Good question on tires size geezer,
I was wondering that too.
I don't know what tire size i have, I bought the C30 dually in Colorado from my dad's neighbor the day before I flew back to California, so I'll have to ask him to go outside and look at the tires for me.
I'm trying to figure out what all I'll need to do to drive the dually, hopefully towing a K10 shortbed, back to California in the spring.
What size tires do you have THI?
Obviously dually tires can only be so wide before they hit each other, does anyone know how big or tall a dually tire can be with stock rims?
Another question, how many rpm's is comfortable for a stock 454 to run all day on the highway? Carbureted original 1979 type 454.
Thanks
