Hi guys , I have the GBC 27" dirt devils , I love the tires for digging though snow and mud .. I also ride on hard compound ... coal trails ... with the devils on the front going over 40 ... they are devils , I know GBC dose not recomend high spees with these tires .
I have a spear set of wheels for the front of my prairie .
I would like to keep the 27"s on the back which really measure 25 ... but I would like to put mount up a pair of smoother running tires and wheels for the front .
The largest tire that is not too agressive is a 25 ... would you guys see any problem running the smaller tire .
I know all about matching tire sizes ... but a air pressure change can make all the difference .

Thanks guys

Greg
