1977 C20 Widest Wheels and Biggest Tires

[Tubba]

What's up guys I'm new to the forum. My grandpa passed and my grandma gave me his truck. It's a 1977 C20. Right now it has old cracked aged 31x10.50-16.5's I was just going to buy new tires but nobody makes 16.5 tires anymore so I have to buy a new wheel and tire setup before I can start driving it. My main problem is that I have to order everything so I wanted to know what is the widest wheel/tire combo I can run? I would love to have a deep dish setup but I don't want to order anything that will end up not fitting right. Truck is stock height. Thanks in advanced (I kinda like that summit racing offers Bart wheels 15x10 and 15x12 but they are 3.5 back spacing and don't know if they would work out)

Depends on the look you are going for. You want **** truck look or tough truck look?

I've actually always really liked the wheels you have right now, the black centers just make them look "right".

I have a 15x10 with 3.5" or 4" backspace and they clear the caliper fine. Then you should be able to SQUEEZE a 32x11.50x15 under there.
