Will bigger tires wreck my transmission? Like 32 inch tires?

 

no

 

what do you have now?
are you planning on regearing?

probably not, i haven't destroyed mine yet and i assume we have the same ones.

 

Nope they sure won't.

 

it sure wont bud, mine came with 31's stock so 32's sure wont hurt anything! and im running 32's right now.

 

theres people running 40" tires and even bigger on the stock manual trans.

you will be fine.

 

the only time you need to think about re gearing with your truck is if your going to be rolling on 35's +

 

when you start dumping the clutch a lot like i do/did you may want to watch out for the spider gears

 

This is the worst general statement I've seen in a while.
Some rangers come stock with 3.55 or even 3.27 (I believe) gears.
You think it's okay to run 33's on 3.27 gears?
It depends on what engine, tranny, and what you intent to do with the truck. I would say, since he has a 4.0L and manual transmission, you would want atleast 3.73 gears. 4.10's would be ideal, and 3.55's would be pushing it. 3.55's will strain the clutch a lot more and make towing or hauling anything difficult. If you just plan on driving mostly empty and not over any big mountains, it might be okay. Not fun, but 'okay'.
I ran 33's with the same engine/tranny on my ranger, with 3.73 gears. It was 'okay' driving around lightly loaded, but pulling a trailer or hauling a lot kind of sucked. Had to slip the clutch a lot to get started on a hill, even lightly loaded. Lots of mountains around here too. Pretty much any four-wheeling had to be done in 4low, unless it was a light dusting of snow. Mud/sand/deep snow all bogged the drivetrain down too much.

 

I am running 32's on 3:55's and it isn't to bad.

 

32s and 4.10s is the greatest combo ever.

 

Running 32's w/ 4:56 and it isn't bad, but definitely need to upgrade to 35's.

 

how do you tell what gears u got?

like i wouldnt think that runnin 32's on a 2.3L w/stock gears would be a good idea...
