This might be the complete solution, you're pictures show 8 stud rims.

 

The tractor axles aren't valtra, all brands buy in axles mostly ZF.

Good spot Gareth! Really appreciate your efforts.

 

The hub holes are the wrong sizes but that's not necessarily a deal breaker.

 

I'll ask them how much they cost. I imagine it will be rather eye watering.

 

Will keep you posted.

They are 16.9 24. This is smaller than anything listed as appropriate in the manual and I have no idea if the ratio between front and back is OK for 4WD?

Would it be worth a call to Withams as they sometimes sell them and may know more of the specs.

Agreed, probably worth a punt.

TractorData.com Valmet 665 tractor dimensions information

WWW.TRACTORDATA.COM

The above lists standard 665 4wd tractor tyres as Front 12.4R24 and Rear as 16.9R 34.

Just be prepared for around a 3k bill for rims & tyres, but it's an expense that will be worth it and make a usable tractor.

 

Annoyingly, I sold my old front W10x24 rims last year for £200 without tyres.

 

Best also measuring the centre hub sizes and between bolts.

 

Rears 150 & 205 bolt, front 220 & 275 bolt are mine and exactly the same as the link previously.
