E-rated tires slippery?

Hey guys,
Recently purchased a 2015 DCSB TRDOR. Truck came with toyo open country Xtreme E-rated tires. LT285/65R18. Running fronts at 30psi, rears at 24psi, that's what the pro rated math gave me, plus a pound or two. On fuel hostage rims if that matters. 5/16" of tread above the wear nubs. Got an alignment after I bought it, again if that matters.

What I'm noticing is the truck loves to slip and slide all over when taking turns even as low as posted speed. Even get tire squeal around a simple 90 degree turn at 25-30 (which is posted limit)

Truck is stock weight with 1" tophat spacer upfront and a 1 inch block in the rear. On stock springs and billies.

Is this a common problem? Am I being stupid? Looking for some wisdom before throwing money at a problem with a new set of tires...

 

It's those load E tires, i had the same issues when I was running Mickey Thompson ATZ's in load E. Even airing them down did no help. Now that I have a load C rating tire on it is night and day with road grip, especially in wet weather.

 

I got the same tires, yes they are slippery.

My truck goes into 4WD as soon as it starts to rain.

On the plus side, they will last a true 80,000 miles.

 

I have Es on a first gen. So certainly much lighter. While they ride like cinder blocks over sharp terrain they don’t slide at all.

 

Some tread designs and rubber compounds may be "slicker", but E load range tires are not the specific cause ....I have E Cooper STT PRO's at the moment. GREAT wet weather traction. FAR better than the C Duratracs I used to have...

 

My experience with original KOs in load range Es on my 1st gen was that they were like wearing rollerblades on an ice rink in the rain. I don't remember them being bad when it was dry, but that was years ago, maybe they did. I just remember they were absolutely awful in the rain.

My new truck came with load range E Duratracs. I didn't notice them being anywhere near that bad on pavement, even in the snow, though I put it in 4WD for the snow every time. But damned if I didn't have to put it in 4WD to get out of a level spot on my lawn when it was wet.

I decided to dump them ASAP while the getting was good (plan was to sell them on my 1st gen and sell its set separate) and get 17s so I could have a reasonable tire in between P-rated baloney skins and 10-plies. I ended up selling them for more than I paid for my 4Runner alloys, so I got those and new tires for a little less than just a set of tires, which themselves were way cheaper than 16s would be. Couldn't ask for it to work out any better!

 

Awesome. Thanks for all the replies guys. Seems a bit of a bit mixed bag when it comes to peoples experiences!

 

Are you actually slipping and sliding or do the front tires just squeal a lot?

 

My rear tires slide much more than the fronts, low weight makes sense. And the tire squeal also sounds like it's from the rear.
