I'm thinking about putting 20x9 rims (with 275/60 tires) on my '04 Yukon.
What effect will this have (if any) on towing? I have a boat that weights
about 3500lbs. It's seems to me a lower profile tire would not handle as
There is a HELL of allot more to handling than low profile tires. Putting
20" wheels on a full size SUV is like over-caming a stock engine. If
everything isn't matched, it don't work for crap! Putting those rims on will
do little more than vibrate screws and clips loose from the harsh ride, and
make the full size Yukon look like a distorted S-10 Blazer.
So you're saying the new Dodge Rams with the factory 20" rims are all wrong,
don't handle worth a damn and can't haul anything? Hmmm, interesting.......
I've never ridden in one but I see them all over the place. Can't be that
bad, I seen to recall seeing the Cadillac SUV's with 20"s as well. But maybe
those were all aftermarket.
No, he's saying that *changing* the factory rims will change the
handling or carrying capacity. DC and Cadillac have both designed the
suspensions so that they can use 20 inchers.
Quid quid latine dictum sit altum videtur.
(That which is said in Latin sounds profound.)
I simply increased the size of my tires from 265's to 285's and noticed a
severe performance loss in towing ability. The truck looks good with them
on, but now I miss the lost torque and gas mileage of a smaller tire...
Function vs. apperance... Hmmmm....
To me, 4x4 is functional. If you put big, rigid rims on, with low-profile
tires, you seriously increase your chances of breaking something when/if you
take it off-road.
The suspension components are designed to be buffered from harsh impacts by
a normal tire's ability to "give" from side to side. That's even more
important off-road. One little slip with rigid 20" rims could cost you a
rim, or damaged suspension or steering components.
I see these goofy-looking rims all over the place too. But, when you look
at the vehicle (and the driver) you can pretty much tell that it will NEVER
be off of a paved road. Most are "yuppies" who just want to say "Look at
me, I drive an SUV"... In that case, why does it have to be a 4x4? If you
were considering using it in snow or mud, low-profile tires will be
worthless. Try putting snow-chains on those rims. They'll be chewed up in
Yeah, it changed the gearing ratio... If you were running 4.10's,
it's not down around 3.97's...
My SS came with 20" rims. Aside from the wheels, everything under the
truck as far as steering and rear diff is concerned, is the same as a
regular 1500 series truck.
The manual says "no tire chains'. Too little clearance between the wheel
wells and the tires.
Within 400 miles of owning it, I had it offroad. The only thing I really
had to watch for was rocks jumping up and gouging the rims. It handled
everything as good as I could have asked. This was all on mild fire-road
type duty. Mostly just a rock-strewn erorded, mud holed, logged, TIGHT
dirt road. If I needed to anything more severe than that, I definitely
would have bought another truck. Hopefully, that was the only time I'd
need to do that this year.
The truck does SURPRISINGLY well in the snow. The large footprint
makes the truck float on the heavy thick stuff - it had no problem
getting up my slight inclined driveway, with 12" of snow on it. It's
definitely worse when it comes to 'stability' on the snow - it doesn't
cut through like a skinnier tire would.
The ride isn't all that much different from my '02 Avalanche with 17"
rims. It's just a bit tigher (the truck is also 2" lower), and corners
MUCH BETTER due to less side roll in the tires. In the Avalanche, I
used to run the tires overinflated (door sticker, not tire), to try to
fight side roll. This hurt the ride a bit.
In my opinion, 20" is the absolute biggest I'd go with a rim on a full
sized truck/SUV. There's very little comprimise when they're run on a
truck that rarely goes offroad...
The downsides I see - they VERY expensive. Tires average about $300
for decent ones. (EACH). The rims are HEAVY. Each wheel weighs in
around 75lbs. You really have to watch for pot-holes and how good you
are at parallel parking near tall curbs.
