Looks like you have two choices. Both are 7.50-17, 8 ply bias. The STA Transport, Coker 710161 for around $190 and the Tornell Highway, Coker 71016 for $164. Either should fit with no problem. If you're running 2 or 3 piece rims you don't want radials. These rims require tubes, which are not recommended for radials.
Going by the pictures at
www.cokertire.com I would prefer the 710161, it looks like it will be quieter at highway speeds, if that is a concern.
The 710161 is also available from
www.millertire.com.
