bought a set of et drag slicks that have 2 races on them for $50. guy was trying the height out and didn't work out. they are the size i need. 26-10-15. summit catalog says 9"rim. draglites come in 15x8 or 15x10. i have 2 sets of m/t drag radials on 15x8's now. will they fit or should i go with the 10"rims. i'm thinking 8's. any other suggestions.
