I bought new winter ice tires for my 08 ranger 245/75R-16. they were a $100 cheaper each than the original 255/70R-16. they are a little narrower which gives them more pressure on the ground and less floatation and within 1% of diameter. I had them mounted on steel rims which whould save the aluminum rims from salt from winter driving. they where only $45. ea. I put on a complete set of 4.
