Saw some 20" 8 lug rims for sale locally that came off a 08' 3500 silverado. My 2010 silverado rims are peeling and looking poor. It has 17" rims now. The new ones are chrome and appear to be perfect.
I use this truck for towing a trailer and will eventually plow my drive with it in coming years.
Any drawback to the 20" rims? Tires available in E rating? Same price or more? Snow and issue? Ride while towing any different?

be sure they are chrome and not chromed plastic. My dodge came with what I thought was chrome at 1200 extra(not my call) and they are just a chrome plastic over steel wheel. JFYI

That sounds terrible! Nothing last really well in Illinois. No use giving the salt a chance to attack

Outstanding. Thank you!

From my experience every time you go bigger in rims tires the same height cost more. When it comes time to replace tires I sure miss my 15” wheels as far as price of tires.

I passed on these after I saw them in more light. They had some pitting already and he wanted more than I thought they were worth. I own a 10 year old Silverado and a 20 year old one, both with rims that make the truck look older than it is. I don't want to spend a fortune to pimp the trucks out. Just want them to look more like new.

i have them on mine and it really causes an issue with the down shifting when pulling. The rear gear multiplication is not optimal for pulling a trailer and I am constantly going between final gear (not OD) and the next lower gear; and on hills dropping down several gears. This is a gas 6.0L 3/4 ton 2WD chevy crew cab

What does the rim size have to do with that unless you put taller tires on with the rims.

My 2017 Suburban has 20" rims (only because they were optioned on the only truck I could find that had the other stuff I wanted) but honestly I think the 18" aluminum wheels that were the base wheels in 2017 look better. I might try to find a set of the 18" take-offs when it's time for new tires.

Well still waiting for an answer on what the rim size has to do with truck shifting up and down differently.

My 1500 came with 20” wheels and part of the deal when I ordered was the dealer switching wheels with another new truck that had 17” wheels which they did.

The 17” tires were 1.4” shorter than the 20” and gained just over 200 rpm in the Tow/ Haul gear when compared to my friends same new truck with 20”.

Makes sense on the gear ratio. I even wish it had the 4.10 gear.

I saw the new silverado on Motortrend last night. Over 900 ft lbs for the Duramax and 10 speeds. Freaking fast too. And steering assist keeps tracking straight in windy situations. That camera deal that makes the trailer invisible is crazy cool. If only you could get it all without the $70k pricetag.

Well then the gear ratio change it due to taller tires not 20” rims. Might have to get taller tires because of the rim size but that’s not the real culprit.

Going from the 17" to 20" with the same width tires but they will also be taller and more roll out.

I would have assumed that a lower profile would be used to keep the height similar.

I would too. Referencing back to you initial post regarding "Ride while towing any different?", I think you could expect a harsher ride from the shorter sidewalls. But at the same time handling responsiveness would likely be improved due to less sidewall flex. Just standard tire stuff.
