74 biggest tires

[jkling1974]

Anyone know if a 275/70 15 will fit on back of my 74 challenger ?

I’ve Always used 275/60 15 on all my mopars but would like a taller tire if possible.

I plan to buy a Mickey Thompson if someone tells me they’ll fit lol

Not sure they make a 275/70/15?

Tirerack.com doesn't list anything in that size. I think you're right.

 

[jkling1974]

Mildly Thompson shows them but I didn’t get them I got 60s

 

[moparleo]

What are you trying to accomplish ?
I was in the tire business for over 30 years and never saw a street tire in that size. I have seen 275/70-17 and 18" truck/off road tires, but no passenger car street tires.

 

[jkling1974]

I already said I got the 275/60 15 I always get . I wanted a taller side wall tire. that's all. I thought I was clear on that.

Mickey Thompson Section Width: 11.10 in. Tread Width: 9.29 in Tire Diameter:28.19 in. . Listed on summit racing.
You early said: "I’ve Always used 275/60 15 on all my mopars". you don't have an older set to try on the challenger? How much room is there to the springs. A tire 275/70/15 would be about
31X10.50R15
Diameter : 31.0"
Width : 10.5"
Wheel : 15" x 7-9"
Sidewall : 8.0"
Circum. : 97.3"
Revs/Mile : 651
275-70R15
There are no Tires Available
in the Calculated Size

 

[jkling1974]

I do , and that what's on the car now , I wanted bigger if possible so I was asking folks if there was bigger tire that can fit. the quick answer was no. there are people who make 275/70 /15 tire but yes its a truck tire. I was just wondering what was biggest tire. I wanted a taller profile that's all. answer is nope lol

Truck tire correct.
Diameter : 31.0"
Width : 10.5"
Wheel : 15" It on my Dodge Dakota all the way around but that's no help.
