16 inch to 19.5 inch wheels

Hi All,

Searched the forum for an answer but found none. I know that other weight ratings will be exceeded but I really would like to up my capacity with a change to 19.5 inch wheels and tires.
Does anybody have any insight into this topic?

I did this with my 97 460 F53. I don't recall getting hardly any weight capacity at all. IIRC, all it really did was give me a safety margin in tires as the XPS RIBS were at max pressure whereas the 19.5 I went to maxed out at weight at a lower pressure. Search for Rickson.

You will have quite a gear ratio change when going from 16 to 19.5 tires.
You may find your engine operating at an RPM that is out of its designed power band when traveling at your usual speed.

Not necessarily true. There is a combination you can get that will keep everything the same as if running the 16" tires. I don't remember the specifics but again, see the Rickson web site. When I had them, there was no difference going from 16" to 19.5".

I put 19.5" on my Southwind 35P 1997 model, it had 16".
The 19.5 tires far exceed the weight capacity of the 16", a good safety margin.
My speedometer is exactly right according to GPS, it was a little off with the 16" tires.
The height of the 19.5 tires is just a little more than the 16" tires.
I have Sailun S637 Tires on the MH and they are GREAT!!!
Just got back from a trip to Big Bend, TX area and I really like the tires etc. Even helped the fuel mileage a little, due to Lower Roll Resistance...

I was wondering about that also. I have 16" rims on mine.
