Stand back for about 50 different recommendations of tyres, all of which will feel exactly the same to you until you’ve been riding long enough to be able to discriminate. Spend your extra money on some basic tools, some spare inner tubes, helmet, gloves, a decent waterproof, small pump, puncture repair kit, some lights, as well as a saddle pack or a backpack with a drink bladder.
In a nutshell, narrow tyres around 1.6″ will roll a bit faster and cut down better in deep mud or snow whereas fatter tyres will run smoother and with lower ground pressure. Big knobbles will grip better in soft wet conditions but will be very noisy and slow and will wear fast on tarmac whereas multiple small knobbles or just a textured surface will be fine in most conditions and will roll much faster on tarmac.
