Re: how big of tires have you guys fit without lifting
I have a 79K5 now with 4" of lift. I'm pretty sure I could fit 38s on there before it hit the cab. The only way I could have less fender is if I didn't have any.
If you're cheap, you can usually find used 4" lifts for $150 including steering arm. At least I did for my truck and that's what I'll probably sell my other one for.
I think the biggest you can fit with no lift and a lot of hacking is 36s on 15x8s... and then it'll still come close to the cab.
