30 rear et40 seems possible, but a case by case bases. Depending on a combo of things: height, offset, -camber and tire brand. The best compromise for semi-meaty setup for me would be to run 275-30-20 & 295-30-20 The sidewall slant/stretch should be somewhat even front and back. I get that little extra pothole protection in the front, over a 265/30. |

275 on 9.5 is going to be a bit less stretched than 295 on 11. This is benchmarking on the 275x9 and 295x10 that a lot of zcp owners run.
This is probably a good thing because if you're most concerned about potholes, the front wheels will take a harder hit than the rears. Either way I don't think you'll be disappointed in the performance of the 295 MP4S'. They hook WAY better than 285 PSS's |

325 on 11.5 is fat fat on the side well compared to 305 on 11. I don't have 20 anymore but today I have 325/30/19 on 12 et45, it doesn't have rub problem either |

Same reason why a 305/25/20 fits on 20x11 et 40 with -2.8 camber.. thinner profile / shorter tire / camber Last edited by JamesGames; 02-24-2019 at 10:14 AM.. |

Hey everyone.. Was reading through the thread and don't think I saw anything about a 265/35/20 working on a 9 in rim +20ET. Does anyone know if I'd run into issues? I haven't lowered my M4 or anything yet as I was waiting to get my wheels.

That's a very tall tire for the front.

Sheesh.. I was worried about that. Will I have any rubbing issues at stock height or when I install my coil overs? I was on the site where I bought my rims and was trying to following the tire recommendations. They had 255/35/20 though and I wanted something a bit wider so i went 265/35/20. Smh..

For a meaty look, you can do 20x9.5 ET18 front and 20x11 ET42 rear, perfectly flushed (assuming you're lowered / natural camber). 275/30/20 front and 305/30/20 rear will be perfect, no rub. Below is 20x9.5 ET18 front with MP4S 275/30/20 to give you an idea. Rear is 295/30/20 on 20x11 ET38.

At least I didn't have the tires mounted yet otherwise I'd be out some $$. Still got time to exchange them. Back to the drawing board. Thanks everyone for the feedback

I’m going to run 275/30/20 like your pic. FYI, for anyone looking to run 20x9.5 et:23 & 275/30/20 on MPhas like me. There might be a inner tire clearance issue with the front perch. A 3mm or 5mm spacer might be needed to clear. I’ll update when I get MPhas. Last edited by M3SemiSlow; 03-06-2019 at 10:02 PM.. |
