While not critical right now, my front tires are weather checked. They are Firestone 21x8.00-10 tires and no longer available from Firestone (discontinued). Looking at any in that size, I do not see anything available. Does anyone know of or if there is a replacement tire? Appreciate any help/ideas.

Try "Surplus Center". They "had" 20x8x10 at one time.Although they were Wanda. Cheap. I know it's not the exact size you're looking for but may be fine if you're not 4wd.

My 4410 came from the factory with 27 x 8.50 x 15 tires. I wanted wider tires in front so I compared tires. Not all tires labeled the same are the same height. I found several sets of 26 x 12 x 12 tires that are the same height as the factory 27" ones.
You could look and see what options you have. There might be a different sized tire that would suit your needs.

I agree about the sizes and heights. But unless you have them in person,side by side it's kinda tough to know for sure. And you really got to have them mounted and aired up to know.
The consumer can only go by what's written on the tire and hope it's accurate or at least close.

Lets just say that I had a really helpful tire shop and they let me try tires on rims till I had what I was looking for. They've done this several times for me as I would end up wrecking tires. The last pair I bought were a 6 ply rating and I haven't had troubles since. It looks like this set will need to be replaced because the tread is disappearing.

I'd say you are doing the right thing in worrying about matching size for 4WD and particularly if you use it in a high traction situation. Might as well take the time to protect the drive train from the "shaft windup" problem.
BTW, you can always tell if you are getting too much driveshaft windup in 4wd because with too much shaft torsion, the 4wd lever will be excessively difficult to shift OUT of 4wd. "Excessively difficult" is hard to measure, though. That's because most manufacturers - especially older ones - do not use a locking mechanism to hold the shifting fork in 4wd. Instead, when you shift into 4wd, they depended on a bit of the elasticity from the drives shaft windup to bind the shifting fork and hold it in the 4wd position.
What I'm trying to say is that even if everything on you tractor is perfectly stock, it will still often take a bit of effort to pop it OUT of 4wd. And that's normal. It's deliberate.
Back to the tires... You can use a variety of sizes and treads. The spec. that you want to match is called "rolling circumference". All tires have this spec. and you usually can find it in the mfg's tech data. Or call them.
BTW, "rolling circumference" is measured, not calculated. It is not really related to diameter. It's a spec. all it's own, and has to do with the elasticity of the tire and how much it deforms from a circlular shape. I'll see if I can find some Firestone specs.
good luck,

Weather checked tires will go a long time... and can be tubed, so you probably have time to get the right one.

OK. Here's an old link to a Firestone catalogue shows that as a "turf and field" tire for compact & garden tractors.

It's what we call a "Turf tire" or R3. Flotation type mostly for mowing - although I like that tire on my own little tractor for general use.
Look at the rolling circumference or "RC" below. That's the number you need to match. Finding the perfect front tire can even involve buying new rims, but they are pretty reasonable for small front tire sizes. Rim specs are more or less universal across all makes and models....and the specs are stamped on the rim itself. I've successfully changed from turfs to ag type tires by changing rims and matching the RC.
