What do you guys suggest on getting more traction in rain for a 2 wheel drive short bed with 5 speed? I can't keep from spinning my rear passenger side tire when I go to take off and sometimes it'll even spin through third gear into 4th. I'm too poor for new tires at the moment and I have some sand bags I can put in the bed but I'd rather keep the bed empty unless I have to

 

My best suggestion would be to put some sand bags in the rear of the bed. Also try to keep your rear tank as full as possible. Weight is key.

 

Wow really? With stock gears? Let off the gas, man! If you're burning thru 3rd and 4th you must really be leaning on that go pedal.

Either that or your tires look like slicks, in which case there ain't much you can do.

Add weight to the bed OR lower your tire pressure a bit, nothing drastic, say maybe 5 PSI lower than normal. I wouldn't do both though.

 

See if I was laying on the gas that'd make since, but I'm taking off easier than normal road conditions and that back wheel will spin, so I'll back off and it'll grip up but when I go to get up to speed after that it'll just keep spinning. And it's a rather new tire. So I guess I need to put some weight back there

 

I was going to say that as tires get old, even though they tread the rubber gets hard (like an old pencil eraser) and they don't have any grip. But if it's a new tire it's a piece of junk, don't buy any more of them.
Some tires that advertise really really high treadwear mileage are basically like a hard old pencil eraser - they'd sooner slide across the pavement than leave a little bit of that precious tread behind.
That's all great from an advertising standpoint - your tires won't wear out for years. So you've got brand new looking tires on the truck that's sitting in the ditch cause the tires wouldn't grip the road.
Point is, traction is a trade off against tire wear - when you're buying new tires (eventually) the ones that advertise super long life aren't the best ones for staying on the road.
For now, a sandbag might be necessary. But also check your rear brakes and make sure your left one isn't hanging up. That could cause your problem too. Also your front brakes for that matter.

 

Exactly what tires do you have?

 

I think it's what chris_1 said. The tire that spinning is my spare so it barely has any use on it, but it's pretty old so it's probably hard. I'm ashamed to say all of my tires are different but I believe the one spinning is a Goodyear Wrangler SR A
