Not another what tyre question...
Basically i have a 2.4 nobby nic for the front of my singlespeed once it gets mucky. This is going to get used in wales in a few weeks for trail centres with 130mm forks and then rigid once the wet weather sets in.
Im not sure what to put on the back. I want something that will last me till it gets really filthy mucky in winter and am unsure whether to go for a 2.25 nobby nic of racing ralph. Im leaning towards the ralph but im concered as to whether it will get good grip in the mud? I also do about 14 miles on road every tuesday to get to the club mtb ride hence with ralph is looking good.
Any help would be appreciated
