TPMS question

Not really. I have taken them down some pretty crappy class IV-ish road around where I live. But that is only a few miles. However, so far: I freakin' love them. I wanted them mainly for offroad but I have been really pleased with the on road performance.

I had a Jeep that I offroaded for years but I find these Tacomas are a totally different deal. The thing about a Jeep is that it drives like shit (or at least my old CJ did) and does from the day it leaves the assembly line. But that takes a lot of pressure off of you viz messing with the suspension. How much worse could you really make it? (OK: a lot worse, but you get my point). The OEM Tacoma drove so smoothly that I was kind of seized by anxiety over the suspension decision. I didn't want to wreck on road performance. That's why I went with adjustable reservoirs: I figured they'd give me a little more room to work on on road performance too. Dang I like the ride.

 

I was reminiscing after writing that reply to you. In the old days with that Jeep I was pretty fearless. I just messed around with it and then whatever. Maybe it is getting older or something but I am just much more cautious with this Tacoma.

 

Its age and maturity. I used to mess around with vehicles and what not when I was younger. Nowadays, I just want it to work so I can go to work lmao

 

After the chalk test, measure pressure with your gauge (any gauge). It doesn't matter if it's right on or 10lbs off. But remember what it says. Then when you air up/down and check pressure with that same gauge, you'll know exactly how many pounds you're up or down.

Conversely, If you use a different gauge next time, check pressure before airing up/down. Then air up/down, say, 8lbs. Then you can use any gauge and put 8lbs back in later.

Actual pressure values are essentially irrelevant, assuming you dial in a "set point" with the chalk test. Am I making sense?

 

Yes, and it makes sense. Thank you.

 

After a bunch of experimenting this morning (pressure change followed by 2 mile drive) I am at 40PSI. Not nuts about the ride but don't hate it either.

 

I have to agree with you on this. I bought a Tundra yesterday with the same tires. They say 80PSI max. Nowhere in the tire does it say recommendation. Stock tires are 50 PSI max and people on here were so happy about 40-50 PSI hitting near the max. Logically why would I run way less than half PSI on another tire?

30PSI on my Grapplers (20" in my case) is way freaking flat. TPMS not happy either. I'm trying to figure it out.

 

Yeah, I think at 30PSI mine would really look low.

I only ran at 60PSI for maybe 100 miles so I figure any damage on them was probably minimal. I can't see any sign of any wear on the tires to tell you the truth.

I asked a friend in the tire business who I called this morning about the 60PSI and he said/joked "some would say too high, some would say fine....of course the right thing to do depends on gas prices, right?"

 

It is a “common” fact if you read up on tires, it is recommended that you fill tires up to the rated specs on the sticker on the truck. Your only running 2 sizes larger so you can go higher, if you wish, at own risk. Off roading is one thing, but street roading is another.

 

Also wear on the treads .... 100 miles? Most likely not. But you could have even wear that you don’t notice. Once a a tire starts to wear, it will “always” wear in that same pattern losing tire life.

 

I understand what you are saying, but at 35 they really look flat/low to me. (30 psi it is ridiculous.) The tires were at 36 from the Toyota dealership so 40 is not an outrageous number.

 

Yeah, 40 is good. Heck, even try 45. More pressure puts stress on the sidewalls and on the center of tread. 80 max on the tires is just a “warning” of sorts. To be honest though, I think 60 is pushing the envelope for trouble.

 

Suppose I ran them at 35psi for, say, 5,000 miles. A wear pattern would emerge. I would then inflate them to 70 psi. Run for 5,000 miles. Wouldn't a new wear pattern emerge? (Or, conversely, what if I have instead deflated them to 20psi?)

After around a hundred miles (maybe 130 at the outside) I'm not going to worry about it. I always viewed these Ridge Grapplers as kind of an experiment anyway (they are pretty aggressive and to the very end I was torn between them and KO2s).

Anyway, my friend told me that 45-50psi on tires like that on a Tacoma would be pretty standard out of most tire shops. So I'll experiment around that.

 

One thing I am going to do is document wear on these tires pretty carefully, and then probably report it back here. There doesn't seem to be too much long run info on these Ridge Grapplers.

 

One thing I can report positively is that these tires don't seem particularly hydroplane prone. With this bitch Florence in town I've had some chances to test that.

 

Naw! You can’t “even up” tires once they wear. If you change up the psi, yes a new pattern would emerge but it would conflict with the “wear” already there chewing up your tire faster. But yeah, don’t worry about it, you didn’t drive enough to hurt them.

 

Hope your safe. I live in a double wide and survived jean, Francis, Charlie, and Irma. Irma was bad. I know NC was hit pretty hard and prayers go out to all from my family.

 

Thank you. I am in Durham just north of the Chatham county line and we were pretty unscathed. Locally I think the rain might have been somewhere north of 6 inches but south of 10. Hard to say though when it comes in these intense bands. One or two big branches came down nearby, but as best I can tell no big trees. We might experience some local flooding, but I am pretty high up on a hill.

But the coast is a different story. Holy crap. Some of these places (like New Bern, for example) will probably take years to recover. Years.

 

40-45 should be fine for those. The sticker on the side of the truck doesn't account for different size tires.

 

no need to run E rated tires on a light duty 1/2 ton truck, if anything run the tires at or close to what the manufacturer recommends, a SL load AT tire would be more than enough load carrying capacity for normal everyday driving and offroading, having an E rated tire aired to 60psi would be like driving around with 4 -100 pound rocks as tires.
