37s or 35s?

[swynx]

Next month I'm ordering 4.88 gear sets for the truck. Contemplating 37s or 35s. I can get 35s for same price I paid for my 33s. How much better will 37s be?

I only use the rig to go to the mountains. I don't mind 3.73 and 33s tho. Could I fit 37s with only 4 inches of lift? I still have fender left to trim. I've seen 35s with no lift so I assume I can. Although I do have an odd rim set I think

If you dont care about flex you can run some pretty big tires but you still have to trim for turning. Just get 35s they are plent big for these little trucks. 37s would be to much for a few different reasons.

Go big or go home!!

Realistically though, 35's are probably as big as you'd want to go.

ttb?


you can go 37 easy enough with a 4.0 and 4.88 with your intended use if you drive easy on the high traction challenges. i would think 35's would be more practical but 4.88 may be a bit revvy. with 35's you will have plenty of gear for a fair health 4.0.

What kind of tires?

Well I have plans to swap the 3.0 m50d gears in for a lower first second and third. And down the road it'll probably get a sohc. Also strength isn't an issue. Ill be running Dana 44 outers with chromoly axle shafts on the ttb. I only run mud and snow both are pretty forgiving surfaces.

The tires will be a cooper discoverer stt in a 35/37.

I was thinking that 35s would be enough but still not sure. The ride should be pretty low.

Long ago I heard this 'rule of thumb' that's not exactly scientific, but actually in most cases comes close to a gear calculator. Typically I use both the gear calculator on this site as the high end, and this rule of thumb as the low end when plus sizing tires.

But anyway it goes like this:

For every 1" in dia. of tire you add, it is like lowering your rear end ratio by 0.10.

So if you are ok with 33s and 3.73s, simply adding 37s would be like you now have 33s and 3.43s. Or to look at it in reverse, the +4" would require you to go up to at least 4.13s to keep it the same.

although now that I write that out that doesn't sound like a good combo at all: 4.10s and 37s

Again, this is just what I use to calculate the "minimum" requirement or low end of what you ought to do. I would also suggest using the gear calculator to figure out what it says to do as the high end, and then see what your range is.

But to continue on with this logic, point to be made is that your 4.88s and 37s should be comparable to what you have going on if not a little better than your current setup

Let me fix something.....

For every 1" in dia. of tire you add, it is like lowering your rear end ratio numerically by 0.10.

As far as gears go I know it'll be a lot better than what I have now. I was just wondering how much easier it is to run stuff over and how much better the traction is. Ill have to buy new rims for 37s

Why would you need new wheels for 37's?

I have 15 inch rims. I don't wanna go with a set of swampers and there is very few 37s on a 15. I need something that works great in the snow and the mud.

They don't make many 37s in a 15 inch rim. Alot of 17 inch rims. I need something good in both mud and snow.
