245 vs 275 Rear Winter Tire?

[renegrub]

So - I am going to have a winter 21" set for my P100D. Pirelli doesn't make a 265/35 21" winter tire to match the staggered setup of the summer tires. TireRack recommends 245 all around. But 245 on the wider rear wheel looks like a kid with too small of shoes. There is a 275/35 matching Pirelli winter tire but of course it is more expensive. Should I go with 245 all around or 275 in the rear? Thoughts?

I used the following Tire Size calculator and the 275 rear tires look a lot closer to the 265 than the 245 https://www.discounttire.com/learn/tire-size-calculator

Thanks for your help!

I thought Tesla got out of the business of offering staggered since the P85.

Is P100D coming from the factory this way, or are you staggering by choice and have selected wider aftermarket rims at the back.. is that right?

The Arachnid 21" wheels are staggered and come with 245 front, 265 rear.

I would be interested to know if anyone has come up with a winter tire solution for the 21” staggered rims as well.

The narrower the better; less surface area equals more pressure; more pressure equals better traction in snow/ice.

You won't worry about what the tire looks like from the rear if the front end is in the ditch.

If you swap for the season (months), then I’d go with 275. Yes, narrower is better in the snow, but it’s the (winter) tire itself that is of most importance. A winter tread pattern and compound is what provides the grip you need.

Buy two rear wheels and run square in winter? Thinner is better in snow and ice. Look at rally cars on snow courses vs dirt for proof. Yes the compound does matter but so does not having wide snow shoes.

My P100D came from the factory with the staggered setup on 21" grey turbines. Considering just buying a whole new set of wheels/tires for winter - probably 19" too. Then have the staggered 21" for summer.

Narrow is better for snow. I would also seriously consider finding 18" or 19" wheels and going to a minus 1 configuration for winter tyres. Just get inexpensive steel wheels - you don't want $2000 wheels getting salt and sand on them unless you plan on washing the vehicle 2x a week.
