Hey, I'm new to this site. Just put a 2.5inch RC leveling kit in my 2014 silverado 4x4. I really want to get 305/55r20 Nitro trail grapplers on some 20x9 rims +18 offset. I'm wondering if anyone has this setup and what kind of rubbing issues you have if any. I'd love to see some pics or even suggestions on the next tire size down that would fit if the 305s don't. Any help or suggestions would be great. Thanks guys

I would suggest the 295s. the Nittos spec out kinda big you can squeeze a 305 in it but your gonna have to do some trimming.

@Enthusiast...very nice truck! How is the noise?

 

I cant speak for @Enthusiast but IMO the tire noise for any tire on these trucks are less due to the new cab design and sound deadening engineered in these trucks. I don't even hear my tires till I get over 80 but I run a different tire. From experience I think the Nitto Trails are pretty quiet for how aggressive they are. Same goes for the Toyos. Although these are mud tires not ATs.

2.5"? Did you replace the rear block?

I have a 2" Zone front level and 305/55/20s on Fuel Mavericks with a +1 offset. Zip Tied the fender and don't rub at all.

I have bilstein leveling shocks @ highest setting plus an extra 1" block in rear, I keep debating what tire size to go w/ myself...nearly relegated to getting 275/60/20 Nitto Terra Grapplers due to being so close to stock tire weight, anything in the 275/65 size is LT 10 ply and weight jumps up to 57-60 lbs

 

Now I recently discovered that Nitto makes the Terra Grappler in 305/55/r20 which is listed as 33.2" tire (275/60 is 32.9" & 275/65 is 34") - they list two different weights for this tire which I imagine is 1 being LT the other being P or whatever, anyhow the 305/55r20's are ONLY 49 lbs - thats close enough to the stock Wrangler SR-A weight of 43 lbs that I wouldn't consider 6 lbs of additional unsprung weight per corner to translate into a noticeable drop in acceleration/mpg.

 

Except - only question would be: can I mount those on the stock 20" AT wheels, will I have enough clearance or will they rub, and will the increased width/contact patch equate to mpg loss despite the weight not being that much greater?

crushNchowda,

 

I have those Nittos in that size mounted on 20x9 +18 offset wheels. I am running a 2.5" RC leveling kit with 1" rear block. I have a slight rub in reverse at full lock on the inner fender liner that happens 50% of the time. Nitto calls them a XL and they measure in at 32.5" mounted on the truck at 38psi. They are slightly louder than the stock Goodyears, but seem to ride and drive better.

 

I went from 20mpg to 19mpg on my 30 mile commute that is mostly 55mph. Acceleration is not affected much.

 

I originally only had the lower spacer from the RC kit in (which gives 2" of lift) and the tires seemed to rub in the same spot, the same amount of time.

 

These tires will fit on your stock wheels, but will rub the sway bar and most likely the inner fender liner at full lock.

 

Overall, I like that these are not as heavy as the other options out there. I also tow a 27ft enclosed trailer (approx. 5500#) and they seem fine. They may not last as long as a 10 ply, but that is the trade-off.

      Mangoal or FitcamX OEM Dashcam?

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
