Tyre size

[mattydraw]

I’ve got a New Holland t6070 range command.its got 460/85R38 and 380/85 R28.the tears are 60%tread but fronts have worn quicker with it being 50k.tyre dealer has told me to put 420/70 R28 on fronts because they will wear better but will it be ok with the same rear tyres?

I'll post chart in a minute from pc but I know that's a straight swap as I have those on my 3
14.9 28 to 420 70 28
When you swap backs consider 520 70 38 as slightly wider option to 18.4 38.
