Can anyone explain lawn tractor tire sizes
 

For example: 20x10-8. What exactly do these numbers mean and do I
have to get the exact size that comes with my tractor or can I get a
tire that is not as wide? Thanks

Got a flat? Have a tube put in. Cheaper than a new tire.

No I wanted to use these snow tires on my tractor when I have the plow
on. The normal rear tires are 20x10-8 but the snow tires I want only
come in 18x6.5-8. If the size is not too drastically different I
could get a narrower wheel. I was not going to dismount the snow
tires every season so I was planning on buying a used set of wheels
anyway.

Basically, that's how ALL tires - for automobiles, trucks, and
tractors - had their size indicated, long before the present globally
used metric system (P-400/50R8 might closely express that tractor tire
size in metric). A passenger tire might be P-215/65R-16. Light
Truck: LT-235/70-R17.

It seems that tractors have hung on to the old designation system.

20 inch outside diameter, 10 inches wide, on an 8 inch rim.

the same size.

A tire that is the same hight, but not as wide would be something
like 20X8 - 8
A taller tire could be 22X8 - 8

Unless the tire is so rotten the tube would just ooze out through the
sidewall.

I don't think you mean DIAMETER.
It's width.
I was talking about the pre-metric sizing. A 20X10 /8 lawn and garden
tire was 20 inches TALL, and 10 inches WIDE and fit a 8 ing diameter
rim. The sidewalls were roughly 6 inches high

In automotive P-Metric terms they would be something like a P250/60-8

Never mind. I guess it's OD, screwy way to do it.


In racing that kind of sizing made it very easy to figure out final
gearing, and to set stagger for circle tracks.
In offroad vehicles it makes it very easy to calculate, again,
gearing, but also ground clearances.
You KNOW, just from the first number of the tire size what the running
diameter of the tire is - you have 25" tires on your race car and it
is running 6000 RPM down the straight in top gear. You want it to run
7000 RPM - what size tire do you need? You want a tire 6/7ths the size
of your current tire - or 25X6/7+ 21.45 inches.
