As the title states. I am looking into buying a set of AP2-V2s and I already have a set of new tires. I was wondering if the 235/45R17 would work for the AP2-V2s REAR wheels. From what I saw is that the recommended size is 245/45R17.

No the OEM size is 245/40/17. The 235/45 will fit but its not an optimal size.

Sorry,your right! Meant to type 245/40/17. What would you say are the drawbacks of running that set up? My front tires are 215/45/17, which i believe would fit.

The 235/45/17 is going to be a hair bigger in diameter than a 245/40/17. Not sure how much, but that could have a very slight impact on speedometer I'm guessing? A narrower tire in the rear means the car won't grip the road quite as well, and so the rear won't stay quite as planted as it would with a 245. Might not be too noticeable unless you push the car/tires to the limit, however.

Great, thanks for the info. I don't plan to push the car/tires to the limit.. yet, so I should be good with this setup for the time being.

245/40 =24.7" rolling diameter.

235/45 = 25.4" its a lot bigger and not a good choice in handling, grip, Speedo calibration or looks.

Dang, well I guess I'll have to live with it for the time being. I'm actually using the tires right now and I haven't had an issue. I was wondering more on how they would work with the AP2-v2. Thanks for the info, for sure will keep it mind for the future.

IMO, not a problem at all. The difference in grip on the street between a 245/40 and 235/45 is going to be negligible to nonexistent, and 2% bigger in diameter is not a big deal at all. I'd be more concerned about whether the tire make/model are appropriate for your wants/needs/usage envelope than the oddball size.

That makes sense. I got basically brand new Michelin Primacy MXM4 so they are definitely good for my use. Thanks for your input.
