Do I need to drill into my trailer frame to install this?

Mounting method not specified in product data — test-fit the bracket against your trailer frame before committing to fastening. Most aftermarket mounts work with existing bolt holes, but confirm alignment first.

What size tires does this holder fit?

Tire size compatibility not confirmed in the product specs. Measure your spare tire diameter and width, then verify against the mount opening before purchase.

Does this come with bolts and fasteners?

Mounting hardware is not listed as included. Plan to source bolts, washers, and lock nuts that match your trailer frame thickness and existing hole size.
