it's all a compromise at the end of the day, were just trying to find the best one. at the moment the tyre of choice seems to be the toyo tr1, as a general all rounder. tyre weight is a tricky one as tyers themselves are a compromise as well. you want a tough tyre but also a light one. some time ago i had a set of SV stunner's which were stunningly crap they were quite light to be fair but so weak i never actually wore one out i managed to rip the treaded section of the tyer away from the sidewall, and that was just going round a roundabout sideways. fitting 280mm brakes adds quite a lot of unsprung weight but there worth it as they stop you so much quicker than 239's. tho at the moment i'm bumbeling round the suspension world in the dark tripping over things that don't fit. i think i know what i sort of want just no where sells what i want ( for syncro anyway )
