Lack of power with 20's

[ChrisK7UND]

Howdy,

So I bought a set of factory 20's and mine had 17's originally. There is a noticeable lack of power with these on vs. the 17's. Is it a computer flash issue? Meaning the computer isn't compensating for the 20's?

Thank you!

bigger wheel = more weight

I noticed a big difference going from esky 22s to 24s it sucks!

Yep more rotating mass to get moving......time for performance mods

or some forged (lightweight) rims

Okay, glad it's not just me. I only run the OEM 20's during summer and put my OEM 17's with all terrain tires in winter.

Thanks,

Agree.

it isnt the rim size that afffects the performance its the diameter of the tire
ill use mine for example i have 285/50r20 wich is a diameter of 31.22"
the stock rims and tires for my 2002 tahoe were 265/70-17 wich is a diameter
31.61" so you see even though its a 20 inch rim the same amount of rubber is hitting the road they have the same rolling resistance.

Wait till you roll 4's or 6's lol....with that said I'm used to it. I don't drive a hot rod I roll 2 tons of fun

I never noticed any difference between the 17's and 20's

When I had my 08 tahoe I went from factory 20 to KMC Slide 24's and I hated the change in power, braking power, and overtall turning. Went back down to factory 22 and now both my vehicles have 22's. Cannot stand the heavy weight of the bigger wheels (24's/26's+).

My 20"s rock.

You're good bro!

Heavy wheels suck and light weight 20's are expensive.
Either change gears, add a good amount of power, as in over 50tq to wheels.
Or just deal with it.

guess no one got the explanation about rolling resitance
all i know is my tahoe had 20s and now my suburban has the stock rims and the ride quality is so much better in the burban ill never get rims larger then 18s 20s and up yer ride quality turns to crap ive also noticed my alignment doesnt get outta wack so fast like it did in the thaoe

I had aftermarket 20's with Goodyear LS tires, went down to OEM 18's with Cooper AT's, new tires ended up being 11lbs heavier each than the old tires. Didn't really feel much difference

Mine seemed the same. Same tire size also
