I just ordered a vehicle that comes with all-season 21" wheels and tires. I live in the mountains in Utah, and we get a lot of snow in the winter, so I always have a different set of winter wheels & tires for our vehicles.
I’ve read that smaller wheels and tires perform better in the snow. Tire Rack has a page on this and I’ve seen it mentioned elsewhere too. I’m just wondering how significant this difference is, especially on a car with AWD and great off-road/snow performance already.
I prefer the look of 21" wheels/tires, but I’m considering sizing down to 20" for the winter wheels/tires for this vehicle to get better traction/performance in the snow.
