13” to 15” on 3225 tandem TM

[Shane826]

Someone on the TM Fans Facebook page swapped out their 13” wheels for 15” wheels on their 2001 3225 with no issues. I can’t remember what size tires though.

NO you do not need a lift kit to go from 13 to 15" WHEELS.
Tires with the same outer diameter are made for both wheel sizes. There are many many different size tires made for each rim size.
And even at that a 2" taller TIRE will only raise you up 1" as that 2" is spread around the center of the hub, so only 1" will be above the center and 1" below.
