I'm well aware that width and height of tire also changes the total diameter of the tire.
I have called 2 different dolly Manf. demco and roadmaster on their products. One has told me (demco) their dolly with Disk brakes is not legal for use in Canada.
and road master has told me is I have over 17" tires then not to use their dolly.
I'm now stuck with a brand new Roadmaster dolly that I have doubts about.
I'm new to owning a Motor home and towing a car.
Bruce, the emphasis on tire size is just misleading. A 17-inch TIRE is the type you would find on a ride-on mower.
Check Brockx' link above. My low profile tires on 18" rims are almost exact size (diameter and circumference) as a regular tire on 15" rims.
As I said, I have had NO problems with my Impala on the tow dolly.
I suggest you try it out:
- Load the car on the dolly
- Ensure the wheels are securely seated in the dolly pan
- Install the tie-down straps, ensuring they are centered on the tire both around the wheel and side-to-side also checking they are not contacting any part of the suspension (which may cause chafing)
- Ratchet the straps down as tight as you can and ensure the ratchets are in the 'locked' position
- Attach safety chains from the car to the dolly. I ran the chains through the front crossmember. In through the open end and out through the slot about 6 inches in from the end.
- Take it for a 10-15 mile run. Stop after the first couple of miles to ensure they ratchets are still tight.
After you have taken it on 2-3 outings, you'll get more comfortable with it.
I have just bought an Equinox so I can flat-tow. Not because of problems with the dolly but for simplicity of hooking up. I got tired of crawling under the car to hook everything up.
There are arguments for both dolly and flat-tow.
