This is what 20's look like :P

 

My invo's were on backorder for about 3 months. My advice is to buy a spare set for the future

 

Back on topic i did a good amount of research about this,

It appears Michelin is discontinuing the PS2 315/25/19 due to lack of demand, and the new PSS tire they do not list in the 315/25 size.

Yokohama offers the Advan Sport in the 315/25, but again, appears to be discontinued, and I cant source them anywhere, and they don't list a production date for them.

From the current Continental selection, they do not offer a 315/25, but did in the past with their Contisport contact tire.

Bridgestone's current lineup does not offer a 315/25

This is what happens with a very low demand tire

 

There ya go:

Yes, they list the tire on the site, but retailers cant get these, and Michelin does not have a production date for when they will start to make them again...

 

If we start running 305/30/19's or 295/30/19's, what fronts will fit? Does anyone know if 225/40/19 will rub in the front? That tire would match perfectly with the 295's for revs per mile...

I currently have 235/35/19 front and 315/25/19 rear (Continental ContiSportContact) and got a flat in the rear yesterday!!!

 

I'm looking forward to getting a set of 19x12's within the next month. If the 315/25's are going to be hard to get, I may have to consider the 305/30 option... Any pics you guys could provide of the sidewall size?

 

245/35/19 should fit fine in the front and will be a better match with the 305/30/19...a 1.8% variance in rolling diameter.

 

I currently have Bridgestone RE11 with size 225/40/19 and 305/30/19 rear and they are fine in my car without fender rubbing problem.

 

That's my favor set up though but will 245/35/19 have fender rubbing issue?

 

Great news! Is your car lowered at all BTW? I am lowered ~1" with H&R springs, hopefully it doesn't make a difference...

 

Why would you prefer 245/35/19, larger contact patch? 225/40/19 is a much better match size wise...

 

I had rubbing issues with 305/30-19 Pirellis on the rear (plastic liner by boost hose). No issues since I went to the 315/25-19.

 

Yes! I have PSS 9 but it only lowered by 3/4 inch!. However, I think if you go for same size at rear, you can always adjust the height of you car!

 

You may be right, I am not sure. However, since I had GT 2 bumper, and all four GT2 fender liners first and then upgraded to 19" rims, I don't experience the same problem like you!




Because of this size of front tire will help my car to reduce the tedency of understeer.
