Hey Guys, a friend of mine is looking to buy some Parnelli Dirt Grips, for his lifted Dually. Any info on these tires whould be great. He has a problem with some of the 35x12.50 tires being pinched in on the dually wheels, and the footprint isnt stayin flat, this has the tires cupping. Pics whould be great as well. He will be pulling with his truck as well, so info on how they do on the track would be good too.

 

I had those excact size tires Like the looks and that is about it. I only got 19,500mi out of those. NOT GOOD soft tire great tracktion but wair fast and they also cupped bad had to rotate every 2,000 seemed like and it was not enuff. Procomp Extream M/T's would be a good tire I use them in the winter and for sled pulling, Work good for sled pulling I think.

 

Thats funny, He has the Pro Comps, now, an starting to cup with just a couple thousand. What ply where the PJs

 

Dose he have the Extream seires. they are alot better tire. I have 20k on them and no cupping. I don't remember what ply the Dirt Grips were. There web site should say.

 

Yup, they are the XMTs, we both have them, mine is a single wheel his is a dually, I cant tell from your pic, is yours a dually?

 

no single tire, And let me tell ya I do not drive my truck like a grandpa my tires see some abuse. My best luck has been with the Extream A/Ts I put 46k on them and I sold them to my buddy, he has a nother 10k and still going. I would have bought them again for my summer tire but they do not make in a 22" rim. I had to go with nitto.

 

I had the XATs b4 the MTs, I only have about 2500 on the MTs as it is, But the ATs I had over 50k. I understand the ProComps are good tires, he needs something for the dual wheels.

 

yea he will need a narrow tire, unless he puts a spacer in or somthing.

 

ive got 36 k out of my bfg m/t so far but there getting there the trick for me was keeping the pressure low up front wich allowas them to wear even and obviously rotate but only evry 8 - 10k and they ride pretty smooth and yes i tow allot. wish she went in the mud more but fresh water mud is to far away

 

It is the width of the rim and tire pressure he is running that is the problem...no tire will hold up.

 

interco make a 35x10.50/17 in 10 ply i think it the radial ssr but not sure there was a thread on here not too long ago that showed pics and they look pretty gnarly

 

I have a friend that ran Toyo M/T's in 35x12.5 on his 07 dually with a 3" spacer, it looked wicked and he got 40K+ miles from them.

My brother runs toyo A/T's in 285 75 (thats right 75) on his dually with a 1.5" spacer it looks mean too. The 285 75's are nearly as tall as 35's.

I have hankook M/T's in 315 70 on my single wheel, 2 of them have 50K on then with 10% tread and the other 2 got road hazrad warranteed after I ran over a piece of metal on the highway. The don't cup on my rims, but I know dually rims are thinner. They are small for 315's though and look small next to most other 315's or 35's

 

Hmmm...rated at 3640 pounds. Interesting. Wonder how they wear...guessing crappy.

 

The PJ dirt grip 37x12.5R16.5 lasted all of 15K miles on my buddy's H1. The first half of the treadlife was about 12K, the second half only lasted 3K. He tried the Nitto Mud Graplers after the PJ's, they were noisy as hell and only lasted 20K. He's currently running the Nitto Dune Grapplers, after 10K they still look new.
