Anyone able to clear 275's all the way around on 67-72?

[Freeman69]

Just picked up a 69 c10 SWB and have been shopping wheels and tires until they all look the same, here is my question,

I know that 255/40r18 is a popular front size and 275/40r18 for the rear but has anyone ever ran a 275/40r18 front and rear? I'm looking at an american racing 18x9 set of wheels all the way around. Has anyone ever been successful or unsuccessful in this matter?

They don't make the wheels i want in staggered sizing and i don't know how it would look running a skinnier front tire on the same size rims.

As for suspension i am going Ridetech street grip and motor will be a 5.3 LM7 on boost with a 4l80e. Body is all original patina and rust nuts.

Appreciate the information,

Hayden
