First of all, I was going to apologise for such simplistic (to you) questions and then I thought, no! Why should I apologise! There I was, becoming one with the settee, with a mince pie (or two), bag of crisps and a tube of Smarties quite happily watching Eastenders, Strictly Come Dancing, Take me out, and I'm A Celebrity when I accidentally found this forum. So by being here, you have brought this upon yourselves 
Anyway, current bike is a few years old Targa Viking DD 24 MB with huge great fat knobbly tires (and rider) on it. Although I actually love this huge bike, I have found very few mountains in Peterborough to justify it and, am considering re grading it as a road bike by fitting some narrower tyres. This will be a temporary thing as I have also decided that next late spring/early summer, I will replace the old girl with a Hybrid.
So, question 1. My current tyres are 2.3 R on a rim that has 559-21 written on it. I do not know if this is a size or something to make it look technical
I assume that a fair bit of the energy I use is expelled in just getting these wide, soft, knobbly tyres moving along the road so I would like to fit some more suitable road tyres that will still allow me to use the none surfaced cycle tracks, anything from earth to shale,that abound around Peterborough safely as well as make my commute a little easier (I am looking at a new route to make my ride to work 3 miles each way instead of the 1.4 direct route as a start to slowly building up my usage). However, I have no idea what size tyres I can fit on these rims, I have always just replaced them with the same type as when I first got it about 8 years ago.
Question 2. I have been looking around at bikes online to get an idea of what I will need to look out for when I start the search proper around March next year. I will never have a massive budget and will be looking around £300 to £400 max including any additional bits like rear rack (I like panniers rather than even a small rucksack) and mudguards etc. I am not looking for style but practicality and have found a soft spot for some of the Ridgeback range, are they OK for the budget I am looking at?
Any comments on the above will be appreciated but, like playing with a puppy, you may just encourage me to ask more so be warned
