Tires

[ceri23]

Can you fill a 18x8.50x8 .tractor has no loader & weighs 1320 lbs. looking to use a small drum mower that weighs 450 lbs

Yes you can fill those tires.

They likely can be filled. However I doubt that they have the "normal" liquid fill valve stem.
Such as this one for a tubeless tire;

Also with a volume of only about 2 1/2 gallons per tire the weight increase is not much for all the trouble.
Bolted on iron on the front of the tractor would be easier and likely faster.

Problem with a drum mower is that in the mow position and elevated (off the ground) the left front wheel is usually too light to keep it on the ground. I would suggest front weights in addition to any tire changes you are contemplating.
