tire/wheel problem L2350 4wd

[dan1948]

I purchased sets of 7-16 and 9.5-24 ag on wheels to change the 13.6-16 and 24x8.50-14 turf on my L2350. The center hole and lug holes match on fronts (7-16) They are 6 on 6" with 4.5" center hole. The 9.5-24 have 8 on 8" lugs with 6" center hole (should be 6 on 6.5" with 5.25" center hole) I can't return wheels cause freight cost. Any input will be appreciated. Thanks. Dan
