Re: 20" vs 18" wheels for snow traction

I have 20" Forteras for summer and 18" Blizzaks for the winter. Any winter tire will outperform summer or all-seasons in cold weather (< 5 C).
Now, because Blizzaks are available in both 18" and 20", both 265mm width but the 18"s are 60 and the 20"s are 50% side profile, I would think they would perform very similar in the cold. You would need narrower tires to see a difference in snow.

No comparison...the 20" stock combo is better. I've got the 20" stock Forteras and have driven a new JGC with the 18" stock Latitudes on hot asphalt and in icy cold snow conditions. The 20" Forteras are worlds better than the stock Latitudes all around and that has more to do with the tire tread/construction than the wheel size. I was going to get some dedicated snow wheels/tires but see no need as the 20" Forteras have been surprisingly good in the midwest snow and slush at all speeds. Now, if I would go off-road, I'd pick the 17" wheels for extra sidewall depth and use a different tire altogether.

Agree with both. Tires are made for specific purposes, so just make sure your using the proper tire for the right conditions.
