ive seen where some people run a little higher tire pressure in their front tires versus the rear to account for the engine weight. does this really make a big difference in terms of even wear?

 

no not really...you will just wear tires out faster...your better off just running the recommended PSI

 

I would only run lower pressure in the backs if you never or rarely load the bed up. only to the point were the tread sits just barely flat on the road. otherwise I would just leave it to regular tire rotation to even out the wear pattern
