Anyone experienced front tire wear like this? Pictures attached.

Mine is doing it all the way across not just on the sides. It's like a flat section the whole width of the tire but I think I figured out the problem..

The most obvious thing to cause the wear I'm seeing is shocks. This is what I've thought from the start, but it's a new truck (well 50k miles but I bought it new this year) Anyway, GM in their infinite wisdom didn't put shocks on the rear of the truck. You actually have to special order it to get shocks on them.. I've checked countless of these trucks new at the dealerships and haven't seen a single one with rear shocks.

Anyway, I think what is happening, is a combo of it being a long chassis, no shocks on the rear me hauling heavy loads and the front shocks are not strong enough for what the truck is tasked to do.

My thinking is with no shocks on the back, there is nothing to control the rear bounce. It's usually not bad, but when I get on concrete sections of the highway it can bounce really bad if the road is crappy. Say for instance like driving through Baton Rouge on i10 or i25 through Denver is horrible. (all that new road sucks ####)

Anyway, I think what's happening is when the truck bounces due to having no rear shocks, the front shocks aren't heavy-duty enough to counteract on the front in and I think maybe the tires are skipping a bit. Not noticeable when driving but I'm guessing that's what is happening and once it starts to wear the tires like that they just get worse.

Anyway, I have a local shop that deals with truck tires so I threw a new set of cheap tires on the front for now until I get the issue sorted. I'm gonna try putting heavier duty shocks on the front and air bagging the rear axle. the problem is no one sells an airbag kit for this truck so I have to make my own.

edit..

oh and for the record, I've figured out that Chevy is using international MD frames. I knew Chevy & international were working together on these trucks but I thought it was just a rebadge deal so international could sell a version of it.

The truck however has international tags/stickers all over it. I believe they are using the International 4300 chassis for this truk but I need to see one in person side by side to compare them. The truck is a 5500md but it's not just a beefed-up 3500 like Ford & Dodge do.

This truck has actual 10-inch truck frame rails or whatever size the bigger Medium Duty trucks use (I think it's 10 in). It has Semi size lugs for the wheels not normal light-duty truck lugs. It's an actual heavy-duty chassis which is why I liked it but they 100% dropped the ball on not putting shocks on the rear ends. I can't for the life of me think what the thought process behind that was..

 

Yeah, it's a 2019 Chevy 5500md, I guess should have posted that in my 1st post.. lol Overall I'm pretty happy with the truck with the exception of the rear shock thing. I do think I wouldn't be having this problem if they had put shocks on it. I've never even heard of a manufacturer not putting shocks on the rear axle before.. I didn't even notice it until I was on my 1st trip with it..

I got lucky on mine, I found a brand new 2019 that was never sold. Some company ordered a few of them completely blinged out with all the options, then Coronavirus hit and they never took delivery. I bought it in Jan of this year brand new with a $12k discount due to it being a 2019 just before all the computer chip stuff happened.

As for the transmission that's another good thing on it. They didn't use a modified version of the normal truck trans, they used one of the more heavy duty Allision 6 speeds. It had a PTO option and has a driveshaft parking brake which is nice for loading cars. It's a lot more like a F650 than it is a Chevy 3500...

It's the 2wd with the straight axle but that DEF filler sucks because it's on the passenger side.. So I have to sneak into slow truck stops and come in the pumps backward to fill the DEF.

It's a bit annoying though, I already have 50k miles on it and I still don't have it outfitted as I want. I have a sleeper for it and a semi 5th wheel sitting in the garage and still haven't gotten it all on the truck yet.. I keep joking that I'm finally going to get the truck set up then I'll sell it to buy a new one.. lol

As for the motor, I'm weary of having a DPF system on the truck but so far no motor problems at all. It does get an odd ticking noise at times though but supposedly that's normal they claim for the injectors.... With that said, I have a guy I haul equipment for from time to time who says he can make certain things go bye, bye for me it for me when or if I'm ready but he suggested getting 100k on it 1st.

Overall I think I'd buy the truck again, but I'd do a special order to get the optional engine-driven air compressor and get the factory air bags on the rear axle (that's an actual option even on the 5500's but it had to be special ordered)

 

The only thing people have issues with DEF is supposedly water can get in the tanks. It's not like quality is any better or anything.. The whole buying "bluedef" for $18/2.5 gallons is completely insane.. It's all driven by people knowing DPS systems are crap s they think overpaying for cow piss in a fancy box to stop the system from breaking. If I buy it boxed I just buy Walmart's generic stuff because it's around $7/2.5 gal which is pretty close to pump price.

 

I don't plan to delete it unless I have to. It will be if it gives me trouble and only if I intend to keep the truck very long term. Most likely I'll sell the truck in or before the 100k range TBH.
