Default Question about tire sizes for 15x7 and 15x8 Fuchs wheels

Ok fellas. I picked up a set of 15x7 and 15x8 Fuchs wheels and was curious what size tires I should run on those wheels. If these were 16x7 and 16x8, I would be putting 205/55/16 and 225/50/16 respectively. Unfortunately there is no 205/55/15 sizes in the tires that I am thinking about getting which are the Falken Azenis 615's.

Would it be ok to just run a 225/50/15 for both the fronts and rears given I have staggered size rims for street driving and autocrossing? I know the 225/50/15 tires are smaller in diameter than stock but that is the size that I use with the Toyo RA1's on 15x7's for track events.

225/50 R15 are standard on the 15x7 wheels we run in 944 spec.

you could go wider than 225 on an 8" wheel, but tire slection is very limited. Frankly I am not sure of any tires wider than 225 in 15" diameter that you could use.

Dunlop makes a 255 but that is pushing it. I am running 205/60 r15's on my 15X7/8 fuchs now but am going to go to a 205/50 fr and 225/50 rear for that good gearing when time and money permit and when I wear these out. However, if racing, always listen to Joe D. IMHO.

There is no way I can fit a 255 on the 8" wheel without sticking out of the fenders. I already know I am going to run a 225/50/15 on the 15x8 but I guess the only option is to go with the 225/50/15 for the 15x7 too. The 205/50/15 is about .8" smaller in diameter than the 225's and I am not sure if that is going to upset the handling of the 944. That is a possibility though.

why run 205 on the 7" wheel? Just run a 225 especially if you want to track the car.

225 on all four corners. Hot tip. Final answer for NA handling. My racer was not as fast in 2006 with 225/50/16-245/45/16 combo as it was with 225/45/15's on all four corners in 2005

Mental note for self: Go back to 225's all around for 2007.

i am going to buy 2 225's for my fron wheels, because for some reason the PO has 195's up front :/
