Tire size

Thinking of buying used class c, 2012 ford e450, and tire size has been change from usual 225... to 245... which means it is wider. Will there be stuff space between the tires?

Welcome to iRV2.

Tire manufacturers web site will have information sheets on, rim width and rim spacing required for every size ; for dually installation.

One would hope that the tire shop that installed the tires , checked the chart before they sold/installed, the tires, as there would be liability in case of failure, due to sidewall scuffing.

I have studied tire charts a lot, and I don't see how there could still be enough space between the rear dually tires if stock rims were kept with the larger tires.

However, the difference between "getting by for awhile" and "enough" are open to discussion. On our E450 Class C I wouldn't go to those size tires using my stock rims.

I even went to narrower tires on our E450 some time ago to increase warm weather air flow cooling between my rear dual tires. My narrower-than-stock tires are the same load rating as the stock size tires, while at the same being a bit narrower. They are also a bit taller for more ground clearance in rough terrain and for crossing dips going into and out of parking lots.
