Yes.  Sorry in advance, everyone.  From my research on this board, the topic has been thoroughly discussed.  Many times, however, specifics aren't discussed (e.g. "Wrapped with 35" Ridge Grapplers").

 

I'm about to take delivery of my AT4 and one of the first things on the list are new tires.  My plan is to go with a 35" tire on the factory "AT4" wheels.  Research shows that staying under 12.5" (the max that most shops will mount on factory wheels anyway?) will yield the best results in no rubbing.  I also would like to keep the tires from sticking out past the fenders.  So, I turned to Nitto's page to see what was available and surprisingly found 27 (!) 20" choices with several being roughly 35" in diameter.

 

Here are a the ones I believe I have narrowed down:

LT285/65R20 E 127/124Q ---- 34.8" Dia ---- 11.5 Wide

LT295/65R20 E 129/126Q ---- 35.12" Dia ---- 11.77 Wide

35x11.50R20LT E 124Q  ---- 34.76" Dia ---- 11.42 Wide

35x12.50R20LT F 125Q ---- 34.76" Dia ---- 12.5 Wide

 

Stocks are 275/65/R20 for reference.

 

My next stop is to call a tire shop and get their opinion.  However, I thought it would be good to hear the voices of people running these first.  Are these the four that people are generally running?  Are there others in the 35" territory?  Some of these are "LT" (light truck?) rated but have higher load capacities than the non LTs - further complicating this......

 

Thoughts?

GMC 2500 AT4 standard bed here - I have about 12k miles on Nitto Ridge Grappler 295/65/20 on Fuel wheels with a +20 offset.  Factory wheels are +44 offset.  My suspension is stock w/exception of Bilstein 5100 shocks which offer nothing for height.  I had very very slight contact on the front liners, which I pinned back with a zip tie on each side.

 

So, that means my wheels are 24mm pushed outwards, or 0.945".  On stock wheels, I don't think you'd have any rubbing at all.

 

I recently ordered a 3500 AT4 SRW standard bed truck.  I'll be running the same size on it too.  Along with +20 offset again.  I'll stick with it cause I know it works and it looks awesome too.

The 295 is roughly an inch wider.  Will they stick out on stock (+44) wheels?

 

 

Actually closer to 3/4" and that is only 3/8" on each side of the wheel.  You won't even notice the difference other than a more aggressive tread.

I would definitely go at least 35x12.5  That is only 0.9" taller and 1.7" wider than the stock tires.  It will be a slight change, but not enough to have issues.  They won't stick out past the fenders because the stock wheels sit in quite a bit.

      Cold start Miss, oil in cylinder

      By asilverblazer · Posted

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
