As has been mentioned above, Specialized grid casing tyres have always worked for me. I’ve yet to have a sidewall failure (awaits catastrophic failure on today’s ride,😂), and I ride SDW for a fair proportion of my weekly miles.
I prefer an Eliminator upfront and slaughter rear. Both 2.3. Rolls well, reasonable weight but tough enough to withstand the flint. I also had a ground control grid which rolled really well, but took it off for winter as it had zero grip.
I use Mezcal/ Mezcal or Mezcal Barzo combo on the odd occasion up there on my Whippet but not sure Id trust the sidewalls on a one day sdw attempt. Not used them enough to comment to be fair.
