Fattest tyres to go on a 16" rim

[JCfarmer]

To replace some 460/85r38 tyres, what size/maximum width would go on these rims and have the same rolling radius?(tractor is used for cambridge rolling) Thanks

 

[C.J]

520/70R38

Some manufacturers may permit 600/65R38 - Michelin won't.

 

[C.J]

Kleber won't either.

They all seem to be spec'ing 18 or 20" rims for 600/65R38

I'm sure Michelin used to allow 600 on a 15" rim back in the days of the xm108 - I guess they thaught no one would buy low profile tyres if they had to buy wider rims aswell.

580/70/38 will go on a 16” but are larger in diameter

Bet ya would be shocked but a while ago i bought a tractor with 650/65-38 on 15" width rims.... yes you did hear me right....
Local Tyre Lad was well shocked when i finally removed them. The same tyres are on 20" rims now & just look so right.
i presume 20" would take a 710 tyre no bother?
Factory Rims on my 6480 are 18" i think & there 600/65-38

Got 520/70/38 dualled , the biggest influence to wheel marks where the fronts so put some wides on front , put the 800/ off old fert spreader as they matched backs ,looks odd but does the job

I used to have a 956 with terra tyres all round for rolling, she has gone and so have the 6.2m rolls. Now have a Maxxum 120 4pot and 12.2m rolls on 24m tramlines. Terra's for sale, open to offers
520 is as wide as I can go then with the same rolling radius as 460s?
Could do with a set of back wheels and tyres, maybe 600's.
Does anyone know the best place to buy second hand wheels from?

Mitas list 16" as a permitted rim for their both 600/65R38 tyres.

We used to have a tractor on 600’s and 16’’ rims and they looked awful- the tyre was clearly pinched in at the beads. Never had any problem with them though.
