You’ll be fine, I ran 33/12.5 on a 20x10 -24 offset with no rub, I’m running a nitto ridge grapplers now 305/55 and has to trim just a tad to keep from rubbing

Just wondering if theres much rubbing with 33s that are 11.5 wide.

As long as you’re not using stock wheels you’ll be fine. 2018 GMC Z71 4X4, Crew Cab Standard Bed, I put 275/60/20 BFG KO2’s on with a 2 1/4” level up front and added 1” rear then threw the BFG’s on stock wheels only to get both upper left and right UCA’s rubbing. Apparently, the level caused the UCA’s to have different angle causing the rub. I fixed it with new Fuel wheels with plus 18 offset. All good now!

So is it the height or the width causing the problem?

 

 I have a 2” level. Stock tire 275/55r20 (new) is 31.9” tall.   If I go to 275/60 r20, height is 33”.  

 

Ive been assuming as I am considering my next set, that wouldn’t be a problem.  Except to my already-inaccurate speedo.

This is what i did, front level with 275/60/20 cooper AT3 tires. I only rub the inner fender liner little bit when backing up and turning. I t can be fixed by zip tying the liner but i just didnt care to.

I have close to a 2" level and I will upgrading to 20" wheels and 275/60R20 tires as soon as I have the extra money.  I have seen several posts of that tire size with no rubbing on the many wheel/tire threads on here.

All I had to do was pull back the fenders, and they don't rub.   Your desired size of 33x11.5 will fit no problem with stock wheels.

That looks really good..is that a 2" level? For stock wheels, I think those look the best too.

I don’t agree, I put 275/60/20 BFG KO2’s on my stock 20’s and had horrible rub on both left and right UCA’s causing me to buy new wheels with plus 18 offset. Btw, my truck is 2018 which I’ve heard 2017-2018 have new designed stamped versions of upper control Arms (UCA’s). My neighbor has a 14 and put on Cooper AT3’s 285/55/20’s with no rub but remember his is 2014 model with completely different UCA’s. IMO, don’t do it unless you’re ready to invest in new offset wheels. Good luck!

Yes, 2" level.  Rear had about 2" raised as well from airbags for towing.

That’s why they fit, 2017 - 2018 have different UCA’s which create different geometric tolerances when leveled.

That's correct. I have a 2" level and my stock wheels and tires sometimes rub the UCA's when backing up full lock. Lifting 2" brings the wheels in closer to the control arms.

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

      By Atlas · Posted

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
