i have an 05 636, i want to put new tires on. i have pretty much decided on michelin pilot power 2ct's. the problem i an having is finding a front tire in the stock size 120/65zr17. i was wondering what the best more common size to change to would be?
thanks for all the help!!

 

120/70r17 is a pretty common size....

 

If you want to stay stock just get the Pilot Power /65, and pp2ct on rear, being for some reason Michelin doesn't make one. One my second set, can't tell tell the difference.

 

yeah, the 120-70/17 is the most well known tire size in all of the tire manufacturers for DOT stuff. I hate mix matching tires to make it work. But a good point OMalley
