37x14.5 tires

So I have a choice to buy some 37x14.50r15 toyo M/T. But is a 14.50 wide tire just ridiculous? Heavy? Do they help with grip/mud? Hoping one of your guys have ran them before and can help me with pros/cons of such a wide tire prior to purchase. I currently have 15x10 wheels with 3.75" backspace. So would I rub?

Oh yeah. And not to mention parts wear. I'm only running a dodge 9.25" and a Dana 44.

Where'd the 44 front come from? If it's one of the aftermarket thick case/tube ones with C gussets you should be fine. If it's a TJ rubi takeoff it'll have D30 tubes and C's, which would be close to their limits on 37 x 14.50 tires. Ball joints would probably be the first to go, then maybe bent tubes/C's if you bounce it.

Also, brakes that fit inside 15" wheels are going to struggle stopping 37" tires. Given the wider track and more leverage applied by bigger tires, you may want to look into thicker tie rod, drag link, track bar options. What's your engine/transmission/axle gearing?

Not familiar with the tires but the 10" rims would concern me when it comes to airing down. The 10" rim "could" make it easier to pop a bead etc. Personally if you plan on a lot of off-roading I'd address the rims first. 15x8. Or 16x8. IMHO

My nitto mud grapplers are 14.50 wide and they have a lot of bite, I don't have to air them down as low because they already have a huge foot print

didn't.realize. Those were 13.50. Any issues rubbing the frame at full turn? I was highly considering the 365x75 km2s because they can be ordered through sams and are pretty cheap. Equivalent to a 38x14.5.

They rub my triple shocks but I don't think a coil and shock setup will have an issue

Guess I forgot to mention. It's for my ramcharger. So those axles are both stock. But it needs ball joints anyway lol. I figured brakes would be a hard thing. The rear is drum on this truck. Cause it's an 89'. I was looking into disc conversion and drilled and slotted rotors front and rear. And no track bar.
Engine is a 318. But it's cammed with shaved and ported heads with custom 360 valves and headers.
Tranny TF727.
Gearing is regeared to 4.56.

So as sinister6 said. The rim could make it difficult to keep the bead seated. What width rims are you running?

Ah yeah that's some rather important information considering most of us, myself anyway, figured Jeep forum you were talking about tires for your Jeep.

Since your looking for tires for you Ram I wouldn't worry about rim width unless you plan to air down a LOT!

Yeah my bad guys. And I guess that's a good point. I probably won't do such serious crawling in this rig. But I do plan to take it on some moderate trails once I get experience.
And with 37" and 4.56 gears and about 300 horsepower. Should I worry about power loss? Gas I don't really care because I get about 8 at best anyways.

Thanks. I was thinking about it and I knew it would be a good one. It's probably worth the money. Thanks for the heads up on the rotors! I'll mud quite a bit. So that's a good tip.
