    Default Unimog Tires 20" rims. 12.5 r20

    Unimog Flu419. I want to upgrade my OE tires 12.5r20. Has anyone tried to put LMTV 20" tires on a Unimog? 395/85/r20?

    I haven’t heard of anyone trying. Based on the 406’s, I think they are unlikely to fit without a cab lift. I have seen pictures of a 406 with 395’s and that required a cab lift and step relocation. As I recall, the 395’s are 46” tall. There is a member on here with 365/80 which are 42”tall. It is said to avoid 365/85 as they are heavier and prefer a narrower rim.

    An 11R20 will mount on the wheel. They are 42s and rub a good bit. 14.5R20s will as well.

    Ok, another tire question. I spoke to Idaho Motorpool about the Goodyear G272. They said they have run those on a few flu419s and they defiantly drive better but rub just a bit at full lock. My question is has anyone else here run the G272 (12.00r20 size) on a 406 or 419 and what did you think? Also why is a 12.00R20 G272 taller than a 12.5R20 XL. It seams like all the 12.00R20 tires I look at are taller than the 12.50's doesn't make sense to me.

    They are 44.7in tall g272s in 12R20. Your 12.5R20 are measured differently being they are metric for 335 85 20.

    The metric size equivalent to 12.5R20 is 335/80R20, at ~40.6" diameter.

    Our 12.5 R20 Pirelli Pista´s are round about 40" dia. on the SEE 419.
    We have 14.5 in stock but we are emberassed about the additional height of the truck because the center of gravity. The centrifugal forces with this
    backup excarvator you have to consider. And they build more and more Trafic circles in our area.
