So me like most others who are fairly new to the hobby, don't quite understand tire dimemsions...

Can someone help explain?

What's the difference between 23x10.50-12 and 23x8.50-12 tires? Width? Sidewall height? Overall diameter?

Maybe this could be a sticky so that it is easily found by visitors to the site?

Thanks

For garden tractor tires the first number is the overall diameter, second number is the width and the last is the rim size.

23 = Tire Diameter = 23"

 

8.5 = Width = 8.5"

10.50 = Width = 10.5" 

 

12 = Rim Diameter = 12"

 

I find that the cheaper Import tires really scrimp on these dimensions.  Some not even close.

A Deestone in  23x10.50x12 really means

 

22x9x12

I bought two Identical Hi-Run's 23 X 10.50 X 12 from TSC, and after mounting them, 12 psi each, there is a noticeable difference in the width between the two.

Just like clothes, all say same size, but sizes are different between manufactures. And 6 x 12 tire means , six inches wide and twelve inch wheel. No mention of tire height on that type of tire.

I would take both tires/wheels to them and ask them to replace one or he other so at least you had a matching set!

This is a really good thread. There is a bit of a grey area here, and standards don't exist

from one manufacture to another. (at least on the imports)

 

 

23 = Tire Diameter = 23"

 

8.5 = Width = 8.5"

10.50 = Width = 10.5" 

 

12 = Rim Diameter = 12"

Yep, that's the way I see it too.

I adjusted them with Air pressure, 10 in one 15 in the other. More for show than work.

and the real kick on those tires is they can be any where from 22" - 24" tall, depending on the age and maker of the tire.

Glad I am not the only one that has had that happen.

Deestone is off my list of tire suppliers.

Usually the air pressure for rears is 8# ..  Those tires are blown up like balloons!

 

The different size issue is solved by always replacing them in pairs IMO..
