that is a good point, however...

one thing to consider is that new tyres have larger tread blocks, simply because they are new and not worn out. LRR or not, all new tyres have larger tread blocks. this increases tread squirm. and i have read that tread squirm hurts fuel economy yet it reduces as the tyre wears down and the blocks get smaller, they squirm less.

so i wonder if the hybrid owners complaint might be partly due to having worn out LRR tyres with minimal tread squirm, and replacing them with standars tyres which have lots of tread squirm simply because they are new.

id love to see back to back testing of new LRR vs new non LRR in the various psi's i already mentioned. would be quite an interesting comparison.
