Guys, my old clark has 16.9 x 30 tires now. My buddy found a pair of 18.4 x 30 skidder tires. How much diffrence is there in the rolling circumfrence of these sizes? Would it be a no-no to have diffrent sizes on the bak then the front?
Thank you
I'm not sure how the 4x4 works on skidders, but on most vehicles with 4x4 the front and rear rolling circumference should be the same.
As long as they're all the same size, they should work.
Don't miss match sizes
8 inches taller aint gona work.............
It will if there arent fenders in the way
Profile of the tire will make a lot of difference. The main thing is circumference, if that is the same they will work. It has to be exact.
My old 1977 cat 518 runs 18.4 x 34 as standard. I ran 2 16.9 x 34's on the back and had no problem.
Thanks guys good advice as always
The Clark has no spins in both axles and no seperation of the front and rear drivelines. Odd sizes will give you driveline wrap up and you will either be pushing two tires or dragging two tires, extra load on the machine and doesn't help tire wear either. Keep the sizes equal front to rear.
i think the width of the tires is the only diff. the height is close with those two sizes..??

A firestone 16.9-30 is 59.2" tall with a rolling circumference of 178"
An offbrand 18.4-30 is 60.9" tall with a rolling circumference of 196.5"
So one of the tires is going to have to travel/slip almost 20" more for every revolution. That is quite a bit.
only thing I can think of would be to lower the air pressure in the taller tires, essentially reducing the rolling circumference. I'm not sure that would be a good idea, though.
Do not run different size tires or you will be paying dearly in days to come.

Can you tell me were this info was found? I tried to find it and could not.
Thanks for all the replys.
I'll be putting on the 16.9 x 30. So they all will match.
I got it from the firestone ag website, and some other website that listed a 18.4-30 tire.
there both 30 s i would run them. no different than having well worn rears and putting on new fronts. who can afford all new tires nowadays? mine are over 2000.00 each. ill be runnin used tires the rest of my life.
