16X8 rims with 285/75/16 tires. The tirewalls have a sidewall .4 inches wider than the rim (I think). Anyone expect any slipping off the lip?

FYI I don't expect to be doing any serious off-roading. Maybe riding a trail or two to a campsite.

 

Nope. You should be fine.
I have seen tires stretched to the limit and they never popped off.

 

Thanks, buddy. I thought that might be the case, but I didn't want to just go ahead and mount them. It would have driven me insane... Are my wheels about to explode?

 

Id def say if you only have half an inch then you have bigger problems to worry about then tires lmao!

but in all serious yes totally, you can even go up to 4 or so inches wider of a tire and get it to stretch and seat properly without blowing a bead, you will be fine. For instance 12.5 wide on 8 inch wide wheels, and so on, its run all day long.

 

Phew. I'm trying to get a lift installed with some big boy tires. I just don't know enough about these things to comfortably plow through and damn the consequences. Admittedly, however, I tend to worry excessively about things that aren't even real. Aside from unlikely explosions, I fret about accidentally downshifting from 5th to reverse instead of 4th and launching my transmission through the floorboard and killing my passenger.

 

Half an inch isn't much, but you may notice a tad more tread wear in the middle of the tire. To offset this, I'd recommend whipping around a few corners fast now and then, just to balance it out.

 

FYI, your section width (the sidewall-to-sidewall dimension) is 3" wider than the bead width of that rim. All tire manufacturers provide minimum and maximum rim widths for their tires. I'm sure that's within, since it's a tall tire, and taller tires have a wider range of usable rim widths. When you break it down, you're only 1 1/2" over on each side, and the bead of a tire is narrower than the section width.

 

The transmission prevents you from shifting strait from 5th to reverse, you have to take it out of fifth into neutral then back over to reverse, but you probably still would not be able to force it into reverse going fast enough to be in 5th gear.

 

Thats the wheel and tire combo I run and like everyone else has said its perfectly fine. 285/75 R16 on 16x8 rims

 

im running 33x12.5x15s on my ranger with the stock wheels that are 15x7 and ive gone mudding like once a week at the roller damn here in town and nvr had an issue but yes i do agree with some1 that posted earlier the middle wears out alot faster then the outside haha.

 

I've only put about a few hundred miles on them so far, so it's too early to tell. I'll find out before too long. Thanks for the input!

 

also keep in mind that the narrower your rim the less lateral support your tires, but the sidewall will not be quite as exposed to objects on the trail. Every tire size will have a specified range of rim widths it will fit, so if you go to the manufacturers site they probably have it listed.
