Tire Load

[bebelbrox]

I just prchased a 2004 S4-love it! However winter is coming and after reading a slew of reviews ripping the conti 2's winter ablities purchased set of conti extreames 235/40 18 90Y . I stupidly didn't check the load rating as these tires were advertized specifically for this car. I now note the large differential in load rating between the factory tires 95 and my new tires 90. Is this a major problem? I hope I haven't made a vey expensive error [img]images/graemlins/frown.gif[/img]
