Question:

I have a new 2015 Shasta 19 Airflyte trailer with Dexstar 15x6, with a 5x 4 1/2inch bolt pattern. The tire is 225 75R15. I would like to purchase a spare wheel and tire. Will this work: ST225/75D15 Bias Trailer Tire with 15inch White Wheel - 5 on 4-1/2 - Load Range D, Also, what do you recommend as a backup camera for a 2008 Dodge Sprinter 2500?

The Kenda Karrier ST225/75D15 Bias Trailer Tire with 15" White Spoke Wheel # AM32545 that you referenced would be the same size and would technically work, but since your trailer currently has radials on it I would recommend you go with a radial instead of a bias ply tire like what this one has.

For that you would want the part # AM32459. This tire is a bit more expensive but it would be your best option. It is highly recommended you use the same tire construction for all trailer tires.

The # AM32545 would work in emergency situations but it would not be your best choice.

The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire run at a 90 degree angle to the direction of travel, or across the tire from wheel lip to wheel lip.

A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear.

A radial tire will normally run cooler than a bias ply tire, especially when the tire is under a load. A tire that runs cooler will last longer.

The most popular backup camera we offer is the Hopkins Smart Hitch part # HM50002 so I would recommend it for you.
