Ok, got myself new tires...how should I break these in? I'm tempted to push hard. What happens if you don't break them in properly? Thanks.

 

Tires don't have break-in time.

 

id disagree.
just lay off the hardcore stuff for a while.
no need to baby it, but just dont push it like there is no tommorow.

 

If you drive too hard too soon you may spin the wheel(s) in the tire(s)(the mounting lube needs to 'dry') and fubar your ballance...also there is a mold release agent(lube from the manufacturing process) on the tires that has to wear off the tread....and that may take a few miles...be careful

 

There is really no break in time on a tire. Yes, at first you might need to wear off all the crap that is on the tire before you go to the mountains, but that shouldn't take too long.
