Continental MPT 81 tires on M35A3 ?

[dkconfiguration]

I was wondering if anyone has any actual experience with the Continental MPT 81 in 365 80R20 (43-inch Unimog tires) mounted on a M35A3 ? Can the same CTIS wheels be used or would you need everything replaced if not going with the original Michelins?

They will work fine

The stock M35A3 wheels are 20x11" MPT and fit perfectly, for those tires. IMHO, the 365 Conti MPT81 is the best tire you could possibly put on your truck.

I would've gotten the Continental MPT81s to replace my old 14.5R20 Michelin XLs. Unfortunately they were way outside of my budget, so I went with pre-loved 395/85R20 tires with 75% tread instead.

The 365/80R20 tires are a direct replacement of the 14.5R20 tires. Your CTIS will still work the same way.

Ok thanks, good to know. The original Michelin tires are very weathercracked all over, in the tread area, etc. They have more than half tread, hold pressure and drive great, but I would not trust it anywhere interesting worth taking, so need these Continentals.

One more thing - The local shop is good to go on doing the tire swap, but they couldn't remember if there is an o-ring on the wheel, and if it is 1/4 inch or 5/16 inch ? Is this anything to worry about?

When I did my truck's tires, I used these o-rings:

Rim O-Ring For Two Piece Rims on M35A3 / M939A2, 12363606

O-ring for M35A3 and most M939A2 truck rims. P/N 12363606. NSN 5331013147598. <br> 3/16 inch thick (0.19 inch). For 20 inch rim. Factory original OEM part, made in USA. For M939 series using a thicker O-ring see P/N 52-49529-00. Note: if the tire does not hold air this O-ring is likely...
