Question on Tire sizes

[aron5]

I have a tractor with 12.4-28 tires on it and I see there is a coversion tire that is 320/85 R28

Will these fit are they the same size? will they mount the same lookslike these conversion ones are radials ?

320/85R28 is a radial conversion from the 12.4-28 bias size. It will fit and mount the same however they may look a bit different. Depending on your tractor and the rims on it which may be for tube type tire, you might need tubes in them even though most radials are designed as tubeless tires.

I've never liked radial tires on tractors, but it's becoming standard on new ones.
A new Firestone 320/85 R28 is $1,125.59. A new Firestone 12.8-28 is $545.79.

will the same rims work?

Yes, the same rims will work, but you should have tubes in the tires, if the rims were not for tubeless tires. If this is the Ford 2000 (you should always tell what machine you are asking about) that you have posted about in the past I believe the original tires were most likely tube type.
