Hey guys,
I am replacing my stock continental 265/35/19 and 245/35/19's with the new PSS. The only issue that I am having is that Michelin makes a 245/35/19 for the front and they don't make the 265/35/19 for the rear. Do you all think that it will be an issue if I go with a 275/30/19 for the rear? Please respond soon as these are coming in the next day or two. I am primarily concerned with TPMS issues but any info would help. I contacted several retailers and all of them tell me that the PSS is not available in the 265/35/19 or the 275/35/19. Everyone swears that the 275/30/19 wont be an issue in any regard. Help please!
