Tires for 21" Rims

[Graystoke]

The staggered 21's make new tire choices tough. I've read a lot of owners have gone to the 245/35's front and rear. After researching a lot of tire specs I think I'm going to put 255/40R21's front and rear. Not much different from stock specs but
will give me a little more height from rim to ground. Has anybody done this? Would appreciate others Input.

I'm curious about this as well and was wondering if you can get them in all-season tires vs Z rated so that they last longer.

The tires i'm looking at are rated "Y" (186mph) speed rating, which is higher than "Z"(149+mph). I didn't check on all season treads.
.(2014 S P85D Metallic Gray, BlackLeather, all options except 3rd row seats.)

Make sure you actually check your clearances. Your choice is a 4% difference in revs/mile and is wider and taller than the specified 21inch tire. There is not a lot of clearance in the front wheel well to begin with.

Tesla does in fact spec the 245/35-21 as the non-staggered setup for 21 inch wheels.

There are many tires available in the 245/35-21 size. Are you trying to get a taller sidewall to avoid pothole damage? If so you should look at 245/40-21 rather than 255/40-21. To get similar revs/mile one usually ups the sidewall a notch and lowers the cross section. Not upping both of them. The equivalent tire to 245/35-21 in a 40 aspect is a 215/40-21. But no one makes that size.

What about going with all-seasons on 20 inch rims - Tsportline make a 20 inch rim for the Model S/X - 20

You can preserve the comfort, stay in spec and have a longer life all season tire.

Are you looking for a performance tire? If so, the Falken FK510 has good reviews and is available in the stock staggered sizes for around half the price of the Michelin PSS. I'm getting a set installed on Monday.

Your right the 255/40's won't clear front fender wells; It would of been a good size split between front&rear, plus more sidewall. So I guess it's staggered or 245's all around.

I've also seen the Falken Azenis in the staggered sizes. Tell us how they ride after you run them awhile.

Super curious too on the Falken tires. I heard great reviews on non Tesla cars

Just installed the Falken Azenis FK510's ,staggered 21s.on my S P85 D. Ride is smooth. I'll see how how they wear. For $800 mounted and balanced. not bad for a steel belted radial with a Y speed, and XL extra load rating.

Great deal! did you buy them online or at a local shop?

 

[Graystoke]

On line @ Tires-Easy.com. Had an RNR shop mount and balance they know how to take care of expensive wheels.
