new rear tires fishtail

[Ghost]

so I finally got some new tires on the radio end of my truck because they were 1/32. BALD.

now if I am driving 40+mph the truck feels like a boat or driving in sand. the rear end is very forgiving. tires are at max psi. they said this is normal for the first hundred miles or so... I need to be sure because every day I drive my new born son and daughter in law (age 6) around school, errands Park etc.

Tapatalk is gone. They started charging forums to have access with Tapatalk.

tires are at max psi

You saying tires are at the max pressure listed on the sidewall , or the max pressure listed on the sticker on the driver's side B pillar ?

they say 32.5psi when I use a air tool. is that correct psi?

 

[HARDTRAILZ]

Hard saying but a few hundred miles of wearing off mold release agents will make big difference

Bump your psi up a couple of lbs. The psi listed on the placard is for comfort...personally I run between 36 and 38 psi all round.

 

[littleblazer]

I agree with them getting better as you drive them. My tires were really slippery when wet for the first week or 2.

I feel a noticeable difference between 32 psi and 35 psi. I've always run 35 psi cold in mine.

 

[HARDTRAILZ]

You can guess anything, but easiest is to run a chalk test.

 

[Ghost]

I forgot to mention the tires are a different brand, not sure if that is an issue?

I pumped them up to 38psi damn it is it scary driving this truck on the freeway. I don't even want to drive it anymore. I am going to see if I can find someone to rotate the tires and put these new ones in the front and see if that changes the handling.

 

[Denali n DOO]

I run at 35 all around, winters n summers. In my opinion 38 might be getting up there try HARDTRAILZ chalk test. if I had two new tires I'd want them at the back.

 

[Tiggerr]

I can't ever recall have to "break in" tires. Idk what kind of tires you bought but I think I'd take them back. I'm also very OCD about tires lol. There are only certain tires I'll buy.

I've always liked around 35 PSI all around as well.

 

[NJTB]

Any chance you mixed radial and bias tires?

 

[littleblazer]

They wouldn't happen to be runway tires?

Are you sure this is an issue with your tires? I have never heard of or experienced anything like what you are mentioning with tires. It really sounds like a problem with your panhard bar, or a component in your rear suspension.

IMO you need to get the back of your truck off the ground and inspect all of the control arms, bolts, and panhard bar and make sure everything is sound.

 

[Sparky]

BT brings up a good point. Inspect everything back there. When I broke a trailing arm the back end of my truck wanted to go all over the place. Upper rear passenger broke first a few years ago when I hit something in the road and the axle would "wrap" (for lack of a better term) when hitting the gas, pushing the rear leftwards. Didn't help that my front end alignment got knocked all out of whack from it too (thankfully nothing bent/broke up there). That was fun, almost sent me into the side of the semi at 70mph.

Very lucky that your derive shaft did not slip out of the yoke. That would have been a very bad day. I have had 2 drive shafts break on me over the years, and it is very destructive and dangerous.

 

[Sparky]

Well the axle wasn't shifting around bad enough for that to happen thankfully (still had 3 of the 4 trailing arms intact, and the panhard).

I plan on getting a driveshaft loop on the Camaro one of these days if I was to ever go crazy with the car to protect against damage from a busted shaft. Or heck I may do it regardless.

If you swap front for rear to try the handling, be sure to swap them back as soon as you can. The best tires ALWAYS go on the rear wheels. This applies to front- and rear-wheel-drive vehicles.

Please let us know the tire sizes and brands front and rear.

 

[Mounce]

I thought the good tires should be put on the front because if a back tire blows out you're fine but if a front tire blows out you just about lose steering which would be bad at speed trying to get off the road and stopped. Humph. Just my view and what I was taught.

 

[Denali n DOO]

If you have more tread/traction on the front then on the.slippery shit the ass end might be coming around to say hi because of less traction and momentum wants to keep it going...

 

[Wooluf1952]

You might also check the D.O.T. born-on-date of the tires. Some dealers sell old tires. As tires age, the rubber can harden and traction suffers.

 

[Chickenhawk]

Yes, if there is a difference in tread or traction, the best tires ALWAYS go on the rear, no matter which is the drive axle.

Off topic but very important. It also refutes myths about front-wheel-drive cars, which doesn't apply to us but applies to our friends, spouses and kids who may drive them.

chalk test? explain!

OK so I'll have to make time this week to go back to the store and get this sorted. because my truck did NOT drive like this with the bald tires. maybe they are mixed with radialls. my front tires are more $ and are Goodyears and the back ones are some weird ass brand.

 

[Denali n DOO]

just curious, what is the weird ass brand?

 

[littleblazer]

I would also like to know.

Was this ever resolved?

 

[Tiggerr]

Idk if he ever got this resolved, but I just had a set of Blizzaks put on my Rainier on Sat. No symptoms like his at all. My suspension is shot, and zero issues. No sway or shimmy. Even with bad shocks in rear and the front end being a bit loose. Probably tire issue.

Pathfinder sport AT

 

[Chickenhawk]

Made for Discount Tire by Kumho in Korea and Vietnam.

Four different sizes of the Pathfinder Sport AT have been recalled due to possible tread separation issues. Maybe check your size against the recall list. Not the dangerous made-in-China stuff, but still made to be cheap and sold on eBay. The tread separation issue with the same model tire in four sizes does not speak well to the quality of the entire line. My opinion. I don't buy cheap tires, brakes or shocks so I have no experience with them, but would speculate this may be the cause of your problems.
