I noticed that going to Tire Rack you can build a winter tire/rim package and it options in 255/70R17’s.

Maybe a slightly small diameter tire isn’t the end of the world??

Anyone know on here if it would cause issues?

We fitted the DAI Peak wheel on the truck and it barely cleared the front calipers.  Didn’t like it, felt like if a rock kicked up on dirt road and got into the rim it wouldn’t be good.  Basically 2mm to 3mm clearance.  Also the tire diameter from the original was down about 1.5” which I felt looked too small once on.  Luckily my tire guy worked it out with me and credited back the tire package and we ordered something in a 20” wheel.  Here’s a picture with the DAI Peak wheel.

Is that a pic of the 17”?

Crazy how a 17” barely fits nowadays.

Yes that picture is the 17” DAI Peak wheel.  It had no problem clearing the back but the front was too close for my liking.

Wonder if going at least 18” would be better especially sticking with factory wheels.

My gut tells me that perhaps the aftermarket hasn’t quite got it right yet for the new trucks and the bigger calipers.

Considering the AT4 has an option for 18" wheel on the GMC website I'd assume that would be fine.  Either a 265/70R18 (32.6" diameter) or 275/70R18 (33.2" diameter) are pretty close to the factory 33" diameter tire that came with the truck off the lot.  The 18" wheel would probably provide about a 1/2" space around the callipers seeing that the 17" just cleared them.  In the end I just decided on getting a 20" wheel for my winters using the Replika R204 wheel.  Got them installed today and they fit nicely.

Also looking at the Sierra SLE trim you can get 17” or 18” rims.(First 2 pics are the SLE trim)  The overall tire diameters are smaller on SLE’s compared to my Elevation with 275/60R20’s(33” dia)

 

My Elevation also has a full size 17” steel wheel spare that has a 255/80R17 tire, also 33 dia.(Bottom pic).

For a winter setup I’m thinking a 255 wide tire would be better.

am sure they all good, common sense if your in mud and snow a lot use M/T and if its more hwy and some snow or mud an A/T.....also look at what you see others in your area using.....I seriously doubt one is far superior, tho I will never use another Goodyear tire based on 2 bad experiences ( not performance related).....doesn't mean they are bad just wont do it again....got 90k out KO2 las time and sure toyo and nitto are similar...…whatever floats your boat and you get deal on...I would go bf Goodrich again as I have had good luck and like way they look.....

 

general, falken, etc list goes on and on....but one outshining another in a drastic way, nah....pretty competitive market

That time of year again when I’m contemplating getting a separate winter wheel/tire combo.

My truck was in for service so I popped over to the parts dept.  The lady there eventually called me and said she’d spent a good while sourcing out some wheels and tires.

She said “since it’s an Elevation with 20” wheels the only thing I could find with the same diameter would be if you stuck with a 20” wheel and tire.  These newer trucks are very (sensitive) to diameter changes and all sorts of issues can occur.  Needless to say 20” isn’t going to be cheap!”

I’m running slightly larger than factory 275/65 BFG’s daily and haven’t had any “issues”.

 

Anyone had issues going with a smaller diameter wheel/tire combo?

 

I don’t care about the speedo being out a bit!


End of the day my KO2’s performed extremely well last winter, they do have the 3 peak mountain symbol after all.

Think I’m more concerned about keeping the 20” Black Wheels in good shape more than anything else.  Winter tires are also far superior on ice as well!

Just a FWI, I've kept my snow tire/rims off my 14 silverado to use on my 19 RST and as previously outlined, they do not fit my 19 as they don't clear the bigger front callipers. Obviously the OEM 17s would fit, but whenever going with an aftermarket steel rim, they usually have a different inner profile. Definitely try before buying.

I understand that older rims don’t fit.

just wondering if reducing overall diameter will cause issues?

Going with a 20” wheel/tire winter setup is expensive!

    • Google converting 98 4.3 spider injection to carburetor if all else fails. 
    • That computer lies!
    • My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.  
    • The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.
