Seems like no one in the tire forum or Jim will ever respond to me query???

Anyway, it goes like this. Considering many people have upsized their rims to 17 or 18, I noticed that the lower the side wall profile of the tire, the lower the laod rating is. So for a 17 inch rim, you need a tire that is 205/50 for the front or else the rating would be 87. Same for the 18, the ones with profile of 35 just doesnt match up.

Does anyone have any problem with this, or should we all just put bigger sidewall tires instead of having low profile ones.
