PICS WANTED - 3/4T w/33's

[Paul72]

I would like to put 33x12.50's on the K/20 (stock ride height) and would like to see pics of this combo. Also any rubbing/interference problems? The wheels are 16x8 (don't flame me for this - I know 10" wheels would be better).

My gut feel is that this would be no problem, but want to double check before I spend the $$

Thanks,

Paul

Looks great...my roommate used to run them on his '72 and here they are on my '68 with the stock 8.25x16.5 rims. Plenty of clearance. The rears are 33x12.5x16.5 and the fronts are 31x10.5x16.5's but the 33's will fit on the front and I will change them once the 31's wear out.

Here are pics of my '67 with 33's on a 16.5 rim before and after I bought it.

Thanks for the pics! Forgot to mention mine is a 4x4.

If you have any interference at all, it will be at the lower front corner of the fender (in front of the tires) - typically only with the wheel turned out, off-road, with the suspension compressed at that corner. If you don't mind a little hacksaw trimming, it's easily fixed and barely noticable. Chances are with 8" rims instead of 10", you won't have any problems at all. I'd say go for it - that's a great size for a K20, you won't regret it.

8" rims are always better than 10" rims when using 12.50 radials. Better bead seating; better sidewall buldge; better road manners since, with an 8" rim, the sidewall won't so easily flex inside the bead plane under hard cornering. About the only instance 10" rims would be better would be flotation for sand travel.

I've used 12.50 tires for two decades now and have always used 8" to 8.5" rims.

As for fender clearance with 33s on stock K20 springs, the main area of concern is the bottom of the front fenders next to the bumper. The front fender "cup", as it's often called here. A little trimming there solves any rubbing issues for most wheelers. Maybe not for extreme wheelers, but they run lift springs anyway.

I have 8" rims with 33 12.50 16's on mine, but went with a 4" lift. When turning they were too close for my liking. I don't consider myself to be an extreme wheeler by a long shot. I've got a bolt head sticking out behind the tire on the fender well and it was rubbed clean and shiny without even going wheelin. The front also had rub marks. But it doesn't take much of a bump for your tires to rub when you're turning. I guess it just depends on your driving habits and preferances. I also like the stance a bit more with the lift.

here is a pic of mine--- on the left is with bald 31/10.5s on 7 inch wide wheels, the right is 33/12.5s on the same 7 inch rims

The white one has 33/75x16.5 0n 9.75 rims.The springs are very negative arched.
The 2-tone has 285/75x16s on 8 rims.It has an added leaf and they are straight.The 33s are a good bit shorter than the 285s.They both rub a bit,fit good enough for street.
