Could you show pictures from back or front to see how wide the tires look? Also how much trimming was needed and does it still rub. Looking to get exact setup. Looks amazing

Has anyone run the Kenda Klever RT? Was looking at Ridge Grapplers, but the Klever also has a look I want.

Finally got mine done. 2019 Denali 4x4 with 2.5 front level and 1.5 rear level using SuspensionMaxx kit. Wheels are 20x9 +1 Fuel Rage D711 with 295/60/20 Nitto Ridge Grapplers. Had to do some minor trimming on the backside of the wheel well carpeting and a little to the inside edge of the mud flaps.

Update on mine for those that have been asking how the ride is. The ride is definitely nowhere near like it was and its actually bad in some cases. I was completely expecting a firmer feel and actually wanted a bit more feel to it. I’ve got this annoying issue with the rear hopping all over all the time. I've tried a number of different air pressures all the way down to 30 in the rear cold and no better. The front is butter smooth. Unfortunately in CA, every highway is under construction and with the new tires it’s just a rough ride all the time. I’ve had them balanced 3 times now and even had 1 tire replaced for being impossible to get balanced. I've also had the level kit checked to make sure nothing came loose and everything torqued and no issues there. I even called Suspensionmaxx and had them go over things with me just to make sure something wasn't installed wrong by the shop. One thing they and the shop I worked with pointed out is that with the ARC system, it could be that the heavy duty tires coupled with the stock leaf springs which will deflect a lot more are causing the ride control to attempt to constantly smooth things out which is in turn exaggerating things. 

 

I am now looking at putting Deaver leaf springs. Their design is such that it should smooth out any leaf spring based suspension as they use many thinner leafs vs a few thick ones and that on its own will remove some of the natural truck bed bounce we all have anyway. I don’t need it back to stock as I actually prefer a bit more feel of the road but it’s no longer comfortable to drive above 70. Local driving up to 55 is fine but once you get up to highway speeds on anything that isn’t 1000% perfectly smooth it’s pretty annoying.

I think you are onto something with the ARC. You have to keep in mind that your new tire/wheel setup is probably close to 25lbs more of unsprung weight per corner due to the LT tires so they computer is having a hard time keeping up with that amount of rolling mass and constantly trying to adjust.

 

Nitto does make the Ridge Grappler in a P Metric XL 4 ply 305/55/20 which is about 18lbs lighter than your current tire. Only about .6" shorter too. Might be worth swapping to those - your ride quality should vastly improve.

I was running the 22s so this new setup is only about 12lbs more per wheel vs 25 but yes they are definitely heavier. I had originally looked at those 305/55s and while they are about .5 inch shorter (The 295/60/20 is a 34x11.5) they are also nearly 1 inch wider and there were concerns about rubbing with the offset of the wheel I chose - 20x9 +1 offset. Running those would also get me under the weight of the stock 22s and a shorter tire but I will have to do some measuring to see what another inch of tire does with rubbing on the UCA. I'm already getting a minor rubbing at full lock with these so anything wider will probably make that quite a bit worse.

Went back and double checked the wheel and tire weights comparing the OEM 22s vs my new setup. Its actually a 19lb difference (Stock is 85lbs total and current setup is 104lbs) so quite a difference. If I change out to a 305/55/20 Nitto that will drop this to 89lbs so only a 4lb increase over stock but a 15lb difference with my current setup. I must have mixed up one of the tires when I was originally researching all of this as I was looking at a ton of different combinations. I also measured the current amount of space between the current 295/60 tire (runs at 33.9 x 11.77 width per Nitto) and my UCA and its right about 1.75 inches on each side and that was measuring off of the raised tread blocks. The 305/55 runs at 33.2 x 12.44 wide on a 9.5 inch wheel which I think will settle more into a 12.25 on a 9 inch wheel plus they are a bit shorter. Should be plenty of room and I have already done a bit of mud flap trimming to better accommodate the 34 inch tires on there now. Needless to say I went ahead and ordered the 305/55/20 Nittos today with the shop I use agreeing to buy my originals back at a decent price as they only have about 1,500 miles on them. I wont have time to get this done until the end of the week at the earliest but will report back once its done.

Finally pulled trigger on tire upgrade. 285 50 22s. Look so much better than anemic 285 45s. Are 10 ply so do ride harsher and I'm sure are sucking more gas...but look great none the less. Went with Radar Renegade AT5. Got great price on EBay.

Hi Mark,

Great looking wheel, any chance of directing me to some more information about them?

I asked this in the Mods forum but got zero response, can anybody answer?

 

I have a 2020 AT4 that came with the 18" wheels.  I'm going to upgrade to 20" after market rims with a +12 offset.  My question is can I go to a 285/55 or 285/60 without any problems?  The truck isn't leveled and I don't plan on doing it. 

thanks.

    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page 
    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
