How emberasing is that? Any ways. Is it cause of the type of tires I have? (Michelin X XZE 225/70R19.5 Front and X XDS2 on rears). Some one said these are highway tires. That I need wider off road tires. I only haul my 5th wheel 3-4 times a year so I don't really need the heavy load tire.
What tires do I need so that this doesn't happen again? I'd like to keep truck as close to stock as possible. I don't like spacers, or lift kits. Well I do but don't like the problems introduced by most of these mods.
Where I live there is mud roads, snow, and dirt roads. Ohh yah some paved roads as well.
Appreciate the help in advance.
Well, it is
and it isn't
your tires. I'm guessing that's and F450/F550 by the pic and tire size? With your 19.5" wheels and heavy commercial grade tires, that truck is set up to mainly be a highway tow rig with mild off road use. You may be able to find a more off-road traction patterned tire (the Goodyear GY622 is a good one, just $$$), but you won't be able to go much wider (maybe a 245/70 at the most and still have good dual spacing)....EVEN SO, because you're looking at 19.5" tires, the lowest ply rating you're going to be able to get is a 12ply, maybe a 10. With the GVWR of the truck itself, I wouldn't go lower than this anyway as you'll start to sacrifice load capacity. With the heavier ply, even if you would have dropped to 35psi, you probably wouldn't get that nice bigger footprint like you're looking for.
It'd be a lot of $$$, but the easiest thing I can think of to help you get what you want is get a different set of wheels/tires. See if a 17" or 18" set of dually wheels would clear the brakes, and get your wider, more aggressive 10 ply tire for those and use them when you're not hauling your trailer, then switch back to the 19.5s when it's time to hook up. I know it's not a great option, but with your truck and how you want to go about it without a lift or spacer kit, it seems the most reasonable.
Hope this helps
