20" vs 18" wheels for snow traction

Hi,
Any perspective on whether 20" are going to be just as good as the 18" with GC stock tires?

Re: 20" vs 18" wheels for snow traction

The differences between the tires themselves (it isn't the same tire make or model) will be more significant than the rim size.

In theory, a slightly narrower tire will be superior in snow- it doesn't have to cut as wide a channel through the snow. However, reports are that the Michelins on the 18" rims aren't as good in snow as the Goodyear Fortera HL that is the OEM fitment on the 20" rims.

However, if I were to buy a set of winter rims and tires, I'd go 18" if for no other reason than reduced expense.

Re: 20" vs 18" wheels for snow traction

Those who have more winter than summer (our brothers in the great white north) also subscribe to the theory that the taller tire allows more "give" between the tread and the rim thus improving the "bite" they can maintain in the snow. I say this because I just sold my Touareg to someone from Ottawa and he was explaining it to me when he took delivery and we were discussing his options for winter tires.

Of course a great 20" snow tire will always outperform a mediocre 18" snow tire. In the above comparison it was assuming the same tire in different sizes.

Re: 20" vs 18" wheels for snow traction

If we're talking about oem tires, from all of the reports here, the 20" (Forteras) definitely seem to be getting a better bite in snow.

But which tires are you comparing them to? You have two different tires that come with the 18" wheels and at least one tire that comes with the 17" wheels.

I'm not comparing anything, I'm just echoing the reports of folks who've posted here with the 18's saying snow traction is shitty, and the reports of folks who've posted here saying the 20's are impressive in snow. Of course this is not a black and white situation, just a general theme.

18" Off-Road tires or "standard"? I have the stock tires on the Limited, forget which brand, etc. right now. Haven't had good opportunity for snow performance yet, but initial impressions were not that great.

Re: 20" vs 18" wheels for snow traction

Bottom line if you can afford a good Snow tire it will perform better than all season tires! So Good Snow tires on 20" rims (taller and slightly narrower) should out perform 18" tires.
Many of the guys on here including myself are lucky enough to be able to buy another set of rims and snow tires. Many have gone for the 18" rims for reduced costs and better selection.
Then use them for 3-4 months depending on where you live and change them out in the Spring.
I really like the Bridgestone Blizzaks many of us are using. Great traction on snow and really good on Ice (as good as you can control on ice)

Just my opinion!

In this case size doesn't matter, it's the quality of the tire that does.

Right, but like I said, the 18's come with more than one tire. And then there are the tires on the 17's as well...

I know the offroad package includes 18" Michelins. If you don't have the offroad package, you probably don't have Michelins, right?

I am glad you said that and not me!

Quality vs Quantity?
