I just picked up my mo-ho from the dealer ... and they filled them to the maximum stated on the sidewall.
Also, on a trip earlier this year I blew a tire and the service that changed it,( thanks Good Sams) said I should keep the pressure at the max. My tires were at 75 and he filled them to 85.
I assume fuller is better? </div></BLOCKQUOTE>
No, fuller is no automatically better. However, it is better than even a tiny amount of under-inflation.
Use of the max pressure eliminates hte possibility of underinflation but may result in excess tire wear at the center of the tread, poor traction and an excessively harsh ride.
The tire manufacturers publish inflation guides for a reason - the best inflation is that which carries the weight while maintaining the tires designed shape (profile). The shape is important because that is what keeps the tread in proper contact with the road. When a tire is over-inflated, the amount of road contact is reduced, reducing tire traction, and it tends to be mostly at the center of the tread, causing wear at that point. The tire also has less flexibility to cushion bumps. The upside is that it will run a bit cooler in most cases.
Tire shop guys inflate to max either out of ignorance or to avoid any liability for underinflation. Always chack your pressures after a visit to a tire shop or even an oil cnage. It is likely that somebody did you a favor and checked your tire pressures for you, probably adjusting them to some number that is totally erroneous.
