Stock tires on my '04 2500hd are Lt245/75 R16 on a 6-5/8" wide rim.
I would like to put Goodrich All Terain T/A 265/75 R16 tires on these rims but the 265 tire specs call for a rim 7" - 8" wide.
the difference in tire diameter between these tires is 1.2".
I'd like to install the larger tires but wonder if there would be a serious or significant safety/performance problem because of mounting them on the smaller rims? I suspect I should just go with a stock size tire but I have seen this very combination (265 on a stock rim) on the road and it looks pretty good.
