Tow dolly and wheel size

Update:

Since starting this thread, I've gotten a response from Roadmaster regarding my comment on Camping World's site. As expected, the dolly will work fine with our RAV4.

Camping World forwarded your below comment to me. The short answer is yes, the straps that come with the tow dolly will fit all of the sizes of tires you listed. Your tire will be a little less than 30" in diameter and a little less than 10" of tread width. The included straps will fit the 17" tire with some to spare.

I apologize for the confusion. As you know, wheel sizes are not ideal as a smaller wheel size can actually have a larger tire than a larger wheel size might. But short of listing hundreds of tire sizes, using wheel sizes is a time saving, albeit not exact, way of identifying most fits.

I appreciate your query. If you need anything further, please let me know.

emblethen, Emails were to and from Roadmaster. When I asked CW, I got a firm "I dunno." ;)

rekij71, no to measuring the straps. The only unit they have is boxed, and I wouldn't use a unit the manufacturer says wouldn't work anyway.

I responded to the last email with basically what I've said above, and to their credit, they said they'd pass my suggestion along to engineering. But I'll probably go with the Master Tow unit when I buy. Right now, I'm sort of hoping to find a used unit, and my next long trip isn't for a few months, so I'm in no rush.

Common sense says you probably can as they should have stated tire diameter not a wheel size. RAV-4 tires aren't that big. I rented a dolly from U-Haul once and they said it wouldn't fit my off-road tires, but I still rented it to get across country on a move, and let the air out of my tires once on the dolly to get the straps to reach, then aired up when I was ready to take it off.
Can you measure the length of the straps to get an idea if it would reach around?

I would contact Roadmaster directly and skip CW.
