help with tire size
 

I have a 72 k20 with 4" rough country spring lift. debating on installing 33" or 35" tires. I will be mounting them on 10" wide x 16" diameter wheels
motor is stock 350.
basically a road princess.
wondering what others thoughts are on this combo
thanks

Re: help with tire size
 

K20 will have a minimum 4.10:1 gear ratio, so the 33"-35" tire size will actually make the truck much easier to tolerate at highway speeds, and the 350 will have enough torque to move it adequately.

looking for some info on the 33" vs 35"
guy at tire shop was a little negative on 35's
checking to see if anyone had negative experience with the 35 vs 33
ie.. rubbing or ride things

My '68 has a 2" lift with 285/75-16's (equal to 33's), no rubbing at all. Drives great.

1972 K20 around 5” lift in the rear and 4”+ a little in the front because of the dana 60 I swapped in, 315/75R16 (as similar as you will get with 16” wheels to 35’s) on 10” wheels. 350/SM465. Runs about 2600 RPM at 70 MPH. Doesn’t rub under normal driving conditions, and have only had it run once or twice off road fairly flexed out.
