13” to 15” on 3225 tandem TM

[robtherod]

I have stock 175/80/R13 tires on my tandem 3225 TM. I know I need a 2” lift for height clearance to put on 15” tires. But what do I do about the tire width? Do I try to find a 175/80R15 ? From the 13” tire there is enough room to go to the frame without hitting it but the other side doesn’t have much room.
