Terra Grapplers aren't wearing great - your experience?

My Terra Grapplers aren't wearing too great in my opinion, what has been your experience with them?

I purchased the truck used with 56k miles and I now have 61k on the truck. Most of the miles I have put on are all from highway. I do not know how many miles are on the tires but when I purchased the truck they looked pretty new and I am guessing they have 10k miles on them. The size is 275/70/18 in an E rating. I looked at them yesterday and it looks like they are about 1/3 worn and the fronts look worse than the rear. I will be surprised if I get 30k out of them with still usable tread.

 

On my wife's 4Runner I got 90k out of the G2s. On the second set now and the wear is great. Nothing special outside of regular rotation and staying on top of pressures.

 

I never ran the Terra Grapplers on any thing larger than a 4Runner/Tacoma. Never had any issues with wear. However it seems that on heavier applications they wear out much faster than they should regardless of the LT or Passenger designation. I remember many users having the same complaints OP on the 1/2 ton and larger trucks…

 

Mine have been great, no issues. I even bought my set for my Tacoma used that had 8k on them for $200

 

I had some on my 2007 tundra and they didn’t last as long as I hoped, maybe 45,000km before their performance really dropped off. That being said, I drive a lot of gravel logging roads at a pretty decent speed

 

What pressure do you run and have you had an alignment recently?

 

^

yeah, alignment might be a factor.

I run mine a 38-40 depending on the season. when I first put them on I had them at 35 and felt they had a little bit too much 'roll' / 'sway' to them when turning. pumped them up to 40 and they feel great. Maybe a little more firm of a ride but feel more control at highway speed.

 

Also where are they wearing? Outside, inside, middle?

 

are you rotating them every 5k miles and what air pressure are you running? Keeping up with rotations and correct pressure is key, as well and ensuring you truck has good alignment and any worn components are replaced.

 

I am rotating them and running @ 33lbs. They are wearing pretty evenly across and I even did the chalk test on them for inflation.

 

Well, if they are the G2, those have a 65k mileage warranty. So it you purchased them new and they dont last, you should have some $ coming back or a discount for your next set of tires.

 

I'm on my 2nd set of these in the G2's. 275/60/20. I run 44psi all around. First set wore even and great. Replaced at 62k. This second set is also wearing great. I'm on TRD Offroad coilovers, shocks and sway bars (front & rear).

 

For e-rated tires you want to run LESS psi than stock. Those tires are super stiff and WAY overkill for your truck. Just because the maximum pressure is higher, does not mean you should run higher pressure.

Get some chalk and figure our your necessary pressure properly on flat ground. I run mine at 26-28 PSI and I have about 800 lbs of extra steel on board. No cupping.

285/75 only comes in E which sucks but it's better than dealing with all the other bullshit to make real 35s fit.

 

I have the Ridge Grapplers on my Tundra. They have 20K on them and still look new. Most of my driving has been on pavement though. They have done very well and I decided to put them on our 4Runner as well. I have no complaints on these particular Nitto tire. I run the recommended tire pressure and rotate every 5K miles.

 

How regularly do you rotate them? I had 50k miles on a set of LT G2s on my 4Runner when I traded them in. Lots of life left. I was religious about rotations. Every 3k miles.

 

I had the same "mushy feel" to them at 34 PSI. I increased the pressure to 42PSI and they felt great until the rain came. I could not keep them under the truck in the rain. I figured I was not going to put truck and boat in danger of an accident let alone others. Sold them and went back to Michelin

 

What is this chalk test? I think I get the idea, but exactly how to you perform the test? Do you chalk an area on the tire? Or on the pavement? I can see how either might work.

 

Chalk the tire and then see if it wears evenly across.

 

That's kind of what I was thinking. Just never heard about it before.

 

this is incorrect, LT tires require more pressure than S load tires to carry the same load. There is a thread about correct air pressure in the stickies for the wheel/tire section here. Chalk test is best but this is an excellent tool to get you within a few lbs of correct air pressure when you change from stock tires to different size or load rating.

 

Alignment, proper pressure and rotating play a huge role. My Toyos with 45k miles have zero unusual wear on them.
