4.1-18 or 4.6-18 rear tire size for XT225

This XT225 accessory site list the 4.1-18 as the size for a Shinko 244 on the rear. But I read of others using the 4.6-18. The stock size is 120/80/18. What is the advantage of either the larger or smaller size on the XT225. I have the stock gearing and original chain with 5000 miles.

The 4.6 will be closest in width to the stock tire, however the diameter might be different.

Will larger or smaller than stock serve to correct a speedometer error where to speedo reads faster than actual speed?

I just put a 4.60 rear tire (kenda 270) on my xt200, fits and looks good!
The tire on there was an off road knobby 4.10.

The speedo is driven by the front wheel on older bikes, some new ones seem to be driven by the transmission.
For front wheel drive speedos, the front tire only effects the reading, and going one size up makes it read close or correct.
Back tire only effects gearing.

On my TU250, going form 90-90-18 to a 90-100-18 makes the speedo read right in speed, and makes the trip meter read slightly low.
