Ordered my R with carbon ceramic brakes and 20 inch storms wheels. Anyone seen any specs on those wheels? Offset, wheel size, etc. I might like to replace the tires with PSS 275s up front and 315s in the back. Wonder if they will fit.

Thanks

 

I would think that the Storm wheels are at least as wide if not wider than the other stock 20 wheels.

Here is my post regarding tires for the stock wheels:

I believe the stock 20" wheels with the exception of the Storm wheels (fitted with the Carbon Ceramic Brakes) have the following dimensions which are stamped on the inside of the wheels.

Front 9J, 55mm offset, 255/35/20 tires
Rear 10.5J, 38mm offset, 295/30/20 tires

I read somewhere that the Storm wheels have a slightly wider stance so the offsets may be different (possibly to accommodate the larger brakes). Not sure about the rim size but they have the same tire sizes.

According to the specs for Michelin PSS, you could go to a max width of 275/35/20 on the front 9" stock rims. With the rear 10.5" stock rims, you could go to a max width of 315/30/20.

The XKRS-GT comes with 9J,10.5J rims also and has 265/35/20 front and 305/30/20 rear on it. According to the tests I've seen, those sizes work pretty well on it.

 

Just saw a set of Storm wheels on ebay UK and the width and offset are the same as the other 20" wheels for the F Type:

Front - Rear
Offset: ET55 - ET38
Rim Width: 9J - 10.5J
