Motor home tire size? Can I up size?

[sugarray40]

I have a new 2019 Forester 3011 DS with the Ford E450 chassis

As I'm getting to know the in's and out's of my new girl, I inspect the tires. I notice that the load rating on the tire is not 10% above the axle rating and I find this concerning. Along with this, as I monitor my pressures, the passenger inner tire runs higher pressure and higher temp than any other tire. I am obviously worried about a failure

Does anyone know if I'm able to increase my tires to LT 245/75 R 16 from the stock LT 225/75 R 16?

You have to watch the space between the dual tires to up size. Look,at how your exhaust runs around the inside rear. That's why it gets warmer then the other tires. I was thinking about trying exhaust wrap to see if that would cut it down heat wise.

Thank You, I'll look at that.

Look at tire rack. There are tires now for heavier vehicles. Over 3000 each. Euro rating. Seeing that, I may try them after I wear out my Transports. Load E are 2680 lbs, these were over 3100lbs.

I spoke with my local Ford dealer, gave my VIN, and their records show the 245/75 R 16 as an option. I would like the extra weight rating, but I'll have to check clearance.

Do you remember which tire this was? I can find 3042 lbs in the 245/75, but nothing over 2680 in the 225/75.

Thanks

I put in the tire size and clicked, see all pages. There is also 235 75 R 16. I used my lap top not my smart phone. Can't get the same on the phone that I can on the lap top!

A friend of mine found out that the Continental Vanco Four Season M+S tire has a higher capacity. It is the 225/75R/16C. Single wheel 3195 lbs and dual wheel 3085 lbs.
He put all six on his Class C. After I again blew out a Michelin on the rear duals on my Class C, I put two new Continentals on that side. They are the same diameter as the Michelins. Soon I will get two new ones for the other side. I will see how these tires work out. The only thing that I didn't like is that they say made in Czech Republic.
