Xd series rockstar II. 285/70/17 mastercraft courser mxtattachicon.gifimage.jpg

 

What exact size are these Rockstars?

I need 17 inch wheels but I cant figure out any other part of the wheel setup. mainly the 6x5.5 or 6x4.5 part.

 

What offset were your wheels and did you have any rubbing issues? I have a 4x4 crew cab with 2.5 inch RC lift on 33" cooper AT3s. I've never upgraded wheels on any of my trucks.

Thanks!

The 6x5.5 or 6x4.5 part is the wheel bolt pattern

 

The first number is the number of bolt holes in the wheel or the number of studs. The second number is the diameter of the circle formed by the lugs (or bolt holes). These vary by manufacturer, GM, Ford, Toyota etc. For gm trucks, most models any way, they are 6x5.5 or 6x139.7 Same thing though, 5.5 inches or 139.7 mm This is for the half tons anyways. The HD's are 8 lug and are therefore 8 x diameter.

 

So, for your truck, you would need a 6x5.5 or 6x137.9 bolt pattern. Be it 17x9 or whatever you choose. Also playing into your decision is wheel offset, backspacing, tire brand and actual size, but there is a lot of options covered in this thread of various sizes and combinations that should lead you to a good fitting setup.

what is everyones thoughts on 18s vs 20s?

i still havent gotten my rims and tires because i just cant make up my mind. i love 20s but dont want to handicap the trucks offroad ability....even though its going to be on pavement 95% of its life.

ive got the 2.5 RC lift, going to install it once the weather warms up.

If i were getting new wheels i would go 18s just for cheaper tires...why would 20s handicap the off road ability of the truck?

 

I mean i get it more rubber, but are we talking like serious offroading/rock climbing etc. or just hitting some trails and farmland every now and then.

no farmland, and not rock climbing. but the roads by my cottage are dirt and old decommissioned logging roads. some are ok but some are a lot of mud with a few hidden rocks and logs here and there.

others are technically ATV trails but the sierra made it.

 

the price between 18s and 20s is only about 25 bux a tire and rim...not a huge price jump. and ya its the sidewall issue im concerned with.

If it's a concern at all i would go 18" hell maybe 17".

Planning on leveling with a Nitto Terra Grappler G2 285/50/22 tire. Ive wanted these 22s forever and I finally found a heck of a deal on a set so I jumped.

 

Also my nfabs will be for sale also.

Pls do! I'm considering the same and would love to see how it looks. Some OEM replica 22s with 285/50/22s or 295/55/20s with the new Fuel beast wheel that should be available in a month or so

So...just saw this, Toyo is releasing more sizes for the RT. Honestly i'm left scratching my head. We get two more sizes offered in 20" wheels and it's 35x12.5x20 and 37x12.5x20. Why wouldn't you go to a more common size tire that appeal to a larger audience, rather than a niche tire size like 35" & 37". I mean i've been settled on 295/55/20 Toyo MTs for sometime but told myself if they got the 295/55/20 or even 305/55/20 RTs out i would go with them. Yes there is 33x12.5x20 but i'm under the impression that would take some serious offset to run.

33x12.5x20 and 305/55/20 are the same size. Both are a 33x12.5. It's just in how a company chooses to advertise the tire. Also they already had the 35x12.5x20 out for the RT. That's not a new size but the 37" tires and the 35x12.5x22 are new sizes.

 

I apologize in advance and if I am wrong about the 33x12.5 and 305/55 being the same then someone pls correct me.

Mostly right. A 305 is only 12 or 12.1" wide.

Ah i apologize. Whenever I have seen a 305 tire it is usually 12.5 manufacturer spec Edited by Mike1220

Well technically speaking it varies per manufacturer. I mean by default spec a 295/55/20 is 32.8"x11.61"x20, Toyo's measurements however for their MT 295/55/20 are 33"x12.2x20. I really just wanted to see the RT in 295/55/20. I don't think ill have enough clearance to run 305/55/20s and honestly 295/55/20s will be pushing it i believe.

 

I mean we're talking tenths of inches here and there per manufacturer difference to default spec but it is indeed a difference. I had just read that 33x12.5x20 rub with stock offset on the 14s. Also for some reason i picture 33x12.5x20 being a fat looking tire, which i don't really want. Want a balance between the two. Like my friends 285/70/18s, granted it's a 34" tire it being 11.5" width looks perfect.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I think an OBD-first proof is probably the right next step. I agree that the value is not the hardware box by itself. The marketable part would be the software: always-on capture, baseline learning, event reduction, system-specific reports, and alerts. Also agreed that if an OBD device is always plugged in and has local storage, it should not miss the event in the same way that a scanner plugged in after the fact would. The only thing I would not want to assume yet is that an ELM327-class device gives all the late-GM data needed at the rate needed. Standard OBD live data, DTCs, freeze frame, Mode 6, VIN, and calibration information are definitely the right starting point. GDS2 also proves that a lot of useful ECM data can be viewed through the DLC without needing a DTC first. The question I need to test is whether the data needed for a useful GM V8 event report is actually available through the DLC, and at a useful sample rate: - misfire counts / roughness by cylinder - AFM/DFM state - oil pressure and oil temperature - fuel trims - voltage / reset context - U-codes and communication events - calibration / software information - whether these are standard PIDs, enhanced DIDs, Mode 6 data, GDS2-only data, or not available So I think the right benchmark is: 1. Build the OBD-only version first. 2. Keep it plugged in and logging locally. 3. Compare it against GDS2 / freeze frame / HP Tuners or another higher-end logger. 4. Measure which parameters are available and at what update rate. 5. Only justify ECM-side hardware if it captures useful evidence the OBD version cannot. So you may be right: the consumer product might simply be an always-plugged-in OBD event recorder with much better reporting. A question for you: when you say ELM327 devices can already deliver all the data needed, do you mean generic OBD Mode 01 data only, or GM enhanced data as well? For a useful GM V8 report, would generic OBD data be enough, or would you expect the tool to include enhanced items like misfire by cylinder, AFM/DFM state, oil pressure/oil temp, U-codes, and calibration information?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.
