Toad 4 Down 14, 15, 16" Any Difference?

[iRV4FUN]

I'm looking at getting a different toad. The different tire sizes available are 14", 15", and 16".

So here's my question:

When selecting a toad with 4 down, does the tire / rim size make any towing differences?

Toad 1 was a Saturn SL with 14s.
Toad 2 is a Wrangler with 17s.
The only difference was the weight.

No difference.

Our tow has 20" tires, no problem.

The only specific thing might be the height of where your tow bar attaches to the toad in reference to the MH hitch. A taller tire might mean less chance of needing a drop receiver.

THEORETICALLY...My theory anyway...larger tires on the toad might help mitigate the impact of any bumps you can't avoid. They should also run a bit cooler since they don't rotate as fast and have more air volume. My CRV tires run 10-15* hotter than my MH tires.

BTW...just a bit of side bar...my front right tire runs 15-20* warmer than my MH (5* more than the other 3 toad tires). Any guess on where MH exhaust is pointed based on that alone?
