275/40/18 Indy 500 won't bead all the way I was really excited to get my Firestone Indy 500's mounted. No matter how hard we tried, one of the 275 rears wouldn't totally pop onto the bead. I holds air but it's not touching the bead for about 2-3 inches on the wheels circumference even at 50psi. This causes a distortion were the sidewall meets the tread. My buddy who's been mounting tires for 20 years has never seen this. Anybody else ever have this issue? The 245's popped right into place. The other 275 was a little difficult, but the one in question just isn't happening! I've probably had 5-6 different tires mounted on this wheel and never had any issue. It's at 53 psi right now. Gonna let it sit in the sun tomorrow an hope it snaps into place. |
Kinda wondering if the tire has a busted belt that will cause it to distort |
Return it and move on |
Break the bead back down and sprays mixture of dawn dish soap and water in the bead then hit it with the cheetah. There's no way it won't seat. |

I left it inflated to 53lb, and set where I knew it'd get sun all day (low 90's today). It was seated when I got home. It was lubed with some type of tire grease that was painted on with a brush. I did call Firestone, and they said there's no issue with these tires. They did say a 9" wheel was minimum for their 275. I believe the v wheel is a 8.5". Never has been an issue on the other 4-5 275's I've mounted to this wheel. |
Every now and then I see this issue. Just had a guy roll in the other day with a 5th gen Camaro on factory 21” rims and his new Toyo tire wasn’t fully seated and he complained of vibration issues. Surprised the shop that installed them didn’t notice the damn assembly wobbling all over the balancer. Usually it’s due to improper fitment (ie wide tire on too narrow of a rim), other times inadequate lube. Some brand of tires just don’t seat as easy as others. I always have to lube the shit out of Falken tires (that have any kind of stiff sidewall) or they won’t seat without some ungodly air pressure. Just break the bead and re-lube. If you just drove off with it unseated and waited for it to seat itself go have it rebalanced because it sure as hell isn’t balanced now. |
Lots of lube and 100+psi solved all of my tire issues Biggest problem is with some of the RComps and DR |
Lots of lube and persistence will solve most every fitment issue you come across. :jest: |
275 tire on what width wheel? Chances are because the tire is too large for the wheel you are mounting on. CHoose a Proper size tire for your wheel an avoid all of these silly mounting problems, along with the negative characteristics discussed in my link. |

9inch and no a 275 is not to big |
Why would you put a 275 on a stock rim? |

For better looks (subjective), for (perhaps) more straight line grip...all in exchange for a loose, squirrely feel mid-corner. Looks worse in my opinion. The tire bowls and yes loose. |

Everyone is a drama queen on the internet. |
And just like buttholes, we all have our own opinions. :drive: |
