ST1100 tire size alternatives

The new Michelin PR3 ( http://www.discount-motorcycletires.com/inc/sdetail/72/1918 ) comes in the proper size for the front of the ST11 (110/80-18) but there isn't an exact match for the rear (160/17-17). Take the survey and let me know what alternative size you would use, if any.

Thanks for playing!

I bought a Michelin PR2 in 170/60-17, and it has been working fine for me.

+10 on the 170/60 - They work fine even with an ABSII ST1100. Also, If you can find one, you can run an ABSII front rim on a standard ST1100 and then have all the fronts that fit the ST1300 (same size)
