Well as long as you don't mind a 10ply rated tire and the associated price tag and ride quality then the 275/65 is a good choice and because it's f250's standard tire size it's available from nearly every tire manufacturer and style
That extra half inch is another x amount of degrees on the cv axles which causes undue stress on the factory axle shaft.
If you have coil suspension the blisten leveling shocks are a better method though more expensive.
And you've got 33's from the factory! Congratulations.
With a leveling...
Well considering the wheel speed sensor hole and axle counters are on and against the spindle, and you're trying to grease the wheel bearing which is sealed and pressed into the bolt on hub, (which bolts onto the outside of the spindle) which then accepts the axle shaft where it is bolted to the...
Try as you might, I'm in salt country and I've never had an issue with a free moving part not being caked in grease. There's no contact there, so greasing it is pointless.
To each their own I guess but it's not doing anything except trapping dirt that would otherwise come out
So you purchased the h&s cooler kit as a simpler alternative with less points of failure, but you had no success with the simplicity of the system and in turn had more failures. Not cooling sufficiently because of limited air flow and no forced air or hd option. Failed lines, and now you're...
You have no leveling kit, no spacers, factory rims and you don't get any rubbing correct? Factory coil suspension?
What specifically is the brand tire you have out of curiosity?
If you've already added a leveling kit I'd assume you to be just fine, height isn't really the problem section width is what will make you rub. Only way you'll know is trying it. Worst case scenario maybe a 1/8 inch spacer would be necessary. Which is very inexpensive. Or if you're planning to...
If you have any reason to get a load rated truck tire a 65 series 20" rim is a great option. It's a half inch more profile on each side of the rim, one inch total larger, significantly deeper tread, they're readily available because it's Ford super duty's standard 20" tire size. A 275/65/20 also...
You're going to want to change your driving habits to lessen your idling and get up to highway speeds for at least 10-15 minutes maybe once a week is ok. And you won't see it. It's not hurting anything but it's letting you know there's a lot of city driving that's not letting it complete...
