Texas might need AG tires (only been there once) But, the R4's have a definite bite when needed, plus you can drive on a lawn without ripping it to shreds. (unless you are on the Bobcat, then there is no hope to preserve your lawn)
EVERYBODY needs ag tires.
If your lawn is too pristine for ag tires, baby it with a baby tractor. Don't keep a front end loader in diapers by denying it ag tires.
