Doing some kind of Charadee run as have been roped into this by the missus.

Holds no fears but I need some tyres for the MTB as I don't fancy using off road tyres.

Have fat rims D521's so in short I need very cheap fast rolling tyres that will work on the rims any suggestions?

Kojaks are bald and meaty.

I've got somepart worn Halfords Kevlar tyres that are about 1.9 – 2.0" – you could have for £12 posted if you don;t find anything else. They're slick at the centre with a bit of knoblle at the shoulders.

Why not use your MTB tyres – it'll slow you down to the pace of the rest of your group. Its a ride not a race!

I just pumped my normal tyres up a bit when I did the BHF London-Brighton last summer which had the added bonus of scaring people I was overtaking with the wirring noise they made 😆

As above it's a ride not a race
