This is a post I made last April in a similar thread

https://www.rv.net/forum/index.cfm/fusea........d/29608055/gotomsg/29615202.cfm#29615202

Which is relevant to your situation.

**************************************************

If your rear axle is at or over the max weight, consider using one of these tires,

There is a new tire out there (I'll refer to it as the Euro C). it is designed for cargo vans.

The Continental version is called the Vanco Four Season. The size carries the C after the designation. Much higher weight rating than a standard LT tire. There only a few manufacturers producing the tire.

Edit, added new link.

Nexen Roanian CT8. Top four tire sizes in the chart at this link are the Euro C sizes (fourth down is your 225/75R16C)

***

OK, Michelin has apparently dropped the Agilis Alpin truck tires, so I edited and deleted this info.

***

These three tires (in the 225/75R15C size) all have the 3195 lb rating at 83 psi (single) and 3085 lb (dual installation), and have a load index and speed rating of 121/120R which is suitable to your MH.

To compare, the standard LT225/5R16E tire you are probably using now, has a single wheel rating of 2680 lbs and a dual wheel rating of 2470 lbs (at 80 psi inflation)

***

Not sold in the US market but available in Europe and Mexico is the Michelin Agilis Alpin Camper tire. Tread is designed for Motor Home use.

***

These Euro C tires are mandatory on the Ram Promaster as a standard LT doesn't have the weight rating necessary.

***

Another alternative is to switch to a 17.5 inch rim and the much heavier tire that is used on it.

Todd(?),

Your Bigfoot probably is built on the E450 chassis, so your great crawling differential ratio of 4:56 in 1st and 2nd gear will still provide plenty of slow speed pulling power even when using aggressively over-stock-diameter tires on it.

Just run larger diameter tires on it so as to get 1 to 2 inches of more ground clearance.

Try to keep larger diameter tires as narrow as possible so you can stay with the stock Ford 16 inch steel rims -> if and only also if 1) you can keep decent spacing between the tires in each rear dual set so the sidewalls don't ever rub at 80 lbs. pressure and, 2) you still have full front wheel suspension clearances so as to maintain the full turning radius and, 3) all wheel well clearances are adequate so as to not allow any tire rubbing from up/down axle motions on rough road surfaces.

BTW as I may have mentioned earlier, larger diameter tires wear longer too.

pnichols, I appreciate all of the feedback. I’m a fan of narrow tires, so no problem there! I’m, almost. ?? looking forward to buying 6 tires! Having the 450 chassis, with the low gearing, is definitely a plus! As said before, not looking for a “rockcrawler”, but 1 or 2 inches extra chassis height would be welcome! Thanks Again, Todd
