My Question being some what of a Tire expert my self is ( not trying to cause a arguement just need to understand as tires I know, Mechanics not so much) in theory all you are doing is adding weight! and not a whole lot compared to if you had 250 lb passanger that rode to work with you everyday,if that was the case would it not be suggested to upgrade your brakes then? I think the bigger issue would be with rolling resistance and the stress on the CV and other components more so then brakes that are used infrequntly. Like I said Just wondering myself I Am Not a Mechanic.
