Hard to find RE-11 sizes

Sig11'the 305/30's are shorter than 285/35's does it mess up speed in mph on the highway?

Read in another post that it throws the speedo off by about 4%

If you are going to do a 305/30R19 rear I would do the 275/35R19 front, fitment isn't a problem although the tire installers hate installing these, especially on the front stock rims (they're a bitch and not because of the size).

Tire rack doesn't sell old tires - this is an issue you run into with retailers. If TR has stock that is more than 1-2 years old they blow it out at 1/3rd price and advertise it as such.

My speedometer is 2mph fast at 68 according to my GPS.

I was going with the 265/35 because they only seem to have 275/30s which makes the fronts a good bit shorter than stock and the rear tires (25.6" vs 26.8"!) I guess I'm just not sure when that ratio becomes an issue but I would love to have that extra rubber in the front...

That TR info was exactly what I was looking for. Thanks, Chris!

Potentially I guess it could make the traction control more twitchy but on track that is typically off so it doesn't matter. Haven't given me any trouble on the street.
