TIRES ON STOCK RIMS

[HHILL]

I just ordered a 2021 RAM 2500 and want to get my tires to put on soon as it arrives. Can I put Federal Couragia M/T 35-12.50R18's on stock rims without rubbing?

A stock 18" rim is 8" wide.

Most tire mfgrs will approve rim widths from 8.5" to 11.0" with a 10" rim being optimum. Federal didn't list a minimum rim width so they might fit.

I suspect with the stock offset you will rub inside at, or close to, full wheel lock. You can fix that issue with some 10mm spacers.

I'd suggest test fitting some tires to make sure there are no rubs at the front fender opening near the bumper too.
