tire size questions

While on the subject, my 33" KOA's have a few miles to go before replacing.
Oh, btw, '78 K10 bone stock.
I believe I have 15 x 11" wheels, and thought I might try 35" on the next go round.
Any thoughts on if the 35" being wider and the wheel being the same might bow out the sidewalls?
I did a clearance test and I don't think anything will rub.
Thanks in advance for any guidance!!!

35" wont fit on a bone stock K10 without tearing into the rear fender. I would imagine these have some offset on them and if that is the case 35's will most likely hit the bottom of the front fenders
what is the width of the 33's on there now? You can technically get the same width on the 35's, but that extra 1" of circumference is the issue.

With her current stance I can't see how that would happen. But I just don't know.
Oh, so not the top of the fender, but the skirt nearest the wheels?

Yes, It typically hits at the rear of the fender opening.

I RAN 33.50"s on my K10 in the past and they fit well.

So I guess it happens while suspension is compressed, correct?
What if you're only on street?

yes but it wont take much compression, driving out of a sloped driveway could do it.
If it ever bites that part it will pretty much ruin a fender, If you feel like it is a risk you can take, that would be up to you.

Unless you plan on lifting it two more inches, stick with the 33"S

33" tires on my '77 K20 with stock suspension. No way 35" would fit without a lift.
