I have a 997S Cab. and I drove every bit of rubber off the original rears. I bought a set of 305/30/19 Pzeros but later noticed that the Load rating on these tires are 98Y. My question is how soon will these tires blow up since they are not the right load rating??? I tried to search for the right load rating in the pirelli's in the 305's but I don't think they are available. I still have a lot of tread left on the fronts and do not want to have two different brands on the car. So should I go back to the 295's until the I can replace both front and rear at the same time to the Pilot Sports???

You should be OK...

The 305 Pzeros are just non Porsche OE (no N rating).

 

My stock PS2s are 102 (XL). I don't think that 4 ticks on the load rating scale are going to make a big diff, but I'm wondering why you went with non "N" rated tires... just wondering.

I have been so busy lately that I did not do my proper research. So here I am after the fact looking into it. The good news is I started the car this morning and the tires did not blow up yet.
