Hi all I know this has probably been discussed countless times before, but here goes.. I am relatively new to cycling - have a hand-me-down full sus with deore xt rims. What tyres are best for sand-on-hard surface and plenty prickly-stuff (sekelbos/akasia thorns). I currently run Rubena Scylla rear, and Monorail front. Monorail have to be replaced soon. Any suggestions for R400 - R550? Should the Scylla go front? Thanks
