What Tyre size to purchase

[wiser]

I wish to change my off road tyres which are 26 x 2.30 to road tyres. To make the bike easier going but not sure what would be the correct and best width size to buy.

26x1.90 will roll fast something like these, cheap but cheerful..........you could go 26x1.50

Schwalbe Marathon Supremes roll well and have a tiny bit of tread for cycle paths.

Best part of eighty quid a pair, but good puncture protection cost money.

The width of your wheel rim will dictate the maximum ( and minimum ) size of tyre you can safely fit.
Theres a decent table somewhere at the bottom of this page http://sheldonbrown.com/tire-sizing.html which should help.

I've gone as thin as 26x1.25 (Specialized Fat Boys), but currently have 26x1.5 (Kenda Rain v-cuts). However, just in my experience but to a certain point, width isn't important (I had some tyres that were 26x1.25 that seemed -at least based on rough timing -to be slower than some wider tyres I used. I guess the tread just wasn't efficient). Also factor in tyre pressure as well.

I think 26x1.5s are usually a good size, and usually offer a good selection and value (and as Kestevan pointed out, if you have wide rims, your choice may be limited anyway).
