Got a tractor on 520 70r38s set at 72inch centres. I have a set of 18.4 duals that will match but I'm concerned about overall width?

Anybody have any idea as to working it out?

I make it 3.4m????

I have had CNH Magnums on 480/80 r50's with an overall width of 3.1 m. Some tractors are too wide in the rear body though to get duals that narrow.

Ok I get it now. You're talking about just putting the 18.4 's outside the the 520's. Depends how much mud you get in as to how much gap you need, unless you run scrapers between duals.

I would agree with Multipower calculation.

Used to have duals on a 7840 with 16.9s, swapped the backs from side to side took the track from 72 to 60, then could get the duals on in 3m without cutting the spacer ring. I know it would be more with 18.4s but you get the idea.
If you could do this it saves a sh!t load of wheel adjusting with the centre to the rim etc.

Speaking of terra tyres. Deere on 72" centres with row crops outside and 520/70/38 with 340 outside measure a shade over 3m. Am putting on 66/43/26s, anyone got any measurements for these. Duals n mud not good. Might need Terras for first fert split n first spray this spring, way things are going
