I'm not seeing any smoke from those tires.

Hi Guys, I have 275/60/15 on the rear and 235/60/15 on the front.
The rear looks too high for me given I put new rear suspension on it just sits high.
I know I can lower it but its the tyre size that looks a little to big.
I believe but not entirely sure as its been a long time but think its 8.5 on the rear, all on BF Goodrich.

Ive read many posts but still can't settle on an exact size, 255/60 255/50 ?
Any help and a pic or too of the rear tyre would be amazing, thanks again for your help, I think I am on the last 6 months of getting it roadworthy
I hope, famous last words right....

I discussed those rear tire sizes in the first post of this topic, with the chart I made. I would agree that 275/60/15's would be rather tall, and depending on the wheel backspacing, could have issues with rubbing. Some people use that size without issues. I like 255/60/15's, they're closer to stock height and will look plenty wide enough with 8.5" or wider wheels.

235/60/15's on the front (although some members use this size) is nearly an inch taller than stock diameter. It wouldn't be my personal choice. Re-read the first few pages of the topic as several differing viewpoints were shared, as well as driveability considerations.

Thank buddy, I guess I overlooked some of that text!
I have BF's on at the mo but thinking of changing the tyre, they are probably square now anyway.
I like the sound of losing the height look, i had it on the last charger but that was semi set up for drag so tyre height was ok.
Thanks again.

You're welcome! If I was using 275's, I'd probably move down to a 50 aspect ratio to keep the diameter closer to stock, but 275/60/15's were and are still pretty common on the rears of Chargers, and unless your wheels are 10" or wider, shouldn't present issues with rubbing. I'm not a fan of front tires having a taller diameter than stock, though--regardless of whether it fits or not.  Tongue

I will have to do the math later to see how my combo checks out, but I have 265/50R15 front and 295/50R15 rear, all BF Goodrich on Centerlines.

Pretty sure they are 8" wheels all the way around.

The fronts do not rub but have 1.08" torsion bars (aftermarket) (the air in the tires is the only cushion  )and the rear Centerlines have the 4 7/8" offset to tuck in more.

Had those tires on the car since 1986 and they still look like new but I'll be getting new tires (and probably wheels) after the body work is done since I would barely trust them for a trip around the block now.

If you get out the plasma cutter, you can fit a whole lot more in there.

front 225/45/18
rear  335/30/18
