Will a 19x8 rim support a 275mm wide tire?

Current tires are 245/50R19 and I wanna step up to a 275/30R19

TIA

9.6" wide vs 10.8" wide... that's 1.2" more

Quite the leap...

all cosmetic though. I put myself in a jamb with my firebird.

I bought 5th gen Camaro rims with OEM tires. that combo is 29+ inches OD while stock is a hair above 26. They wont fit in the wheel well.

I came across a good set of take offs from a Porsche, they are 245/35r19 fronts and 275/30r19 rear

the fronts are a perfect match, the rears well.....

theres so much wrong with this wheel tire debacle I got myself in I just want to get them on the car already. Luckily I'm into everything at a point where if and when I sell I should still break even.

yes. you have a problem... and I am not sure exactly if it can be fixed!!! Lemme think on it...

But I suspect you have run out of space in the wheel wells, and short of a tire with a 20 aspect ratio, you will make them fit.

I just don't think you will fit that much rim in that little fender...

I went with the crash course in rims and tires and learned a lot in the last few weeks.

It all boils down to the O.D. of the wheel and tire combo. Keeping the o.d. to as close as the oem is key.

The oem set up on my firebird had me at 26 inches. the oem 5th gen camaro is at 29 inches. My firebird wheel well opening is 29", not gonna happen!
I ended up finding a set of LOW profile take off tires and bought them ( god bless CL!) for $60.

they are 245/35 and 275/30 and will bring my wheel and tire combo to 25". now the question will be how will it ride.

On the line of the 275mm width on an 8 inch rim, will it fit... yes. Is it correct, no.

At this point I just wanna see the rims on the car! If I like them I will buy the correct tires next summer and go from there.

The first pothole will equate to the first bent rim. Sorry...

It will ride firmer, but should handle ok.

The reason why that overall number is so important is because of the ABS and traction control... if they are not fed the right info, they will freak out. And yes, there is a fudge factor for tire wear.

Don't be sorry for speaking the truth!
Your absolutely right. I'll most likely be pussy footing it around town so bad I'll get sick of them and end up selling them.

Or I'll like how they look and dig further into a tire that has a higher profile and will be more forgiving.

If 26" is the factory OD I'm thinking 27" is the max without throwing to much off. But I'll burn that bridge when I get to it!
