Will 33x12.50's fit on a stock height 70 K20?

Came across a great deal on some 33x12.50's for my stock 16x8.25 steelies. Will they fit without any rubbing issues on my stock height 70 k20? Thanks in advance guys.

I have 35x12.5's on a stock 69 k20 and had to notch out the front fenders about ~2.5" due to rubbing when turning. I think offset has a lot to do with it. I know its not necessarily what you were looking for but hopefully it serves as a guide as more people post.

my 68 k20 has 33x12.5's and they fit fine when it was stock height. These tires are cheapo's though and are only 32" tall.

Thanks guys. Plan on doing a 2.5 inch lift eventually anyway so, if they don't fit I guess it will give me an excuse to lift it sooner

They'll fit so long as the offset isn't hugely negative.

67-72's benefit from this because of the larger rounded wheelwells.

Stock '71 K20 with flat/no arch front springs. Been running BFG all terrain 33's on 16.5 x 9.75 Kelsey Hayes steel wheels, no problem.

With 8.25s,no problem at all for sure. My front springs are weak and with 9.75s they "could" rub just a bit. But,wasn't an issue and did no damage to tire or fender. I did eventually change to 8.25 Vectors when I was trying to sell because I wanted to keep the wheels. Those never rubbed. Ended up selling another truck,keeping this one,and selling those wheels. Ya just never know!
